Hi all!
In the past we have collected some demands we train heads have on driver
wheels. These have been requested several times at TLC so far.
Here comes the wishlist to make up a draft for a new driver wheel:
1.) technic axle center
2.) peg hole for connecting rods
3.) diameter bigger than set 7750 and smaller than set 396
4.) flange design similar to 9V wheels
5.) narrow gaps between two wheels
6.) distance between centers of two neighbour wheels in a common dimension
(4 stud / 5 stud / 6 stud?)
7.) running diameter dimension fitting to 9V and 12V wheel diameters
8.) wheel thickness higher than 9V and less than 1 stud (avoid contact
between moving rods and wheel)
9.) counterweight as click-on extra part, (if 2 moulds were possible)
10.) shape not 100% after real prototypes but kind of legoish.
11.) center stud with Legologo
12.) ((Extra wish -Additionally a wheel without flange (blind driver) should
be available.))
***************************************************************************
Solution: A wheel in diameter of nearly 5 studs (1 plate distance between
neighbour wheels) as seen in the following pictures. A round 1x1x0.33 plate
can be placed in the center.
The unofficial *.dat part-file of the wheel itself can be downloaded here
The *.dat part-file of the counterweight can be downloaded here
*************************************************************************
A first draft of an engine with these wheels has been done here:
(click to enlarge)
************************************************************************
Question:
If only one single mould would be possible due to too low demand and high
costs for new moulds, what would you prefer: Should the counterweight be
included in that wheel-mould or not? In case of only one mould being possible,
the users would surely obmit in blind drivers (since anybody could easiely cut
the flange off himself - better have a wheel with flanges than not having
it....).
Any further importeant points I missed in my design? I have put quite a lot
of time into this draft to make this new part as usefull as possible. So
hopefully you have not a too big demand for a further change in design.

Very nice, but unless youre doing some tricks I cant see in your image, your
example locomotive wont be able to handle corners.
You wont be able to put three of these wheels next to each other and have them
go around Lego curves. If you move the middle wheels in a half stud, I think it
will work - but that adds another layer of complexity with attaching the
pushrods. Also, if you want to run three wheels together, it makes a very tight
threshold for the shape of the flange. You need the flange big enough and
angled enough that it wont try to climb up the outside of a curve, but it still
needs to be small enough to fit through the switches.
My suggestion would be to just mold the counterweight into it, and make just one
mold. Off the top of my head, I cant think of a time I wouldnt want to use
the counterweight...
So, when can I get a couple dozen in black? *grin*

awsome!! dude this simply rocks.
Anyway a few minor points. Have it molded in black as it is more realistic in
the USA and in red for the Europeans. Also drive rods! I have never seen a drive
rod that is realistic to the squared off shape of the real thing. Other than
that what you came up with is exactly what I am hoping for. It is a simple
2-part mold that makes the wheel simple enough to be cheap to make and realistic
enough to have people asking where I got them.

Forget abou running behaviour for the moment: I just wanted to have an
impression about the feeling of these wheels. How do they look like in a LEGO®
engine.
For a real model it would need blind drivers or a steering mechanism like here:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=12161
As one can easiely see: this CAD-draft is quite similar to the LGB/Playmobil
wheels. Since those have been tested be me and others this decreases the risk of
failure.

Of course! But since I designed it I wanted to have a start in red. ;-)

Also drive rods! I have never seen a

I think there are other parts you could use: pneumatik tube, Flex-Stuff from the
90ies LEGO® technic, and other parts - Just be creative!
I wanted this design to consist out of as few new molds as possible. Therefor I
would even prefer moulded counterweights now.

I dont see a problem with a third-party product if the quality is good. I can
definitely forsee having to explain to *everyone* who looks at our train layout
that these wheels are NOT a Lego product. But, I could live with that -
especially if those people could buy them easily. (Bricklink store, perhaps?)

I like these criteria, and since were talking about a MOLD not a part, color is
irrelevant, it can be molded in grey or black or red or whatever... I can live
with red as the first color run as long as we know another color is coming
behind it.

Ben, One thing that would be really nice that LEGO also doesnt provide is a
way to pick up track power other than the motor wheels. Now that would be a
tricky proposition with the design you came up with. How about a wheel truck
similar to the standard 9V wheels, with optional click-on suspension-looking
faring, but with metal flanges, and a standard 9V connector on top?????
(Just kidding but it would be nice....)

Hi Rosco!
Empty out a new motor (25$) or a defected one (<10$) and you have your power

I would prefer that LEGO do this. But if LEGO wont do it, then yes I would go
third party.
As some of you know, there has been some amazing molding done by Jeff (Little
Armory) Byrd to fill unmet needs in the castle and space areas, and Jeff DID
come to BF DC in August, and did ask trainheads what was wanted and I spent some
time on drivers and rod geometry (Ondrew was in on the discussion too IIRC) and
other stuff.
- See also LA Question where Brad is asked about Little Armory
- See the LA site to see examples of Jeffs fine work... its pretty amazing (warning, catalog requires flash)
Youve done some great research for LEGO, Jeff, or whoever chooses to take up
the gauntlet... I hope he gives you a shout as this is well within his
capabilities, IMHO.
Oh, and put me down for 2 dozen each in black AND red... gonna show those
eurotrashers how to build steam engines, yes I am.

I have it on good information that a third party supplier will soon be sending
out a set of custom drive wheels meeting many of these criteria to a select
group of AFOL train builders for evaluation.

True, or get somebody with (CNC) lathe access to do this :D
I'd prefer a wheel with counterweight. It might even help protect the part
against distortion, since due to the spokes the part might otherwise be somewhat
fragile.

Let me know when you start taking pre-orders. I wouldn't mind a few dozen , both
in red and black. Although red would make the problem of TLC not doing any red
wheels even more pressing :D
Overall the design looks solid, although I would have liked to see a simple
solution to the rods problem. I think, with one simple single mold, this could
easily be combined?

Hmmm,
Any chance that one could coerce you to mention to your good informer that
someone (ahem) would love to find his name (ahem) among said group?
Seriously ... Id love to have the opportunity to play with a couple of these.
Drive wheels are fun to try and design in a custom fashion, but it would be nice
to have them work the first try for once!

All right, Im willing to risk some ridicule for not knowing this. What is the
purpose of the counterweight? Is it to balance the load of the drive rod, so
that the wheel never has to lift and weight, per se?
What is the weight like? A small metal-filled LEGO piece?
Is that something that is typically done in real trains? How about model
trains? And have people successfully implemented it in LEGO trains?
Has there been previous conversation here on .trains that Ive misse concerning

Counterweights were used on real steam engines to compensate the weight of the
connection to the rod, so that the wheel would be in balance again. Without, or
with incorrect counterweight, at higher speeds there would be a significant
distortion in the balance of the wheel, causing it to put huge forces on the
track and make it run very rough causing much wear on track, wheels and frame.
Think about your cars wheels, they need to balance them (put some lead on the
rim at certain points) to make sure there are no uneven centrifugal forces on
the wheel. You cant drive at higher speeds without those either, same
principle.
For LEGO trains, it would only be decorative ofcourse :D

-some more comments-
Not all locos got it right- the AAR formula used for a period of time to devise
counterweight weight was out to lunch- IIRC, the Florida East Coast
suffered this badly with some 4-8-4s.
Counterweighting and ballancing are a tremendous comprimise in full size.
Basically, you can have a loco ballanced for a specific speed, or for 0 speed,
or kind of a average, and they tend to ride rough regardless- remember, you are
talking of forces in excess of 150 000 lb on a average north american 4-8-4 from
piston thrust, and a corrisponding vertical element (particularly if the
cylinders are sloped, at even as little as 2-3% off vertical...a typical UK way
around things...). More cylinders eases things out- a 3 or 4 (or more, but not
common except on gear drive) cylindered loco has much less ballance problems
than a 2 cylindered engine.
Under the wrong conditions, hammer blow can cause the loco to literally fly off
the track. This was the case in at least one UK rail accident (Southern Baltic
tank). It is understandable that this is less than desireable :)
As pointed out, they are basically decerative in Lego (or even up to 1.5/1.6
models), because forces are much smaller in relation to the engines...so,
ballance is far less critical (its a 4th or 5th power (not sure) relationship
for sure)

This is something i have spent hours working out (in my mind) as I walk the dog
every night! My conclusions end up lookin pretty much the same as yours
|
Here comes the wishlist to make up a draft for a new driver wheel:
1.) technic axle center
|
Yes
|
2.) peg hole for connecting rods
|
yes
|
3.) diameter bigger than set 7750 and smaller than set 396
|
How did you reach this?
|
4.) flange design similar to 9V wheels
|
yes
|
5.) narrow gaps between two wheels
|
do you mean the gap between two flanges of adjacent wheels, if so yes
|
6.) distance between centers of two neighbour wheels in a common dimension
(4 stud / 5 stud / 6 stud?)
|
yes
|
7.) running diameter dimension fitting to 9V and 12V wheel diameters
|
yes
|
8.) wheel thickness higher than 9V and less than 1 stud (avoid contact
between moving rods and wheel)
|
so the thickest bit is the pin connector hole?
|
9.) counterweight as click-on extra part, (if 2 moulds were possible)
|
Would be nice but by no means essential,
|
10.) shape not 100% after real prototypes but kind of legoish.
|
a generic wheel is best
|
11.) center stud with Legologo
|
not at all essential (imho)
|
12.) ((Extra wish -Additionally a wheel without flange (blind driver) should
be available.))
|
perhap the wheel and the flange could be seperate mouldings.
e.g the wheel piece looks fairly similar to the existing large spoke wheel that
people use with the addition of axle and pin holes and no groove arround the
circuference and the flange piece be a pretty simple ring shaped piece with a
click fit onto the wheel
|
Question:
If only one single mould would be possible due to too low demand and high
costs for new moulds, what would you prefer: Should the counterweight be
included in that wheel-mould or not? In case of only one mould being
possible, the users would surely obmit in blind drivers (since anybody could
easiely cut the flange off himself - better have a wheel with flanges than
not having it....).
|
I have also been thinking more complicated than this for electricity pickup
using a metal flange etc but I think simplicity is the key if we are going to
get anyone to make it. This is the one piece that I would be prepared to go
non-lego for

Ben - I may have missed something. What did Brad say no to? Moulding this
specific part, or big drivers in general?
I really like the look of this part, and everyone knows we all want drivers, but
I think the spokes seem a bit thin and may weaken with heavy running -
particularly around the coupling rod mount.
Personally, I prefer a smaller wheel (3 studs across the hub). What size is
this across the hub, rather than the flange?
Its just if you use a flexing wheelbase, the drivers have to pass freely under
the sole-plate, so I find smaller than scale to be more useful. Mind you, Id
still use these, and I appreciate that if its going to be a single mould, it
should be a compromise between the requirements of 6-wide and 8-wide modellers.

On the left hand is a wheel from 396 etc. And I never saw a broken one. My
spokes are twice as thick as these old one have been.
|
Personally, I prefer a smaller wheel (3 studs across the hub). What size is
this across the hub, rather than the flange?
|
Have not measured it myself (in millimeters) so far, only in
CAD-coordinates...
|
From your own picture, eyeballing the measurement by holding pencils up to the
wheel and the ties below it and so forth, I get that the hub diameter is just a
smidgeon below 4 studs across, while Jason of the green engine wants 3, which
coincidentally is about the diameter of the wheel you show next to it (the one
used in the 7750?).
Given that wheel exists, why do another one that diameter (ignoring for the
moment what the price of that wheel actually IS) ??
That said, though, I think for freight locos Id rather err a bit smaller too, I
guess. I have never seen a graph of engine population density vs driver diameter
so Im guessing but I think smaller may be a bit more common than say 5 or 6
studs across ala the Thatcher Perkins driver you show on the other side. But I
dont see 4 as totally too large by any means. In fact I think its a good
choice.

Im coming to the same conclusion, I was originally envisaging a bit larger. But
the large size of the flanges makes the dimensions you have to take into account
for footplate height much larger than on a scale model. The size ben has
chosen would give the most possible applications.

Given 5 bricks=6 ft (a minifig), then 5 bricks is if anything, midrange.
engines I have data on here- 8P (DoG) was 74, a UP FEF was 80, J is 70,
German 05 is 90, NYC J3A 79, GWR Castle 80, German P8 69
So, a 5 stud diameter looks about right to me.

Well the only 3 reasons I can think are:
1. Mounts on a Technic axle
2. has hole to attach connecting rod
3. has optional counterweight
None of which I think the 7750 wheel has 8?)

How many of those are high speed passenger locos though? In terms of population
density, low speed freight locos were much more predominant and they had smaller
drivers.

Most of the above are passenger- DoG is a one off. But, the P8 was a bit more
than a make up- there were 3800 of them built. :). Also, when you look at the
UK, 9Fs have a 60 dia wheel, which is small for most mainline locos- and I am
assuming most people here dont model 0-4-0 tank engines with 30 wheels :)
Go stand next to any loco, and you will see what I mean- they tower over most
people quite nicely :). Even a CP 0-8-0 that I was near recently- the wheels
are not as tall as I am (6) but they are still quite close.

When we have the NCLTC layout on display we deal with this one all of the
time. Of course, to make matters worse and generate more questions, it
doesn't help that we run multi-car monorail trains and Cary Clark's twin
spirals are always prominnently featured in our layout!

Speak for yourself... :-)
The other thing this ignores is that a lot of steam trains (the Castle class
certainly) had the main drivers going up through a slot in the sole-plate.
Thats why they have wheel arches, and why British steam locomotive nameplates
are all curved, to fit the arch.
This is very hard to model in Lego, particularly if you want the wheelbase to
flex through corners. Thats why I prefer a smaller wheel, so that it can pass
underneath the body. I certainly wouldnt want to try with anything larger than
what Ben has proposed.

Hi Tim!
??You are asking why I demand this (bigger than set 7750 and smaller than set

inbetween is not only a compromise, but in my eyes the golden center.

5.) narrow gaps between two wheels

do you mean the gap between two flanges of adjacent wheels, if so yes

Yes, I meant that. Sorry for my bad use of language....
|
|
8.) wheel thickness higher than 9V and less than 1 stud (avoid contact
between moving rods and wheel)
|
so the thickest bit is the pin connector hole?
|
Not really, since this hole is shorter than 1 stud. (look at any technik brick
and you will recognise that the hole is shorter than the width of 1 stud).
|
|
9.) counterweight as click-on extra part, (if 2 moulds were possible)
|
Would be nice but by no means essential,
|
I agree in the meantime. The majority seems to prefer included counterweights.
|

10.) shape not 100% after real prototypes but kind of legoish.
|
a generic wheel is best
|
What is your definition of a generic wheel?
|
|
11.) center stud with Legologo
|
not at all essential (imho)

But it would be really nice in case the wheel is from a third party: it gives a
more legoish feeling and increases the acceptance(imho).
|
|
12.) ((Extra wish -Additionally a wheel without flange (blind driver) should
be available.))
|
perhap the wheel and the flange could be seperate mouldings.
e.g the wheel piece looks fairly similar to the existing large spoke wheel
that people use with the addition of axle and pin holes and no groove arround
the circuference and the flange piece be a pretty simple ring shaped piece
with a click fit onto the wheel
|
Hard to realize this for 1 running diameter. And you need 2 moulds in both cases
anyway.

A third party wheel CLEARLY could NOT have the LEGO logo on it... so your
solution of sizing an opening to let the user insert a 1x1 round plate (and thus
having the logo on there if they wish) is absolutely brilliant. It ALSO leaves
the door open to someone building an outside frame locomotive since the axle
hole allows the axle to pass all the way through.
The more I look at this design the more I find to like about it.

Id missed the fact that the cover could be a 1X1 round, that is a veryy good
idea. One of my misgivings with a cover was the fact of outside framed locos so
this would be best all round

Yes, I should have looked better at the images. The ring aroung the middle of
the pin (or where the middle of the pin would be if it was a full pin) moved the
coupling rod out away from the wheel.

I just meant not to try to copy any one real wheel too much as then it wouldnt
look so much like other wheels, Your wheel is what I mean by generic, you
havent tried to make it like the wheels on any one locomotive but rather a
generic mix of all locos. It also has the Lego look.

I dont think I explained it very well, Ill have to do some drawing to show it
better I think. However there would only be one complicated mould with the
spokes and axle hole etc and the other would be simple.

Good question! It arguably doesnt matter as much as some distances though,
unless you plan to mount something between them. In many applications you just
have the main rod and or connecting rod to deal with and the eccentricity they
have is only a factor in considering how much connecting rod and piston rod
throw youre going to have to deal with.
Still it would be nice to know. Personally I hope its rather short.

Well, I know how pointless it would be to argue with Lar (grin), but it
would seem silly to not have this be a standard distance. I could easily

Hi John,
thanks for bringing up this question! I was thinking about this for a while
myself and I decided to do it in a distance of 8 mm (which is same as two stud
centers next to each other on a 1x2 brick - or holes in a technick beam.)
You nearly could have guessed it out of the picture above, the inner black line
is the diameter of a 1x1 round plate (=8mm).

Ya I agree. I was only saying that in the universe of design decisions, some
matter more than others and this one matters less. But Bens design does indeed
use a standard distance...

I look for that reference a lot too. I find it this way, via a trick I learned a
while back, maybe it will help you too. The more link on the side of the post
box when posting in FTX mode leads you here:
http://www.lugnet.com/publish/ftx/guide/ftx-refcard-600x525.html
delete the html part so all you have left is this: (this is the key thing to
remember):
http://www.lugnet.com/publish/ftx/guide/
and thats your guide. Midway down the page is the info on inserting LDraw
parts, which takes you here
http://www.lugnet.com/publish/ftx/guide/ldrawparts
so the cam you want is
Hope that helps!
And oh by the way, I got my wish, Bens throw IS rather short, just one stud.
Some freight engines have higher eccentricity but I think short throw is a good
compromise.

Sorry,I have not had time to read all of the posts on this subject.
I would love to see TLC make these wheels. But, I dont think that they ever
will. SADLY ,the 12v era has gone. Even though 12v wheels still work fine on 9v
.rails.
Being this , was any AFOL planing to start making some new steam train wheels?
In RED,BLACK & GRAY. As I would like to get some . Im guessing that they wont
be cheap. As A mould would have to be made. Perfect design BEN !! Many thanks ,

Another few issues with clearances - I wonder if youve considered all these...
It looks to me as though if you did use a centre round plate, a coupling rod
would have a hard time clearing the stud. Not a problem to leave it off though.
Half-plate thickness lift-arms actually enclose the end of the dark-grey
half-pin and half of the ridge around its mid-section. Would they clear the rim
of the wheel if attached as a coupling rod?
The spacer ring on the inside of the wheel needs to be carefully designed so
that it doesnt sink in to a technic hole, causing the rear of the dark grey pin
to rub.
If you space the wheel out too much though, you couldnt use an ordinary technic
pin (or ball-type steering pin) and stay within an 8-wide loading gauge.

To answer your question, Yes. Based on some inside information, somebody is

Of course that means Id be paying $60 for enough of them to rebuild my
Challenger! :-)

To answer your question, Yes. Based on some inside information, somebody
is making train drive wheels. Ive heard they will be available for purchase
certainly before christmas.
It leaves me wondering, how much would you pay? What is a fair price?

well... something more than what I am getting parts for out of the 3033s I
bought on sale ( about 1.2 cents a piece) and something less than what I paid
for my last service pack of larger drivers. I cant find the number for it
offhand, service packs are hard to search for... but it has two pair and they;re
the larger drivers... it MIGHT be this one:
Nope, those are the smaller black spokers, these are the larger red ones... its
either this one
or this one
part 4180c04 is the part number I think but Peeron doesnt have a pic
These larger drivers are the ones ues in 7750:
The packs are hard to find, and I was happy to get the one I did... I paid 30
Euros for (and thought I got a pretty good deal on it) at LegoWorld from Henrys
Brickjewels...
(BTW the 7750 inventory is wrong, it omits these wheels of which I speak!
http://www.peeron.com/cgi-bin/invcgis/inv/sets/7750-1?withpics=no )
So, somewhere between 1.2 cents each and 10 euros or so.. Does that help?
OK more seriously these things cant be cheap, there are tooling costs to
recoup. The demand is probably inelastic up to a point at which point it turns
elastic. To see what I mean...
Id pay 5 to 10 a pair without even blinking but I bet that requires a huge
production run to recoup your costs so Id be resigned to paying somewhat more
than that I guess. Price them at 50 a pair and Id be thinking pretty hard about
how badly I wanted to build big electric locomotives (remember, these spoked
drivers would be good for large european electrics too!) and big steamers...
So you need to find the knee in the demand curve. Maybe price them really high
and lower the price over time till sales stop increasing?

Whatever, its only money. Ive already spent a bunch on other BrickLink
orders for parts, why not spend some more for wheels?

This seems a pretty reasonable price (from the market point of view, I dont
know about production costs) especially when compared to the price of the large
spoked wheel. On bricklink at the moment the cheapest is $4 for a pair and the
average is $7.30 and these are in limited quantities + only in red!

Its can only be an educated guess but further to this does anyone have an idea
of the quantities that would sell. While a lot of AFOLS seem to have an
unlimited budget many dont (like myself!) thus while I would like about 12
axles/24 wheels; I would probably only get 3-4 axles and maybe some more later,
this would not really be affected by the price. (3-4 axles could be pretty much
said to be a minimum order.)
How many train modelling AFOLs are there out there? Most do probably not
read/post here and sof course some wont be on the net at all.

Thats why youd need an extra pair of wheels to show people at train shows.
Have a business card (or a link on your website) to the Bricklink store where
??? is selling them. Make it simple for people to get these, and I think theyd
become quite popular.
And it just came to me that a wheel like this would look great on my keychain.
Yea, Im a geek... :-)

All good ideas! Heck, GREAT ideas. The keychain ones could be the ones that got
rejected for being poorly formed or out of round or whatever...
Pardon me while I dip into fantasy mode... Suppose LEGO themselves got behind
third party efforts and put a link to the site of whoevers doing this... (and
to custom kit designers and to Little Armory and etc) Just a bare link with a
disclaimer saying they had no responsibility. Would that be cool or what?
Never happen, but if you really want VOLUME (which drives costs down) there you
go... that would be the way!!!!

With such prices I'd only buy those I'd need right away, and certainly none
to stock "in case"
If OTOH it would be around $5 per pair, I'd easily buy 20-30 pairs, just to
make sure I don't run out. (Somewhere in my head I've got plans for a
German BR43 and BR50 class, as well as a Dutch 1000 series electric engine)

It's hard to tell what a "fair" price is, because I have no idea what the
tooling cost will be, nor how many of them can be realistically sold at
which price point.
I would like to buy three to six pairs of them, maybe more, but that depends
on price. At $10 a pair I would probably stay with tree pairs, when the
price is more like $5 a pair, I would certainly purchase more than six
pairs.
Don't know whether this is realistic or helpful ...

I don't think that the fair price for an item that can be produced in almost
unlimited quantity (and in fact will have to be produced in large quantity
to create return on investment) can reasonably be compared to the price for
a collector's item that is long out of production.
That is not to say, I wouldn't pay $10 per pair (as I posted before), but at
least in my case, the ROI would be higher with a significantly lower price.
Avaiability in multiple colors (black being my next favorite) will probably
also help with that matter ...
Greetings
Horst

I would buy 12 axels, in all three colours !! Red , Black & Gray.
Total 36 axels @ $10us each ??? = $360us ???
But, for me to spend that sort of money the design would have to be perfected.
So that they work perfectly on 9v & 12v rails. And the push rods run smooth.
What about a Blind Driver ??? Many thanks,Teunis.
