I really can’t comment on how to improve it, though, since I’m not familiar
with the LDD parts assortment. Or are you looking for comments on what to
change outside of LDD?
|
I think feedback on either would be helpful. I’m just starting up my parts
collection again as AFOL, so my part availability outside is almost as
limited as LDD. Any good recomendations though, and I could track it down in
one of the brick shops out there.

Well, I’m no train expert, I only started building train MOCs a little over a
year ago, but I’ll be happy to share my opinions. And the number one thing you
should do, in my opinion, is visit http://www.bigbenbricks.com/. Ben Fleskes,
a Lugnet member, sells custom LEGO-compatible steam engine wheels, among a few
other things, which I feel is a necessity when it comes to building steam
engines. If it weren’t for Ben’s wheels, I never would have gotten into trains.

The one area I had the most challenge was around allowing the front wheels to
pivot on curves, and keeping the piston/valve housing close on the side. I
tried out a lot of different things, but what I did was split the
Piston/valve assembly in two, with top curved part attached to the ‘engine’
and the bottom half attached to the trucks below to allow for rotation. It
may look like one peice in picture, but actually the middle piece of piston
housing is a 2x2 flat plate. I will still have to see if friction becomes an
issue in the reality of the build- Any different thoughts on how to handle
this challenge would be appreciated.

You’ve discovered one of the greatest challenges to all steam engine builders
everywhere - the pistons meeting pony trucks. I am a member of the camp that
isn’t satisfied without building a working piston into the design, so I’m forced
to fix the pistons to the drive wheels and getting the pony truck to negotiate
itself around them. I’ve seen your solution used a few times before, but I have
no experience on how it runs. I hope it runs well.
You’re welcome to check out my train designs if you wish. They all use Ben’s
custom wheels, though each one uses them a little differently.

If you’d like more advice on how the different methods of negotiating turns with
steam engines, or building steam engines in general, I suggest you view the
presentation Ben Beneke gave to Brickfest PDX this year. (I hope you don’t mind
me posting this, Ben)

Ben is an extremely gifted steam builder, so do yourself a favor and check out
his stuff, if you haven’t already:

I am doing some minor mods as well, extending the back a bit, as I work on
the tender.
The only other thing I am thinking of is using tubing instead of the two
‘sword’ peices along the boiler. That way could extend hand rail and curve
in front.
|
I would also suggest using some curved bricks on the roof of the cab. The
Dreyfuss Hudson design had a gently sloping curved roof that would be served
well by 1x3 curved slopes without studs (that’s what I’m using).
| |
| |
I, too, am working on this very streamlined steam engine (the Henry Dreyfuss
hudson), but I’m still waiting on parts, and only have a mockup built.
|
That was my original intention, making the Dreyfus, but I decided just to
call it a ‘streamlined’ since I diverged a bit and mixed some styles. Would
love to see some picks on how you handle the spherical dome on the front of
the boiler and the ‘fin’ down the middle. I thought about doing a fin down
the top with a place on side, but ended up going flat instead.
|
The work in progress pictures I have are horrendous, simply because I don’t have
the right color bricks for the design I’m working on (the right colors are on
order). They’re in my flickr account, but because I’m not proud enough to post
them to Lugnet, I’ll email you the link. I’ll let anyone else truly curious let
them find it on their own (not hard).

| Tony - Thanks for all the great info! (...) That will be #1 on my to-do list... Very nice. (...) I had been digging around the internet, but had not come across Ben's presentation yet. Very, very helpful and great building strategies. Awesome MOC's (...) (18 years ago, 20-Apr-07, to lugnet.trains, FTX)
