So, I need big treads. About 400-500 studs long total, and about 8-studs wide.
Ive jury-rigged some prototype treads, and Im fairly happy with them, but Im
curious to see some other examples. Anyone know of any?
Heres what Ive got so far:
They actually spin pretty well. But theyre a little fragile when you apply too
much force. They also dont clutch to the wheels, so the wheels can
theoretically spin without turning the tread. Not a big deal since I dont plan
on trying to motorize it (Id need a hefty amount of motors), but would be nice.

Your picture links dont seem to work, which is a shame as Id be interested to
se how they work.

That's just because he forgot to put a space in front of '<' (FTX should
really enforce this!). Cutting out the essentials gives us:

which does work (at least for me).

Huh-- I never remember what the right format is for an image inside the link. I
just copied it off of someone else's post that showed up in FTX, and used that.
Worked on the preview, so I assumed it was right :) I'm guessing that it not
working is an issue with news and mail readers... Would be nice to have SMTP and
NNTP strip out FTX formatting when a post is marked as FTX. Some stuff is still
readable, but others kinda get kludged...

The URL's are configured for Lugnet's web view (news and mail readers probably
can't see them easily)-- they seem to work ok on the web interface at the moment
(unless you mean that my webserver was temporarily unavailable). For the FTX
impaired, you can try jumping over to the directory directly:

Ever thought of the old gears, like from
this set? I actually dont have any
but it seems a small one might work for what you are describing.
This is pretty cool Dave. Usually the big treads I see are modified conveyer
belt links. Cant wait to see what it goes to.

Huh! I hadn't thought of that, but those old links might work since they've got
studs on 'em. If only they were available in quantity (and for cheap!)

Yeah, most of what I see is conveyor links. Initially I was planning on using
about 1000-1500 links and doubling them up to 6-wide, but it didn't convey the
right size for the vehicle. Plus the little holes in each tread looked a bit too
... Legoish :)
As for what it's for, it's a BrikWars-scenario-inspired MOC that I'm hoping to
build. Maybe for this fall, I'm not sure exactly yet. It started out pretty
tiny, and quickly took great leaps and bounds in size. Right now it's slated to
be about 64x112 and have 4 sets of massive treads:

You can easily get eight wide tracks with the conveyor links, simply attach a
1x8 plate or tile across two lniks spaced appropriately.
The conveyor links are designed to accept 1xn plates where n is greater than
four.

I actually tried that, hoping that they'd stick well, but sadly the links seemed
to pop off pretty easily. We sorta had the same problem with NELUG's quarry
display, since the plates or bricks we stuck to the conveyor belts would keep
popping off.
I had hoped that having a double-wide conveyor would help. After all, there were
3 center posts connecting each link, and 6 all together, as opposed to the
quarry, where there were just 2 per link. But it still kept spitting off teeth
nonetheless. Not sure if it's because of the friction with the ground, or if
it's because the gaps between the links are tight enough so that they force the
plates off. Anyone had similar difficulties?

Actually, you can fit on 1x3 bricks or plates (or larger)-- the links fit
widthwise just BARELY within the walls of a 1x3. I was so psyched when I first
heard that (always wanting to attach stuff to conveyors), but I guess I never
had much luck.

They seem much less likely to pop off if you can get them to snap on
properly. And I really mean snap on, with an audible snapping sound. I've
had 1x3 plates (the smallest that will fit) on these tread links pretty much
stay there for a few hours. It almost sounds like there's a molding
tolerance issue with these tread links. It will be interesting to see how
well the links used in 7258 work.

The most success I found trying to cure the problem is once what appears to
be the centre of the link you're securing to snaps, you ought to be okay.
It's a really loud, audible, snapping sound.

It's a pity one can't fit on the 1x4 or larger bricks, when LEGO made the
molds for them they forgot to cap the strengthening bars at a level that
would allow the bricks to snap onto chain links, and indeed, onto regular
LEGO hollow studs. Maybe someone at LEGO can fix this.
Cheers ...

Yes.
These reduce the distance from the wheel surface, and with the addition of a
hinge brick top, can be effectively driven by a 24x43 wheel+tyre. Of course they
could also be easily reduced to a 2x8 footprint.

| | | | | | | | | | | | | | | That's some nice work. I have been looking for some way to make custom garage
door
Your design has inspired me to make some variations:
Design 1:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1102267
Variation of your design base on 3L lift arm and 3L stud-less beam. The chain
is strong but the large plate attachment is weak.
Design 2:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1102268
Improvment of design 1. Use 2x2 plate with pin hole or brick-with-pin for
stronger plate attachment. Best of all 4 designs, however...
Design 3:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1102269
Since I only a few 3L stud-less beam, I look for possible replacement.
Chained cross-blocks work fine, but use a lot 2L lift arm and is a little thick.
Design 4:
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1102270
Chained "nose" piece or 2L stud-less beams works OK, but the link tends to
wobble.
