Gonna pick one up that needs a couple, OK, maybe all. Even be interested in borrowing one if you have it. Just needs to be flat (which I know, many are not).

Thanks

Can you make some fakes out of sheet? You could solder some wire around the edges to match the contour.

Dennis Holler If its old and broke, I like it

Dennis - thanks for the idea. I have a bunch of castings of other styles (4 wheel Blomberg, 6 wheel similar to the ED E units, in a flat aluminum cast style, but the originals have the feel of the prototype, so I'm kind of partial to those. Might have to see what the 3D printer can do if all else fails.

There is a need for these, but not sure if enough to justify a someone like Henning’s set up to make them. The 3D printing is a good option. I know I will need at least 4 someday. Mine have not broke yet, but will someday. They are bowed out about 1/4”. Just a matter of time.

I am looking for someone with a 3D printer to make a sample part. I have created an STL model of the part. It is a truck side frame for a standard gauge McCoy E2. I have attached a picture. The part is flat on the bottom and is about 6" x 1-1/2" x 1/2". The part is cosmetic and will be painted black and glued to a steel frame, The original parts are diecast and suffer from zink pest. There are quite a few E2's with this problem. Please contact me if you are interested.

The bad ones start to warp so badly that even operating the engines becomes questionable. We probably should work on caboose journals as well!

Many libraries now have 3D printers for patron use.  If there is a college nearby you'll find lots of students that can print things out for you.  There are design labs at the colleges that have 3D printers and I have found thast many students have their own printers as well.

Steve, do you know anybody local than can print the files though?

There is a new young guy at TTOS SP that does.

We found someone to print us a sample part that looks like once it is painted will be an acceptable replacement part. This person is not available to print more than just a sample part. So we just need to find someone to print multiple parts. Maybe it's time to purchase a 3D printer.

Dave, there is a young man at TTOS SP that can probably help. Jeff may be able to get you his contact info.

Wow, Guys

I also would need these for my Cascade. My Cascade has about an 1/4 inch bow.

I think 3D printing of temporary plastic replacements for a lot of deteriorated alloy parts is a good stop-gap.

Soon though, I think 3D metal printing will become affordable for us hobby types, much as 3D plastic printing is now.

"Nice try, Lao Che!"

So an old thread with a new solution. When I made the ask, there were no spares (they probably would have been warped to. So David Nissen sent the STL file (used for 3d printing), I recommended that he thicken it up a bit (easy in CAD), and an hour and 12 minutes later, a part. The NH loco was the basis for my need, I ended up modifying a GG1 3D model on my basket case Cascade (which had NO remaining side frames).
