Hi Nevadablue: Aluminum on Aluminum, expect gaulding. I would use a steel thread. Carl.

Hi Gang: I was thinking about a printed tailstock and how to fit the left handed screw. What if you just tapped the whole tail stock M12x1? You could put a collar on the headstock end to stop the

Hello Rick: I really like it! And you can still bore it from the head stock. I might like to print one for use with the head stock riser block! Thanks, Carl.

I'm in your debt. Thankyou.

have a Unimat DB200 for sale. It is in working condition and has the power feed attachment. I have a number of accessories including the milling column and table, divider head, threading attachment w

lol I will forever refer to my 3d printers as "plastic poopers" from here on out

"not so confident on the various curved surfaces and what not" If you've got a 3D printer, use your plastic-pooping-robot to print yourself some radius gauges, that's what I did.? I've got a set of

Also if anyone felt it was truly a thing worth chasing, I'd bet it wouldn't be difficult to model around some off the shelf parts to make it a bit more functional without needing any of the original

Not sure if this would work but I modified the tailstock model to make it easier to print.? If printed in the orientation of the screenshot it shouldn't need any supports. Huge "I haven't even tested

Yes, teasing in a way, but ‘guide pin’ for something that looks like a spacer bushing?

Thanks SMJ for that model. I’m completely incompetent (at a lot of things) at CAD so what you made should make it possible for others to replace missing parts. I just ordered some aluminum stock to

I wish you had, looks like you did a great job on the U3 model lol.? Hopefully I'm up to the task.? I do a lot of modeling and reverse engineering at work.? I trust myself to get the important

I'm the one who made the U3 CAD models up on Grabcad. I thought some day I might get my hands on an older version and do the same, but that hasn't happened yet : ) I was using the free student version

Strange names??

I’m going to try this one: https://www.thingiverse.com/thing:6067712 It looks like a good possibility that it can work. All 3d printed except for fasteners I think.

Nevadablue: Did you also machine the dovetails?? I think you're going to have an adjustable gib on one side, but the layer lines may be an issue on the other side.? They may tend to "lock"

If you are looking for "free" 3D CAD you are kind of limited in your choices: 1) Fusion 360 has a "free" version but it's limited.? It is available free to hobbyists and can be used professionally on

HA! I found it. BricsCAD Shape, can be directly downloaded. That is what remains after the trial. I’ll just start with it. Link here: https://www.bricsys.com/en-us/bricscad-download

Keith, thanks for the tip on the Bricscad. I just sent them a note about the trial. It looks like (from their website) that it quits working after 30 days. I don’t want to learn it and then not have

I have read that PLA will creep or warp under continuous pressure. I haven’t experienced that yet, but I did make something that collapsed in the sun. A Black PLA mousetrap will die in the sun, LOL.
