Need a base for your fancy torsion box CNC table? The rest of this thread is how this design came to be, if you scroll down you will see this unfold as I designed this in the forums. If this helps you out consider a little donation to keep these types of projects coming. CAD - Onshape …

[image] uklr4: OSB thickness as 12.4mm Now that’s an oddball size. Somebody might have measured that as a true dimensions (perhaps maximum vs. average) for whatever (possible higher moisture than standard) 15/32" OSB that they had on hand. You might want to measure the true dimensions of yo…

That is my measured dims. My big box store has 4 thicknesses. In those they vary 0.3mm or more. That part of the cad is parametric, you have to input your own dims.

[image] uklr4: Onshape shows Ah, I had read “Onshape shows” as if it was a built-in material. In any case, the dims make sense, and @uklr4 should measure their material as well.

[image] vicious1: There is this fancy full sized CNC sitting in my shop on saw horses. Is it weird that I’d like to know more about this situation? :grin: Did you have a portable setup? … maybe this is off topic? I’m thinking about the feasibility of a portable setup myself. [image]

I was pretty sure I did a some pictures of it, I know I did some instagram pics because at one time I lasered the entire surface.

So first the good news - I didn’t blow up an end mill yet and I have something that almost resembles a finished part, as long as you don’t look at the far end. I did quite a few test cuts at the other end of this sheet and then let the piece finish. The ends didn’t quite line up (you can see the unc…

[image] Jalich: In Onshape, I can’t change the thickness of the materials. For me, even when logged in it’s in read only mode so this is the “default” thickness. you should be able to copy it to make your own changes. [image] Jalich: I wasn’t brave enough to fully send it on the first cu…

Also try conventional instead of climb, or the other way.
