Hi everyone,

Quick question:

How do you machine, say... a headstock veneer?

Let's say I have a part that's 1/8inch thick and I want to do a 0.080 in pocket for some inlays... No vacuum available.

Aside double sided tape...any ideas?

Mind you that it's wood...if it was plastic I could glue it to a sacrificial plate, and then boil the whole thing to remove the small pieces...

You've eliminated the two best options. Either use vacuum or double-sided tape. I agree with Andy though. Tape is problematic.
The only other choice is using locators and clamping, but you have to clamp as close to the pocket as possible. Just get a vacuum pump and make a fixture.

You could make a full face clamp with the pocketed area cut out of it. You'd have to index it into the proper position with locating pins. That is assuming the pocketed area is not some large percentage of of the face.

Dan I think tape is the best
Get a long spatula to remove it
It's no problem if you're really careful.
And I just use the shelving board from Home Depot with the white melamine cover it's extremely flat takes tape very well

Sacrifice board, hide glue, newspaper, hide glue, part/part's...... use Clothes Iron or use Micro-wave on defrost to release.

Blessings,

Kevin

Thanks for your replies everyone.

Definitely vacuum is on my bucket list, but for a one-off part it's kind of overkill for me at the moment. I'm actually in the process of designing a few different vacuum fixtures for multiple applications.

I think i'm going to try two options... Ken's suggestion, and Kevin. Didn't thought about the shelving board, I have a few off cuts here :)

I also like the newspaper trick.

I'll post a couple of pics once I machine the part.

Thanks guys!
