I went out and did a couple of non-thumb things in the shop. Wait - there are no non-thumb things!

Rim is done (pre-thumb) - I ended up laminating a cherry strip to the linings because I thought it would look good - and I think it does. Rubbed a very thin coat of TO on the insides.
It all fits together and tomorrow is the gluing.

Dave, a parenthetical question, about the Dremel tool right angle attachment. Have you found other uses for it in addition to the sanding drum? I'm a little bit of a tool addict and I have a spare Dremel....

Thanks!

I will use it for a saw blade, like for cutting the wood masking the mortise channel.. I've only had the attachment for a couple of weeks.

Sp I made up a new top clamping caul, rigged up a system to elevate the work to accomodate the spring clamps and make the whole thing easy to turn, and like that. Maybe tomorrow some glue will actually be spread, seems like it has take a long time.

One shot showing the clamping arrangement - I have 30 clamps and they go on very quickly.

I put 3 of these tabs on the bottom of the backer board so that...
..I could rest the form on them and..
..glue on the top and..
..clamp that sucker.

Went well, plenty of squeeze-out, quickly enough that no problems with the TB setting up too soon.

So the TB bottle sez 30 minutes - good enough for me, though I might just add 8 hours as a little security. ;-)

Trimmed top overhang using dremel with base (some self-adhesive thin cork to protect the top) - yeah I managed to sneeze during the operation and put a ding on it - not a problem but dang.

After making sure the back would fit nicely, I spread the glue, placed the back in position and taped at head and tail, then taped the caul in place and clamped her up. Waited a few minutes then removed the squeeze out.

So I've never been that happy with the stewmac tool for using the dremel to cut overhang or channels - I mean it works, but because the bearing registers on the side, so close to the blade, that any sort of tipping, for just a second, can be disastere.

Looking at it, I thought that some replacement 2" 10-32 screws to replace the 1" stock screws might be an improvement, and it is, for me at least. The bearing registers well down on the side, it is easy to see, and gives better stability.

Keep in mind that I'm 172 years old, so every little improvement helps. ;-)


Edit - I'm not sure that it is that great an improvement. I would be if the stewmac bearing had a greater surface area to keep against the sides. What I did does make the visibility better, but the tipping perhaps more precarious.

Dave, sorry if I missed it earlier in the thread, but is the finish on the inside sides just esthetic? Or does it improve stability?

Nice work by the way
