Really enjoy these sessions Brad. Always a few nuggets and some great info from all participants. Really enjoyed Ken's information on various resins etc. and making varnishes. My first few archtops were done with wood from Don Barnes (Grandpas Workshop was his website from which he sold wood all over the world) from Okotoks, Alberta who bought and processed logs from the BC West coast, mostly maple, Sitka, yellow cedar and WRC. He was a violin, viola and cello builder who also made mystical finishes like Ken. He passed a few years ago, so lost a great friend, mentor and supplier. He started processing archtop wood after I visited him around 2000 as he was unfamiliar with guitars, but it was obviously in his wheelhouse. Anyway, thanks again for putting these sessions on. Technology and communication is amazing these days.

Thanks as always, Brad. Like Darrel, I always get something out of these sessions. Like more debt. :D I ordered some Super Assilex and Super Buflex abrasive sheets today after the meeting. I appreciate the tip, and look forward to experimenting with them.

I will be interested to hear about your experience with it. I will write up a more detailed report in a new thread. Like I mentioned in the meet is that it’s required to level completely first before going to the flexible sheets. I learned that the hard way. For leveling you can use these:

Tolecut PSA 8-Cut Block Sanding Sheets, Yellow K-800, 191-1527, 25 Sheets https://a.co/d/6ELlw6V

Next step for me is machine sanding to level. Dang rheumatoid arthritis. :D

I had trouble trying to show you stuff with the camera on my laptop. I thought I'd give you a better shot of my new way of plate joining. I just tried it for the first time and it works well. I have always just used "triangular" pieces of wood going in opposite directions to create a clamping force (if that make sense). That always worked for me, but I thought I'd try this method. These are $12.99 Harbour Frieght bar clamps. https://www.harborfreight.com/hand-tool ... 60539.html
There are a number of posts on youtube that show ways to "strengthen" them by inserting work into the alluminum extrusion, but frankly that's not necessary for this application. I put some cork on the clamping surfaces with double-stick tape.

Thanks Steve, that plate joining process looks like a winner - time to dump my little triangles and go shopping for some clamps! (and some Super Assilex and Buflex)

Good meeting and some good information. Sorry I had to bail out a bit early but my connection kept crashing.

Hey Brad, here's the details on the air dryer

I've been using a similar setup for the past few years. It works really well for me--I started using it with archtop plates, but started using it on flattops too.

The plate joining method I use is similar. The clamps below are Bora edge clamps. A cool feature is that the heads swivel about 22 degrees which makes them really useful for top or back plate sets that aren't rectangular. Harbor Freight sells a version of these for $12.99 that also has the swivel heads.

Darned if I can find that clamp anywhere. I want to try out your setup!

I checked with Bora and they don't make edge clamps that have the swivel heads anymore. Harbor Freight does carry a line of edge clamps in various lengths that look like the same design as the Bora clamps I have and they are much less expensive. I don't know how the quality compares, but they would be worth checking out. Here's a link to a 24" clamp which is the size I use. https://www.harborfreight.com/24-inch-clamp-and-cut-edge-guide-66126.html

When I actually do the glue up of the plates, I clamp a length of 2x2 over the joint to keep the plates from popping up like what sdsollod and ballbajos showed they do above.

I think a combination of the plate clamping action of these clamps, plus some of the Band Joe's silicone bands I talked about a few Roundtables ago, would be a pretty cool setup. One of the reasons I like using the two bands on either side of the seam, instead of a single board over the seam, is so the seam gets enough air to dry faster. Just an idea. Thanks for sharing info on this way of clamping plates.
