    Funny you mention that- i've started to do that but my reason was to try to minimise possible telegraphing of the hard edge of the linings - i thin my edges quite a lot.

    This is the type of roller i was thinking some used:

    I'm intrigued by that John, but I don't understand what you mean by "breaking the inside edges of the lining". Do you mean going into each kerf with the sandpaper and sanding back a bit or....???

    No. I meant the interior edge of the lining, opposite of the rib.

    Never used it, but it looks way too big for he job at hand. Plus, cleaning the roller after use looks time consuming. I just plop my brush into the coffee cup full of water that is part of my glue kit and forget about until next time.

    I've also seen vids of a classical guitar maker who lays down a bead of glue and then spreads it with a little foam dauber on a stick that sorta reminded me of cheese-on-a-toothpick horses doovers. It looked very sophisticated, just the sort of tool a snooty classical guitar maker would enjoy.

If you count the back and the top that is 44 clamping operations. Boring! Slow! Not fun!

    On the plus side it does a champion job of clamping the edge joins, but there is a level to my patience. Going to re-think this design. Ken posted his clamping method with a cam sort of thing going on. Much better and now I get why it is a good idea.

    Here we go.... please use a brush. I get very little or no squeeze out. If you hold the component to the light to inspect you have an even film of glue it shoudl be fine. But what do `I know? I'm British
