Well today I screwed up a little, not a disaster just a set back:
I started off this morning by finishing off the tenons for the neck joints, so they're ready to glue now.
After that I turned to the head stocks for the binding, my first attempt at 3 ply binding, ah so you can see this coming :roflmao: First job was to create a form to bend and glue the 3 x 0.5mm binding strips together, so that was made from some MDF with foam double sided tape as a gasket sort of thing to keep an even pressure while the glue set (acetone actually). Next I cut the binding strips to size and warmed them and clamped them up in the jig and warmed them again, then I loosened the clamps one at a time and with a syringe applied some acetone to the bindings which welds them together and tightened them up while making sure they were bedded down properly and left them to set for an hour before finally taking them out, so far so good.
I measured the thickness of the finished laminate and it was 1.48mm, ideal I thought and routed the rebate in the headstock at 1.5mm and thankfully only at 4.5mm deep for the 6.25 binding strip. Next bit was to clean the bottom edge of the laminated strips, I did this by glueing a piece of 150 grit sandpaper onto a strip of plywood and sanded the bottom of the strip on that before cleaning off the inner corners. Finally it was glueing time so I put the strip in place and got some masking tape to hold it in place vertically with a bit left on top to flip over to hold it horizontally. I applied some thin CA and flipped the tape over and made sure the strip was well in and properly fitted.
So far so good and all looked well, after another hour I removed the masking tape and started to scrape the tops of the strip, it looked great, next was the turn of the sides, ah now here it is: What was pretty much dead flush was now sticking out proud by a fair bit, well spherical objects! I scraped away to get it flush and the entire cream outer laminate was removed, I wasn't happy, I may even have sworn but I can't really remember if I did or not LOL. All I could do was remove the glued in bindings but as they were reasonably consistent at 0.5mm proud I used a 2mm rebate 5mm deep to remove the. I didn't have any more binding so that's now on order and fingers crossed will be here Friday so at least I can get it done by the weekend.
Well that's something learnt, at least it only cost a little time and money not the whole neck (s). I'm not 100% sure what exactly happened yet, I'll measure up on Friday morning when I'm back in the workshop but I suspect it was the process of glueing with CA that has caused some sort of swelling. I didn't photograph the damaged sides, I was too cross so I'll leave that to you're imagination but just think a very tidy looking black banding instead of cream
