Remember this?
Well, it's been planed and sanded and joined and now it looks like a back
The back is glued to the sides and held with blue painter's tape
Blue tape has better stretch so it pulls the joint together better.
It also doesn't pull up splinters when you remove it.
The wood looks a little grey right now. When you cut or sand purpleheart it turns grey.
After it's exposed to oxygen and UV light for a few days it darkens up and turns purple again.
The bookmatching is perfect and the glue seam is really tight.
Can you see the glue joint? It's nearly invisible.
The box goes into the Go-Bar deck so I can clamp down the braces and put more
pressure on the glue joint.
I'll show you what a Go-Bar deck is a bit later.
I use what's left over from cutting out the back to make some joint supports.
You'll notice that these pieces are cut with the grain going sideways.
They'll be glued to the inside of the box to strengthen the glue joint
of the back.
This is something the customer will never see, but it makes a stronger, better instrument.
The box goes back in the Go-Bar deck and I clamp down the center seam supports.
And here's the Go-Bar deck. The yellow fiberglass sticks are wedged between the top
of the deck and whatever I need to clamp. Using this device I can clamp things where
a traditional clamp could never reach.
