[Files] Home built Sound board panel press

   Belly heads
   With ideas and help from Terry Farrell ( Thanks you Terry) I  
finally got my soundboard & pinblock panel press /jig set up.  It  
works quite slick. The bottom cauls are all the same height which acts  
as a flat deck. The top & bottom  cauls are lined with a polycarbonate  
material so the glue/wood doesn't stick to it. The end pieces are 3/4  
inch brass with a 5/16 this bolt thru them..  Though still in the  
prototype mode I was able to press up a very decent Steinway B panel  
with some nice Sitka. (By the way I'm only doing this for my self so  
please continue to get your panels from Terry Farrel)
   After the planks are glued the top cauls are put on. The bolts in  
the brass end pieces apply joint pressures. Then 5 of my fire hose  
clamps go over the top to press the planks downward &  flat... to the  
bottom cauls.  This insures the panels turn out quite flat & afterward  
with modest planing and sanding it seems as though a good rib to panel  
joint will be had.


ON the other end I added press blocks around each piece of brass to  
distribute the pressure.
