I know that some of you guys may think that I am working with an inferior bow wood but I must say Hickory is very tough stuff, I got a 68" long stave to floor tillered and put a about 3" of reflex in it with some dry heat. I have always understood that hickory worked very well and I have some experience with bending Osage with dry heat. But this stuff does not work well with dry heat. I tried to put some reflex (recurve) into the tips and the belly broke across the grain after a very long time heating, even after heavily scorching. So the stave ended up a little over 64" long. I shorten the stiff handle to only 8 1/2" long. The width at the fades is 1 7/8" and the tips are about 1/2" wide. I tillered the bow to about 60# @ 26". I was looking for about 55 @ 28". I notice a bad hinge showing up about 6" from one of the tips. I had to cut the stave to 60", Still wanting at least 55# @ 28"again I added alittle reflex to the tips and added some tip reinforcement to the belly. At 60" the string angle was not what I would like. The bow seam to stack the last inch or so. After some carefull tillering and about 50 shots, the bow ended up with a little less than 1" of string follow 58# @ 27.5". This was my second try at hickory, the first was not dry enough and ended up kind sluggest. I need about 100 more shots through it before I can call it finished.
My question is: I live in a humidy area. I keep the bow dry and in a dry inviorment during the building/tillering stage. I want to shoot it in (2-300 shots) before I apply the final finish. Will shellach be Ok for now and then for the final finish a polyurthane?
