got it glued and cooked last night, got home from work and worked on it some..pulled off belly tape and snapped a couple of pics before I shaped limbs on the beltsander..used a 36 grit belt, man that 36 grit really eats glass faster than a 50 grit.. gonna be shooting this one next week sometime.pic is of same part of limb one in sun, the darker picture is in indirect sun ..I am shooting for 44 - 48 lbs @ 28" on this one. I am using my old "Modified" Binghams 58" recurve form Image Image

I like those limbs. Man that 36 grit scares me. If you sneeze wrong it will screw you up in a heartbeat. 40 is about as coarse as I use for anything.

Ya,I was suprised how fast the 36 grit ground down the glass.. I stopped 1/8" short of lines and put a 80 grit belt on and took it on down to the line. I filed some shallow string grooves in and got a string on it, 1/16" difference in tiller and 50 @ 28" on my scale, tips are 11/16 wide at string grooves, I should have time to work on it tomorrow night..

You know what I've been doing for quite some time now is razor knifing the tape and grinding to it, instead of just marking it.....it's a lot cleaner and the tape doesn't curl up on you. i do the same with 36 grit only i bring it to about 1/16th and finish with 60 or 80.

Where the 36 grit rules is shaping risers out of ebony or other really dense hardwoods. i got some 36 grit spindles for my spindle sander that work wonders. the only bad part is you gotta go over it again with 60 and 80 before trying to sand it out with 120/220. if ya don't you end up with serious sanding marks you don't see till you seal it. i'm getting to where i use a lot of rattle can poly when i'm shaping and sanding out risers. besides filling grain slots it shows and cross grain scratches or wiggles instantly.

Ya gotta love that shellac as a sanding sealer, i know i sure do....

but there are some warnings about using it as a base coat under certain products. Check it out bro... I think it may be polyurethane.

Cool looking bow there. :D

I tried using the shellac under Tbird once and it bubbled up on me. Did not make sence though both are lacquer based.
Anyhow that bow is looking good.
Most of the finishes we use can be thier own filler put on thick and sanded to the wood. Just a bitch to sand :(

I'm still using minwax Spar urethane in a shaker can for final finish. I used the Bullseye Shellac under the Spar urethane once and it worked really good. At some point I will be set up for Krystal, T-Bird or something better than the Spar.
