I use a form with rubber band clamping and i seem to have a lot of problem with the riser block slipping. Lams and sideways slipping is usually not a problem. I want to use a thicker riser block that sticks out to the opposite side of the window. Rubber bands would slide it to the middle. So i'm thinking of using a index pin to keep everything in place. I would dry clamp everything to the form and drill a hole where the sight window would be and use a toothpick as a pin.
Opinions and ideas about this plan?
I've never tried it myself.
I know of one guy that does what sounds very similar when making all wood bows.
He uses toothpicks as a pin.
I drill two holes in the center of the handle where the leather grip will cover the holes. I space the holes about 2 inches apart to keep the lams from shifting side to side lengthwise. I insert a tooth pick in each hole.
i did the same, on my last glass bow- learnt it from the smart ol' bugger above.
also had a riser slip on me, used only one pin though, maybe next time i will use two!!
and my overlay goes over the hole-i drilled it right in the middle of the handle- so there was no chance of exposing anything when i shaped the handle,
made everything so easy!!
I did this for the first time on the hickory baked lemonwood bow I recently built and it worked great. I did it similar to how Roy does.
I will use pins when gluing up risers with lots of accents or a complicated design. I just drill them in places where overlays will cover later, or where they'll get cut out when shaping the riser. Works great.
Sweet! Nice to know, i'm on the right track!
I wasn't planning on using an overlay on the next build. But i have some leftover piece of black glass, so it will be unnoticeable.
Im tryin to figure how to best do that without drilling through the bamboo back... Since im not planning on wrapping with leather.... Wood to pretty.
a block of wood with a guide hole drilled through it- place it on the bamboo- drill a hole- not all the way thru- place it on the riser- drill as deep as you need.
so now the holes will line up- kinda like a mini binghams drilling jig!
the pin hole here is for a 4d nail ground to a long taper on both ends and waxed--passes trough glass and all lams and 3/8" into the riser-other end into the form---
