Went and picked up my drilling jig from the machine shop.

Nice B-Rad

How about a pictorial on how to use it? I have a Dowell It that seems straight enough, but getting consistent alignment is a booger.

How about a pictorial on how to use it? I have a Dowell It that seems straight enough, but getting consistent alignment is a booger.

It's pretty similar in design to crooked stick and crittergetters jigs. Only difference is mine is a two pin and one bolt design. That way doesn't matter which direction limbs or riser are facing.

Block is the same length as the limb pads and same thickness of material(1.70" for 1.75" material after initial sanding). Block will be bolted to the piece of granite, so riser and limbs can be clamped to it. I have two sets of drill guide inserts. One set for riser and one set for limbs.

Hope that helps. You'll have to wait til I get the rest of my material for more pics.

Here is the thing on these bows. They are wood. Unless you have a mill or CNC you are not going to get thickness perfect everytime, So you need that block mounted on a machined plate or the granite will work to by clamping it. To keep the same side down when drilling you need to be able to drill from each side of the block. This keeps one as straight as possible. Then if your thickness is not perfect all the uneveness is on one side. sand the other side parallel with the straight side. And there you have it and most times be good to go.

The block is bolted to the granite.

I went with the bolt centered between two pins so that I am always drilling thru the jig the same direction and don't have to flip the riser over.

You should have laid the drill jig on it side when you took this picture B-Rad

I got a whole stack of them. My FIL gave them to me. They are sink cutouts from a hotel remodel.

Do you clamp a backing board on the limbs to keep from splintering the glass on through holes?

That's what I intend to do. You pretty much have to with this design, or you would be putting the hold down clamps directly On the fiberglass.

But I will probably also put wood overlays on both the back and belly side of the limb pads prior to drilling.

Darn that centered bolt hole is a good idea. Wish I had thought of that long time ago

Looks good

How long is that going to be?

[Crooked Stic]

Awhile back I put some spalted sycamore veneers in a longbow limb. My guess is they had some moisture in them because the delamed. So had to make another set of limbs. scrap barrel stuff again. walnut/cherry and maple belly.

Yer gettin pretty scrappy lately Mike! 

Good looking bow too!

[Mad Max]

Lookin good stic
