Finger Calipers Build (full draw pg3)
« on: March 10, 2023, 01:25:21 pm »
I had a stave 61” long. Lots of twists and crocks. Thin rings nothing special about this one.

I roughed it out and put it on my caul and gave it a lot of heat correction and a heat treatment while I was at it.

Then I got it bending pretty decent in my vice.

Then I finished tillering using only my finger calipers.

They have a attachment that fits on my rasp

And they also separate from the rasp to quickly give me information about the thickness of my limbs.

Then I shaped the tips and made a string

Here’s first brace profile.

I don’t want to bend it anymore than brace right now. It really needs to reacclimatize a bit. I’m sure it is very dry yet.

Will see what it looks like at full draw in a couple days

New bibs???? Fancy pants BJ.

Looks good for a finger guess :) How much weight you think you have?

I wish I had finger calipers... maybe my bows would bend as nice as yours do.  It will be nice to see it once you have coached it to full draw.   :BB
Seems like common sense isn't very common any more...

Thanks Brad. I think I could have gotten it a little closer but the one limb has a slightly narrow spot.

Yes sir brand spanking new drummer boy. First time they got any Osage dust on them.

I think getting the bend close might be predictable and repeatable. I think the draw weight is going to vary depending on the wood.

This wasn’t a very fancy piece and part of the reason I wanted to try this.

I’m going to guess about 36@ 26” if it doesn’t break first. Lol

I really am curious what the full draw will look like and how many lbs it will be.

So far I have only bent it a little in the vice. Then finger tillered to finish. Then bent it enough to string it.

To be continued

Looks pretty darn good for finger calipers. Kind of the way I do it, but my calipers aren’t nearly as accurate as yours.

Bentstick this isn’t really how I normally tiller my bows. I do use my fingers constantly but I have never tillered one without confirming it on the tree along the way.

This wasn’t a primo stave and I just wanted to experiment

So far it looks pretty good.

Will be interesting to see how the full draw turns out

Arvin’s build by the numbers got me thinking

PS I know my fingers know what a finished bow feels like

If that is you just winging it then your fingers have a lot of experience behind them.  Looks darn good to me having just used finger calipers!  Nicely done sir.  I’m not quite there yet.  Sometimes I get lucky and mail it but not very often.  Hoping with more time on the fingers I’ll get there.  ;)

Bjrogg, once I get it to low brace, I go to the tree and start using Eric’s gizmo when I can. Many of my staves have had enough character that my eyes and fingers are the best options.
