Little tiller critique and hand shock...
« on: June 04, 2015, 02:10:52 pm »
Have this bow almost where I want it. It shoots very well but has a bit of hand shock, I'm not sure if it's because of the knot in the upper limb or not. I intentionally left that area a tad stiff when tillering but wouldn't mind a second set of eyes on it. Top limb is on the right in the pictures...

The knot shouldn't effect it but the tips look too wide. That could be where the shock is coming from.

Not just the last 2" of tip, but narrow the last 8" of limb. Id suggest getting that knot area bending more. It will hold up fine.

Tiller looks good and I agree that the knot should be left slightly stiff. Looks like you did a good job.
Do narrow the last 6-8 inches or so as much as possible.
Also note  to see if he handle pressure is even as you draw and let down.

On your first profile picture you do have some fat wood in the last 6" of your tips.

If your tillering has the limbs slightly out of time, this could be the cause of your handshock.

  I think the handshock is comming from your right limb, bending just a tad too much out of the fade, overall I wouldn't imagine the shock to be too bad, the bow looks good.

+1 and limb timing is important, especially if you're working with highly asymmetrical limbs.

Might as well make them short, save some wood to keep warm.

Thanks guys. I did notice that the bottom top was a bit thick. I think the picture makes the top top look thicker than it is. I'll try reducing that then shooting it. Shoots really good aside from the jolt.

I would thin the tips as has been said and maybe thin the knot area a bit, I wouldn't want it to ben much in that area if it was mine. Looks good overall, maybe a little to much out of the right fad as Steve said, always have to be very careful with that, that is where they always want to bend first so I usually save the fads until the last few inches and then get them working a bit. :)

  Only 2 things cause hand shock. To heavy tips or one limbs finish's before the other.

  Lookes like your upper limb bends more right off the hadle. The lower limb looks good but it's really hard to tell from a pic.

  Your tips look a tad heavey. B

   I think a main contributor to long bow shock is when the entire limb is finishing at the same time instead of rolling out gently like a fishing pole.  A while back I had to do a bunch of bows so I used the gizmo tillering device and all the bows had handshock where my bows don't normally have any handshock. I blamed the tillering device. I tried the device again but this time I marked the bow when it was at about 3/4 draw and the handshock went away.
