Hello people,
So, I'm building a Kennym takedown. I built the form and glued up my first limb. When I removed it, I noticed that I have a radius on the belly where it should be flat to sit on the pads. The back in the same area is perfectly flat??? Not sure how this can even hsppen. I used a pressure strip, pumped the hose to 55psi. The form is flat where it should be, hence the flat on the limb.
Any thoughts as to what might be going on here? I could use some opinions.
Thanks.

Looks like the wedge is upside down. The long flat side of the wedge should be on the belly side of the limb.

I would agree with wedge being reversed. I have done the very same thing a time or two, well maybe even three times. LOL

You might be able to glue a mini wedge onto the limb and make it work okay. I was able to pull it off, a pain but nothing to lose.

I see.
So, when you cut the angle is the cut side supposed to face the back or the belly?

Lol...I actually scribed the radius onto the limb pad and sanded it out. It sits perfectly. I glued both wedges in upside down so at least the angle will match...oh man.

you can use a 'reverse' wedge if you design for it. My recurves are this way but the flat part of the wedge needs to be as long as the riser pad so it sits flat.

Well, this is why I didn't put too much into making the riser pretty. Of course...the riser isn't the problem here but, hey.
So the next time I cut wedges, I will mark the cut side as belly.
Does Kenny sell limb hardware...bezel, inserts, etc?

Great recovery!

Looks good now. Being you got the accent running into the limb pad you might want to cap it with glass. Just to be safe.

breazyears · « **Reply #14 on:** May 21, 2019, 03:53:31 PM »

That's an idea. I have other issues lol. The tiller is way off. If I measure from the tip of the wedge to the string, there is a .800" difference. I made the "stronger limb a little thinner to get it to that, it was an inch prior.
The bow is already light at 38lbs. I really dont want to take more off. I'm sot sure that's the problem anyway. I'm wondering if the pad angle has changed a little, and if that would cause it. Not sure how I should approach this issue??? Guess one way is to build another and make sure I glue the wedge in properly.
Any thoughts? I will try and get a pic up soon.

Pretty easy to see the one limb is bending more. Probably can get it right but will loose some weight.

breazyears · « **Reply #17 on:** May 21, 2019, 06:05:29 PM »

Ya, so you figure the one limb is weaker? I would have thought they were pretty dam close.

Bvas · « **Reply #18 on:** May 21, 2019, 06:19:35 PM »

You should be able to to get an idea if the pad angle is off with the bow unstrung.

Crooked Stic · « **Reply #19 on:** May 21, 2019, 07:44:03 PM »

Did you grind your own lams. Are you sure they were right. The way to check if the pads are in sink with each other is lay a straight edge on each pad and they should meet over center of the riser even not one higher or lower than the other. Are both string grooves the same distance from center -----------
