Title: %@#$@#!!!! clamp slipped!
Post by: razorsharptokill on April 04, 2008, 02:44:00 PM

I cooked an BBO bow last night and let it sit over night. When I pulled it out of the box I noticed one of the bar clamps had slipped off. Now I have about 2 1/2" more of deflex in one limb than the other. Is it a lost cause?

Going to make for an interesting tiller for sure.

Worth a try.

This is a tri-lam bow. Center is hickory. I guess I could run it through the bandsaw and cut the osage and boo apart then sand the hickory off each lam and start again ...grrrrrrrrrr..

I was using bar clamps the get the lams bent and spring clamps to press the glue lines.

I just set it aside for now.

I'd go for the cut the hickory and recover the good parts.  LOL

I would get out a heat gun and try to match the limbs first before I cut anything.

Yeah but will it retain the same shape as the good limb? I thought about putting the bow back in the form and cooking the offending limb to the correct shape and the good limb a little less to equal them out a little.

Razor and all,

Could you take the temperature of your hot box as you used it to cure that bow, and then either fit another light bulb or use a heat gun to up that temperature by 15-20 degrees, and try to reset that limb?

Those with more experience may know if this may work, or is just a waste of time. My thinking is, that by raising the temp of the epoxy above its original cure temp, it may soften, and allow the lams to shift enough to "reset" the offending limb.

What say, bowyers?

After epoxy cures I don't think heat will change it any.

The heat gun it is then to the band saw if that doesn't work.

Good luck with the attempt, Razor

Let us know how it turns out.

Went ahead and salvaged the osage and now have a new piece of boo (from Wingnut) just about thin enough to re-try my BBO.

I sanded all the hickory that was left and the saw marks out. I used pencil to look for low spots or dips and have it pretty flat.

I'm thinking of using wire ties or 1" tie down straps as insurance for a slipping clamp
