Heat on limb

[Garman]

How much is too much heat for a bow limb and what r the potential breakdown if too much heat in an area?

Wood ?

Laminate, fiberglass over woods

Smoothon I think is 160 is when it starts to soften

Depends on the type of epoxy used. Most have a heat deflection temp thats much less than 200deg and could delaminate if flexed when warm. Curious why your concerned?

a bow I built earlier, one of the tip overlays broke in 1/2 and one piece fell off. I replaced yesterday, used smooth on and put a heat lamp on it. It got a little hot and darkened limb edge.

the Glue in limb is what will be damaged. I never put heat on overlays, if they come off no biggie, but if you overheat the bow itself that’s a bigger prob.

EA40 will set at 70 f in 24 hours. I tested on the bow I hunted with last two years, it never saw the oven... no probs with overlays or that bow . I do heat the other bows I make but not overlays.

Not sure what to tell you on this one without looking at it...

You probably toasted the finish a little. The epoxy should be ok after it cools down. I regularly have to remove epoxy from metal forms using a heat gun on super high and its hard to soften.

Thanks shoot until it gives out...not like I am not going to make another bow. Lol heck finishing another this week anyways
