Best belly lam for ERC?
« on: August 12, 2014, 09:29:50 pm »
One of my bows that was a possible trade bow candidate developed minor chrysalis in one limb only. It was near done and didn't show up til I hit full draw on tree. I am thinking I may put a belly lam on it since it is a clean piece of ERC with only one knot in 69" bow and that is in the stiff handle. It is all sapwood except for a bit in the handle.

What wood would be best for the belly on something like this? And where would you get it?

Thanks folks, Marco

Pic is of the belly (it has horn underlays)

OK, so the other pics don't show much but that is the general location and I can see that the grain looks a lttle drastic in it's taper right there. Like  took it down just a tad too much, which I did  :'(

Never used rawhide I imagine Others will chime in that have.  Isn't Maple to strong for the belly in this case. ???

Hard maple should be a good choice. Osage or yew might also. Ask on "Trading Post" about trading for some.

Doobs be dang sure your tiller is spot on before you add the lam, otherwise your only adding a band aid and they will resurface on your lam.

If you are going to do a belly laminate why not get a ERC heartwood board and do a laminate with that?

If you do add a belly lam, you should consider thinning the ERC down prior to the glue up. Adding a very thin lam to a practically finished bow is likely to double the draw weight. Re-tiller the bow down to maybe 25-30# while flattening the belly for proper glue preparation, and you should be able to glue down a 1/8" lam of wood, resulting in maybe a 60# bow with room for tiller corrections.

OK fellas,

That should get me near to what Darksoul is tellin me, thanks DS.
Great idea Grady, I think I will  ;)
