I have a nice ERC bow blank that's been setting around for some time. I put a few hours into shaping it, preparing to sinew back it only to find that it has warped in the narrowed handle section...enough that the string would likely fall outside of the handle AND enough that it drives me crazy.
I've tried the heatgun in an attempt to straighten it in the handle. Seems like I even tried steam (but it's been a while? such that I don't recall.)
Frankly I don't know what else to try.....
BTW, I've had trouble bending ERC heartwood in the past, once while trying to flip the tips, so it seems that it's at least difficult and perhaps impossible to bend......
