ERC as a core?
DavidV:
Not that I have any experience with these bows... But the grain doesn't look great on the ERC and you might not be getting enough pressure with inner tube. If the glue up DID go well, you may be able to blame the ERC for being oily.... although I've never had any problems gluing it.
toomanyknots:
Yes, none of the grain in the erc I have is anything near perfect. I am happy enough having a couple pieces with no knots. :)

TOOMANY,
Like I said on PP PLANET I think you should use a well cut quarter cut board, look for a board you would select as a unbacked board bow. Still bet Cascara would do well in this application, very similar in weight and characteristics. Sheer force on a reflexed ERC board is tearing the wood apart in my opinion. The wood is stepped through, and the sheer at the glue lines are doing their job, but the wood is failing. Think of a perry, and the stresses put on the glue lines in that design.

Thank you for the advice. I will definitely be on the lookout for some Cascara. ;D If I make another bow with a erc core, considering your advice, I will try to select the best board, and not go for reflex or a heavy weight this time.

Thats a big shame Toomany, I hope your next one is a real beaut.
