Has anyone tried this to help strengthen riser ? It would simply be glass instead of a decorative wood strip... BUT... Im worried about issues...like it delaminating and was told it had been tried and people had it delaminate.... this was by someone who I highly respect and has built a LOT of bows

Without the over and underlays the riser is just under 1", very strong with the glass running tip to tip.
Yea...like mine now imagine another gordon glass thru middle as I show in drawing... btw..my riser is 1 inch as well, the wood..

What loads are you strengthening the riser against? Running an extra strip of fibreglass through the center of the riser stack isn't going to appreciably strengthen the riser area in terms of fore-aft bending. It will help with side to side bending but that isn't the major direction that the riser loads come from.

The belly glass is the one that makes it stronger, even a second layer on the back of the riser will make it stronger

Yes, I agree. It is the extra one in the middle that is doing very little. The ones that run off the back and belly are where all the strength is.

See pic.... blue line as on drawing be another piece of 05 Gordon glass
Can i ask why you are putting more glass in the riser ? Is it just for accents? Or added strength?
The reason i ask is often times the expansion and contraction of glass is different than the wood in different humidity climates. I've had issues with wood shrinkage sending bows to low humidity climates even though my moisture level was excellent, and have the glass stand tall and crack the finish. Same thing with phenolic accents. I always try and stay with wood accent lines myself....

The thought was for additional strength...however based on advice I have recieved... Im not going to try it
