I have a three piece 50#@27" 62"ntn with a 15" riser. the riser is cracked and I want to replace it with a riser made from poplar. Is poplar strong enough to use as a riser wood.

Not in my opinion.  There is so many other better choices out there.  If you did use the popular you'd have to laminate it with some other things I would think.  Chad

if you want a lighter wood you could use maple or ash.  poplar just ins't strong enough.

thanks guy's
