I had some old FLOR grade rings sitting around for the past ten years and recently aquired a Sage 590LL blank. Well, instead of dropping $25.00 on a pre-formed grip I decided to builde one. Glued the rings together w/ Tightbond III on a 3/8" threaded shaft w/ washers and wing nuts for tension. After drying I then left it on the shaft and put it in my cordless drill and started sanding away. I did however, make a pattern from my GLX 6wt and went by that. Well, what do you think? I was very apprehensive because I didn't have all the fancy equipment but rather basic power tools but I think it worked out very well.
