Title: Best epoxy resin for backing bows with fibreglass strips
Post by: Wooden1 on May 08, 2020, 01:24:30 am: Hi guys, just wondering, have any of you had any experience with backing bows with epoxy resin ? I recently seen a video with a bowyer using walnut for the main bow body, then used a strip of fibreglass for backing and then applied the epoxy resin with black pigment. It had a great finish and looked really strong. W have any of you had any experience with this and if so what epoxy resin is suitable to use ?

A few years ago there were a number of commercial bowyers that tried this and quickly realized it wasn't a viable option.

If your using pretty wood lams, it dries clearer, goes father by rolling it out as its starts thinner and it permiates the wood lam better. Just a better all round Lam Epoxy.

If you have not use it I highly recommend it.

very good point mullet.

just so I know for future reference.

Pat B says no FG talk, but mullet is ok with it. Are modern materiel discussions ok for around the campfire?
