Title: Backing question
Post by: jflars on June 02, 2013, 11:17:00 PM
I'm new to bowmaking so bear with me. I worked up a red oak board and was trying for about 35 to 40 lbs but it turned to be about 25. I haven't backed it yet and was wondering what to do it with that might up the poundage. Is it possible to use formica and what would be the best choice of glue for that material?
I have a piece left over from a counter top I resurfaced. The bow is 68 long and 1 1/2 at the fades. I intended to hunt with it but have to get it to 35 lbs to be legal. If I can't I'll just use it for target and to practice form. I have a bum bow arm/shoulder so I can't manage more than 40.  
 I've taken a few deer with a compound so to get one with a bow I have crafted would be the
ultimate challenge, besides I'm not too fond of the wheels and pulleys, trads are much much prettier.

Back with wood and re-tiller.

A little goes a long way.

I would back it with a 1/8th thick piece of Hickory. Use Unibond 800 glue. I would induce some reflex when gluing it up.

You may want to trap the back a little with hickory on red oak, though. Hard maple might be a little more forgiving, as far as compression stress goes.

Start another to gain experience. Boards are inexpensive. Jawge

I agree with George. Start another one and concentrate more of each scrape so you don't over do it again.

Formica would not work.  I highly recommend you get and read Volume 1 of the Traditional Bowyer's Bible, particularly the chapter on design. It will really help in understanding the qualities needed for good bow material.  

It is very common to miss weight on your first few bows.  Backing them is a bandaid.  It can work but while you're learning, it is best just to start another bow.  Go back later and make your mistakes better.  But for now, you will learn more just moving on.

Don't expect your first few bows to be good enough, shoot well enough and last long enough to hunt with, especially with red oak.

At the risk of offending its devotees, the best thing about red oak as bow wood is that it is cheap and available.  But so was this girl back in high school.  And I didn't marry her  :)

Thanks everybody, appreciate the advice. I have a maple board to start another but just not sure if its hard maple. Is there anyway to tell like by making a dent. Anyway i'll put it away for now (red oak bow) and maybe fool with it later. It is kind of nice to shoot and very kind to my bad shoulder, it's probably a killer on chipmunks.

If you got the maple at the big box store its soft maple. I don't think they carry hard maple.
