Title: bingham risers
Post by: Jake Fr on January 31, 2012, 10:06:00 PM
So I am gonna make a recurve and A longbow an am just wondering if I took and made a longbow riser and cut it to the recuve angle it should still work wouldn't it and how will it be efected if the risers where shortend by say 3" will that change the degree of angle on the limb pad as well by it changing the degree of bend in the limb by shorting the riser

For a given stack thickness, if you shorten the length of the riser, and keep the same total length of the bow, you will lose poundage on the pull of the bow. You will lose 2 pounds or more for every inch that you shorten the riser.    John

Really just about anything will work
The question is how well it will work. A 12 degree pad angle is gonna be 12 degrees weather it's on a 15" riser or a 20" riser. Weather longbow limbs will work on a recurve riser depends on pad angle and limb desighn. If you put a set of  very mild r/ d longbow limbs on a riser with 20 degree pads  it will shoot an arrow but probably not very good.
You're gona need to put a lot of thought in desighn if you want to cross breed longbows and recurves.

I'm getting the impression that you want to use the same riser for the recurve and long bow limbs, is that correct?

If this is your first project, I'd advise you to decide on the Bingham (or other) designs that you want and to adhere to the material and design recommendations.  That way you will have a much better chance of ending up with two very nice bows.  

Experimentation is fun, but better to start off with a baseline of several successful bows.

No I want to make a low wrist grip like the long bow I think the recurve riser is way to bulky and a slimer riser like the long bow riser cut with recurve angle pads would work but want a 15 or 13" riser other than their 20" riser if that makes any sence

I once made a Bingham recurve riser shortned to 15" which made a 56" bow with the 60" limbs.  It shot well and was very well mannered. I don't see why you couldn't do the same.  the Bingham t/d recurve riser is very blocky and could be reduced with in reason and still be plenty strong.

Jess did you lose any poundage by doing that
