Adding length
« on: June 30, 2014, 04:29:04 pm »
The osage shorty thread made me wonder -------------

If you use glued on tip overlays of horn or perhaps another hard wood could you add a bit of length to nock to nock length by cutting your string grooves a bit beyond the osage stave?  In other words, cutting your string grooves out on the overlays rather than in the stave itself.. Wonder if they'd hang on and if so would you still use the super glue as the adhesive of choice ? Maybe a 1/2'' on either end ??
Not worth the risk ?

I wouldn't even string it up if the bow was over twenty pounds ???

Might as well make them short, save some wood to keep warm.

That's how I do most of mine, have a peek at yours. I cut the grooves in right where the core ends. It allows me to make a 66" ntn bow with a 66" stave. Ive had ONE overlay issue ever. I used the wrong wood and it exploded, no other failures of any type.

I don't suggest cutting the groove in beyond the end of the bow, no.  Consider the forces at work with an overlay and it will make more sense as to why you can get away with it. Unless its too short and pulled too far the string is never pulling on a 90, its always pulling down and in on a healthy bow.

I do it quite a bit, altogether usually starts out about flush with the ends, if you make the overlays 6" long you'll have no problems, but I glue those longer overlays on with tb3 I can post a few pic,s when I get home

  I go along with Pearly, just not that much leverage involved even at 1/4" past the stave. Doing them just past flush I don't consider much of an issue at all.

I would think that even if the glue joint on an overlay was only 1 1/2" that you could get away with string grooves a bit beyond flush...

Thanks for the input..

And I'd like to see any pix if possible ---- just to see what is being done..

I've seen Chris's work up close and personal and it is impecable!

This bow has been an inspiration for me for a long time. Whenever I come across a suitable stave, I will try something similar.




It allows you to splice in tips, which can result in a bow of unlimited length.

The extended stave via siyah is the best trick you can do. I make them all the time. I remember when we walked Bert through the splicing process with the above bow.
 Here's a couple of four foot Elm staves extended out a foot or so.
