Adding length

[Weylin]

that looks trustworthy to me, Bubby. Clearly the key is drastically extending the glue surface area. Looks pretty cool too.

Here are a few in varying distances from the tip.

While siyahs are usually v-spliced in a simple lap splice  like the  above overlays  will support a considerable extension if glued and wrapped.
 All the cheap horsebows out there have a lap  splice for the siyah.
 Tim Baker actually claims that extensions will hold up if not wrapped. There is even a picture in one of the  TBB showing this.

Thanks weylin, it's very trustworthy, I've run them several more inches with no problems

Thanks for the pictures, they all look great and provide inspiration !

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.
 

Oh, man, they are pretty bows, I like the subtlety... not over done. Clean lines.
Splicing on a couple of extra inches is no prob when done like that...

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.

Those look like they are spliced into quarter/rift sawn Ash is that correct?

This thread is a great example of people originally urging caution, and to follow "conventional wisdom" -- and then several examples popping up that show that the conventional wisdom doesn't necessarily capture the whole picture.

It's so awesome to me that even though this craft is thousands of years old, we're still finding out new things about it.

(For what it's worth, when I first read it my first thought was spliced siyahs as well. And those have been around for a long time. So in this case it's just kind of re-discovering what the ancients already knew.)

Nice tips,It has never been the issue of the string breaking them off to me,Like has been said not that much pressure on them anyway,it is hitting them on something when they are passed the bow wood that will cause the problem,the leverage you get when they are beyond is high and since I am pretty rough on stuff I don't go passed the bow wood with my tips. But they sure are pretty I will admit.

If done poorly, they can be dangerous I guess?  But, so can a regular bow.  Just make sure to get a good mating and good glue lines.

Bubby,When strung where does the string ride in relation to the end of the stave, in my mind as long as the downward force is still pretty centered over where the stave ends it'd work. Nice tips too!!
