Tillering problem

(1/2) > >>

 Hi Folks
I am in the process of tryiing to make a 70" elm longbow at 70lb draw weight.. It hs a D section, with a flat back and rounded belly, and 3" of natual reflex.
 I have got it to floor tiller and moved on to a long string on the tillering stick, However, the bow seems to want to flip round in the hand or on the stick on even the slightest pull ( So thet the bow is in reverse!)

I cant really fathom out why this is happening

Any thoughts or help would be most appreciated.

Keith,
I've had something similar happen to me when I forced a bow into too much reflex and made the profile a bit too thin.  She kept sliding around the handle and ended up with the string across the back.  That happened to me on a 45ish bow with about 4inches of reflex and about 1in at the handle.  It liked to do it when I took the stringer off after bracing though.  What are the dimensions of your bow?

That's normal(and annoying) with reflexed staves. I have had to get a helper to hold the handle area to keep it from flipping around until I get it bent far enough to stay put. One other thing to watch for is it is easy to miss weight with a fairly reflexed stave and make it too light.........so just a heads up there........you may know this already.
Best luck,
Darcy :)

 Many thanks guys..... So I'm not doing aything wrong then ?   I hope that working past this stage might cure the problem?

By the way the bow is just under 1 1/4 " wide at the handle and 7/8ths deep and i got it tapering down to 1/2" x 5/8ths at the tips, which I want to be narrow and slightly deeper , before I put any bend at all into it

The reflex is just under 4" at the moment when I checked it properly

Should I try to reduce this reflex?

If you feel you have the bend straithening out evenly I would go straight for brace height. Once at brace height of 5 to 6 inches it should stop  trying to flip. Work slow and concentrate in getting the shape you want close to brace height, don't pull it too far, work up in small increments and it should be fine. A little set will work in to reduce the reflex and all will be OK.
Good luck,
Mark
