When the tillering goal is no set

(1/6) > >>

willie:
Zero set is the tillering goal. 

What do you look for during the tillering process to see if you are pushing the wood too hard?  Before the set happens.

Pat B:
Set early on in the tillering process.

Hamish:
I don't look for anything, to stop set during tillering, other than the basics(no weak spots, limbs bending equally, not stressing the stave over the intended draw weight).
All the work is done during the design and layout, to ensure there is enough wood, either by length, or width to minimise set. Add low moisture content, and possibly a heat treatment of the belly, and reflexing. Just make sure you stack the odds in your favor beforehand.

If you still get more set than you wanted, modify the design of the next one, until you achieve the results you want.

the basics surely are a priority.  Lets assume an experienced tillerer at work with good osage with a design that just asks too much for the wood.
Does anyone frequently unstring and monitor how fast the stave returns to straight?

Of course, if only there were a bigger supply of good osage staves waiting in the corner.

Length, width, thickness, and belly heat, and being familiar with the wood you are working with, and slow careful tillering. We all know that, but it is worth repeating.
