Q: how to secure tiller string

[lleroy]

Anyone know of a good way to secure a tillering string without temporary nocks?
I've improvised a bit, but I have had the string break loose several times,
when working on the bow with a low brace...

A temrorary nock, or a second nock for a stringer (only needed on one end, with a deep er groove at the other end) takes very little time or wood, I've cut stringer grooves1/16" from the end straight into the back of the bow (Yew warbow, no problem). Or filing a slight flat and a temporary overlay is also no problem as it will get removed when the final nock is fitted.
It's easy to save 5 minutes work by messing about for half an hour with a shortcut!

PS, in the early stages of tillering you want to leave a little extra wood on the tip to allow for string line adjustment etc... so there should be enough spare wood to file in a couple of grooves.

I leave the tips wide and use temporary nocks that are removed with final tip shaping.

Back when I was making high poundage bows for other people that were too strong for me to string in the early stages  i would glue on temporary overlays on the limbs with a stringing groove so I could string them with a simple loop stringer. I would file the overlay off once I had the poundage down to where I could handle it. I only put a groove across the back and later used this groove at normal brace to mark where the string grooves wanted to be.

One day I thought; why not leave the overlay and make it look good complete with the stringing groove, so began my current bow tip designs.

What one needs most these days is the correct name for something... "Tillering boot" or "bow stringer"

Thanks. I'll look for one of those next time I hit the hardware store...

A word of caution, on a stringer with leather boots on either end (as opposed to a stringer with a boot on one end and a rubber block or leather loop on the other) sometimes if your nock grooves are too near the end it can be problematic as the boot can cover the grooves, thus making it dangerously necessary to push the boot further off the tip.
