I don't have a book to sell you g but I have one and use it so here are my
tips. I had a Sorby Corp. demonstrator show me how to do it himself about a
year ago. First of all, have you seen these instructions?....

http://www.robert-sorby.co.uk/thread...nstruction.htm

They're probably the same that came with the tools. I got mine at the
demonstration and didn't get any paper instructions. I wish they'd put out
a video but I don't know that you could get much out of it anyway.

Some of the tips given to me...

1) Slower is better. I prefer around 200 rpm. I can "feel" the threads
forming easier this way.

2) Harder is better. Hard woods with, especially, tight and interlocking
grains are best. French Boxwood (ie the plastic wood) is what the
demonstrator used and I've found nothing better. Of course, you can't make
everything out of that but it's fantastic to practice on.

3) Get the feel. Develop a rythm as you form the threads. Make several
small passes AFTER you make the initial somehwat heavy first pass. That
heavy first pass needs to be right on so that your next passes have
something to hold onto and guide them.

4) Make sure you have that relief at the back of the inside threads!

5) I don't like the tool support rest. Too many things going on at once
with that extra tool. I prefer to use just the lathe's toolrest for the
inside threads whenever possible.

6) My main problem is getting the male and female pieces (not the threads
really) sized correctly. Take very accurate measurements and then oversize
the male. You can always sand a bit and reform the threads if need be.

Other than that, the instructions on the website pretty much say it all. It
just takes practice practice practice like anything else. Also, if you can
find somebody who knows how to do it, it makes all the difference in the
world to have them hand-hold you. You'll have it down in 10 minutes.

Good luck,

- Andrew

Hi there,

I'd be greatful if someone could share some experience about these
threading tools with me.

I've been trying many times to make threads for lidded boxes without
success. The doc that comes with the tools does not say much really,
and there is probably something to do that I dont know, or I do wrong.

Thnx for yr help

Eric
