This evening I finally got round to trying out a uni chaser i bought from John Berkeley when he did a demonstration at my local club last autumn.
 
I`d been hoping to try my hand at chasing before, but had been struggling to get hold of some decent Box wood, John had said this was the best native wood to chase.
 
I finally got hold of some box recently & here is my first attempt.
 

I was quite happy with the threads & for a bit of fun i cut a hex in the top of the bolt & put flats on the female piece to make the nut.
 
 
Cheers.

Cheers lads.
 
I`m not sure on the tensile strength but i can tell you the bolt is 2 1/2" long X 3/4" diameter on the threaded part. The Nut is 1 3/8" across the flats.
 
It wasn`t as difficult as i`d expected it to be Derek, though i have now seen 3 demonstrators describing chasing. I was lucky enough to meet Richard Findley last summer & he was very instructive. I think the critical thing is lathe speed, i did mine a 350rpm & letting the chaser do the work.
 
John is excellent Dennis, i would recommend you take a pen & pad & make notes, i find doing that invaluable, as i forget so much by the time i get home to the lathe.
 
 
Cheers.

I've had to get ZEUS out as my memory is failing me, 3/4 BSF is 12 tpi and UNF is16 tpi, I do hope you have followed laid down standards Baz.

LOL.
 
I`m sat in the warm Bill, so i`m not going back in the shop, but i do remember the TPI printed on the chaser was 20, but what pattern i can`t remember.
 
>>this<< is the chaser in question.
 
 
 
Cheers.

Hello Baz, Thats a beauty. I like the way the threads go all the way to the top of the bolt. it is very difficult to achieve. Well done. Cheers Alan T.
