To answer all your questions, it is a long story but all I can say is I`m not short of trying!

AdeV - I`m using tipped parting tools - although I`ve had ZERO luck with them! I have had some luck and got my best results with HSS ground on ally. I got my tipped tools to work once on the Stuart I`m building cutting cast. I certainly can`t just "pop my parting tool in and part off" - no chance! It has worked about twice and when it does work it just strips metal effortlessly!

Stilldrillin, thanks for the suggestion but sadly have tried that. Even been to the extremes with just a few mm overhang ...still doesn`t go.

Kwackers - yep, snapped the pigging tip, it just chipped on the cutting surface. £25 for I bet seriously, 20 seconds of use, if that. I can`t get in touch with the bloody people from the stand nor can I remember the name of the stand I got it off. Anyone else at the Midlands show remember the man and woman selling tooling, up near the British Horology stand?

An update on the brass puzzle MK2 :

I posted in Sept 2009 after returning from the scrap heap with this:

It was a 6 foot length of 38mm square bar. I chopped it into 3 x 2' lenghts just to allow me to store it. Finally thought this project was worthy of using a slither or two so I hacked off a couple of inch from one end.

Held it in the four jaw chuck and turned it round! I was expecting some hastle here which is why I`ve never really used it. With my round profiling tool it was like cutting butter:

Then drilled it with my big 15/16" drill:

Reground my internal grooving tool, :D

And started the groove:

Then used my nice new birthday prezzy from my wife (notice the make!!) to hold in my mill while I cut the top circle.

So from a block of brass to a puzzle bottom cylinder!

Next onto the interesting bit, my new idea for the centre shield!

They do indeed look the business.
But it seems the Japs are outsourcing too. "Made in Brazil". :bugeye:

lol, did notice that as well!

They were purchased second hand off an old machinest who has sadly gone blind. I think he has had them a while as well although they look brand spanking new!
