Using the new stuff
Hi all,
Now, this will probably interest noone and is probably of no use at all to anyone but I thought I would show you anyway.
I got a diamond turning tool (Eccentric Engineering type) for Valentines day and thought I would give it a shot. Then I got my new microscope like every one else seems to have now and took a look at the surface finish. Thats the first photo.
Then I honed a radius on the end of the tool and took another cut which gave a much better surface finish. I again had a look in the microscope. Thats the second photo.
Third photo is the 7/8" Whit thread I cut with it after adjusting the angle on the grinding jig that came with the tool. The thread took just on 20 min including grinding the tool from scratch

Mike, do a search for a thread on diamond tooling, maybe a year ago?

Funny thing is, the finish is actually very good, despite the chatter.
I mean it looks smooth between the ridges.

Hi BT there is a half depth runout groove which I mistakenly machined to half depth. I always cut threads without a runout groove and just thought I would give it a shot. A lot of timing and years of practice and it sort of becomes easy to know when to wind the cross slide out. Originally Posted by Anorak Bob

One thing I didn't do Bryan is radius the end of the tool in true whitworth fashion but then, it was only a trial. Again, that's my story and I'm sticking to it lol. Originally Posted by Bryan

That's pretty cool, I'm interested in your microscope thingy. Do you have a pic of it and how it mounts to a lens?
I have a telescope thingy thats supposed to be good for full high definition recording but I haven't used it much.

I use a fiber optics torch and look at stuff but I need to make a mount for the camera lens.

Hi Phil,
Being someone not new to machining what do you think of your new tool? I hear a lot of people talking about them, but a lot are new to machining and cant grind HSS as yet, so they take this way as the easy way out.
I would be interest to hear what you think of it and it's performance over just grinding your own stick of HSS. I see there is talk about it being more rigid etc because it transfers the pressure down the length of the tool bit instead of across it, but have never used one myself. So in your opinion would it be worth buying for someone that can grind HSS, or is there not a lot of difference other than easy to grind with the jig?
Dave
