Hi Madmodders  :borg:

Her's a little tool for you to asymalate

My machine has a M3 morse taper in the tail stock, the running centres you get for this size all seem to be big brutes far too big for the size of work I do, and it not always easy to get in, with a nice robust set up.



Whilst at Johns a few weeks ago I noticed he had a nice small one:- running centre that is. So asked him where he got it from "ho I made it out of a M3 blank and a small clockmaker type running centre" he said.  :proj:

So these are the bits I picked up from the Harrogate show: from the Arc Euro trade stand



The arbour was set up in the head stock held nice a secure with a draw bar, faced off and turned down to match the centre:-  it was made of some quite tuff stuff, Darren would just love turning it  :D



Then it was centre drilled and with a couple of pilot drills opened out to 9mm by 25mm deep.



Then with a nice little boring bar bored out to 10mm for a nice fit on the centre



Then it was secured with good old high strength loctite:- her it is with its big brother



And how it will look in use



Job done in about 2 hours but it will be a big help in the future

 :D  :)  :nrocks:

Nice one Stew,

That will really make the set up a lot more rigid, not having the tool sticking out so far.

Darren:
Nice..!!!

That big one's a brute init.... :bang:

Stilldrillin:
Oh, I DO like that one Stew!  :thumbup:

Something else to add to the list..... If I haven`t got enough already......  ::)


I`ve looked on the Arc website & can see the necessary MT2 blank.

Is the "CO Live Centre" the one I need?

But actually I lied. I used one from Axminster as Arc were out of stock.  :(
