Small M2 Running Centre.
« on: May 21, 2009, 01:08:58 PM »

After admiring Stew`s handiwork, today I made a small running centre for my 7x20 Mini Lathe.....  :wave:

Whatever I`ve missed here, please refer to Stew`s posting........  :thumbup:


The centre & MT2 blank to suit my smaller tailstock.





Blank mounted in MT3 sleeve in headstock. Remembering to insert a piece of 10mm screw into the blank`s thread, for stripdown.
Roughing began....... At .010" per pass.....  ::)





A little hard at the taper end.





Found a nice new "10mm" reamer.





A little swarfe clearing problem. (No problem).





This is not a good time to realise you do not own a drift.......  :bang:





I then realised the reamer is a few microns undersize, so I polished the centre shank to a lovely "pop" fit.

This caused an airlock with the loctite...... Had to file a flat to allow the air out!

Just needs the taper shortening for the little tailstock, after the loctite has cured.





The centre is 23mm o/d, the tailstock ram is 22mm........ Now that`s close enough for me!  :thumbup:





Thanks Stew! Yer a gem......  :headbang:

Nicely done David

It makes a lovely neat centre, I see you ran up against some tuff stuff as well when turning blank down, its not to bad but it does make the old machine groan.

Cheers

Not worth messing about for a quid.

Those screw in tangs are great John.

I bought a handful of them when I modded my tailstock. They are worth it at double the price.
