Mini Lathe Toolpost.
« on: December 20, 2009, 04:32:45 AM »
The toolpost on my mini lathe has always been located too high & wide for any sort of rigidity.  ::)

It`s ok for the little fiddly diddly brass parts I normally make, but is useless when faced with a piece of steel....  :scratch:





Winding the compound back still has the tool outside the cross slide footprint.




It then gets in the way of the tailstock nut.




Very limited on diameter too.




But, when it grabbed & bent my new parting tool.  :bang:

Something had to be done!  :scratch:




Remove compound & fit steel block, to give largest available footprint on crosslide.





(Yes, it`s not quite square & in line..... This is a posed pic. )




New (cheap) toolpost brings the tool into the crosslide envelope.




And improves the capacity.




Just need to chop away what`s in the way....... When the weather lets me get back out there.  ::)



Lots of work/ tweaking to do. But I think this is the way to go.....  :thumbup:

I use the same QC toolpost on my 9*20...Although I had to pack it up to get it on centre..

What a difference from the oem unit!  :thumbup:

I managed to have a few little workshop sessions......

Cut away beneath the toolholder to allow some clearance.





Will round the corner sometime, if necessary.





I have a 1" piece of unknown steel. The old set up screamed & rattled at a 10thou pass.

This cut sweetly at 20 thou!

At 40thou, (a handwheel turn), it cut nicely, but the motor began stalling.




Even the normal, mundane jobs are now much sweeter.....  :thumbup:



Still got to tidy up........ Some 5/6" whit studding ordered for the lock screw.

All in all, a very worthwhile mod......  :D
