Inverted Parting Tool.

[Stilldrillin]

I only turn small widgets, usually, and part off using a blade type 1.5mm wide tool.

I`ve seen the hint/ tip to part off in reverse, but not tried it until yesterday.......





It works a treat! 


My little lathe now laughs at large pieces of 1" brass. 





Like this "steam dome" for my boiler.





Another success!

Now I have my miller, I will make a 10mm square holder for the 1/4" tool shank..... 

Happy David.

David,

Yes it works great because the chips or swarf falls out of the cut.

Now for a bit of saftey. Be careful as the chuck can unscrew while cutting backwards like that.

Thanks for the note of caution Bernd. 

This chuck is flange mounted, not screw on......

How dumb can the Artful Bodger be?      I thought I needed to make a rear tool post to do inverted parting!:doh:

Thats a good idea my lathe will run in reverse and its got a flange mounted chuck I'll have to try it.

Thanks Dave

Not only parting but any cutting of brass helps if the tool is upside down.

That way the shower of shite goes down into the chip pan and not down your neck only to turn up in bed as sharp slivers.
