Lathe Boring Bar Holder
My milling machine boring attachment finally arrived from China. 50mm so needed 12mm boring bars.
I have been one of those cowboys that clamp a round boring bar directly into my lathe tool post :headshake: :smash:
But looking at these nine beautifully ground boring bars I could not see myself damaging that shiny surface by clamping them directly in the tool post.
So I had to quickly fabricate a boring bar holder. I do not have a 4 jaw chuck but had to face off a 30 x 30mm bar and put a 12mm hole through the center. After some careful calculations it turned out that 2 5.5mm spacers under 2 of the lath jaws and the 3rd on one of the corners would center the block as close as dammit is to swearing.
Then I determined the height it needed to be on center to the chuck and welded a piece of 15 x 15 sq to its side.

Question to the purists out there... Should I slit it and move the screws so it rather clamps the bar then still pushing the caps onto the boring bar? :confused: :headscratch:
