Boring tool holder

[joe d]

For my vertical single build, I need to bore the cylinders on my mill, as the cylinder casting is simply too far out of balance to try on my Taig lathe. This of course means that i need a boring tool holder for the mill. Since buying one would just be too easy, I decided to try my hand at building one from the plans posted a while back http://www.homemodelenginemachinist.com/index.php?topic=1288.msg9277#msg9277

Right off the top, I had to modify the plan to replace the shaft with a tapped hole to fit the spindle on my taig mill.

Continued.....

Since the adjusting screw is steel, and I elected to mill the body out of ali instead of steel as called out in the print, I decided to add some brass bushings

Turning bushing in three-jaw, with slight recess turned in the jaws to hold the workpiece

Loctite is my friend... stuck in place, bored, milled, and tool holder being test-fitted

all the bits ready for final assy

and here it is, ready to go!

I'll let you guys know how it works.....
