Cross Drilling Fixture from an AXA Boring Tool Holder!
i had an idea to make a cross drilling fixture for my shenwai 1236 lathes' AXA clone toolpost.
i machined the shaft from 3/8" 12L14 hex shaft and single point threaded the drill chuck end to 3/8-24 to accept an old but new Jacobs short 1/4" capacity chuck.

i left just enough of the hex so that i can put a 3/8" wrench on the spindle to remove the drillchuck
the shaft is supported by 2 mini bearings, one inboard, one out board.

the clamping action of the sleeve in the boring bar holder is sufficient to keep the shaft in place during the cross drilling operations.

an old 19.2 craftsman drill is powering the works.![Biggrin :grin: :grin:](/styles/default/xenforo/smilies/biggrin.gif)
estimated total project cost= under $5 (i had everything on hand and had to assign a nominal cost
)
thanks for looking!
