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.
2016-07-25.jpg


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.

2016-07-25.jpg
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.:grin:
estimated total project cost= under $5 (i had everything on hand and had to assign a nominal cost:cool 2:)
thanks for looking!

That's a cool project, Mike. I can think of a couple instances where I could use such a tool.

Did you use the back gears to lock the spindle or do you have a slick indexer for the spindle?

Thank You Nez,
I used the back gearing for positioning, but i'm going to need to make up an indexing plate of some kind.
it was pretty easy to make, machining the shaft to fit the bearings was the time consuming part.

Very cool idea!
Thank you Mikey!

Nice job Mike.
Thank You Thomas!

Great idea, saves all the trouble of relocating on the DH on the mill.
Looking forward to seeing progress on an lathe indexing plate.
Please be sure to post pics and concepts...

Very slick indeed! I particularly like that you simply re-purposed stuff you had on hand. It's amazing what one can do with a little creativity and a good collection of "stuff" that many folks might think worthless. I think I'm going to put this one on my project list. Thanks for the idea!

Cheers

Very nice, indeed! I can see one in my future, too. . .
Why thank you Frank!

Nice job Mike :high 5:
Hi kd4gij,
thank you very much for the compliment!



it really makes a guy feel good, to have a bunch of great guys to bounce ideas off of as well as learning things yet unknown.

be it from the fool or from a master, a lesson is taught to any who may inquire.

Hi Mike,
I finally built one a few weeks ago (I had to order the bearings), used it immediately, and then finally photographed it a couple days ago.
Great idea!
Thanks
