I have a project that prompted me to figure out a way to drill a 1 1/8" hole 7" deep in a chunk of aluminum. My mill has a 5" stroke so that was out. I clamped the material to the CXA toolpost on my lathe and put the drill in the spindle. I'm sure that's no big deal for you guys that use milling attachments on your lathes... this was my first time drilling with the spindle.
The work envelope I use on my rotary table varies from day to day. I recently had to mount a 16" x 11" X 3/4" plate on my 9" Troyke. I bought a large 1" aluminum plate and mounted it on top of the rotab. I then turned the OD of the plate to 16" diameter cranking the rotab. I added alignment rings in various increments to the top then milled the center hole. Because I am not limited to the T-slot locations I can drill and tap holes where ever I need them to hold parts. The photo shows my 6" X 6" x4.5" home made cube holding another part needing a radius. -Mike
