homemade lathe

I am looking into making a lathe....i have parts to make the headstock from an old drill press disassembled. I thought about getting some all-thread and drilling a MT2 hole into one end as a tailstock. Anyone know where i could find bits for that? I have access to a metal mill at work to do the job.

You won't find a drill bit for that. You can find a reamer which will work once you've roughed it out with something else.
If you really want to go that route, find someone with a metalworking lathe and some experience - they should be able to bore a tapered hole for you.

Edit: Deleted something because I see you want tailstock, not headstock.

Insert witty signature line here.

We have that work too but our machinist quit and no one there can set up to bore a hole. however i might look around for someone who can. Also if there better ideas out there please feel free to suggest.

If your shop happens to have this specialized reamer (larger shops will, smaller shops won't), the setup shouldn't be much harder than drilling and tapping a hole. You drill the hole normally, then work the reamer in with a hand tool.

If you don't have access to this reamer, and you're willing to tinker, maybe buy Morse taper "sleeve" ($6.50) or "holder" ($31) from Grizzly, then figure out how to bolt that to the rest of the contraption.

I would be cautious

Drill presses are made to take loads that are in line with the axis of the arbor. Lathes have large and more substantial bearings to take loads that are perpendicular to the arbor. The bearings if substantially loaded, may fail sooner than you might expect, maybe not if loads are kept at a minimum. You might be better off to just use some shaft bearings. Making a lathe threads are
here ...somewhere?

The interface, chuck or faceplate is the next challenge. The connection whether a threaded or tapered fitting is not easily done without specialized tooling/machine. If it sounds like I'm against the idea, I won't say that for sure, but I can see some issues. You may be better off finding a used lathe on CL that's 90% there all ready. I donno? bill

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Hadn't thought about the horizontal load verses vertical...you have a very good point there. CL is really good and also alot decent repairable lathe but price range and transport range is an issue. Definitely need to keep looking for solutions.


Thanks for the info.

Shopsmith is basically a drill press laying on it's side and used as table saw and lathe. It makes a crappy lathe with too much vibration. Mostly due to bearings that are too small and too closely spaced.
