morse tapers

Hi,

I have an old Craftsman lathe (from around 1950). The spindle has no threads, only a flat onto which the faceplate is attached with a set screw. This poses a problem when I want to use a bowl turning chuck, all of which seem to screw on to the spindle. My question is, does a morse taper exist, which comes out to a threaded section, onto which I could screw a chuck? Should I take the spindle to a machine shop, and have threads put on it? Is there another way for me to get a bowl chuck onto this lathe?

Thanks

Curt Blood

Seems the Shopsmith solution might work. Buy the plain insert, have it bored to fit the shaft and crossbored/tapped for a setscrew.

Heck, if you have a 5/8 shaft, just get the insert for Shopsmith.

Go to someplace like Kitts, J & L or Production Tool and get a MT 2 arbor. Machine shops use shanks like this frequently.

The weight of a chuck, plus the wood would put a side load on the Morse taper that would probably make it loosen. Add to that the possibility of a catch twisting the taper.

The "Shopsmith" solution is probably your best bet. Don't invest too much in this. My guess is you will be upgrading to a better lathe within a year. So, if you buy a chuck, make sure it has a replaceable insert.

MT arbours are available ready threaded for a chuck at one end, but also threaded for a draw bar which then goes through the head stock to a retaining nut on the other side of it from the chuck. They are in the region of £5 - £10 on EbayUK, which is about $9 - $18, plus the cost of a bit of allthread and a nut for the drawbar. This would stop the chuck and arbour working loose from the MT socket. Look in the general lathe secion, rather than the woodturning one though.

I agree with Leo.

This might a good place to suggest an old dodge re headstocks & Morse tapers. Some cheaper lathe 1X8 spindles with #2MT don't have much meat to prevent being deformed by a catch on a heavy blank. Like the old ad that "motor oil is motor oil" being risky, so is the proposition that "spindle steel is spindle steel".

As usual, I digress and meant to suggest inserting a #2MT plug to strengthen the spindle when turning a heavy blank on a faceplate. The plug can be cobbled from a worn out drill bit with MT shaft, usually free for the asking, if accompanied with a small turning, at local machine shops.

HTH (hope this helps)
