Hi. I’m new here. I have an old montgomery wood lathe.
My head stock has a 0.495” diameter shaft. It currently I was hoping to add a pen mandrel (with a #2 or #1 morse taper) and wondered if there is any adaptors that can be used.

Thank you in advance!

Does the end of the shaft have a threaded hole, or is it solid? That might be a tricky part to find, most lathes have an outside threaded shaft with a morse taper inside.

You might be able to combine this:

with a coupler:

And then find a 1” to 0.5” shaft reducer. A lot of work and fittings, though.

There is an adapter for the shopsmith that attaches via a set screw, although their spindle is 5/8”, not 1/2”... but you might be able to use one with a reducing bushing if you can find one. The shopsmith one will give you a pretty standard 1”x8tpi spindle. Either way, it doesn’t seem like it would run very true attached like that.

Alternatively, is the spindle hollow… have a taper or threaded hole? One last ditch thought – if you have any machine shops in your area (or have a metal lathe), you could take the spindle and have the end threaded.

Cheers,
Brad

I don’t know of a 1/2” adapter. You could have one made but unless you really love that lathe, I wouldn’t spend any money on it.

This won’t solve your problem but might be useful if you go lathe shopping

Thank you all. Yes the spindle is solid. I was hoping to get into pen turning and bought this one. As per many people’s advise, I’ll look into getting another lathe.

Have your say...
