Quick-change toolpost for a Zyto lathe - what size?

I am busy bringing my Zyto 3.375" lathe up to a useable state, and I've managed to get it working very nicely with a VFD.

My next mission is to look for a quick-change toolpost system, but I have absolutely no idea about the best size to get. Has anyone with the same lathe fitted a QC post and, if so, which one did you get?

Hello David,

I imagine it will be of similar size to the ones that fit Myford lathes and suggest you look at those.

Regards Brian

Old Myfords, perhaps (ML1, etc) but not sure whether the centre height being 1/8" lower would make a difference?

That really depends on the height of the topslide 'deck' relative to the spindle centre - IIRC an ML7 has 5/8"..

I'll have to go and check it!

Thanks for the info.

David,

As has already been said, it is all a matter of measurement. Take into account the size of your tooling, height of the toolpost mounting surface to centre height and compare with the dimensions for a given QCTP. For example, my lathe is a generic 9 x 20 Asian clone and I use a model 000 wedge-type from Uncle Ketan's Emporium. I'm very pleased with it. Have a google for videos on YouTube. There are several on there that explain the method of selecting the correct size.

That page also has links to articles on fitting such a toolpost to either a mini lathe or a Myford, so I'm pretty sure that size would suit your Zyto.

I dare say you could get away with a larger one, but I don't see any benefit to be gained by doing so.

I have the small Myford compatible Dickson from Chronos on my Drummond B Type .which is a bit heavier than the Zyto but comparible, Its fine for most everyday lightish jobs but I still keep a simple shimmed holder for''heavy'' work without the topslide , the key being the extra rigidity. Heavy is of course a relative term but I'm sure you get the gist .
