Lathe Spindle Thread Look-Up Table

Use the table below to quickly look up the spindle thread of your lathe.
 

Versachuck wood lathe chucks require a backplate that is compatible with your spindle thread - the product code you need is listed next to each thread size.

Versachuck backplates conform to the ISO standard Pratt Burnerd 4" system, and therefore, as well as our own Vesachuck bodies, they are compatible with many other chuck bodies, particularly engineering chucks and older Axminster chucks. The drawing below shows essential sizes for compatibility.

We have alphabetically listed every woodturning lathe we can think of (although there are probably a few we've missed), which we have produced in good faith and which to the best of our knowledge is correct at the time of writing.  However, lathe manufacturers reserve the right to alter the specifications of their lathes, so please do double-check your lathe spindle size for yourself, as we cannot be held responsible for any errors or omissions.

(And if you do spot any errors or omissions, please feel free to get in touch to let us know)
