M33 tap

strat · 11 Dec 2016

Hi

I have a Perform CCSL lathe with a thread of 1" x 8. I have a tap to create matching thread in wood to make "accessories".

I now have a new lathe with M33x3.5 thread.

Question is does anyone one know where I can purchase, for reasonable cost, a M33x3.5 tap and possibly die for creating threads in wood?

Many thanks in advance.

Beall do one. if the toolpost dont stock it, they may be able to put it on their next order. The die may be harder to source

A M33 tap is a big beast and new ones are not cheap, unless they are far east imports. There is currently a used Goliath one on ebay for £20 or best offef, plus £4.50 carriage, which I think is reasonable considering you could use it on wood, aluminium and steel (if you have the muscles). I wanted a 1 1/4" left hand tap to make faceplates etc for my Viceroy, and they were advertised for £60 plus. Ebay came up trumps again, a set of 3 for £49 - not cheap but very useful, and I may be able to sell them on when I have finished with them (although I have not actually started with them yet).
Keep lookinv though, because these do appear from time to time. I bought a 1 1/2" x 6 for my graduate for £6 - not used that yet either. I did try cutting a large thread in steel a while ago using a long tap stock with the work in the lathe chuck and pressure from the tail stock. Like I said, needs muscles.

Dies tend to be dearer still, although again one on ebay for £23, but no make stated. Probably fine for wood and aluminium though. Agsin, keep looking unless you are in a hurry - I bought a die for my ML8 for abouf £5 (1" x 12).
