Myford Super 7 Toolpost issue

[ZanParticipant @zan]

I use 8 mm tooling and have reduced 1” to nothing in two cut,s, but it’s pushing the machine too much, and was just about seeing what it could do. Now I would use use three The 7 series are small lathes and don’t warrant anything bigger. I use exactly the same tooling in my Colchester student without much problem with decent sized cuts

Is there an engineering reason for wanting to fit oversized tooling to a small lathe? Though my Chinese lathe would take 1/2" shanks, I use 12mm. I've no desire to upgrade the machine to take 15mm tools. Expensive to do for not much return, if any.

Hi Dave,

The reason i want to use 12mm (1/2&quot tooling is that – thats what i have already!

However it is a fair point to say – will it be cheaper to buy a new QCTP system or to buy a complete new set of carbide tooling from China…..hmmmm
