Lathe ATC Options?

The turning tool holders look easy to make in a larger size?

Perhaps. Ive not seen the kit broken down like this before. It might be where the 'centreline' is effectively which is more challenging.

Given that they mount in the same holes as drilling and boring tool mounting holes then the centre line is the mounting hole centre line, no challenge! ;-)

True. Spoken to him, he will likely be able to mod these to go to 12mm. I can then probably make my own later if I want to go to 16 or 20mm tooling.

Bonus! :D

I did see that one but put off by the small tool capacity. May have to message him if it can hold 12mm

I'm currently using 16mm tooling with a large QCTP and getting a nice Finnish so don't want to go down to much in case the finish quality is reduced.

would also need to buy all new tooling

He can mod to 12mm. Anything larger needs new holders done.

Just messaged him so find out soon enough.

looking at the pictures again it does only have 1 pawl on the ratchet so that might limit the force it can take

I use tooling from 6mm through to 25mm+ shank on my Myford Super 7, by milling a relief pocket on the holder side of the shank which just accommodates the bottom lip of the Myford size QCTP holders the ability to use the tool in a larger holder isn't compromised, rigidity isn't reduced to any significant degree and centre height isn't an issue :D

Is there a view on what size tool is required? For my Harrison M300, this is a semi beefy home lathe. 12mm almost looks too small. I spoke to Kenny last night (dude selling the stuff) and he says on his Haas CNC lathe, he tried bigger tools (20mm etc) and found that they took up too much space and settled with 16mm. Suppose feeds and speeds are important here too. Most of my turning is alu or softer steels.
