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 :DQuote:

Suppose feeds and speeds are important here too. Most of my turning is alu or softer steels.
Is there enough height on a ML10 for that style tool changer?
Umm No. just checked tonight and it is only 50mm from the table to the center of the spindle.Quote:

I used a mix of quick change holders, and a gang tooling block when I had my Conect lathe.
A couple photos can be found in this album over on flickr - https://www.flickr.com/photos/mc_mtb...57625154378941
IIRC they were ER25 holders.
Ive actually bought one of these so if anyone needs info, let me know.
How are getting on with the ATC? is the turned finish similar to a QCTP
Im looking at building one but cant decide on this type with the ratchet and pawl or the pneumatic ones with the toothed register. Seems to be pros and cons to both
I think its decent. I struggled with parting, he uses an alu 'pawl' which ive since machined out of steel, havent tested it yet. For a smaller machine, its ok but it struggles a bit with the heavier stuff.Quote:

My friend has the little denford one and said it suffers from similar issues. We were looking to make one with the pnuematic actuator but seem like a lot of work to me.
I just seen this one http://lukesprojects.weebly.com/auto...l-changer.html it uses two adjustable pawls and looks quite substantial
Do you know if the pneumatic ones are the best option? either way it will be an investment so we want to make the best possible version
Sorry, main block? The mounting block? Probably around 100 x 100 mm but can check over teh weekend.Quote:
