    You think that's too expensive? You're not a Model Engineer are you? :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.

    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.

    Looks like it will have to be custom made if I go down that route. maybe try gang tooling first.

    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.

    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.

    Thats for the heads up. what size is the main block?

    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
