    Default ER16 "Quick" Change Collet Chuck System

    I have a limited number of sets of ER16 Collet Chucks modeled after the tooling system used in the Dyna Myte DM2400 bench top mills. It was a limited run on the tools that were made and never did anything with them.
    They are being sold As-Is for $239 for a set of 8 holders, 1 special spindle nut, two wrenches and a tightening fixture. When they are gone they are gone. Contact me directly if interested.

    Marty mind if I share these on the Sherline site? I have a set of the Dyna's and always thought they were a great idea.

    A lazy man does it twice.

    Not a problem at all. I just used the Dyna Dm2400 as a basis for the design. They may be helpful for all bench mills with an ER16 spindle taper. Though I don't know which machines had those.
    They do eat a little bit of "daylight" under the spindle, but that's not a problem for the DM2x00 series because of their spindle head post.

    I felt doing ER16 collet chucks were the most flexible holder so went with those.

    Thanks!
    Marty

    An interesting concept it is similar to the Kwik-Switch system that was used on some Bridgeport mills just a lot smaller

    Mactec, very similar concept.
    Always wondered why Sherline didnt run with it. Dyna had it figured out for a manual repeatable tool change.

    The only problem is the tooling makes it to long for such a small spindle, just to much stick out for stable cutting

    Yes the actual Dyna ones I have just have a bore for the specific tool diameter.
    They dont use an additional ER16.
    Much shorter stickout than these but still lock in with the same kind of clover nut.

    Dyna Myte's allow you to adjust the headstock up on a post giving you more spindle daylight.
    Such a small machine, they work pretty well. The spindle motor is a small 1/2hp DC Brush motor.

    yup, that's why is only $239 for 8 holders

    I have a DM2400, purchased from Marty nearly 2 years ago, which includes his spindle collet system. It works very well. Never had any kind of problem with stickout. Everything remains rock solid.

    What I really love about this system is that numerous end mills can be pre-mounted in their own collet chucks (which position precisely and reproducibly in the mill spindle), and the tool heights measured and stored ahead of time. Tool changes during a job are thus fast and easy - no need to measure the tool height every time you change cutters.

    I've machined aluminum, plus several flavors of plastics.

    I get it guys. It may not be for everyone.
    I know of one guy that tested it on a Taig and he was happy.
    I know of two people with DM2400(John who "Hman" is one of them who has had a set for awhile and got some extras. I think John has a friend with a DM2400 who got some for his machine as well) that didn't have any of the original tooling and were really happy to find them so they could setup their tooling and tool library. (Both were converted to new steppers and Centroid Acorn)
    If you buy direct from me instead of ebay, I can save anyone here the 10% ebay commission, so I'll sell a set to anyone here for $215. I'm picking up USPS First Class Priority Shipping.
    I have 8 sets left.

    Thank you!
    Marty

    Yes they will work very well for light cutting in the materials you are using, I used to make some solid tool holder for them which only stuck outside the nut by 3mm, which worked very well for steel and any other materials you wanted to cut

    I would like to get some of the main spindle Nuts if Marty has any
