    That is a 1/2 shank bit.. 5/8 90V.... It's not a hex nut on there, even though I didn't order the M, it had an M type nut.... I bought it based on the image and the size of the spindle shank..... UR system looks pretty good there !! Lock button, vac cap... NICE !!!

    Bumping into an old thread again...

    Could the lathe be skipped altogether?
    If you start with the C10 ER11 piece (chuck diameter 10mm), cut to proper length and then use the following bearings:
    1. top = size 6000
    2. bottom = size 6002/10 instead of 6002. The 6002/10 is also known as LR200. Dimensions are 10x32x9.

    That could simplify the construction process a little...

    • model A, QC, firmware 1.188, sandpaper belts, "brainless"
    • model A, Carvetight, rubber belts, A907, illuminated display from soigeneris (Jeff Birt)
    • 2 x model C, Carvetight, still in box

    I do not see any reason why that would not work. You still have the problem of making the square flex hole and the clip ring slot.

    Are those Er collets blanks that can be machined to whatever is necessary? If so, that's pretty nifty. I made my own spindle that accepts standard porter cable router collets. Love it. Perfectly balanced and I have plenty of wrenches, lol

    Yes, you can buy these ER extensions with different shank sizes which you can turned. They are usually ,however, hollow and have to be plugged to make the square flex hole in the end.

    Tim.... Thank You for Sharing This little DETAIL..... I am pretty excited to hear about this.

    ​BREAKING NEWS

    This NEW Spindle will be the same as the CT as it is one single shaft but had a standard PORTER CABLE ROUTER CHUCK in EITHER 1/2 OR 1/4...

    INSTALL WHAT YOU NEED. Either a 1/2 inch or a 1/4 inch...

    This SINGLE SHAFT can be INSERTED into a OLD QC Truck making it similar to the CT BUT you can put a Porter Cable 1/2 or 1/4 inch chuck on it. And will use 2 wrenches to tighten. I look forward to seeing them in PRODUCTION....

    Another INNOVATIVE Project from TIM.

    Thanks TIM. !!!!!

    Yes, sorry... forgot that one. Realized my mistake when I started disassembling the Z-truck. And - lucky me - I managed to do the job without any fancy tools, even without any excess force. Yes, I used a hammer to do some "tapping", but it was while holding the truck in the other hand as only support, which means that my hand sort of "cushioned away" most of the impact.

    Btw, how sure are you that those ER-rods are hollow? I studied the images on Ebay and failed to see it. What would you plug them with? Some kind of epoxy steel?

    I am pretty sure they are all hollow. I brazed plugs in the ends. I did not care about the effect of heat because I later turned the shanks down.

    OK, "brazed" implies quite a lot of heat, which will require machining. How did you make the square opening?

    By hand with a small square file.
