    G0704 Power draw bar from midwest machine works

    I picked up this machine second hand and it's been converted to belt drive with the midwest machine works power draw bar.
    I'm trying to setup the power draw bar and when I do as pictured the spindle is running really hot like the bearings are getting compressed by the washer stack.
    Should the large black washer on the bottom be there?

    Any help or suggestion would be greatly appreciated!
    Thanks, Yancy

    That is a terrible design. The draw bar should be squeezing the stack of washers without applying any pressure to the spindle. It's just jamming the drawbar down against the bearings, probably messing up your pre-load. You should have some sort of lift plate and a top hat that threads onto the top of the spindle. The stack then goes on top of that. The power draw bar then lefts up and pushes down to squeeze the washers. Look at Hoss's design.

    Really disgusting design, I got into the same problem when I took and bought on one site the same detail. You can say that I was deceived at all, I know why I fell for it, the site was very beautifully designed with beautiful widgets here not one girl can not resist. It's probably necessary to be a professional to sell a bad thing so that you do not notice it? I was interested in this idea because I wanted to do something like this for my hardware parts store, using for example magento 2 featured products. I think if I could not pay attention, then you can make good money on this, but I think it will not be a bad idea.
