    My first part, a router mount. Its wrong as I only know how to use PyCam to do engraving(Gravure) at the moment and it traced the line instead of cutting out the outline but its a step in the right direction.

    Fixed!

    I found this mount design on here somewhere. The compression tabs were really thin for wood so I fattened them up some. Anyone else needs a wood mount for a Dewalt DWP611, the DXF is attached below.

    Are you going to remake your router with oak?

    If so, I have a few suggestions.

    First I'd use baltic birch plywood, or bamboo plywood because they are much more dimensionally stable than oak (and strong in all directions.)

    Second, if I was going to use oak, I'd make all my critical pieces, especially the risers go with the grain of the oak. If I understand what you have laid out, your risers might fail due to a crack along the grain. (edit, after looking more closely at your picture, it appears that is oak plywood not solid oak. correct?)

    Third, if I did use plywood, I'd still pay attention the the face grain. In many cases the long axis of the face grain is more resistant to bending than the across the grain.

    Its Oak plywood and after I cut out my pieces they will get a coat of Minwax Wood Hardener on them just in case

    ....

    I'd heard about a batch of chinese motors a few years ago that
    had that exact same problem. I hope there's not more of them to come.

    The problem was bad welds of the shaft to the motor rotor. I'd always assumed
    before that that the shaft was all the way through the rotor, so I
    was surprised to find out they weld them.

    Also, some assumed it was due to solid straight couplings. Which isn't
    exactly true. It was just bad welds, pure and simple. No shaft should
    crack off so easily on any motor of any sort. I've used solid couplings
    in the thousands and never have seen a cracked off motor shaft....and
    I've seen some serious mistakes on some of my machines.

    Sorry to see that....

    John

    It has happened to me on a 380 oz motor also, and it had a Delrin coupler from DumpsterCNC on the shaft. The weld is a fused joint from not high enough current applied. There is only a small pit slightly off center that was holding the shafts together.

    I also had a non-flexable DumpsterCNC coupler on. When my new motor gets here it will be getting a flex coupler.
