I'm thinking the biggest hurdle with mounting the disc to the cover would be to have enough thickness and be of a strong enough material for the disc mounting bolts to have a good enough bite. Rather than putting the mounting holes in the cover itself, I wonder if it would be possible to make an outer ring that is connected via the existing cover bolts, and then have a smaller ring with the disc mounting holes, the two rings attached together via radial arms. Instead of having a dished cover, make it nearly flat (widening the outer shell) to make this sort of disc adapter easier to attach.
Alternatively - depending on the manufacturing process used for the covers - you could include some solid, thick ribs in the cover where the disc mounting holes could be tapped. Stamped covers I don't think would work. I'm guessing It would have to be either cast or milled.
Oh No I took no offense at all Please keep the comments coming the last thing I want is to order 100 motors just to find out I forgot something and have to rework them in some way. Been there done that and its no fun I can tell you.
The covers I have are casted and I just don't trust castings I'm sure there are voids in the side covers so its going to be a challenge. I'm thinking a machined side cover produced by my shop or I'll sub it out. The only positive thing is that the side cover has steel embedded in the aluminum for the bearing housing. If they could embed steel for the disc mount with a spider that goes out to the spoke hub then I have a good design. Since they know how to cast aluminum around steel it may be easy for them to extend this to the discs mount.
Thanks
