PMD 4:1 brand new split

Kaf, I wasn't trying to say it was a badly designed part I was just wondering how he did the final machining. Te first pics it was hard to see the full radius of the bearing and it looked as if he may have gone right into the cap or just machined straight down around it. With the angled pics I can see a lot better how it was done and it makes sense because you can see how it was machined around the bearing cap, and not straight down or right into it.

As for repairing it, IMO I'd say it probably wouldn't hold up unless its welded. The side load from the output spinning and the force (even though its not a lot) that's put on the bearing is prob enough that any type of epoxy or aluminum weld putty may hold up for a short period, but it would probably just rip apart again. If your really good at welding you could do that and it would be fine as long as its lined up accurately.but again being such a small piece that won't be an easy task to do.i don't really see any other way myself, maybe a more seasoned machinist would know better.
