I have a thread going for a Blackhawk S4 and Hein Werner O'Boy jack restoration. It is a poorly named thread and not getting a lot of traffic. In any case, I'm stuck and need some help. The thing that has me stumped is the bearings for the rear wheel. The bearings are completely gone. I can't find OEM replacements among the normal suppliers.
I see three options:
1. Source a bearing for a 2" bore for a 1 1/8" shaft that is .375" tall.
2. Replace the bearing with a solid bronze bearing sleeve.
3. Machine new bearings.
I can't find bearings, but would be infinitely grateful if someone could point me in the right direction. For the sleeve idea, I'm not sure how well it would work. I know machining new bearings has been done before, there is a thread here on it. However the OP has not signed on in over a year. I have designed a bearing based on the pieces I have left, but I'm not sure if it will work or not.
The bearing design can be found in the other thread here
I would appreciate it if anyone has feedback or experience with idea #1 or #2. I also need feed back on the bearing design. It is an angular contact bearing, but it has a fairly extreme contact angle. If this thing was going to rotate with any speed that would be bad, I think (but am not sure) I can get away with it it will likely never see more then one complete revolution.
Thank
