Bench Grinder Restoration (Belt driven)

How would I align the shaft in the yoke? I could try to do it one bushing at a time and use one of the old bushings to hold the new one. However, the bushings are extremely worn out. On each bushing, the inside of the yoke is intact https://goo.gl/photos/1nd9RFiei3fgSXhY8 while the outside by the grinding wheel is worn https://goo.gl/photos/3hoJZ9e5TsqPHNUj9

I don't know the correct answer there as I have never done this. I've watched a few videos and have poured some lead before, but I've not used babbit or tried to pour a tool bearing.

If you decide to go this route, you should look up a guy on Youtube named Keith Rucker. He's got a few videos about pouring new babbit bearings; I've watched a couple and they are pretty informative. Of course, there's nothing like hands-on experience

There is also a forum dedicated to vintage wood and metal working equipment: http://www.vintagemachinery.org/ There are likely a couple of good wiki entries on the subject, and there is an entire discussion forum to search. Lots of good folks over there; if you get stuck in the process I'm sure they'd have the answers you seek.

I really wish I could tell you more or lend a hand, but this is outta my depth of field for sure.
