Helped my son purchase a South Bend recently with the idea to make these (shown in the middle). This part is for a Lazy Boy chair leg extension. A repairman came to our house last year and explained he can't get metal ones anymore and is stuck using a plastic version as shown on the right. The plastic ones don't last. So that's our first goal. I've looked all over the internet for a similar shoulder bolt and cannot find one with the correct dimensions. So here's our South Bend being installed. There are a few parts to be put on yet after cleaning. Also need new belts and probably a new motor. And here you can see the tag on the machine. It looks like a great website you all have here.
