Update on my 1950 Frigidaire WO-65 Unimatic

[vintageteddy96]

A small update on the WO-65, I have disassembled the machine and am currently cleaning up rust and plan to patch the small holes with J-B weld waterweld, then coat the outer tub with bath tub epoxy paint. I also removed the motor/transmission assembly and drained the oil. I took apart the pump because it was making a scraping/grinding noise. The pump was full of mineral debris and the impeller was very corroded and I'm not sure the the impeller will be usable as it has a hole in it. The housing look okay though.

Looking good, you can seal that hole in the pump impeller with 2 part plumbers epoxy putty. It dries hard in about an hour and you can then sand it down to make the patch level. Does the motor start and run without issue?

If you need fresh pump impeller bolts...

Thanks for the info, the motor does start and run just fine. I was also thinking about having an impeller 3d printed in case this one doesn't hold up over time although a 3d printed one probably won't hold up very well either..

I would (and may try someday) make a silicone mold out of the impeller then recreate it using hard polyurethane plastic resin. Would be in interesting experiment to try to see if it hold up for the long-term.

That is a good idea, definitely worth a shot!

I wonder if adding shredded fiberglass strands would help with durability?

Adding Talc powder works really well, I do it for most of my vintage washer rubber and plastic reproductions that are not meant to be see-thru clear. It adds both strength and weight.

This is what I use...

That's good to know!

Here's where I'm at with the WO-65, I patched up the impeller with epoxy putty the best I could, cleaned up the rust on the outer tub and patched it with epoxy putty and then painted it with rust oleum tub and tile epoxy paint. I also just ordered a new capacitor for the motor just to be safe.
