youtu.be/CBFE-Bt7RjY Here’s another one that’s in the us Nice work, it would be great to see how they were made by ge . That was a good one! Yes it is - complete motors and they explain the steps of the process.

Ran across this history of electric motors and magnet wire. Very interesting. Scroll down a bit at first unless you want to read about electric vehicals. mwswire.com/about-magnet-wire/

After spending a few hundred hours researching local history during this lock down I finally decided it was time to epoxy some wingdings Friday. I took some videos and put them all together, its a bit long but oh well. studio.youtube.com/video/VBY9dl4Czbg/editHere are some pics of the finished project. I had to heat the epoxy in the threaded rod threads to get the nuts off. Travis's stator. DR-1 stator I baked this one with the leads up. As you can see the end that was on the bottom has more epoxy on it. Since it has a 45 min working time it might have help to let it drain longer and turn in over several times during the draining. DR-2 staor This one I made a mistake when I chose to put the lead end down while it baked. I had it too close to the foil and the extra epoxy ran down and glued the one cloths pin I had holding the leads to the end of the windings. Oh well I got most of it off and its not like the early ones didn't had wood in the slots to begin with.

Very nice work Gill! I’m glad to see that you’re making progress on these. Very cool stuff.

It looks like you can add one more thing to your resume of skills acquired.

Nice work !
I appreciate your work, you have a business to run so I can appreciate your time is limited. And the forum has learned a lot from you is an understatement. Hopefully we’ll see more!

I was thinking; about the expoxy being heavier on one side; Possibly; you could attach the stator to a shaft so it rotates as it dries. Maybe re-purpose a thrift-store rotisserie BBQ motor? By the way, the new YouTube Studio makes it easy to grab a nonworking link. I couldn't watch your video from the link, but this link works: https://www.youtube.com/watch?v=VBY9dl4Czbg Thanks so much for sharing the progress!

Nice work they should last another 80 plus years no problem. Just wondering if the epoxy got into places that we’ll make it hard to reassemble like machine surfaces that have to mate up to another one . Halving not took one apart , it’s something I was wondering.
I like the rotisserie hope you didn’t steal that from your wife’s kitchen.,

Halving not took one apart , it’s something I was wondering. Good point. I did get too much epoxy in the area were the stator mates to to the compressor. Its supposed to be a soft set epoxy so I should be able to remove it from the lip, just have to be careful. Hope I didn't let it cure too long. I have had a crazy busy year at work.

So I repurposed our old counter top and finally found time to teardown the DR1 pump. Sorry the lighting was worse than I thought at the new bench. youtu.be/FJHZetmMlTg

That was really neat watching you tear that compressor down. If it were an R12 system how would you describe the level of carbon buildup? I’m assuming for an SO2 system it is a normal amount.

It’s been a while since I looked at this post so I looked through it all from start . Very interesting to us fridge geeks! Very nice work. How are you planning to clean the pieces? Ultrasonic Cleaning , or do you let it soak in a cleaning solution?

I have most the small parts cleaned already. I do have a HF ultrasonic cleaner, wish I had a much larger one. I also have some crocus cloth and such I cleaned the piston and such up with.

Now I see how labor intensive it is, if I go this route with my DR-2. It's very tempting, to have a fully restored DR-2 (I need to finish up the cabinet, so I can send it off to get painted). Any idea yet what refrigerant you're going to use this with?

Yes after an extremely busy year this is back on the work bench. I will use the r124 as usual. I have a lot of the parts cleaned and ready. Wasn't sure just how easy the base welds with a mig welder so I did a test run last night.
