I've moved onto cleaning up the chassis. I also gave the tube shield a fresh coat of metallic paint.

The old rubber mounts are rock hard so I'll need to find some new ones.

I think that those mounts were some sort of rubber grommet propitiatory to Philco, sort of like those triangular chassis shock mounts on some sets, I don't know where anyone is making repros or no. The closest thing I can think of to those are maybe shock mounts for a small refrigeration compressor, or you can try some thick washers with the same size center hole. The only other answer would be to make a mold and cast some out of a D.I.Y rubber compound, if you can still get it.

If you go to someplace like Graingers and look for rubber vibration isolators there is a pretty wide selection and perhaps something might be close enough or be adaptable to what you need:

Here is the rubber grommet selection form Grainger which may be worth looking through:

Another option is to start with some laboratory rubber stoppers and adapt them

Thanks for the suggestions. I think I found some items from renovated radios that will work. I needed to order some other stuff from them anyways

My order from RR arrived today. I think these will work out fine.

I've also been examining my speakers more closely and discovered that the Wheelers are not made very well and the cones don't have much spring left in them. So I pulled out the original Philcos for another look. After some careful scraping and compressed air blowing, I actually got the voice coils moving fairly well and decided to patch them up.

Yuck!

Making good progress

I used GC Service Cement and coffee filters to patch up the cones.

I figure if these actually work, I'll recone them properly. I think the radio will be happier with the original speakers back in it

Bob, nice that your putting back in the originals. A lot of work to clean them up but I think you will be happy. Looks like they are coming along well. Nice job.

Looks good so far. Hope the iron windings are OK. Best take it slow on the cones.

I figure I might as well polish up the aluminum IF cans before I remount the tuning cap. I hope to fire it back up tomorrow.

Bob, I'm not certain what you used on those cans, but the came out absolutely lovely. Nice job. Are you going to keep your method secret?

WOW!
Yes, please share! I've never been able to obtain those results on the early 1930s Philcos...yet...

Thanks! Your answer is right in the photo - Simichrome and a cotton cloth. I cut the cloth into a long strip about 3 inches wide, dabbed on a little Simchrome, wrapped it around the can, grabbed one end in either hand and buffed the cans like I was shining shoes. I used the same stuff on the copper caps.
