[R-390] r-391 motor bearing question

[Scott, Barry (Clyde B)]

McMaster (www.mcmaster.com) is a good place.  Also try Small Parts.  Not sure of the country of manufacture for either of these.  You should be able to call McMaster for details on an item.

I am still refurbing my R-391's autotune.  I still have a lot to learn,
but am making progress.  I'll share my notes with everyone when I'm
farther along in the process.

The DC motor needs attention.  Among other things, I need replacement
bearings.  I need two .25" ID, .75" OD, .25" thick bearings.  They are a
relatively standard size, as near as I can tell.  I'd like to get some USA
made bearings.  Anyone know of a good place to go for standard size
electric motor US made bearings?  Do they exist?  I know where I can get
Chinese made ones.

I also would like to find replacement brushes (I bought some from a HW
store that I can make work).  Are there any good places to find electric
motor brushes?  My web searches didn't really turn up anything.

Thanks,

Paul
