I've gotten felt sheet and bobs made by these guys in the past
http://www.hardy-hanson.co.uk/ , maybe you can blag a sample. If you
needed 1/4" sheet I could probably send you a piece.

Chris,
I would rip out all the centrifugal stuff and install a sinpac switch
in its place... the centrifugal parts will just be a problem again in
the future....
OTOH, why does it have to be felt - why not some kind of plastic, as
that would last longer. It just has to activate the switch, right?

Is the felt they make battery terminal washers a dense enough felt,
Chris? They're approximately the correct size.

I'll bet part of it's function is an oil wick, so you need to
provide a suitable substitute. But a separate plastic washer in front
of it would provide wear resistance and allow the oil to work around
the edges to the mechanism.

Myself, if it didn't show up at a reasonable price available premade
I'd go find a sheet of the right hard wool felt at a fabric store or
haberdashery supply ("10/6 in this size" ;-) ) to make the washer
myself, and be done with it.

The center hole is easily cut with a gasket cutter or leatherwork
punch cutter, and if you can't find a 1" cutter you can make one with
a sharpened piece of pipe. Or mark it with a compass and use a sharp
pair of scissors, it's only felt and OD cuts are easy...

Chris, try looking at a jewelry supply house. I use rock hard felt
wheels in my hand held grinder and some of those are 1/8 in thickness
and come i 1" diameters. You would have to punch the center hole yourself.

of it would provide wear resistance and allow the oil to work around
the edges to the mechanism.

It might function as an oil wick, I'm not sure. But it certainly has to
be an insulator as it touched live components. I had wondered about
making a replacement out of Tufnol (SRBF), but I think it might make the
motor more noisy, and I'm not sure how it would wear.

Myself, if it didn't show up at a reasonable price available premade
I'd go find a sheet of the right hard wool felt at a fabric store or
haberdashery supply ("10/6 in this size" ;-) ) to make the washer
myself, and be done with it.

I doubt those haberdashery felts are stiff enough. This washer needs to
resist radial compression.

The center hole is easily cut with a gasket cutter or leatherwork
punch cutter, and if you can't find a 1" cutter you can make one with
a sharpened piece of pipe. Or mark it with a compass and use a sharp
pair of scissors, it's only felt and OD cuts are easy...

You can get sheet hard felt from McMaster Carr (among other
places). You can use arch punches to cut the ID and the OS -- and the
main question is "how critical is the concentricity"?. This is the same
kind of felt used to make way wipers.

They're usually a full 1/8" thick but may be too soft. Yeah, ID might

store if you get a chance, though.

Probably not that critical. I have just been sent a pair of fairly hard

Hopefully these will work, but if not someone else has suggested I try
leather (not sure how easy it is to find leather which is 1/8" thick,
though).

I will let people know how it turns out.

You can get sheet hard felt from McMaster Carr (among other
places). You can use arch punches to cut the ID and the OS -- and the
main question is "how critical is the concentricity"?. This is the same
kind of felt used to make way wipers.

Probably not that critical. I have just been sent a pair of fairly hard
felt washers of the correct size by a company as a free sample.

Great!

Hopefully these will work, but if not someone else has suggested I try
leather (not sure how easy it is to find leather which is 1/8" thick,
though).

Hmm ... my belt is averaging abound 0.147", so it could be
sanded down to the needed thickness.

I will let people know how it turns out.

Good luck,
DoN.

I was looking at these:
http://www.toolbank.com/p/D4208/FOO18044

Do people reckon those would cut 1/8" thick felt with a hammer? Or could
I squeeze them in a vice?

I have no idea. The URL appears to be a "built" URL, which
becomes no longer valid when you exit the web site.

I tried it a second time a few seconds later and it came up. But like
you, I got the Oops! page the first time.

Still a problem for me -- even after turning javascript on. :-(

An equivalent hollow punch (set) at Harbor Fright is
http://www.harborfreight.com/cpi/cta...temnumber=3838

O.K. That kind you just hit with a hammer (wear safety glasses,
of course), and use a wooden block under it. Pine 2x4 would probably do
well for a few parts.

Good Luck,
DoN.

Go to any cobbler and buy a leather sole blank. I use one as a coaster
in my office. Looks like a big leather footprint, is 0.200" (~5mm)
thick, and is very hard and dense. I paid about $10 for it, which the
cobbler claimed to be his cost.

The cobbler will have sole blanks in various thicknesses.

Tip: use the end grain of the wood - the punch penetrates much more
easily. Not that the punch has to penetrate very far, but enough to get
through the leather/rubber/felt/whatever.

I've looked at this header time and time again.

are you after a washer you have some real emotion about or you after a
washer made from felt that is hard?

It's weird how people's minds can see things differently. I never
thought there was anything weird about the title. You've got to try a
lot harder with this one than Tom Gardner's "shaft extension" thread.

I want a washer made out of felt which is hard.

Great!

Well, the first try wasn't great. The motor tripped the circuit breakers
in the workshop, and I've yet to figure out why.

Hopefully these will work, but if not someone else has suggested I try
leather (not sure how easy it is to find leather which is 1/8" thick,

Leather sounds promising, but I was told that it loses its stiffness
when it gets exposed to oil. I was also thinking about using Tufnol
(SRBF), which would have the necessary insulating properties. I wonder
if Tufnol washers are available ready made?

Many thanks,

Chris

Are the soles made out of a single sheet of leather, or several sheets
glued together?

I've gotten felt sheet and bobs made by these guys in the past
http://www.hardy-hanson.co.uk/ , maybe you can blag a sample. If you
needed 1/4" sheet I could probably send you a piece.


Thanks for the suggestion. I've sent them an e-mail. I would take you
up on the offer of a piece of sheet, except 1/4" is definitely too
thick.

I have now received two felt washers of different grades from Hardy &
Hanson. The denser grade looks most suitable. Thanks for the suggestion.

Best wishes,

Chris

You mentioned elsewhere that this was an old motor long out of
production. Induction repulsion start maybe. I have one on a compressor,
now on loan to a mate and it is the only one I have run across. I got it
as a recon and it has never given any problems. It is the only motor I
have seen with timing. There is a clamp at the back of the motor to
allow the starter phasing to be altered and it effects the direction and
starting perfomance. The centrifugal assembly appears to be made out of
several dozen, at least, copper segments the flip out when the speed is
high enough. Its largish, cast iron frame and heavy but has worked
without problems for the last 25 years and maybe 3 times older than
that. Never had the need to dismantle it though, which I have had to do
with a couple of newer motors with centrifugal start switches, Gryphon
motors IIRC.

My leather sole coaster does not appear to have been glued.

I did some contract work for an automatic player
piano company. They use lots of felt to quiet the
mechanisms. Different custom die cut shapes, densities,
and thicknesses.

I cannot remember which company but there is a felt
company in LA that had a catalog that had more types
and shapes than I ever dreamed were possible.

I see 3 in Google, give them a call:

General Felt Industries Incorporated
8320 Rex Rd
Pico Rivera, CA 90660
(562) 948-1432

Western Felt & Fiber
323 S Date Ave
Alhambra, CA 91803
(714) 972-2820?
(626) 281-6300

Acme Felt Works
6500 Stanford Ave
Los Angeles, CA 90001
(323) 752-3778

I don't think so. It looks like a regular capacitor start motor to me.
But I would like to see one of those repulsion start motors. I've yet to
see one. Do they look very different on the outside?

I am starting to think that perhaps the insulation in the motor is failing.

Thanks for the tip. I have acquired a washer as a free sample, but if it
doesn't work I'll give those companies a call.

But I am starting to think that the motor has other problems.
