pedal washers -- online source?

Harris Cyclery has TA, I think. There is a person who has been putting TA ones
on EBay regularly

Minor point, but the ebay ones linked to are specifically *not* TA
washers-

"... These pedal washers are identical in dimensions (O.D., I.D. and
thickness) to the TA washers but are a significant improvement over
the TA washers because these are made of corrosion-resistant stainless
steel."

Item number: 3672414834
On Ebay for $2.00 pair.

This is actually a marketplace question but I don't mind so much ....
My question is technically oriented: what's the purpose of pedal washers?

I got mine from a firm, Metric Specialties in Burbank, CA,
800.800.6696. I think it is called a DIN 1440 flat washer. I got 2
and 3 mm widths. The washer is wider than the pedal. I think that is
good because it stops the pedal from gouging the crankarm.

I'd guess that if you went into a well stocked hardware store with
your pedal and a caliper, you can find a steel washer that would work.

The explanation I've heard is to prevent the shoulder of the pedal
axle from wearing or fretting the surface of the crank. TA has a
recess around the pedal eye on their cranks so that the washer doesn't
increase the "Q factor." I have to say that in the 30+ years I've
been riding bikes, I've never yet experienced a problem with
un-washered cranks.

Jobst's method of creating a conical interface between pedal and crank
probably answers whatever issue the washer is supposed to answer, and
might well do so better.

My thinking is that it would not work as intended. Placing a steel
washer in front of a steel spindle shoulder to reduce (fretting?)
wear? It doesn't make sense to me. Well intended, but ineffective.

I'd like to have this done since Jobst's explanation of the
crank/pedal interface makes so much sense to me but, since I've never
broken a crank, the expense probably isn't worth it.

The problem is that the contact face is parallel to the force applied
and that can't work as we see from the need for a left hand thread on
the left pedal. The joint is always moving. Placing a washer between
that face does nothing to reduce that motion. In fact part of the
fretting failure is INSIDE the thread although it is most visible on
the face of the crank when the pedal is removed.

Well, you don't have left hand threads on your car wheels anymore and
we wouldn't have them on cranks either if the shoulder were tapered as
wheel lug nuts are.
