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. Gary

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.

washered cranks.

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.
