Peugeot Corvier Read Axle bent
I have an old Peugeot Corbier that has a bent rear axle, it is not a huge bent but noticeable when spinning the wheel. I would like to find a new axle but I am having a little trouble with measurements & source for this same axle.
The read wheel has a maillard freewheel 24 spline, with a Sachs Huret hub (?), the axle is measured by ruler end to end 163 mm & 8.77 mm diameter in center measured with caliper & 9.30 mm over the threads. It looks like this:
Any help would be greatly appreciated.
Thanks

bronze tools let you bang on it without messing up steel threads, because, bronze is softer.
you might be able to straighten out, what you have for now.
have you asked at your LBS or you want only online stores ? I have no input on the latter..
C&V may have some horders of discontinued parts like old Peugeots require

First of all, a bent axle doesn't affect the spinning wheel in any way, because the axle is stationary. Yes, the axle will wobble when it's spun while the wheel is stationary, but that's not an issue in the real world.
I suspect that you have a 9.5mm axle (threads often measure short because the crests are truncated), and they are available from a few sources. However, no harm will come from using this axle either as is. Or you may try to straighten a bit by mounting the cone and locknut and setting it up against the bend. Then stand in a vise and use a piece of pipe to lever it, or gently tap it home with a plastic mallet.
Either way, use the bad side to the left, so the stronger, undamaged side is on the right where stresses are higher. If you don't straighten the axle, it's orientation may slightly affect the wheel position, so mark one spot so you can always mount the wheel with that spot in the same place.

C&V? Sorry I'm quite new to the slang.

As mentioned by FBinNY, many confuse freewheel wobble to a bent axle. Freewheel wobble is pretty much normal. while bent axles should be fixed, a small amount freewheel wobble is pretty much normal for about 90 percent of freewheels out there. It was just acceptable manufacturing tolerances involved in putting threads on freewheel bodies back then, that is in play. Best way to fin out whether you have a bent axle is to roll the axle on something really flat and true like a glass table. If there is a hop when you roll it, then you can find out where it is bent. If you are competent enough a mechanic, you might be able to straighten the axle yourself using creative methods with hand tools but it would be easier for most to just change out the axle.
I've straightened out a few steel axles through the years using a plastic dead blow mallet and a good sturdy surface (These days, I use a section of heavy rubber parking lot bumper stop to act like a resilient anvil) to put the axle on while I give it a few measured, careful blows from the mallet and checking it for straightness on a glass surface. As long as the bend is not too bad, it should be easy enough to straighten the axle, but if the bent is too much, you might end up with an axle that will be weakened if atempts are made to straighten it. You have to make that call whether to bother fixing it or just replacing it.
Lots of spare NOS axles always for sale at eBay, so you most likely will find the right one easy enough if you have to go that way....

Roll the axle like a pool Cue how bent is it?
