As I have thought about working on the bike, I kinda want to tap the crank arms to allow for a standard SPD pedal. It is really the only "upgrade" I will be making to the bike. Just wanted to make sure I wasn't. Seems like it would be easy to do but I just want to make sure I am not affecting the value of the bike. Not that it is overly valuable but I don't want to do something today that in 20 years I will say why on earth did I do that. I would like most people would rather have english threads?

Check ebay or the Steel is Real Facebook Page, or the classifieds here for a Stronglight crank, My Mercier was built in 1971, and came from the factory with standard, I.e., non-French pedal threads. It might save you the hassle of re-threading your current crank, and you could store it away if you ever had the desire to put it back to all French.
Re: the front derailleur, I put a thin flat washer between the 2 derailleur halves to keep it from being over torqued. So far so good.

Coincidentally....
https://www.bikeforums.net/classic-v...-crankset.html
Here you go. Already has the correct sized pedal threads. Looks like the arms are mismatched with one originally French threads, but the seller says it accepts standard pedals, so I think it's been re-threaded.

My PX-10 came with pretty beat up pedals that were no fun to use. I found that good french pedals were hard to come by so I tapped my cranks. If you have good pedals, you may want to save the cranks and pedals and replace them with something more user friendly. One of these days, I'll get some French retainers for my Phil Wood BB and install newish T.A. cranks.

We need pictures of the bike taken from the drivetrain side.

well I’m not sure if it was by my demise or it was already cracked but regardless is it cracked....
i read there are are plenty of alternatives but I’d really like to stick to the simplex brand and come up with something that is all metal to avoid the cracking in the future. Could anyone offer suggestions. I was thinking of the simplex sj a102 but I read conflicting opinions if it will work or not. Anyone else got a suggestion using a simplex all metal FD

Found this metal Simplex front derailleur - front portion- on e-bay, a few years ago.
It has held up just fine mated to the plastic back portion.
Incidently, I think you are making a regrettable decision to alter the bottom bracket. I would keep it original, and have on mine, never a problem.
Sorry for the poor quality photo, but it is dark in my bike room.

If the 58-inch bottom gear is a bit too high for you (it would be for me), you could substitute a larger freewheel, which was a very standard out-the-door mod. we did on almost every PX-10 or PR-10 or PA-10 we sold.

j, the choice of front derailleur has no relation to the choice of bottom bracket.
Keeping the bottom bracket (& fd) original is merely a personnel preference, and perhaps a consideration for a future owner, or future salability.
I am of the school that cherishes originality for best value in the long run (& ease of maintenance). With a proven record in such.

Congrats! I harbor a desire for one just like that! The pedals look to be Lyotards of which I have a pair. I changed my Stronglight to standard threading ignorantly by forcing the new pedals on. It still works fine with little to no long term damage. In retrospect, tapping would be better. Like others suggested, I would keep them in a box and find a replacement crank set with the right threading.
From Speedplay pedal history
Lyotard Model CA45 1940's-1970's
France
This nice quality lightweight alloy quill pedal was sold at a very competitive price for many years.

I kinda lucked out on the pedals. A guy from another forum had some laying around with French threads and is sending them to me for free. They will be here in a couple of days. Universally everyone seemed to think that while it could be done, it probably best to avoid for a multitude of reason. I’m sure everyone is right so how could I turn down his free offer. It was really nice of him.

Fork
Would one of you mind measuring from the bottom steering lug to the center of the front axle? Preferably a 58cm frame.

+ 1 on the Lezyne its my go to pump and I use the bottle cage mount bracket but its small enough to fit in a bag or a jersey pocket. I will note that I don't pump up my tires to max PSI.

Looks like a good one. You will need to clean it with white polishing compound and then wax, of course. Replace the old brake cables with lined stainless ones and stainless derailleur cables. Replace the old, hard Mafac brake pads with new ones, preferably Kool Stops. You need a special Stronglight or J.A. Stein 23.35 mm crank extractor for that Stronglight 93. Be aware that only those will work as others will strip the threads. looking at the crankset, you may want a lower gear option as your inner chainring looks quite large.Red Clover sells a 37 T inner ring which might help.Lube everything with new grease and good to go.

As regards chainwheel sizes, here in France the norm is 52/42.
Ebay.fr is a good source, as is www.leboncoin.fr.

If you mean from the bottom of the headtube to the axle, it's 395mm. See picture 2.

Thanks
Mines 380mm the bike has always felt like I was falling forward. I'm thinking this could be the reason. Bike was just a rusted frame when I got it with everything cut off and no fork included.
