Who's making the repro "notches" aka "pedal cams"? I have an idea and a request for the person casting them.
and just for fun, here's a link to a video "short". I'll be doing more and more Model T videos over the coming months and hoping to increase my audience. I hope you all will follow along.

Not sure who does them, but the one I got was better than the worn original I had on the brake, but not as good as the slightly worn reverse one, so I put the new one on the reverse and the old reverse one on the brake. Next time I will take my old worn one and build it up with weld instead so I can get it to near new quality.

New notches should not be seen as a cure-all. The notch is one half of a pair of components. Both wear. A new notch takes out some wear. Building up the other piece with weld and dressing it down to suit is the best solution. This is where the true value of a new notch becomes obvious. It can be used as a reference piece when dressing down the welds, to make sure you have the best contact between the two working surfaces. Getting the correct form on the welded ramp takes time and care, not to mention some skill getting BOTH ramps engaging at the same time.

You are on the right track with this. Welding up the pedal side is a PITA.

I finally found my notebook after 10 years - Is Ken Meek still in here? I have a note in here about pedal cams. I can't remember what it was exactly, if he was welding them up or casting the notches...

Ken Meek was tragically killed in a Model T wreck many years ago.

Tim, I have done a few of these, but only for my own use. There is too much time involved to take the job on for others.
Early on, I did a first gear pedal/notch set for myself. I thought I had done a wonderful job getting rid of all the slack, only to find that the first gear pedal needs some free travel to be able to hold the clutch disengaged for neutral!!!!!

One thing I have learned is don’t mix a NOS cam with a reproduction slow speed notch. They don’t like each other.

Since the notches are a spiral design they need to match that of the respective pedal. A new notch will not always mate well with a worn pedal.
Here is am older discussion if interested.

If the cam & pedal ramps are good & smooth but worn I weld up the hole in the cam, add some to the outside & mill a new hole to put the
peddle in the correct possion & travel. I only do this on the brake & reverse, low always gets the cam & notch replaced. I also ream & use tapper
pins. I have found broken split pins, bent roll pins & grade 2 bolts in pedals & low notches. I have seen a grade 8 bolt threaded into a low notch.
With the thought that you could replace it without removing the HH??

Since you have to grind off the head and drill the retaining pin on the low pedal - I'm going to say "no".

Hi Tim,
Someone tapped & installed a grade 8 bolt in the notch thinking they could remove the bolt and slip the shaft out and replace the notch & cam
without taking the HH off.
