Excellent reply. I have always just recommended cutting the slot
bigger to get more clamp force. I did not think about knurling the shaft.
I like that idea.
Knurling the shaft is the term generally used for making grooves in
the shaft. Knurling does not cut the metal it rolls the pattern into the
metal. This work hardens the metal or it should work harden the metal;
which should give a harder and better surface to clamp on.
You would probably need a gap bed lathe or a manual tool if they
exist for this job.

Subject: Re: [Tigers] Accelerator Pedal Slipping
I had the same issue. It is fixed now.
If you remove the pedal from the shaft, you will see that there is a cut out
that decreases in size of the opening when you tighten the bolt which crimps
the pedal to the throttle shaft. Mine was just about completely closed when
tightened. I cut some material of off one side which allows the opening to
close further. Additionally I cut groves across the clamping face to make
b teethb that would bite into the shaft. I also replaced the bolt because
it was bent. Now a gorilla canbt get the pedal to slip on the shaft.
Also, make sure that the floor stop is there and properly adjusted. That
way, at WOT, you are not putting undue stress on the pedal and throttle
linkage.
