TrueFire Timer Rotor Part Source
I have been helping friends with Model T electrical problems for about 40 years now.
I have helped a dozen or so with TrueFire ignition problems and most were simple to understand and repair.
Two of my friends have had the Timer Rotor do a melt down, due to the engine overheating, in this hotter than usual summer.
A few years ago, I built a test set to test the TrueFire parts and in each case the main component coil box tested OK.
The related melt down Timer cases have not been tested and still may be OK.
The problem is finding a source for the Timer Rotor, as no dealer seems to have any rotors and/or (or timer cases).
Does anyone know of a source?

Re: TrueFire Timer Rotor Part Source
Do you mean the plastic piece with the two magnets that fits on the end of the camshaft? What is the failure mode, does the plastic split, or do the magnets come loose?

Re: TrueFire Timer Rotor Part Source
Yes, that plastic piece with the magnets is required.
The magnets hold their strength forever!
The magnets shift to make things worse.
The plastic does a melt down.

Re: TrueFire Timer Rotor Part Source
I guess I have been lucky having run one since 2001 on my ‘13. I have a spare unit and just examined the rotor and I can now understand the risk. I have been thinking about some solutions. The easy one would just be to make some new plastic ones. Does anyone know exactly what type of plastic they were made of?
I will guess perhaps nylon or similar
Perhaps Teflon would be a okay choice as it is very solvent and temperature stable?
If I could get orders for at least 10 pieces I would consider doing a run??

Re: TrueFire Timer Rotor Part Source
If someone is going to produce new rotors, why not machine them out of brass or aluminum?
How many magnets are there? One, two or four? If there are only one or two magnets, the rotor wouldn't need to be circular. For example, if there are two magnets, it could be a "bow-tie" rotor.
Just thinking out loud - not an expert and I have only seen fuzzy pictures on the forum of a TrueFire rotor.

1. Round objects are typically easier to make
2. The magnets are a press fit, so a plastic is MUCH “friendlier” than brass or aluminum without totally changing the design

Re: TrueFire Timer Rotor Part Source
The most difficult part is finding those magnets.
They are and remain very strong.
