I didn't think it was too bad! I haven't examined it very closely yet, I'll find out when I do!

I wonder if you could do something with the pulley that drives the original mechanical counter? Perhaps glue a slotted disc to it?

Yes, either that or the underside of the brake drum.

Although there are some really good pictures in the manual, it's hard to get a sense of how much space there is when it's all assembled.

There's very little space between the motor and the chassis, not enough to fit in an encoder. From the top of the chassis to the underside of the brake drum is 1/2 an inch and to the underside of the top plate is about 3/4 of an inch. There would be enough space to fit the encoder.

Presume you'll pick up the heater winding as a power supply?

Probably, I hadn't given a great deal of thought to that yet but there are three low voltage secondary windings from which I can choose: 24V, 22V and 12.6V. I think it will probably have to be the rectified 12.6V, the current drain isn't going to be very high so it shouldn't affect it adversely.
Regards,
Dave.
