Stop burning my fingers

The blower control wheel on my coal fired loco get's hot, any ideas what I can cover or paint over it to stop my fingers getting toasted?

Small piece of silicone tubing works.

I did think of that but I want the whole wheel insulated.

I put some heat shrink sleeving on the controls of my Regner engines. Seems to work or
my finger tips are getting heat resistant.

I did this in the end and allows finer control with less burning but would be nice to cover the whole wheel somehow:

Tom,
I wonder if you could 'paint' the whole wheel with clear silicone sealer? Not sure if it would stand the heat, but might just keep the bare metal from your delicate parts?

Locally, the electronics shops like Jaycar sell a liquid plastisol called 'liquid insulating tape' in a choice of black or red. Basically a thick paint, that comes in either a 28g tube or a 118ml can. I would think something similar is available in the UK.

A cheaper alternative would be painting the wheel with many coats of gloss enamel until the layer is reasonably thick and see how that goes.
Alternatively, looking at the wheel design you could probably make a simple tool from a couple of small nails in the end of a piece of wooden dowel, that would fit the wheel openings and adjust the valve if it isn't too tight. Same principle as the tool Roundhouse sell for adjusting safety valves. Several inches of wooden handle will be a vastly better insulator than any coating you could paint on the valve wheel.
