I got a couple of hours work in today. As I am still waiting for engine and GB mountings to come, I am getting bits and bobs refurbed. Today it was the turn of the heater fan. For the heater box, both ones I had were so badly rusted, I bought a new one from the UK on eBay. It had been galvanised. I t-washed it and got it powder coated. Try rusting now ya wee bampot.. notice that it’s a RHD box but for this part, you can simply turn the radiator matrix round and put the pipes out the other side (after making holes)

Next the turn of the fan unit. Unfortunately, this is ‘handed’ and cannot be turned.

The RHD one was toast. Luckily, the LHD one was rusty but not perforated. Sandblast and powder coat later, it’s looking pretty sharp. Both motors were working but noisy. I checked and both are reversible by simply reversing polarity. I pulled the motors apart and made one with the best bits of the 2. Watch when pulling apart because the spindle shaft sticks on the internal bushing of the motor and in the first case, pulled it out of its spring washer/tabbed housing. Impossible to get it back in. Lucky I had a spare...

etch primed and some black paint (aérosols are handy for small jobs as they save waste and washing the spray gun). To put it all back together, it’s all imperial and I don’t have such small sizes so tapped it all to 5mm which more or less does it. Can anyone recommend a place where I can get a large selection of zinc plated imperial nuts, bolts and washers? The constant grubbing around for the right imperial ironmongery which is inevitably used and rusty- is frustrating and I am annoyed about having to put rusty bits on a clean project. I love some if these projects on instagram with every but, bolt and washer dichromated. I wish I was that organised...
Anyway, here is the finished article - crowned with 2 rusty nylock nuts which had to remain imperial and are about 4.8mm. Any ideas what size that would be?

Lastly, note that the hamster wheel fan is handed. The orientation of the blades depends on drive side. They seem to harden and disintegrate with age. The RHD one was already vaporises. The LHD one crumbled in my hand when removing. There is a bloke on eBay in the UK doing new ones and they seem to be a bit stockier that the originals. Note that the LHD ones are only 5 cm wide against the 7cm for the RHD ones. So a bit less efficient but who cares, the weather’s better here.

Blows like a hurricane, a little noisy on full tilt but I think thats original. Not bad all in all and makes up for yesterday...!
