bought a cheap halogen heater from BM bargains for £8 does a great job of warming up the paint, and the hub...
some old plasterboard i had knocking around in the shed made a nice little booth and keeps the fumes going up the chimney of the extractor.
I initially give the hub a real good wash in the sink with washing up liquid, and then baked it in the oven to get it up to temperature.. applied a few coats of etch primer, and going to give it 24 hrs to harden up a bit, then on to flatting it back a bit next coat of high build and a gloss topcoat.. should be a few days...
my old monitor turntable was great for turning the hub around to get to the other side.. the disk threaded holes blocked up with 6 screws, 3 downwards, and the other 3 at 120 degrees upwards apart to rest the hub on.... the old bearings were kept in to avoid getting too much paint on the bearing surfaces...
anyway heres the pics...
