Work Required
(This is in some sort of vague order)
- Strip existing paint and rust
- Rustproofing
- Replace all seals and serviceable components
- £165 + vat + delivery for a complete set of seals, O-rings, and grease. Need to provide measurements to Clark.
- Painting with a suitable exterior grade paint
- http://www.hammerite.co.uk/products/direct_to_rust_metal_paint_smooth_finish.jsp - Hackspace blue!
- The original colour was Caterpillar Yellow BS G88/0668. Might be nice to get it in original condition.
- Welding/fabricating replacement parts where required, i.e. wheelarches, reflector arms
- Service engine, pullcord needs replacing
Paint Stripping
There is some Nitromore in the engine compartment and some rubber gloves in Velyks's memberbox. Directions for use:
- Pour amount into metal bucket
- Dab on a thick layer over painted surface so it's all covered
- Leave for 40 mins
- Use scrapers to scrape paint off
- Clean brush and bucket when you're done
Try and work from the back towards the front.
ALWAYS WEAR THE SAFETY GLOVES AND CLEAN OFF ANY GUNK YOU GET ON YOUR SKIN. THIS SHIT IS NASTY
Future projects
- Replace raising crank with electric motor?
- Electric start compressor engine?
- Replace petrol engine with electric motor?
