Before Bringing to Space

• Wheels - Tyres are naff. Needs 2x P205/75R15 (6.70x15)
• Fix wheel studs (Ordered - Wheel Nuts + Studs - £44.12)
• Driver - Someone is lined up
  • The trailer is >750kg so you need a B+E license or a pre 1997 license

After Bringing to Space

• Seals need replacing. £165 + vat + delivery for a complete set of seals, O-rings, and grease.

• Stripping
• Rustproofing/welding
• Trailer electrics sorted out
  • Replace the raising crank with a motor?
  • Replace the petrol engine with an electric one?
• Pull cord for the engine
• Painting (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.
