Revision as of 14:33, 18 February 2011
A hybrid steam engine/steamroller/rollerskate built around a victorian style boot.
Features
- Mill-style steam engine
- Boiler and furnace live inside the boot, with a hinged grille on the heel providing access to the furnace.
- Furnace fuelled by hexamine tablet
- Furnace and boiler made of two tin cans brazed together.
- If possible, enclose assembly in a slightly larger can with rockwool nested between the two to protect the boot from the heat. If there's no room for a larger can, just stuff the boot with rockwool.
- For combined thermal, protective and flame-retardant properties, nomex racing socks might be ideal (and cheap) insulation.
- Combine water inlet with close-fitted weighted cap as safety valve?
- Moving parts live outside the boot.
- Front wheel will be a single roller, connected by forks to the chassis.
- Ideally would attach the fork to chassis with a skate-style "truck".
- Failing that, allow the forks to turn freely and feed a central spoke through the upper of the boot to a steering wheel.
- Back wheels would be fixed to a central shaft and driven by the mill.
- Add a whistle (such as http://www.forest-classics.co.uk/std_whistle.htm) which can be activated by pulling on laces?
Progress
I've ordered a pair of suitably victorianesque boots from eBay that I think will have enough room for a boiler/furnace based on two small Carnation condensed milk cans.
I've also picked a likely engine design: http://start-model-engineering.co.uk/category/elmers-32/ (only upside down)
Ordered a pair of (hopefully) suitable boots:
