Steam Spider II project took the opposite approach to Steam Spider I.
Joe and I decided to Start simple, but make a flexible design to refine and build on
top of. The idea is to use an affordable steam engine, Wilesco D14
(the same one used in the Steam Walker) and produce them as kits, or pre assembled for sale.
Construction should be pretty simple, similar to erector sets – no machining required, only basic tools.
There are many plans for upgrades and add ons on the Steam Spider II, but initially the
Steam Spider II will just be an 8 legged walking Spider, capable of walking forward or reverse,
with a built in whistle. Design and prototyping is in progress, and hopefully soon will
have a solid design that is easy to build, as well as simple and fun to run.
Initial Steam Spider II sketches. Considering wide or narrow chassis
Steam Spider II Sketch. Original Wilesco firebox is redesigned
The “Woody” version. Wood lagging would help insulate from heat lost.
Firebox need to be sealed on top to not catch the wood on fire 🙂
Tubes on the topside of the firebox is designed for ventilation.
Joe’s final Steam Spider drawing in 3D. Holly gears! They are needed as these engines
are very low powered, and requires a lot of gearing down.
