Hi folks, something I've been working on for the past few weeks.
Miniature steam powered pretzel display stand.
it stands 11 7/8" tall @ the top of the pretzel, weighs 2 lbs , is 4 1/4" square, has a capacity of 48 pretzels & is powered by an onboard Jensen #85 steam engine heavily messaged & with roller ball bearings, it is a worm drive gear system also with 2 roller ball bearings in the axle. there are 3 roller bearings in the rotisserie post mounts & has 3 tiers of pretzel holders with 4 racks on each tier (all brass, all adjustable), the case is solid Indiana Oak w/ polycarbonate clear sheet for the windows. the SPS signage was custom made by Kramer creations. the pretzel on top was handmade by me out of modeling clay, hardened & painted & drilled & tapped to screw onto the Brass rod. it will run on as low as 2psi (& getting better all the time) I can remove the belt and run off of any steam engine of 7/16" bore or larger.
