Asked Questions (FAQ)
Why do you not have any actual pictures of the
Because this colorful version was not built. Three square cornered
4' x 8' hover pallets were built and used as industrial heavy lift
units. These were capable of lifting over 3,000 lb. payload, i.e.
used to move the Canair 512 hovercraft along its production path in
the factory. Only one electric Toro leaf blower was used at times
the Canair needed moving. When no one was around, I would sit on these
pallets and push myself around using a rubber tipped pole. (I know,
little things please little minds!)
Why won't the Mini-Lifter work on short grass
Its all a matter of volume flow of air into the cushion. On a perfectly
flat smooth surface like a good quality concrete floor, the actual
air gap beneath the skirt, with a 300 lb. payload, might be less than
1/16 of an inch. If the grass could be completely flattened, then
the Mini-Lifter would still work. What in fact happens is that the
grass can only be partially flattened by the loop skirt. There is
still a matted thickness of grass, probably equivalent to ¼ inch or
more that allows the air to escape. With such an air loss area, the
leaf blower fan can not provide the necessary volume flow to maintain
the pressure and the Mini-Lifter won't lift off the surface.
What can be done to allow the Mini-Lifter to
operate on grass and other surfaces ?
I suppose trading in the leaf blower for a small lawn mower engine
driving a small multi-bladed fan mounted in a bell mouth duct might
do the trick. You have to be careful not to attempt too much of an
upgrade for such a basic vehicle. The next question might be what
if we added an engine and propeller, can it be turned into a self
propelled hovercraft. REMEMBER, this is only a 4' x 8' piece of plywood,
it has no flotation, no hull depth and so on. ACV Designs will shortly
be adding its Hoversled as a plan package. This is designed to be
powered by a lawn mower motor and will allow kids to toboggan down
hills even in the summer.
