    How to build a pretty simple Hovercraft.


    Here are some directions on how I built my homemade hovercraft.


    Supplies


    1-piece of 3/8 plywood. This was the thinnest I could get. If you can find something thinner or lighter use it.


    Some 2x3's


    Some Marine grade vinyl for the skirt. I got this at a local fabric store for under $20.00.


    A seat. I used a milk crate.


    Chicken wire. Home depot. 1/4" holes.


    Two small engines:


    For the lift I used my backpack leaf blower. As is unmodified. I just took the tube off.


    For propulsion I used a 2-cycle snowblower engine. I think it's about 2.5 H.P.


    A model airplane prop. I got it off Ebay for $12.00 with shipping. It's 22" with 10 pitch. You will have to experiment with this. You want your engine to run at full RPM at full throttle. If the engine is running too fast you want a higher pitch or longer prop. If the RPM's are too low you need a lower pitch or shorter prop.

    Ed, how well did it work? I was surprised to hear a leaf blower would create enough lift.

    Pretty good, If you gone down to the bottom of the web page that I gave the link too you can see a video of the guy using it.
