I have seen the toy called “Puddle Jumper.” It is also called by other names, prop toy, palm helicopter. It’s the toy that is a length of 3/8 dowel with a simple 2 blade prop on top. You launch it by spinning it in your palms, and then it takes off. I know it is a simple, very low cost toy, but I am intrigued. I want to try and make some. I think that there must be some kind of jig that can be used to cut the props either on a router table, or table saw at the right angles. Has anyone ever made these? Or does anyone know of some kind of jig that will cut these?

The simplest way to do this would be to go to a hobby/model shop and buy ready made propellers; either wood or plastic. Then attach these to small dowels. The ready made propellers will be more consistent in pitch and balance and will perform better. However, I’m sure you could make a jig to hold a piece of straight grained wood at an angle corresponding to the blade pitch and use your band saw to cut each blade. You could also start with a circular wood “button” (make with a plug cutter or cut from a dowel). Cut a slot on opposite sides and glue a flat blade into each notch. A forth way would be to start with two thin wood blades of the same size and notch and glue them end to end at angles corresponding to the pitch you want. Then drill a perpendicular hole through the glued joint for the dowel. Epoxy would be good for this.

Have your say...
