Would anybody happen to have a link for a plan for a five bladed woodchopper/hammer whirligig that they would give up? I've searched relentlessly for 2 days. I'd be willing to buy it if it was downloadable. Why it has to be 5 bladed is beyond me, it's for my dad. He has no computer and don't want one. Many thanks if anyone could be of help.

Tim, have you considered buying one of the plans that's out there for a
4 bladed version then modifying it for a 5 blade setup? That shouldn't be too difficult to do, just a matter of spacing the vanes equally on the wheel.Martie in Mo
Interesting about the five blades. Most ceiling fans have five blades to reduce resonant vibration - doubtful that would be a problem with a whirligig. I'd be interested to find out your Dad's reasoning. The two things that come to mind are esthetics or maybe he thinks that the whirligig would be less likely to get hung up in a dead spot (though I don't think that's true).
Here're some five bladed whirligigs (no plans, sorry): First one has five wood blades inserted in a hub - probably the easiest way to do wood blades.

one has a five bladed metal prop, which is probably the easiest way to do the prop.

You might want to check your library. If your library system hasn't info do a search within the library system and you'll likely be able to get a book from another library system.
