I'm looking to restore a weather vane that was made 30 years ago.

It's of a plane which has a hand carved propeller, it looks like the
blades are at 90 degrees to one another. Sadly the person who carved
is no longer about to ask how he made it.

So what is the easiest way to mark out and make a simple propeller, without
the blades twisting (if that makes sense!)

Thanks.
 
All depends how you want it to look! Easiest of all would be a square block for the centre, with slots cut in each side at about 45 degrees to the main axis to take flat hardwood or well painted plywood, blades. You might get away with just glueing the blades in with waterproof glue, but would be better to pin them through the block. Used to see lots of examples like that in allotments and gardens.

Beyond that, you'd be into woodcarving. Or if you just want practical, find an axial flow fan from a scrappy and use that!
 
I think I'll use a single block of wood and hack it about a bit.

Depending upon how it goes, I may even post some pics!
 
Take a square section length of wood and carve off the opposite corners. I would post a photo of a previous example if photobucket hadn't gone all money hungry :roll:
 
Cheers for the link I may go for 2 blades using the hack around method.

Then may try a 3 blade version!
