Which blades

Advice on blades please

The blades shown in the accompaning pic are both original on an old Dunlite 4 blade genie, 10' dia.

My question is can anybody suggest which may be the better, I use the style on the right on my current unit. As I rebuild the next I am wondering if I should try the second from right.

Perhaps one was for lower wind areas or simply an improvement on design.

Any suggestions appreciated.

regards

Allan

Hello,

I'm sorry I've got no idea, which blades are
the better ones for you.

But I wanted to know the material and the production
method of the blades. They look to be made of aluminum...

The blades are made of sheet metal, they mount on an aluminum spider and have a folded stifener over the spider inside the blade. Blades are spot welded together on the join and bolted to the spider with about 9x1/4" gutter bolts.

Spider can be seen in this pic, this particular blade has probally been made by its previous owner who used pop rivets.
