A near perfect set of sails and a vane for a Dempster 12A came along so now i feel i should find a mill to put them on. My question is, how do i identify a 12A? What is the difference between a 12 and a 12A?

As far as I know, it will fit either a Dempster #12 or a 12-A. As long as it's 8 foot head.

The answer to your question is, under the snout it will either say 8 ft #12, or it will say 8 ft 12A. 6 footers don't have that under the snout.

So theres no mechanical difference between a 12 and a 12A?

Oh yes, it's a whole different animal. But the wheel is not gender specific. I think the tail is changeable also.

Any pictures of what that looks like?

Mike,

Here is a few photos of 8’ Dempster #12. This one was on a 3 legged tower that folded up, like the wheel folded up.

I don’t know much about Dempsters other than I dislike working on one and Dempster’s engineers seem to have gotten paid by the parts/variations they designed. Someone more knowledgeable can answer the 12A v 12 question.

Oi oi! What a mess! Take some skill to get that wheel back round again..

Duct tape and glue. No problem!!

Is this normal? Are the holes supposed to be slotted or are they worn?

My guess , WORN OUT !
