28th September


The start of the experimental horizontal windvane.  I have some fiberglass tubes that telescope and going to use them as the support.  I wrapped some epoxy saturated glass (after sanding and acetone prep) over the inner tube which will be on the top. (just the end where the stainless steel homemade hinge will be bolted on) to make it a bit stronger.

Also cut some 316 stainless to make support brackets. and bent them for the 17.5 degree angle.  In all my research it seems that between 15 and 20 degrees is the best angle so I picked the middle.

Im going to make the tube support and hinge bracket before actual vane hinge so I can get the exact dimensions. 

Fired up the antique lathe to make the bearings.



First go was with some mystery material which I thought was Delrin but I guess it was some type of nylon or acrylic.  Not easy to machine and very messy.  

I then turned down a big diameter piece of Annealed POM (Delrin) which was totally different.  A big waste of material but it is all I have.  What a difference!  Nice and clean and smooth.  I am no expert in lathe work , just what I see on Youtube and my lathe was salvaged from the Ark.

Delrin on the left and mystery material on the right.  Only need 2 bearings but made 3 of each so have spares. I think the mystery material should go in the rubbish bin.

I will post  an easier to understand  description of what Im trying to achieve when more bits are made.

Enjoy your weekend!
