I used an automobile airfile for fine sanding. I replaced the base of the airfile with a board.   I sanded a length of closed cell foam to the profile I needed and attached it to the board with 3M #77 spray glue.  I next glued #36 grit sand paper to the profiled closed cell foam. Believe it or not #36 grit leaves a smooth finish.

The back view of the fixture. This is the rough cut. Sanding comes next

Rube goldburg fixture for cutting the concave portion of the propeller. A 7" saw blade attached to a 4" grinder attached to a right angled bracket. Set the saw blade to the height of the profile of your cut. You will SLOWLY slide the board under the blade. Make sure the fixture is solid.  It took two setups for my particular curve.

Hi Ralph and welcome to the forum.  I appreciate you taking the time to sign up and share pictures of your project.  There are many of us that share your passion.  I'm glad the website has been of use to you.  I don't believe Wincharger soldered the brushes but I can't say I've seen every variation the factory made.  Even if they used the lower melt temp solder, it would be easy to overheat and anneal the thin copper strap and lose the cold work that gives it "spring." Maybe someone out there has one like yours.  Some pre-REA wind chargers, like Jacobs did solder or braze but they also had thicker copper straps.  Below is a pic of the typical swaged 6V Wincharger brush that I've encountered.  Even the 32V and 110V Winchargers had swaged brushes although I have seen an early 32V that used a screw to attach the brush to the copper strap.
Looking forward to seeing pics of your finished project.

Slip ring brush holders.

Looks like they were soldered in.  1/4" x 3/8"

Hi, Found a Model 39 Wincharger at an antique store in Nebraska last month. I had never seen one before. I spent the next week or so reading about them.  Quite an education. I talked to Winchester Mike about what I had.
I plan on restoring it and putting it on the peak of the garage and using the 6v power to light Cree LED lights to illuminate the unit. I found a 2" x 6" x 6' at the hardwood lumber yard yesterday and cherry picked a long grain tight grain piece of Douglas Fir. Somewhere in there is a propeller.  On line I found a Gottingen 222 airfoil shape that is 4" x 1". I plan to use that as the shape for my propeller unless this forum tells me otherwise. 
It appears the unit was painted with a silver Zinc paint (cold Galvanizing) sometime ago which has saved it.  My plan is to spray it again with the zinc paint and spray Krylon as the finish coat. Any comments, corrections, or other tidbits are welcome. Thank You, Ralph
