Hi all,
Once I decided to build a Keppe motor per the Keppe Motor Manual I realized I dreaded building the transformer support and also winding the wire. First I selected a fabrication method for the plastic transformer support. I decided to just cut up a bunch of pieces and glue them together. Since there's no way I could wind this thing without losing count of the # of turns, I built a winding fixture with a counter on it. The transformer support is made of 1/8" thick white ABS sheet. It is assembled using a hot glue gun and Super Glue. I made an assembly mandrel to facilitate assembly of the plastic pieces.
The only reason I posted these construction details is that the manual only points to a picture of a plastic transformer support but gives no source for it. So to ease any frustration for any other Keppe Motor replicators that bought the manual I have presented one way to make it from scratch.
Here are some pictures of that effort.
#1 is the support center assembled on a mandrel. Pieces were held in place with rubber bands.

#2 is an end "C" flange and center getting ready for assembly

#3 is one end "C" flange attached to center on assembly mandrel

#4 is both end "C" flanges attached to the center

#5 is the complete main support. "C" flanges are closed with a short piece between the "C" and a doubler

#6 is the fully completed transformer support with primary and secondary partitions.

#7 is the winding fixture showing the counter and arm on the winding mandrel and crank

#8 shows the finished transformer support on the winding fixture and wire spool ready for winding wire
