     Working a Falcon can into a mini-C type can the other day, I had everything all finished except cutting it to length...and I cut to the wrong line. :dash2:   Sooo, into the garbage it went and I milled-up a another one.  This time I measured twice before cutting once. :blush:   Anywho, NOW the can is done, magnets installed and bearing set.  The JK Hawk end bell (me likey) got trimmed on the radius sides to fit snug, a fresh oilite from Bill Bugenis that I keyed-in after drilling the four itty-bitty holes around the bushing collar, and a set of Pro Slot C-motor hardware.

We have B-cans, C-cans and D-cans. Now we have the "H-can"  

 

Nice work John. When will these be available from distributors?  :)

Honestly, I think that something like this would be appreciated by builders and racers.  The tooling is already half-way "there", the back end of the can allows for better cooling than a closed can, but is also a little stronger than the really soft/bendable bearing strap on the mini-cans.  Having said all that, it won't happen in a million years.  :)

Armature is done and ready for grind/balance.  A reverse-wound #28awg on a 5 layer coil...45/28.  "This motor will kill"  :)

Hi Paul,

It's kind of difficult to describe Paul, at least how to accomplish it. but simply put, you wind from the outside of the stack towards the com.  That means, the wind is good for odd-numbered coil layers...3, 5, 7, when it's more normal to have even-numbered coil layers, 4, 6.  This avoids the problem of finishing at the outside of the layers, instead of near the com where you would want to finish.  Absent a video or in-person demonstration, that's about the best I can do!
