O.K.,
Threw the top on her today and then bench tested.
I highly recommend you “bench test” your work before sealing up the case halves and reassembling the brake mechanism.
Here I just loosely fitted the solenoid pack and put the top on (without silicone) to test.
Everything went well….so I buttoned it up with sealant and installed the solenoid pack for good.
All I lack now is the brake mechanism (saved the fun part for last).
