Odds and ends

A bit of pickup work this evening -- odds and ends that will allow the final assembly of the prop hub and the installation of the prop spars:

I milled off the tops of the stop and load cell contact bolts. The hub can now freely move fore and aft on the roller even under load. Also adjusted all the stops.



I installed the three load cell over-load limit set screws in the thrust plate. These insure we don't deform the load cells

I drilled, tapped and installed the screws in the prop spar 'dog bones' that hold the bearings in place. These bearings are inset into the bones and generally will be pulled into their sockets -- the screws only hold the bearings in place when not under load.

I also sliced the small bronze sleeves that will act as spacers -- holding the spar collars against the bearings but away from the bones. This will allow the spar to rotate freely for pitch adjustment.
