Dynon EMS sensors order came last Friday with network hubs backordered. Should ship today. Installed the CHT TC bayonet mounts with red loctite. Fabricated homemade MP port restrictor fitting, drilling out std fitting 5/64" and installing pop rivet, removing its mandrel. Chose to mount MP sensor on the engine side of the firewall, drilling out 2 rivets for nutplates with which to bolt the sensor to the FW. Difficult making dimpled holes for nutplates; one hole was undimpled, but backside of sensor is not uniformly flush so this did not matter. Drilled the sensor holes to 17/64 to give clearance for the bolts to go into the former rivet holes. Pics were taken 4/12/2014. (This entry written 7/17/2016, so quoted hours are accurate.)
