Great video and upgrade/restore Bruce, (as per usual)
  Your D12 pulls that baker fan with some authority!
   Your video had the bit about the loop style rod, I went and checked my ebay ad as my D12 has not arrived from Germany yet. Mine will be the newer style flat rod. In my brain your loop rod holds precision for a longer life, can you still slip that loop style off the crank pin and pull the piston/rod assembly out to Lube by compress the steam chest spring? In my head the wider bearing may resist the rocking motion needed, but it may still work fine?
