Today has been a laid back kind of day. I made the oil filler tube and Loctited it into place, made the oil filler cap and right now it is mounted on a short piece of 3/8" shaft so I can cross drill it. I also made up the distributor ignition adapter plate and made up both exhaust pipes. That's not a lot, but somehow it has filled up most of my day.

Another family time work stoppage coming up, so it will still be awhile yet.

Hello Don,
the motor has a 0.55kW rating.

It was sold on ebay:

Got in a little time on the Ruston model today, made up the pivot brackets that will hold the bottom end of the main boom from some stainless flat stock:

These will have a single axle running from one side to the other, and the two brackets will be silver soldered to a wide plate that can be bolted onto the front of the cab floor. The slots that the end of the boom sits in are wide enough so that the boom can pivot up nearly vertical, and down below horizontal. The second smaller hole is for another axle that will hold guide pulleys for the crowd cables. On the real machine, the larger axle had a chain driven pair of cable drums to drive the crowd cables directly. The chain went back up inside the cab to another set of sprockets and clutches. For this model, I'll route the cables back to one of the electric gearmotors.

SteamR:

I just watched your video.

It may look like some kind of medieval torture device, but it did a fantastic job. The sewing machine motor looks similar to the servo motor I put on my drill press - just smaller. What was the kilowatt rating of your motor? I have a couple of smaller machines that I would like to re-motor with a servo motor, but can't seem to find any motors smaller than 0.5-0.75KW.

After the fun field trip out to the steam shovel, I got the bearings for the chain drum sections turned/bored out. These are not high speed or long-running items, so I used some brass, not bronze. They are a push fit into the flanges, and run free on the main shaft.

A view of everything test assembled:

Next step will be to do the final install of the chain guide rails and lower pipes, which got trimmed to length the other day. They need to be drilled/tapped for some screws through the base, and a large hole inside each pipe cut through the base plate for the chain to go through - the deck below would have a large room that the chain would collect in as it was hauled in as the anchor was raised. These rails would keep the chain from getting stuck on the drum and wrapping around past the pipe opening.
