Just curious about the RB cable excavator with the cast steel track frame, behind the donor engine there, That,s a collector's item for someone.
I am still harboring an operational 19RB dragline in my yard at present.

I don't know anything about the RB excavator, and I don't know if it is complete, I haven't seen it as the doner engine was delivered to me by one of the Museum volunteers.

Graham came down today so we pulled the liner. it is in good condition and can be bored out to accept the larger piston. Graham, a member here, took that, the head and valves, injector, and the piston home with him and will recondition those parts.

Now I will start on the base so it can be mounted and I can assemble it on the base, and make the water and fuel tanks. I have cleaned a lot of it up and it is starting to look like I am making progress.

Graham has made a liner pulling jig using a "Porter Power" so getting the liner out was a simple and quick operation.

This project was never going to be easy and it has taken a turn for the worst. The 8 hp piston turned out to be seriously cracked and unusable. It wasn't until it was cleaned up that this was found.

Graham has a friend who is a retired pattern maker. He now has the piston and is making a pattern. Graham also has a basket case CF that needs a new piston so we will have two made and as the originals were alloy, the new ones will be as well. We will share the cost which will be more than the engine is worth. The hobby for me is about bringing engines back to life.

I am now going to go ahead to make the base and start to assemble what I can while waiting for the new piston.

Combustor, If you see this you are right, that it is a RB dragline it has been refitted with a Caterpillar engine and it is still operational. the Plains museum is setting it up as a working display. I was there the other day.

Progress is slow on the R&T. The pattern maker has suffered a stroke so another of Graham's contacts has made the pattern, so hopefully we will soon have a piston.

Default RB dragline (off topic)

Hello Mervyn,
Thanks for satisfying my curiosity about the old RB dragline in your pic. Glad to see that another one is being preserved as a working display. Hope you can still find an operator. Not many of us left on the planet nowadays. Trying to find a home for my Gardner powered 19-RB. Kind regards,
Combustor.

One Of the operators who originally drove it is a member of the Plains Museum. No doubt he will teach others.
