I made this engine out of three donor engines and a tank from CI. I took the ridge off a TD spinner with a drill and some wet or dry.
The cylinder is #1, two intake ports with SPI, all parts were new or like new. Came out pretty nice. Beer Cheers

Where did you get the big head needle? It put the finish on it. I've always liked the thin wall cylinder, stunt tank, and large needle look.

Cool

Cylinder may look good, but without wrench reliefs, they are a pain....

I use a 2" long "sleeve" of 3/4" i.d. garden or heater hose to grip those cylinders with slip-joint pliers.

Or you could use the standard Cox wrench in the exhaust ports as designed.  Very Happy 

You have to make sure you have a good bite as it's somewhat easy to turn in a burr.

I got the idea from here on this. I believe it was Mudhen who said it, but not positive. Get a plastic bag, ziplock etc., and fold it in half, and then half again. Them fold it in half once more but sliding the cylinder between the two halves. Now use the cox wrench as intended. The bag will take up some of the slop in the wrench as well as act like a cushion. Will leave little to no marks at all on a cylinder.

My tool of choice is this heat sink, wrap layers of tape around the cylinder then clamp on the sink. The cylinder needs to be soaked, I'm worried too much will put a twist the cylinder.
I also found tape on the wrench for the exhaust ports works well, no bur.
I used the heat sink to do 99 engines,

If I ever resort to using the exhaust port tool on the wrench, I trap it horizontally in the vice, so it's clamping against the wrench's narrow sides. Then slide the engine into place and turn it. The vice should keep the wrench forks from spreading and causing a burr.

If I never laid eyes on a RR-1, yours  
would still be a pretty slick looking engine.
Great  job on the spinner, Doug, looks like
the real deal. Good port orientation on the
cylinder too.

Looks great! From a distance or when up in the air, people would think you have a real one.

It doesn't have to have ribs and fins to be real, this is a really early one from Mud's collection.

1956. It was the initial issue RR-1, then there was a design change to the natural aluminum case with fins and the tank with fins.

The RR-1 didn't come out until half way into '56 and the initial version was produced for only a few months, making it the hardest to find Thimble-Drome engine made, many "experts" don't even acknowledge its existence.
