Re: Thimble Drome Champion
Out of the cars I own /owned, the Funny Cars as well as the worm gear driven cars like the Dune Buggy etc.. were the only ones with the beveled crank. The rest of them had / have splined cranks but all of them had / have the large journal crankcase.crankbndr wrote:I think these and some other car engine had a large journal crank and case, the flywheel is pressed on the splined crank.
I didn't tear it down that far to know for sure, I have other car engines with large crank and the crankcase goose neck is much larger than normal and the front of the crank is angled instead of splined
to fit on a angled flywheel hole. I'll see if I can find some pics of those.
Also, here are some pics of the crankcase and beveled crank.

Re: Thimble Drome Champion
To paint the front axle holders I tried Dupli-color adhesion promoter for plastic and it worked very well right over the chrome.
First the adhesion promoter then light primer coat then color then clear, they came out nice. Not fuel proof though. I also used it to paint the seat black.
I also found a like new set of front wheels and tires.

Re: Thimble Drome Champion
Ive wanted an early issue Cox Prop rod for a while now, it was the first Cox toy I had and we ran the crap out of in the street.
This one came along so I got it, it came with a new red nacelle and the Bee is like new. When I broke it down found out the red nacelle is for a later issue Rod.
The blue one is mounted differently and glued on, wow, going to have to remove the blue one by cutting, grinding, sanding, filing OH MY!
The two nacelles look to be the same shape, the red mount needs a red tank Space Bug Jr to go with it.

Yikes! That is going to be a beauty of a prop-rod.
That red nacelle is going to look sweet.
Nice score.
Keep us posted on the progress.

Ian must have seen your post because he sent me his methods for restoring the Thimble Drome cast cases, I think he is a master at engine restoration and using his advice will work on the Space Bug Jr. next. Shout out of thanks to Ian!!

Re: Thimble Drome Champion
I got the Space bug Jr. cleaned and mounted up, using Ians advice and methods I still could not reproduce his results on the engine.
The new nacelle came with factory screws, good thing as Ive had trouble in the past trying to use different screws on Cox models.
The body is done, now to work on the pan.

Re: Thimble Drome Champion
The prop I have is a 5/3, I forgot the maker name but the logo on the blade is a K with a sunburst and on the other is a R with a sunburst.
They came with early Cox engines, I need a white 6/3 for the Prop Rod. Got my eye out for one on eBay. There is a guy that repros the white one.
On closer look both logos are same K, from Marks site the maker is Kay-Sun

Re: Thimble Drome Champion
Man that is looking real nice.
I have never seen Goof Off or Novus products here although we have a Novus windscreen replacement and repair company.
Can you tell me who makes those products and I'll see if I can hunt some down. Those and your meticulous work sure do a nice job

Re: Thimble Drome Champion
After seeing your question I did a little digging, the bottle of Goof Off 2 I have is about eight years old and no longer available (I should have bought a case).
The closest I can find that is safe on plastic is Goof Off Heavy Duty, it's a different formula and looks like it's hard to ship out of the US. The old formula was combustable and would kill you if you live in California.

Novus is sold on eBay and Amazon and should have less shipping problems
