Mediocre by standards here, but it's a start.

Not set out to be "correct" or duplicate any existing Cox engine.  Just an accumulation of parts on hand and a new EX Engines crankshaft and glow head.  

Postage Stamp back plate, Exhaust deflector, Grooved cylinder, Milar reed, Straight nose case, Brass hexagon Prop washer, and replacement EX Engines Crank shaft and Glow head.

Funny, I could not find anything about the pistons in the Cox Engines Handbook, nothing in the index either.  But there have been discussions here about "early and late" pistons.  One being a three piece.

But these are different.  I used the relieved connecting rod in this engine.

Bob,

the very first 3-piece pistons are discussed on Wikipedia, here:

https://en.wikipedia.org/wiki/Cox_model_engine#Pistons

Yours are old-stock, post 1957 pistons (but not the 3-piece unless they have a retainer clip inside) Later pistons did not have the balljoint cap swaged in the piston top, but machined from the piston body itself...this difference is visible on the smooth top of later pistons:

My first Franken Cox Newpis10

In addition, the oiling hole in the large end of the conrod was added on the 1st production runs of TD049-s. I have one NIB TD049 that has the oiling hole...COX abandoned the oiling hole in later conrods, maybe from mid 1960-s...the conrod material in these old engines is a kind of white metal, different from later conrods.


PS.: can someone explain to a non-native speaker what the adjective "franken" means? I was trying to look it up in concise English dictionaries but to no avail....

Then this engine should be a bloodsucker with long fangs in its mouth, wandering in the dense forests and returning to his castle to feed on a new Babe (Bee) in Transilvania (that used to belong to my country Hungary before 1919)?

Andras, I think you are confusing Frankenstein with Dracula.

Here is another famous Transilvanian: Dr Frank N Furter lol!

Yes, but unlike Dr Frankenstein, Dr Furter did create something close to perfection (if you are open minded enough Wink )

Yeah, Old Frank N. Stein was made up from parts, a body here, a brain there.  Just like my model engine. Lot's of Franken's,  MG's, Corvettes, and other mechanical things.

Good information Andras, I just don't understand why it (the piston) wasn't included in the book.

Franken # 2 coming up.

Didn't we lose her when she drove a Thunderbird off a cliff.  Wouldn't miss Susan, but I sure would miss Geena,

Any opinions as to why that crank case is marked in such a strange way?
