RE: Rusty engine salvage?
ORIGINAL: cutaway ORIGINAL: Ram Jet When I get the guts and technical confirmation, I'm going to leave my castor girfriend in the dust. Sorry all you old farts. Get your heads out of the 30s and 40s. I've been around this game a long time. Castor is the difference between getting 20 hours out of an engine or 300 hours. I still have an open mind. I would miss the smell of burned castor. A funny story. I recently bought my start in this hobby. I bought a Thimble Drome P-40 .049. The guy wrapped the dickens out of it for shipping. He must have had $10.00 worth of USPS tape on it. It was wrapped in a thin foam cocoon, and then wrapped in tissue. When I broke through the outer wrapping and got to the tissue I cought the wonderful aroma of castor. Probably 50 years old. I can't get the stink out my tool shed where I break in my engines. Stink smink - it's freakin' perfume to me. Bill |

This was recommended to me recently and it works very well. It has a gel consistency and is mildly irritating to skin. It is a no-scrub cleaner for baked-on, burnt-on greasy dishes. You can buy it at most stores (I got mine at Wally world). I spray it on and wait about 10 or 15 minutes then gently rub with a stiff bristle brush. When you rinse it off with water, it turns to soap and really works. I've used it on model engines and most recently on automotive carburetors. There's very little odor and so far I have not had to use gloves. I've done all my parts in a tupperware bowl in the bathroom sink. For all you married guys, just act like you want to help your wife out in the kitchen, and she'll go buy it for you!

I'm going to try it. Other members have recommended it also. Thanks, Bill |

I'd like to add, that the Evap-O-Rust batting average so far is 1.000 I've salvage 3 previously hopeless engines with this stuff.
A Fox .15 (schnurle) A Fox Stunt .35 (old early 50's version, but not oldest sandcast model) A Fox Mk4 Combat Special None of these engines were disassembled or even had the backplate off. Just unscrewed the plug and dunked'em in as-is. |

What's really wrong with castor oil? It is a renewable resource (not fossil fuel based) with good lubrication properties. For most engines that are not ringed and ball bearing it is a better lubricant than any synthetic available at the same price per gallon. Some of the arguements against it sound very much like the arguement a friend gave me for why he was buying a Sony Betamax... (which I gladly admitted was a better technology for some uses same as synthetic oils). I am willing to bet that we will still be using castor oil in model fuel 50 years from now... in fact may be using more of it as things like model fuel can be viewed as rediculous use for limited resources.

The little steel wire clips that retain the wrist pin will rust, lose their tension and "become one with" the space between the side of the piston and the liner. Rust is also a very good lapping compound, so any traces will promote rapid wear. Castor is a very effective rust inhibitor.
BTW........ No comment on the comparison made between a Fox .35 stunt engine and a formula one Ferrari engine...... |
RE: Rusty engine salvage?
Ahh why not CP, I read that whole second page just to see some one pounce on the absurdity of such a comparison.
Now if he had compared that old McCoy .19 I used to have way back when, and the space shuttle solid rocket boosters... Well then he would have had a valid point.. |
