RE: Testing the new NV (Norvel) .40 size (6.5cc) gasoline glow engine
[quote]ORIGINAL: hllywdb The main issue with phamacy grade castor is not what is ADDED to it, its what has been REMOVED. Medical castor is highly purified, which while making it a great laxative, removes chemicals that are good for lubricating engines. Technical or lubricating castor does not have to meet medical standards and thus is great for lubricating engines. What the engine needs is good lubricating castor. This would come more from a petroleum company than from a medical supply company. [/quote] don't know where you got that from, BP castor is about as good as castor gets. ONLY difference is that it is tested and certified to be free of trace amounts of poison and other impurities...of course it costs more because of this but it is often easier to obtain from the chem supply companies

RE: G-38 Conversion to CM-6 Plug?
another option is to use a 5/8" hex taper seat plug like the NGK BMR6F. by cutting off the threaded post and using a small conical spring in the cap to make contact with it you will come out shorter than a CM-6 with adapter AND it is a resistor plug.

RE: Resistor Size In Plug Cap???
the value of the resistor depends on the ignition and not the engine so just use what came in your new CM-6 cap kit. also, the 1/4" cap being "non resistor" probably refers to the fact that no 1/4" plugs have a built in resistor so there should be one inside the cap. the problem with film resistors is how they're made. basically a ceramic core is coated with a thin carbon film and then the film has a spiral groove cut into it to effectively increase the length of the resistive element...this creates a coil and a coil is an inductor and i guess that does all kinds of funny stuff when zapped with 20KV. they also just don't stand up to that voltage either.. the old carbon composition resistors are really only rated for something like 600 volts but because they hold up well to high voltage spikes they work anyways...

RE: Resistor Size In Plug Cap???
pay attention to the type of resistor that's in there as well. it's a called a "carbon composition" resistor and even though they were the standard many decades ago they are harder to find these days as they only get used where modern carbon film resistors are bound to cause problems....like in our ignitions. digikey has them, just look for "carbon composition" in the resistor section.

RE: Getting Back Into It - Workshop Ideas
i just recently went from around 7,000 square feet of shop space down to 800 so i'm learning the art of shelf building and filling the dumpster with junk. this space used to be the office, lobby, lunch room and bathroom of the larger area so the layout is real wanky to work with, you're better off starting from scratch. get the ceiling as high as you can or at least 10'. regular windows can really screw up your available shelf/wall space so think about using clerestory windows to let in the light. at least one very tall and wide garage style door for when you drag home a big mill or lathe. lots and lots of shelving.

the little .10FSR was the oddball of the series as it was the only one with a lapped iron piston and bushings on the crank. it also had a single needle carb with no airbleed while all the others had a low speed needle. the .28 was also a bit odd as it only came in a ringed version.

[quote]ORIGINAL: klondike17 [color=#990000][b]I ddon't want to sound like an advertising[/b][/color] but NV engines do stand out and they are unique in many ways - light weight, fuel efficient, good design, and good quality metal.

"light weight" compared to what? "fuel efficient" yeah sure... "good design" from an ease of manufacturing standpoint, maybe but otherwise not really. the anodized cylinders may be better than nickel but that's about it. if it had any real merit then everybody would be doing it instead of going through the pains of hard chroming aluminium. "good quality metal" until you list the various alloys used for the castings and bar stock parts you're just peddling aluminium like everyone else. and 1992? that was like yesterday, 90% of the engines i use are from the '70s and early '80s.

i built a killer vee over 20 years ago. started out with an OS .10 FSR and ended up with a piped K&B .21 that had previously powered a sarpolus hammer 20. very fun plane but if over powering it you should think about beefing up the wing. at the time i had lots of experience with over powering the hots design so i automatically beefed it up.

He had been using this engine for quite a while (I would say it was his favorite) and it was well worn , needing new bearings. He gave it to me and said ''I never want to see this again''. So IÂ took it home, disassembled it and found a lump of crud in the low speed jet. I put it back together with a set of BOCA bearings and tested it. WOW , what a sweetheart of an engine. Easy to tune and the power was stellar even on just 10% nitro, It had a tuned pipe also. So one day I set it up on the test bench at the field and asked my buddy to help me tune it. IÂ started it up and it purred like a kitten. He was amazed that he had not seen the goop in the carb. And being who IÂ am IÂ unbolted the engine and handed it back to him, hell it would have been like keeping one of his kids. <img src=''http://www.rcuniverse.com/forum/js/fckeditor/editor/images/smiley/msn/75_75.gif'' alt='''' /> If IÂ ever get my hands on another YS45 I am keeping it!!

RE: piston sleeve abc an unbreakable marriage?
brass cylinders will develop a "bell mouth" at the top over time because of the constant heating/cooling cycles. this is not really wear and "pinching" can more or less fix it. a chromed aluminium cylinder is far superior but much harder to make. this is why the older enya AAC engines NEVER EVER wear out their cylinder/piston assemblies unless you feed them sand.
