Engine Build Article???

LAST EDITED ON Jan-28-04 AT 01:59 PM (CDT)
 
A couple guys have hinted that an article on an engine build be submitted to SN. What's the feeling here, should I do it with the stunt engine I'm beginning?

I think it would make for interesting reading. Go for it!!

A strong "Yes" vote here, Randy. For those of us not familiar with the machining process, this is great stuff!

Randy,
You've got my vote. I think it would be great to see an article in the PAMPA magazine on building a stunt engine.

Randy,

DO IT!! You are in a unique position to demonstrate these techniques to others. All will benefit.

Hey Andy,

Good to hear from you. I didn't get out to the meeting last Friday night with the weather and my wife recovering from hip replacement surgery. Did you make it out?

Randy,

I think such an article would be of great interest. If nothing else, many people who tend to view engines as mere appliances would begin to understand materials selection, run-in, fits, etc.

On the other hand, while of great interest to you and your wife, I would like it noted that I have no interest whatsoever in knowing how and why you chose to machine the ball and socket used in her recent operation.

I'll tell you anyway Dan, I'm cheap and she was game. (I did boil the lathe chuck and tools) Kevlar makes great stitches too.

I would like to cast my vote in favor of seeing such an article. Are you going to fly any of these masterpieces? If you are you should get bonus points for cojones-I doubt I could risk something that nice to the whims of gravity!

That's the idea Bill, I want to fly with my own engine. Thanks for the compliment!

Is it done yet?

Well,

I'm about to start on the stunt engine so with your support I will also prepare an article or articles and submit them to SN. Thanks for the help guys.

Randy,

Stunt News is crying and craving something so different, innovative and informative. Go for it. I can't wait.

Randy; Puleeeeze do it.

Just out of curiosity - if one wanted to make a modern AAC or ABC stunt engine, how easy would it be to find the high silicon aluminum for the piston, and how hard would it be to chrome the sleeve? Would you do all this yourself or send it off (to Bob Oge, etc.) for chroming? Would it be difficult to achieve all the proper fits using a run-of-the-mill lathe?

Its interesting that Loet Wakkerman, who makes his own F2D engines:

http://home.wxs.nl/~wakke007/

buys his pistons and liners from someone in Russia. Since basements aren't common in Holland (at least, I think that's the reason..), he's got his lathe and mill set up behind a partition in his bedroom!

Interesting.. he's got pictures of the world champion Metkemeijer FAI Pylon engine on the site now..

Iskie,

Being an experimenter and having done some hardchroming, I'd attempt to do it myself. High silicone alumunum is fairly easy for me to get ahold of since we work with it quite a bit at work. As far as the fitting goes, that would be a challenge, but not impossible to overcome. You would have to fit and ABC or ACC as you would a lapped engine then remove the additional material for the plating thickness. I'm sure it would be a frustrating iterative process.

I'll tell you anyway Dan, I'm cheap and she was game. (I did boil the lathe chuck and tools) Kevlar makes great stitches too.

Randy,

I was being silly, but for a reason. My father-in-law died about a year ago and he had his basement stuffed with a large lathe, new vertical mill, two-each bandsaws for metal and wood, drill presses, hydraulic press, grinders on pedestals--evidently one cannot have too many of these, as he had 8 of them and at the time of his death was building a couple more--and a bunch more metal-working tools.

My son and I got the assignment to clean and organize Glen's shop.

At one point Joshua came up with a superbly polished piece. Odd shape and all, we simply could not imagine why it had been fabricated, having already made the assumption Glen had made it along with all the other bits laying around.

Turned out to be the ball from my mother-in-law's first hip operation.

That freaked us, and I still don't know what ultimately happened to the piece which at first was so intriguing.

Dan,

Old people save some weird stuff. I wonder what my kids will find after I leave this life. Guess I'd better go through it all. On second though, why deprive them of the confirmation of what they suspected all along? Dad was a strange guy, wonder why mom stuck around.
