Couldn't help myself.

Post  Oldenginerod on Tue Aug 22, 2017 9:35 pm

Well here I was hoping I'd score an orphaned McCoy #1 .049 on ebay.  

Opening bid was $1 and that's what I got it for.  Yay...  After sharing a few niceties with the seller he tells me he has heaps of old stuff he's clearing out from his dad's collection.  "I'll send you some pictures and let you pick a couple of engines or parts and I'll include them in the same package, no charge."  Well, that's pretty nice.  I get some pictures and start choosing.  Picked my two best choices and happened to mention my liking for Enyas.  Well, here's what's on the way for $1 plus $22.75 postage.  I think I scored well.


I told no lies.  "Gee, those two in the middle are pretty neat, and I like the one with the red top". Hats Off

Wow!!! I am not sure about the Enyas but the 051 & 09 Tee Dees both are of first generation thin wall cylinder design.
Good catch!

US seller.  I wondered if there was going to be a catch (can't be sure there isn't until they get here) because I can't understand why the guy was selling some stuff on ebay but none of this was listed except the original McCoy I bought.  Just seems really happy to give it away.   He seemed more interested in listing a heap of props for sale rather than the engines.

This is him.

https://www.ebay.com/sch/hm13056/m.html?_nkw=&_armrs=1&_ipg=&_from=

He also had this.
I wondered what it was and now think it could be an incomplete O&R Midjet.  Too much of it missing to interest me & I didn't want to be too greedy.

Yep. Just did a search and it is an O&R for sure.

Rod, that red top sandcast Enya .19 caught my eye as well as your's I'm sure. Add in the others and you hit the honey hole for sure.

Good on ya! - Bob

PS - despite the temptation I'm not going to his link. Got to finish this miserable MG Midget first.

Good haul for a buck, no matter the international postal cost .... if I read you right you got 6 engines for $24 +/-

and they all look to be interesting engines to play with

Yep, that's about it. The Tee Dees were an obvious pick & hopefully can get some use. The sand cast Enya is a classic and couldn't be passed up if offered. The other Enyas he just threw in. As I said, the conscience is starting to kick in due to the potential value of the haul, but I'm sure I'll get over it Laughing
Supposed to be in the post, but I won't count them chickens until the package gets here.

That's really great Rod! You know that oftentimes the seller may be "unattached" to the items.. but wants them to go to someone who will appreciate them.. especially if they belonged to family. In this case; his dad. The fact that you "inquired" (shared niceties..) likely struck a nerve.. and I'm sure that the man knows that his dad's engines will be going to a good home. Don't feel guilty Rod. You are "rescuing" those engines.. Smile

Well they got here.  I'm not even going to talk about the one engine I paid for ($1).  I just want Bob to check these out & be envious Laughing



Looks barely used.  Feels great.  Cool exhaust stack but makes the engine unusable due to muffler requirements.

Then this.  A little tarnished but tight as a drum.  Just needs an NVA.



So then comes this old thing!




Sadly quite a few dings on the head fins, but otherwise really tidy & complete.








Oh, by the way, there were a couple of Coxs in the box, if anyone's interested.


Rod.  (Like a kid at Christmas Laughing )

Well, maybe I didn't state my intentions for the two Tee Dees clearly.  Sorry, no they're not for sale.  "If anyone's interested" was just a sarcastic comment made due to me flooding a Cox forum with Enyas.  No more offers please.  They were my initial first choice when offered a "pick of the bunch".  The Enyas were just a bonus the guy threw in, but I tried to make Bob envious with the sand-cast .19 Laughing

Might have to find a muffler for the .09 Tee Dee so I can actually bolt it to something & fly it.  I'll certainly be looking at all the issues which have caused a few stumbles in Roddie's efforts with his .09.

Rod.

Envious Rod, ENVIOUS? Your darn right I am, been so ever since you posted this thread. Smile

The 4002 .19 is a thing of beauty (to an Enya guy). I always check out the nickle screws, they look untouched. Buff off the prop nut and it's perfect. Enya made two versions of this, one with an oval (like yours) exhaust port and one with an "airfoil"or "tear drop" style port. I don't know which came first or if they were produced concurrently. I have several of each so they were not just casual miss-casts.

The .09 has been disassembled and is missing the NVA. A new set of screws and a NVA from Bob Brooks fixes that.

The three case bolt .19 is the star. Highly desired by collectors and not many around. I had to go to France (ebay) to get mine. I'll double your profit. Two bucks USD for the bunch. Smile Enjoy your good fortune as I know you will. Deals like that are one in a life time.

Funny, before logging on this morning I looked at my display case and got sort of a twinge. The MG is coming to fruition along with cold weather, I will be looking for something to occupy my time. Sitting still for me isn't an option.

Actually, the screws aren't nearly as bad as they appear in the picture.  As for parts, I haven't tested them for stock yet, but buying direct from Enya is far cheaper than from Bob Brooks, particularly since if I have to ship them all the way out here, Japan is closer & shipping cost is less than from the USA

Well the 19 sand-cast went in the test stand today. Didn't bother to clean it up any. It was stuck but a quick squirt of WD and she freed right up. Gave it a good flush with fuel and replaced the dead plug with my oldest Enya plug (the first I ever got & has run in numerous engines), a couple of flicks & she was running on the prime. Sounds fantastic. Compression is perfect.
So, thought I'd give the 4002 19 a shot as well. This one hasn't been dismantled either, but got a good anti-freeze cookin'.
Same deal. A couple of flicks and off she went. Pity these ones aren't for flying Laughing

Update!

I gotta admit, I feel a little sorry for the old McCoy #1.  It was my original purchase in all this, but apart from an anti-freeze bath it has been sadly neglected as I soak in the wonderment of the other engines that were included with it.

I've spoken about the two Enya .19s.  The Enya .09 has cleaned up nicely and just needs a spray bar before a test run.  I didn't boil the two Tee Dees as I haven't dismantled them to remove the plastic and anodized parts.  They were both locked pretty solid.  Well, today I gave them a good spray with brake cleaner, followed by a generous soaking in WD spray.  Attached a prop to each and wriggled until I gradually got some movement.  The .09 has come up nice and free.  I'm glad because I don't have the .09 wrenches to tear it down.  The .051 is a little more stubborn. While it does turn, it's very stiff, so I'll dismantle it and see if I can get it devarnished.  Both of them showed lots of really thick castor varnish.  For some reason the brake cleaner worked a treat on the .09, so the .051 must have been put away with different fuel residue inside.  I'm guessing the crank is really gummed.  We'll see.

Oh, and the McCoy?  Well, I'll get around to it. lol!

Hey Rod, Regarding that little Testors/McCoy .049 engine..  Huh...  How does it compare to the reed-valve/"pipe-bomb" engines in terms of inter-changeability? I recently posted about my rotary-valve engine sourced recently; that has a broken crank and connecting-rod. I don't know much about the Testors/McCoy .049's.. and was wondering about the cylinder/piston inter-changeability.. between the reed/rotary-valve engines.. as well as the crankshaft inter-changeability between the different "rotary-valve" engines.

My rotary-valve engine looks a lot different than yours..



I'd really like to source a new "crank" for it.. if I knew that I could interchange a cylinder/piston set that would work. The cylinder on "my" engine, looks quite similar to the reed-valve variants of which I have a couple of.

Have you ever removed the "crank" from one of these engines; having that type of starter-spring housing? Is it similar to a "Cox" drive-plate in terms of being "splined"? I would guess that it is.. but as I mentioned.. I'm not familiar with these engines at all.

Hope that you give a report on that little engine.. that led you to such a "great-find" in the vintage Enya's and Cox Tee Dees!

Thanks!!!!!!!!!

Roddie. Even though the cylinder design differs between your "Red Head" and mine I'm pretty sure most parts are interchangeable. I also think you'll find the Pipe Bomb cylinder/piston will fit. Of course, the crank won't as it's not drilled for the front rotary valve. As I mentioned in another post, I have spares if you get desperate.

The splined drive plate removal is simple. Whatever you do, don't try to lever it off as the one-way clutch is easily damaged. Just lay the engine on it's back and give the end of the crank a light tap. Once the drive plate is off just be careful the starter spring doesn't try to escape. Laughing

Thanks much Rod. Thanks also for offering a replacement crankshaft.. but I'll try to source one locally. This engine wasn't high on my list of modelling priorities.. but I got curious last night and took it out of the "box-o-engines" after reading about "yours". It had a Testors prop mounted.. and the engine was mounted to a white-plastic firewall when I received it. I turned the prop and thought.. "NICE.. it's not stuck". Then I noticed that the piston wasn't moving.. Shocked

I try to archive photos that interest me, of what I've seen posted here on CEF.. and have an engine folder of various manufacturers. In my "Testors" folder were photos that Kim Stricker posted back in 2015 of a very similar engine.. mounted to the same (Cosmic Wind??) white-plastic backplate.. complete with the same nut and bolt nose-weight.. as was on mine.

Kim's photos..




my engine..



I found that to be a very interesting coincidence. What are the chances that I'd receive the same engine mounted to the same firewall as one that Kim posted.. and I'd saved in my folder? I'd previously thought that nose-weight to be a "red-neck" mod. but apparently Testors used them to balance the airplane.

My Cox Cosmic-Wind (previously a Testors mold) has a significant lead-weight in the nose.. held into the bottom/front section with a small sheet-metal screw.





Apparently Testors produced "two" different-size versions of their Cosmic Wind model ("Silver Wind"); both being 1/2A size C/L models. The "larger" having the front rotary-valve engine.. and the smaller likely having the less powerful reed-valve product/"pipe-bomb" engine.



I believe that Cox later acquired and modified the molds from Testors to reproduce the smaller 16" span variant for their newly designed modular product reed-valve .049 engine with the horseshoe-backplate.

I have the 1986 version of that Cox model.. shown here with an ExModel Engines "Black Lynx" h/p engine installed.



There's still a very slight wing-warp on the inboard T/E. There were warps on "both sides" that I tried to reset by clamping a while back.. but I'll need to re-apply a clamp and use my heat-gun in an effort to permanently set it. I have reservations with flying the model.. but I'd like to straighten-out the wings regardless.

The Testors/Cox story of the Cosmic Wind model is one that I'd like to learn more about.
