Robert,
Let me know how it works... I heard or read somewhere that an anodized finish was "slicker" giving slightly more RPM.

icerinkdad, The anodize process does increase the lubricity of the aluminum to some extent. However the all silver ones were probably anodized clear if i had to guess. This would have been done for marketing , to keep the aluminum from tarnishing while on the store shelves. I was in the electroplateing buisness for 20 years and our sister company did all the anodizeing, while we did all the plateing. I used to have my 1911 race guns anodized to add hardness to the alum frames & also keep the alum from galling while in contact with the steel slides. The wild colors looked cool too....didnt help my shooting any though......Gene

Gene,

That myth has been going around for a long time. The plain aluminum Cox crankcases are not clear(type1) anodized. After having anodized 1,000's of Cox engine parts I have never come across a clear anodized part. Nor does any of the factory Cox CAD files I have call out for clear anodizing on any. I would think your 1911 was hard coated(type 3) anodized.

LAter,
Tim

Woo Hoo! it was in my mailbox this morning! What service!

Now I need a red tank, red product backplate or one of the old Goldberg adapter mounts for I do have one of the old postage stamp backplates in red.
Anybody?

Robert,
Red delrin backplate #bay No 380118858436 , these are mixed I have purchased a few a couple of which I believe to be early Killer Bee 051 backplates with larger venturie , no screen and fine thread needle valves.

Stewart, thanks mate, I was pretty sure I had seen those somwhere.
The picture for that item number shows one with the screen and might not be for the KB .051 but that would be fine. Easy enough to mod it if not. If I get one without the screen as you have, it might very well be so.

Now if I were to find a blue back plate I could call it my RGB (red, green, blue) .049! heh.

For next Christmas, hows about a red case? Then I would need a Green drive plate and backplate!


Robert

SGC

Robert,
I meant to say KB 049 (red)and 051(black) backplates, he had both when I purchased mine. Out of the lot I bought I only receive 1 KB051 and 3 KB 049 backplates out of 6 of each red and black, the others must just be product engine backplates.
Also 2 of the KB backplates had the wrong (not fine thread )needle valves fitted , but these can be purchased from "Texas Timers"
All 3 engines pictured have DD heavey duty killer cranks fitted, the top left engine has an early TD piston/cylinder, top right has a modified SS piston/cylinder (exhaust port recut, selected piston for good cylinder fit that is also lightened) Doug Galbreth head/nelson plug, 3rd (black) has an early Black Widow piston/cylinder No0 that aperes to have a tapered cylinder , I lightened the piston , head is an australian made "Billet race cam" for std 1/4-32 plug with Merlin glowbee style plug fitted.

Stewart, those engines are precious.

So what do y'all think about having a candy cane striped spinner on this?

Robert

Tim, thanks for clearing that up on the anodizeing. I was just guessing it added lubricity, all be it a bad one. Thanks....Gene

Anodizing increases the surface hardness of the aluminum by a considerable amount.

unattainium

Just be careful anodizing stressed parts because it weakens them by having the very hard coating initiate cracks which then propagate through the rest of the structure. It is a bad idea to anodize con rods, for example.

BMatthews

I vote for a "Rudolph" engine. A red spinner and back plate, bronze colored crankcase and tank bell with green anod'ed display only glow head and either a black plastic backplate or one of the old gold painted pot metal ones.

And if the front corners of the case could be "splash" or two color anodized with silver and black eyes that would complete the image.

Do I win anything besides the "ugliest engine idea" award?

build light

Bruce, I bet someone else could come up with one uglier. Maybe me!

I think I want a few more later.

An all green one for St. Patrick's day 'cuz everyone is Irish on St. Paddy's day!

Green Drive plate, Purple case, gold tank and red backplate for Mardi Gras!

I'm thinking Pink with red hearts for Valentines day... I think i'll let someone else do that one.

Ah the Bronze color with black drive plate and tank back call it old number "7"

I really like the idea of a cool, metallic ice blue with the natural aluminum drive plate

Stewart, I ordered two of the red back plates like yours, thanks again for the item number, and both have no screen and look like the intake hole is larger.

After getting it all together it looks nice! I need a better camera than the one I have...[&o]

Robert

Robert,
Are they fitted with the correct needle valves ? They should have fine thread needles, check to make sure they screw in properly , if you need to get the fine thread needles they can be got from Hank Nystrom @ Texas Timers.

"Even iffy pictures would be better than just teasing us with no pictures."

Your right and I really tried and came away with a little better than I had hoped for so here you go!

A more accurate rundown of the assembly:
TD .051piston and cylinder set
TD glow plug
Red Cox rubber spinner
and finally a red OK Cub prop! I just had to do that to cap it off good and proper.

Thanks for sharing, pretty neat engine. the red prop is a nice touch!

Here is one that is some better but I still see much room for improvement.

What kind of cameras are some of you using to get those spectacular close ups?
