Is that the plastic Kavan leak (oops, I meant tank) extender or the better metal one?

Yep,leaky as all get-out until I learned the
"thread trick", many years ago.
Probably poured several ounces of fuel
through various engines before that.
Real tank screws(not the soft junk that came in the kit)
didn't hurt either.
This Bee does not leak!
Don't ask, I never timed it.

Oh, forgot to add....
I now use a length of 1/2" plumber's teflon tape,
that I slit lengthwise(3/16wide) and twist. Compresses nicely.
For the "venturi" gaskets, I use one stock, and the other cut from fuel tube.
No leaks! [8D]

I don't understand where/how you use the thin strips of teflon tape. Can you elaborate further?

Silvaire,
After you've slit a length of tape, twist it an inch or two at a time until
the whole length looks like a piece of white thread. No flat spots.
There is a groove on the back of the Cox tank bowl where it meets the backplate.
There's also a groove on the tank extender where it will be meeting the backplate.
These 'grooves' are where you'll be putting the twisted teflon tape. Moisten your fingers
with a little spit or light oil to help with handling. There's a ridge on the backplate and on
one side of the extender which will squash the teflon in the grooves.
There is a little trial and error involved, as the teflon tape varries in thickness from brand to brand.
Thinner is better, I have found. If you find too much resistance on assembly, try slitting narrower strips.
Also avoid overlapping the teflon.
Hope this helps. Give it a try.
Bob

Perfect! Sounds like a good idea to add to the Reed valve "Sticky" thread.

Tnx Silvaire.
The thread trick has been around forever, but the teflon
application came to me a few years ago while trying
to seal a real beat up tank bowl and backplate.

What did you use for the bushing? Oillite or 660 bronze.

controlliner,
This is not my work to be sure.
It's a KustomKraftmanship item I bought
directly from Joe Klaus by phone 30 years ago.
It's a black widdow case with an oilite bushing.
The stock crank was heat treated and lapped to
the case by KK. I should build a shrine for it.
Wish parts like this were still available today.

t587y28,
Nice scan. I never thought to use a scanner to photograph an engine.
Great contrast. Using a digital camera can be somewhat of a challenge(pita),
as far as focus and lighting up close, at least for me.
I'm curious about the black band around the crankcase nose and
worried about the washers behind the prop.

TNX.

Yeah, I know it isn't a Bee.
It is mixed though.[sm=red_smile.gif]
Also.....muffler and sub port induction?
Swimsuit competition photo for sure.

dckrsn,

Is that still an.051 and if so were you able to buy the SPI piston?  If so where did you find it?  It is a very sexy looking engine.  I hope it runs as well as it looks good.

Thank you,

Bob

Hi Bob
Thanks.
I bought this TeeDee .051 new in the box, when I lived
in L.A. from '78 to '84.
It does have sub port induction and
twin bypasses with 2 boost ports on each side.
Aside from the Kustomkraftmanship
fuel body, Tatone muffler and socket head prop screw, it's exactly
as I bought it. Came with a high compression
glow head and 5 gaskets (they're still in there).
Hope the photo helps.
It runs well on the test stand, but has never been flown.

Bob

Default RE: COX 049 Bee mixed parts.

I'm finally getting around to posting my Mixed Parts 049's

The Black Widow is the most "Frankensteinized" (I have 2 identical copies of this one):

- Sub Piston Induction Dual Boost Cylinder / Milled Piston from Reggie @ Vintage Engines (About to be replaced with another combo as it's worn-out from 300+ flights)
- (Fairly) New Crankcase with polished crank and brass prop drive from Bernie @ Xenalook
- Gilbreath head / Nelson Plug from Kitting it Together
- Gibeault Mouse racing mods on Needle / sealed original Black Widow tank / back plate (Unknown vintage eBay special)
- Crank / cylinder rotated 90 degrees to keep a low center of gravity (Real reason is to make it look meaner on the Combat Wing)

The Medallion is pretty much stock except for:

- Sub Piston Induction Dual Boost Cylinder / Milled Piston from Bernie @ Xenalook
- Gilbreath head / Nelson Plug from Kitting it Together
- Sealed needle
- Neat looking original Cox NOS Engine mount / fuel tank combo (Unfortunately it's useless for inverted flight)

Nice photos François.
Here's some mixed up parts.
The 8cc stunt tank pictured is somewhat of a mystery to me.
It uses no spring or plastic retainer of any type
to hold the reed. The reed edges tuck into a groove
where you would expect the spring to seat.
The reed section of the tank is the same O.D. as the spring type.[sm=spinnyeyes.gif]
Has anyone else seen one of these?
I'll try to shoot a couple of pix with a reed installed tomorrow
if anyone wants.

Here's photos of the tank with reed installed.
Not as easy to do as with the e-type spring.
The groove that the reed sits in is just wide
enough to let it float.
In the other 2 photos I'm trying to show how
a plastic retainer wouldn't fit. Wouldn't work
anyway as the reed has to be tucked into the groove.
Still a mystery to me where it came from.
