Subject: Low cost Slide throttle kit?

 You read my mind. I was just working on the final drawing.
 I talked to my pilot buddy down in Torrance yesterday that
 is going
 to make the parts. He builds a lot of parts for Boeing and
 Airbus.
 His tig welder is an artist as he tigs welds aluminum 8
 hours
 a day day in and day out.

 He wants to build the whole thing including tig welding
 them up.

 But that is a costly thing for me to do as the tubing
 bends
 alone are about $30 each. I am sure he would not do less
 than
 ten at a time.

 If ten people come up with half the cost I might be able
 to
 swing it. Or perhaps everybody sends me bent tubing.

 Shop around and see if you can find tubing bends cheaper
 than Burns Stainless is charging. Two inch OD .065 wall 180
 degree
 bend. http://www.burnsstainless.com/

 Here are some pictures  of his shop.

 He also just acquired a large Fadal NC mill so he will do
 the
 spacer as well.

 Why don't you take deposits, of say $50 up front, and balance due when a
  run of kits is completed and you have the full costs figured out?
  I'm going to want a set of the aluminum intake rings too. what were
  they, ten bucks each? ship 'em all together when the slides are ready.
  C. Smith

  That is another possibility. The rings were $5 as I recall.
  I am going ahead with the slide throttle kits less the tubing bends and
  Teflon anyway.

  Paul Lamar

  I think a $50 deposit up front is reasonable Paul.  What ever you guys
  decide let me know and I'll send the $$.

  Mike C.

 Paul,
 Me too.

Paul,

I am still in.  Just let me know how much.

OK I have come up with a compromise solution here.
Since there are several configuration for mounting
the slide throttle and intake runners it is not a good idea
to weld the 180 degree tubes to the outer slide cover.

What we can do without accepting a bunch of money in advance
is weld short tubes to both inner and outer covers and everybody
can do their own thing with rubber couplings, hose clamps and
180 degree bends. If you get something you like you can
then butt weld the 180 degree bends to the short tubes if you wish.

In certain airplanes, like canards, you may be able
to run straight tubes. Other airplanes you can go up and over
the engine or tilt them over along side the engine if you
have a side by side airplane. Lots of flexibility in
this approach.

What do all you slide throttle buyers thing about this idea?
