Paul,
Thanks for the info for ordering the Versa Mounts. While I'm
placing an
order with McMaster-Carr, I thought I would also buy the teflon for
the slide
throttle. There is a lot to choose from and its pretty
confusing. Do
you have a part number for the stuff you recommend ??
Don
There are two ways of doing it. Make the slide out of solid
Teflon 3/8th of an inch thick which is the old expensive way.
3/8th comes in cheaper low tolerance material or more
expensive close tolerance material... probably milled.
The cheaper way is to make the slide out of 1/4 inch thick
aluminum and use a layer of 1/32" Teflon on either side.
Here is the procedure for doing that thanks
to Craig Smith. It is also the way our kits for the
two rotor are done.
This is the stuff I recommend.

Thanks Paul,
That link takes me to the main index area that I was finding before.
These are the materials that come up when I search for Teflon :

This is the stuff you want.

:
Made with virgin Teflon�® polytetrafluoroethylene (PTFE) resins, th
is
material surpasses most plastics when it comes to electrical
insulation
properties, low friction chemical resistance, and performance in
extreme
temperatures.
The glass filled stuff is a no no and that may have happened
with Mark Steitle and why he noticed higher throttle cable forces.
We actually tried that and I was rather disappointed in the
friction performance.
Paul Lamar
OK , great information. You should add that to the website under the
slide throttle kit like you did for the rubber mounts.
Don Mitchell
I'll get right on it Don :)
Paul Lamar
God.....Just a suggestion.
Don Mitchell
Ask and he shall provide. Its done! Check!

Paul,
I placed an order today for a piece of 12 x 24 x 1/32" Virgin Electrical
Grade PTFE. I'll sandwich a piece between the frame and the side plate
on the downflow side. Hopefully, that will reduce the force necessary
to open/close the slide to a more acceptable level.

I think that will work. Are you using a simple push rod for your
throttle cable. Th pictures make it look like that.
BTW I have added an article on the web site on "How to build and
assemble a slide throttle".
http://www.rotaryeng.net/slide-throttle.html
It was up there a few years ago but I took it down to change
it and then forgot about it.
Paul Lamar
Paul,
I'm using an actual throttle cable assembly. You just can't see it in
the picture.
Question... how should I go about securing the cable end in the slide?
Lock-Tite?
Mark S.
Austin
If you are using the old steel button design there is room in there
for a 10-32 lock/jam nut. You need to file it square.
