Some time ago there was some discussion on producing slide throttle
parts or complete units, I don't remember which, maybe both. Is that
going forward?

If not, there is a machine shop owner who is also a member of our EAA
chapter who might be persuaded to make the parts. He has a NC mill and
lathe. Looking at the parts, could they be more economically produced by
a NC punch press? Would punch press made parts be acceptable? I asked
him about transferring the design info to his NC machines. He said he
could use a dfx file. IGES would also be acceptable, but he prefers dfx.
Since Rhino could produce both, it looks like a match to me.

I don't want to step on anybodies toes, and at the same time I don't
want this effort to just languish. I have hopes that the slide throttle
would be more acceptable to builders if they could buy parts, or the
whole assembly. So, I might be willing to up-front the materials cost
and initial production run if it doesn't prove too expensive. Provided
nobody else wants to do it.

Feel free Doc. Do us all a favor and put it into production.
Yes our first ones were NC punch press. Front and back plates
were 3/16th 6061T6 about the limits of the punch press.
Very cheap to make. On the order of $15 each.

Here are some pictures.

3/16th thick square flanges could also be punch pressed.

The 3/8th inch thick  Teflon slide needs to be milled, laser cut
or water jet. Whatever works best with Teflon.

The 3/8th thick aluminum spacer between the plates also needs
to be milled or water jet cut. Too thick for the punch.

I will talk to him. It would be helpful to have the Rhino drawings for
him to look at and to produce a fixed file from.

I can make prints of the version 12 pix you sent to start things off
with, but I know he is going to want the dfx file.

No problem Doc. I can give him Solid Works files which
usually work better when doing NC stuff. Or Iges or dxf
his choice.

We now have two styles. Long travel 3 inches or short
travel two inches. The long travel is an inch longer.
