I have the parts in various stages of build.
The slides themselves are the easiest part...just a flat bar with the correct holes and spacing.
The housings are partially done....I am experimenting with bearings for the "floatation" of the throttle bar.
I have 6 bearings holding the bar up (from the bottom of the housing) and 4 bearings to center the bar int the chamber.
I have indented a piece of rack (straight gear) into the side of the slide bar.
This will be pushed by a 90deg piece of gear I have to cut down.
I figured the gear had to have the circumference equal to the total movement of the slide (through 90 degrees).
To make the gear smaller, I have cut down a full circle into just a 90 deg piece (approx) keeping the hub intact.
The slide works so far, and has about a .0002" clearance at the bottom and sides.
So far I have been working with aluminum but am considering making the slide out of Delrin to make it more slippery.
I am not sure how the Delrin will hold up to the heat of the manifold.
That's the progress so far.
As to making a bunch of these....had not thought of it seriously.
