I just want to see if there is any interest in this shift ****. I drew it up in Solidworks today... I don't know how much it would cost to machine, but assuming that it will be available at a reasonable price, who would be interested in it? If you have any questions or suggestions let me know. Thanks.

If you don't zoom in the pictures are a little messed up...

Looks uncomfortable.

 

I was going to say. Looks cool but the ergonomics look a bit off. maybe smooth the sharp top edges into a rounded edge, maybe start about where the groove is cut, and slowely curve inward until it flattens out on the top. then inlay a smaller rotor into the top... so itll still have the rotor shape and rotor on top, but itll be more rounded and easier on the palms. just an idea

also the rx-7 looks a bit odd. maybe eplace it with an actual rotor. just a simple gear in the center and the corner seal holes on each corner, then maybe a small rx7 in the center of the rotor? not tryin to change you whole thing, just giving some criticism

Poor chop but you get the idea

 

I had one made from a rapid prototyping machine awhile back (I lost the drawing, so I redrew it today) but it was surprisingly comfortable. Your second knuck goes at the front point and when you wrap your hand around the **** it fits well. Just my opinion, but keep the suggestions coming.

Looks seriously uncomfortable...

I'd be interested in a Voodoo-style sphere **** so long as it weights close to 300 grams (stock **** is 350 grams) and isn't *too* large... and for less than 40 bucks, shipped (...yes, that's asking a lot).

Also, having some sort of insulation between the threads and the **** would be a good idea, since that way you might be able to avoid a superheated/superchilled ****...

 

HOw about just a revision of the RX8 shift ****.

 

You could keep the original shape but surround it with some plastic/rubber/whatever. Preferably in a spherical shape.

 

+1, and maybe make the top look like the actual rotor, not just say 'rx-7'

 

if it was rounded and the top be a rotor with the RX7 on it I would be in for one!

 

Alright, I'm going to tweak it this afternoon, I'm going to increase the radius of the bottom circle, so the overall shape will be more cylindrical, round the top more, and make it more rotor looking. Thanks for the input.

you know what would the estimated price be!

I don't have a good idea of price yet.... Right now I just want to get a design and see if there is interest. Once the design is final I'll take it to a machine shop and see how much it will be to get it milled.

-Andrew

 

it be cool to have a couple designs like rx7, fc3s, fd3s, or like the one dude said "make it look like a rotor"-with like the designs and seals cut into it, even making the top look like the infini symbol.. Either way thats pretty cool that you making things on your own mang!!

 

Solidworks FTW.

 

id buy if i could get it annoed black.

 

This one has rounder edges, making the whole **** rounder, I was going to make the base larger, but the **** was to large that way. Let me know what you think about this one.

-Andrew

 

I like it. How long did it take you to design that?

 

It took a few hours. Those of you that have posted criticism what do you think of this design? And what else do you think should be changed? Thanks.

-Andrew

 

that definately looks a lot more comfy.

 

I'd buy that in a heartbeat

 

Yeah that looks awesome

 

Looks close to the drawings I made. Closest is on page 4. https://www.rx7club.com/2nd-generation-specific-1986-1992-17/gauge-interest-shift-knob-509125/

I didn't get the interest I was hoping for so the project got put on the back burner.

 

I remember seeing your thread Wizz, thats what gave me the idea of seeing if people were interested in this design. I have a cylinder shaped shift **** and really like the feel so I thought I'd make one similar, but with a rotary look to it. I want to see if people are interested to see if I should make more than one. Either way once my seven is back on the road I'll have one of these for myself.
-Andrew

 

When I do get back around to my project, I will more than likely make the round version. Cost being the main factor. And I have a **** shaped similar and I like the feel. Maybe we could trade ***** after I get some made?
