I made a shift knob woo hoo!! updated post
�
�
I really did make it........................on a Haas CNC lathe. I have been waiting quite a little while to make this fine piece, at least thats how I look at it. I had the CAD drawing for it for several months and the CNC program, that I wrote by hand, for several weeks and today I finally managed to get my hands on the lathe to run it. I really wasn't sure just exactly how it was going to turn out, sometimes a picture or drawing doesn't always tell the whole story. I nearly killed it when the lathe chuck applied too much pressure to the part the shifter boot grabs on to, so the chuck mashed it into a triangular shape rather than round. However I managed to salvadge it but I was a bit pissed. The knob is made from 6061 aluminum and is a perfect fit to the car. The picture really doesn't do it much justice because of the glare from all the lighting and it also keeps you from seeing the top of the knob where it is undercut by approximately .050" with WRX engraved on it. I hope you guys like it, I sure do. So who wants one?

Kind of looks like a chromed out titanium STi shiftknob, nice piece of handmade shift knob though ;)

Looks nice, and I would also think it would cool down faster in the summer than the Ti one:D

i also have hand made a shift knob. it was made using the cold water push thing from a mcdonalds bathroom (cleaned of course) and using a special lightweight plastic shaft that my mother machined to a Legacy shifter's spec at Moog.
when full screwed on the "cold" and "chicago faucets" labels faced the driver so you could read them too. i loved it but havent moved it the the scooby.

not to get off topic, but i was wondering if 99RS shift boots had elastic in the top band or if i would have to do the mod using rubber tubing to tighten it at the base of the shift knob's shaft. im guessing its the latter but would be pleased to hear otherwise...

schmecky: I can't get a good shot of the top thanks to my crappy digi cam but if you look at the top of the sti knob it looks somewhat similar.
LinuxGuy: I did get the idea from the sti ti knob but look at the two and you see mine is very different. I didn't want to copy it but I did make one just like it but it is bigger in diameter and I don't like it as much.
WRXcellerate: pm'd you.
NimrodBoz: Thats pretty cool. I had a 2000 RS before my WRX and they both appear to have the same shifter knob and boot setup. If you haven't actually investigated the setup the boot just slips over the base of the knob where a ring in the boot locks into the groove there at the base. I designed my shifter knob to accomodate this stock feature. This of course is assuming your RS is the same as the model years that follow it.
Here is a shot of the STI ti knob for all to compare mine too.

That looks really clean... the picture isn't showing but I can see the resemblance with the STI shiftknob.
| creature546 | 04-15-2003 09:37 PM |
lol i did the same thing as you last year in my metal shop class. mine was a round one knida like momo (i think) it was a lot of fun making it though.

What type of Haas lathe did you use. The shop I work for just bought a HL-4

Very cool! :D Only thing differently I would have done was radius off the bottom 3 edges.

if the sun is out, and you leave the scoob outside ...
is the gear knob hot?

| randolph-rs | 04-16-2003 09:03 AM |
The lathe was a HL-2 so its a little older but still runs well. As far as heat from the sun I could only assume that being exposed to direct sun light would cause it to be quite hot. Aluminum is a very good heat conducting metal and can hold heat for some period of time. I just plan on avoiding direct sun light. Since I am in college and nearing graduation I can say that I only have time to make about 5-10 of these knobs if anyone is interested in one. If you are please pm me for details. I am definately not into making them for a great profit just for the cost of materials the rest is just getting the experience on the machine.
| randolph-rs | 04-16-2003 08:12 PM |
I am planning to rework the engraving tomorrow so hopefully I can get that done and post some pictures for everyone to see.
Thanks guys for the nice comments it makes it all that much better.

Very cool idea. I might have to try my hand at this.

Excellent piece of original work!

very nice work

very nice. splendid piece. I still prefer the leather but that is awesome.
| randolph-rs | 04-21-2003 08:41 PM |
I have finally managed to get a somewhat decent picture of the top of the shiftknob. It really isn't that great but it was the best I could get out of my crappy digicam. The engraving is about as close as I could get to the real deal and I actually had to use CAD/CAM software to draw up the "R". I think it looks pretty good but there are still some things about it I am just not happy with, thats the bad thing about being meticulous. It's all about trial and error.
| randolph-rs | 04-26-2003 08:52 PM |
Here is a shot of the 3 shift knob designs I have worked with thus far. The one on the left was a special request design while the one in the middle is the same as the picture above, and the one on the right is somewhat of a STI ti knob knockoff. All of these knobs have a brushed aluminum finish which I think looks nicer than the polished knob above. The brushed finish is a little bit more work to turn out than the polished is though. The STI look alike is one of a kind and I have no plans of making any more of them it was basically a see if I could do job. It is also a bit bigger than the STI too. I hope to add one more design to my collection to make it complete, until then I hope you guys enjoy.

Very nice work. Have you thought about a non cylender based design? I triesd to work one of these but its a bit tuffer to draw up.
| randolph-rs | 04-26-2003 09:53 PM |
I have thought about it but there is really nothing I can do. I do not have access to any better CNC machines. It would take a lathe or even a mill having more than 2 axes to produce a knob of a non cylindrical design. Our VFO mill has 3 axes but the lathe is only a two axes machine. Of course I could draw it up all day long on my CAD software but I use 2D graphics mostly right now. I will be learning 3D this summer so I guess I will see where it takes me.
| 128d | 04-27-2003 12:11 AM |
Its amazing what you can do with CAD in 3D but it gets a little tricky. Good luck.
| sick1.8t | 04-27-2003 12:30 AM |
what software do you guys use? I do most of my 3D cad in Autocad 2002, but its kind of a pain. the only reason i stick with it is because i know how to use the program so well. i've started in on unigraphics and solid edge, but it will take a while to learn the whole program. if you want to make a shifter that is ergonomically shaped, solid edge or unigraphics is a better choice in my opinion.
| 128d | 04-27-2003 12:42 AM |
I do almost all of you work in Auto CAD 2002. It is an awsome program but takes some time to learn like you said.
| MixeD_MenacE | 04-27-2003 02:01 AM |
pro engineer is pretty nifty as well...had some old shifter designs that i had monkeyd up before. Hopefully i'll play around the Haas CNC mill and lathe some more this summer. Nice job on the knob design!
| mpiscool | 04-27-2003 02:24 AM |
pro engineer is annoying as hell, I have just spent the last semester learning it. While it can do some pretty sweet stuff, a program like Solidworks is way easier to use.

SolidWorks is a nice program but, I still think CAD is faster wonce you learn all the comands.
| HokieEngr | 04-27-2003 01:27 PM |
Pro E is pretty good I think I used it back when I worked for Nortel. Unigraphics (UG) is a PIA though. That's what GM uses.
Nice knobs btw :cool:

Got my Shiftknob

I purchased the shift knob on the left and it is awesome. I asked Jami if he could make a knob for me with my specs and he was off creating the best looking knob in my opinion that I have ever owned. When he starts making them again, jump on it. It is I CANDY. Thanks again Jami for such an awesome knob. Take care, Lee

Man, great stuff, nicely done knobs. Make me wanna do CAD :)
What is the cost?

What are you saying there LJ. Need to be a little more specific.
