I planned on making a shift knob for my Ghia, I noticed that in the manual it says "resting your hand on the shift lever knob while driving will cause premature wear to the transmission"

so is vw busting my balls, or is there a good reason that they are made out of plastic? I planned on making it out of a nice wood, either ball shaped or T shaped with a metal nut-to thread it onto the shifter.

Is there a certain weight I should stay under or is this all B.S?

By the way, I don't rest my hand on the shifter anyways.

Personally, I don't think anything fabricated for a knob would be heavy enough to continually force the rod down and put pressure on the tranny...

I am pretty sure the reference is in terms of having your hand resting on the shifter...which truly adds some real weight: your arm weighs on average 9-11 pounds...and while that's "dead weight" most people with the habit of doing that likely forget that they are putting force on it, and perhaps even applying pressure as well.

I have a few different shift knobs, one solid wood... and it's not an issue.

Make away, in my opinion. But post pics when done!

I want to have a woodworker I know make me one as well out of some nice hardwood. He can turn it on a lathe but I don't know where to find the right size threaded insert so I can screw it to the shift rod.

I didn't think much harm would become of it. I tried resting my hand on the knob and it didn't feel like I was putting to much pressure/ weight on it, I probably just couldn't tell. So I just wasn't sure.

I shall post pics up when it's done! Going to have to find some wood I like from a guy I know Wink

And jpjohns - the thread size for a stock shifter is 12x1.5 I belive, so if he has a tap set he can take some round stock and just drill and tap it then insert it into the wood via glue/ epoxy, or press fit. Or find a nut with that size.

Lol... I don't know why I didn't think of just cutting the threads into the wood. I was looking along the lines of a threaded insert.

They have a place for you to upload your own image/graphic whatever, but I don't know how that works

Oh and jpjohns -
I didn't mean cutting the threads into the wood. I meant that since your friend has a lathe - depending on the type - could just take some "round bar stock" and turn it down however you desire. like with a taper or something, and then drill and tap that, and inset it into the wooden knob via epoxy. I think you can cut soft metals such as aluminum and brass on a wood lathe.

Tried out the T shape just to see if I liked it, I don't care for how it feels. Although it is comftorable I think I'm going to stick to a ball shape

when resting your arm on the shifter it puts force on the shift fork in the transmission witch rides in a grove in the slider hub. it then will constantly rub against one of the sides instead of float in the grove and will wear out the shift fork faster. especially 3/4 shift fork because it is made of brass.

this is a pretty cool wood knob: http://www2.cip1.com/ProductDetails.asp?ProductCode=C38-I-105B

I tried several searches on Vw knobs and never came across the cip1 website, I like that option a lot better than others that are sold. Too bad it's out of stock! I might be tempted to get one.

Cip1 shows some Rosewood ones on their site but when you click on the link they are out of stock. Discontinued I believe.

That place has some beautiful shift knobs!

i don't know about the tools part Wink but i suppose i make up for that in being creative. turning a block of wood into a sphere will take a bit of creativity since i don't have a lathe or router, but it can be done.

on the t shaped one i tried i used a piece of a chair we were throwing away
here is another i made from the chair, i like this style quite a bit. i don't know if i will use it, but i got a bit of joy smashing the chair, and it only took two cuts with a hacksaw.

For the Hurst shifter in my ghia, I bought an engraved billiard ball shift knob from a vendor here. I can't find it in the classifieds, but I believe it was this vendor:

You can see it in this picture.

I'm not really a woodworker, but was able to make one for my EMPI Hurst clone I am happy with. I purchased a hardwood ball, already turned, with a small flat spot, from a craft supplier, stained and sealed it. I drilled out an oversized hole and epoxied a 3/8-24 nut in the bottom. The Hurst shifter needs a knob with a hollow around the center hole to allow the reverse release collar to enter up into the ball when pulled.

I also drilled a another flat-bottom recess in the top to accept a Wolfsburg metal button emblem.

Ultimately I like it but may someday do a replacement turned from a decorative hardwood.

The Hurst shifters I have had work almost as well as any of the high dollar shifters. They also just look right in a vintage VW.
Nice knobs guys Shocked

This brings me to another question. What exactly does putting in an aftermarket shifter do? Shorter travel, smoother, what? I had a hurst in old car but it was a weird slap shift thing. So what does it do for a manual trans?

Most aftermarket shifters shorten the throw between gears to varying degrees.
