917 shift knob - Page 4

Randy Webb · 08-23-2004, 02:05 PM

I think the best thing to do is to glue the Momo knob adapters into the custom knob. No danger of splitting and the Momo way of putting a shift knob on is common on Porsches (and other cars). It's the way I put various knobs on my cars.

Can you buy just the adapters, or do they only come with there knobs?

Walnut and maple would be a good match.
Hard and not very light.

76911S I would be interested in one of your shift knobs too, and if it'll fit your car it should fit mine, also a 76 911S.

Mrdi,

What are your thoughts on maple and mahogany?

Randy Webb · 08-23-2004, 04:16 PM

Momo sells the dapters by themselves. But the question iw what retailer carries them.... Hey maybe there is some retailer with a 911 web site that might be interested....

Not to throw a damper on things 76911S, but are you sure you can bring them in at $30 or less? That's quite a bit of work even if semi mass produced. Particularly so when you factor in the insert for attachment to the shift lever.

Well, that’s a good question. If its laminating and turning, then I do not see a problem. If I have to engineer a way to mount the knobs, then it might be more..

I’m not suggesting it so that I can make a big profit. If I can get a knob for myself out of the deal that’s all I want..

It’s a Porsche thing.. You know..

Mahogany is a good choice, will turn and has a close grain.medium hard if you choose a good mahogany, NOT Honduran!! Too soft.

The maple is a little hard to turn easily with the mahogany.
Because of the change in hardness and density when you move from one to the other when turning the knife will want to "bite" the softer of the two.
Ash is a little softer than maple and white.
Hickory is also white with just a little yellow and about the same hardness as mahogany.
Both are available and not too expensive.
Padauk also would be a good choice for the dark
Mahogany splinters, and varies so much with density, but if you can find a nice piece of aged mahogany, that will do!!
Do you have a lathe?
do you have experience turning?

Just refreshing my memory
Please dont take offense
I'm too old to do homework

76911S · 08-23-2004, 07:39 PM

None taken..

I will keep all informed of my progress..

Thanks..
Mark..

Mark,

Very cool project....
I would be interested in one for a 901 crush sleeve type mounting.
I will be eager to hear about your progress.

Thank you,

GeorgeK · 08-24-2004, 05:56 AM

If you factor the costs in, then you'd be better off just drilling it at the correct diameter (someone has a 915 knob they can measure the hole from?), then let the buyer adapt it to the lever.
I really don't see the point of the crush sleeve. I have an exact replica of the std 915 knob, turned in auminium and black anodised, and it is pressd on the lever built up with tape, and it holds *very* hard, no turning or moving. If I want to remove it, I know it will come off, by pulling much harder than I do when I shift, yet without bursting a hernia.

KobaltBlau · 08-24-2004, 09:03 AM

What kind of tape do you use, GeorgeK? I do agree about drilling and letting the buyer adapt.

76911S · 08-24-2004, 09:17 AM

I do not know off hand, are 901 and 915 shift levers the same diameter?

Mrdi · Mrdi's Garage

It is very difficult to drill a perpendicular hole (Plumb) in a round object.
The hole should be established before turning, but could be of minimal size.
A pilot hole could be enlarged to the correct diameter.

TerryBPP · 08-24-2004, 09:32 AM

Mrdi, I would have never thought to drill a pilot hole first. The intellect of this board always amazes me.

GeorgeK · 08-24-2004, 09:43 AM

Andy,
I used plain body shop masking tape. A few turns, try, a few more turns, try again, until I had a hard to remove, but not hopelessly stuck shift knob. Has held fine for 5 years now.

76911S · 08-24-2004, 09:50 AM

That’s how I do the bottle stoppers, I have to drill a hole so I can mount them on a special chuck, then I turn them round.. I will use the same chuck for these. I will be able to enlarge the hole to what ever when I’m done turning..

I sell bottle stoppers for $20 by the way. If anyone is interested. The picture on page two is just a sample I have lots more and can send pictures. Holidays coming and all..

Thanks..

P.S. Sorry for the self plug.
