Shift Knob Replacement

I've been thinking about making a wooden shift knob for awhile. I also don't like the hole on the back of the factory shift knob, so here's my idea on how to solve that and still have a set screw to hold the knob in position.

Use a spring that's reasonably stiff, and compress it with a cap screw that's designed to bottom out when screwed into the knob. I was thinking you could just use a standard flat head allen bolt screw, screw it into the knob and lathe it down to match the outside surface of the knob. Since the screw will only go in so far, it will always be flush with the surface when you screw it in. The compressed spring will do the job of seating into the lock slot on the shift lever. You only need to thread the hole as far as the cap screw needs. You'd want a fairly coarse thread for the cap screw if it's going into wood.

The custom knob I had made has no set screw. Solved the issue by having it fit the stock threading with Locktite. The top plate with the shift pattern fits into the knob with a minor amount of pressure, but easy to pop out for setting it straight... once the knob was screwed tight, the top plate had a little epoxy added to the bottom to glue it permanently in the correct orientation. If anyone wants a custom wood knob, DM me and I'll share the wood maker's info (although you'd have to source the shift pattern plate yourself).
 
if you guys can figure out what font is used on the knob i already have the cad made for a larger 51mm OEM style knob.

Found it!

can get these made asap.

It's not a font really, it's the effect of an engraver. I have it as a vector file if that would help. Can you make this out of wood?
 
So what's your method for making sure the numbers align? Will you have the set screw? Also what's the difference in size from the stock ball?
Its an exact replica of the OEM knob. The only difference is the diameter of the knob 51mm vs the OEM at 46mm. same thread lengths and same set screw, and location.

New owner and member here but I'd be in for one of these as well depending on pricing. Also agree with crestima, I'd personally prefer it in aluminum to match the OEM finish.
 
I'd love a bigger shift knob but steel or aluminum bear the same problem as OEM - becoming ice cold in winter.
Wouldn't mind the set screw though.
