Made my own shifter knob

[ahlem]

On a related note,

Can someone confirm the thread dimensions are M14x1.5?

The insert is going to be custom made to keep the minor OD fairly small.

Here is the status so far. Tomorrow I will put the clear finish on. It took longer to make the threaded, counterbored steel insert than the wood part.

Walnut similar to gunstock material.

I can confirm the thread size is not m14x1.5 now that it's done and won't thread on.

I went back to the hardware store and checked. No m15x1.5. I will have to check my tool suppliers.

I hope I can drill and tap my oiled walnut shifter knob to the next larger mm without destroying the thing, it turned out beautifully.

You ever figure out what the thread was on the shifter knob?

[harold]

It's M15x1.5, which is not a standard size. I got a tap from ebay (sent China Post from China!).  If you  just tap the wood, and the grain is vertical, it won't work.  I made a cross grain dowel, epoxied that in, then drilled and tapped it.

I made aluminum inserts and epoxied them into the wood. I turned some small ridges on the OD of the insert and used JB Weld. It worked great. I sold the car a while back to a kid who wanted to make a vintage race car.

I also like to put a little lock nut onto the shifter rod on the bottom of the shifter knob to keep the knob in place and to take some of the strain off the insert from over tightening it.

I know this is a crazy-old thread, but where do you find an M15x1.5 locknut? I can't find one anywhere. McMaster doesn't even list M15 as a thread size for their standard nut assortments.

Just answered my own question. When in doubt, turn to eBay: https://www.ebay.com/itm/152664128706
