For as long as we have had our car, I'd wanted to replace the non-standard wooden knob, a burr in line with the walnut burr trim, ok the best I could find was elm..
So..
How did it come about, the thread was M8, so having trued it all, drilled and tapped, what better drive..
the next..
just how deep the the burr...
remount the top and shape lower section...
missing a step or so here.. remount on tap and blend in the top, sand and finish...
the result fitted..
guess if I find a piece of
walnut, it will be making another..
