Drove by the paint shop today. The engine- and clutch covers were'nt finished, but he was actually working on it. When I took them off, they all had minor scratches, and the generator /points cover L.H side even had some dents. He's doing a great job, and I'm sure they will look brand new when he's finished.
I have always wanted to able to measure piston TDC exactly, and I also prefer to adjust the iginition setting according to piston position before TDC, rather than fumbling with a clumsy degree wheel.
As I will be doing the ignition timing in a not too distant future, I bought this on Fleaybay:

.. from Poland, I think. Cost me like 7 USD plus 6 dollars in shipment.
It's very well made, solid and with a good finish. The thread is 14 mm, same as for the spark plugs, and it fits nicely.
But I wanted to get rid of the ruler...

.... so I can mount one of my Dial-gauges...
Next step was to drill a 4,2 mm hole, perpendicular to the large tube , and cut a 5mm thread. Then I milled away some of the metal in the top:


In the 5mm thread I fit a little Allen screw, just to prevent the dial gauge from moving.

I had an extra extension tube for the dial-gauge. It needed to be shortened a bit, and I rounded and polished the tip of it, so it won't scratch the top of the pistons.
Finished:
Did a quick try, and it works great. The hole process took me 'bout 40 minutes.
It's a great satisfaction to be able to build your own tools, even though you havn't started from scratch.
More updates during this weekend, so stay tuned
