skype mtg went fairly well. 4 guys but for an unknown reason, I as the session initiator, I did not see the pix of 2 guys though they could see me? audio worked OK for all.
2-1/2 hrs and a variety of technical issues covered.

Erich as to your ?
On the right is the commando (28tpi) 2 stem nuts, 1.295" across the flats.
The wrench is 1-5/16" water pump/aircraft wrench It is thiner than the nut hex.

On the left is 2, 1.390" hex nuts. in the jaws is a featherbed nut (26tpi). The other is a larger hex commando thread nut. A 1-3/8" wrench fits both , but snug.

Thank you Dave,

I was going to attempt to grind down a standard wrench, but was unsure how its strength would be affected thinning it down enough to fit. I will look out for a water pump/ aviation wrench in the correct size. It will be a good tool to have on hand for the earlier Series 1 bike.
