So it looks like Spring before Gumby79 and I can pull the trigger on DARKO.
The weather has severely shortened the number of days each week that I can work at all,and the days I can allow only a few hours to do anything.
Mountain passes are already being slammed with snow.There's no reason to risk anything.
I'm making slow progress and will keep at it until I'm 'ready',and only then,check with Gumby and DARKO to see about scheduling.
I have zero confidence that I'll ever be able to adequately predict how long it will take to fabricate anything!
