Great photos! Thank you.
So... *deep heavy sigh* ... it looks like there is a different problem with the replacement main shaft that we picked up. From what I can gather they are all out of replacements. Berg is going to have the machine shop machine a new one for me. Unfortunately it's going to take 3 to 4 weeks. In Berg time... that's easily 2 more months.
I'm going to call Tim on Monday and see if we can figure something out. I may (oh the irony...) just go with a Weddle shaft and 1st/2nd gears. Yes... more money.
Maybe Berg will refund some money on the main shaft they ruined?
*grumble*
