I would remove that oil pump drive worm gear, too close for comfort.
You still want some plywood under that cardboard...
28# is my guess.
Do you think Redline 20/50 will be OK for those new style bearings?
Looking good. So what was the all-up weight?
I have shipped lot of tube amps. Heavy iron transformers and some of them pretty much a two man lift. I would be nervous shipping that. Roll some cardboard into tubes and pack around the cases cuz they look like they'll move. The tub is great idea. But it looks like the case is in direct contact with the top, which might not be so great.
I assume you insured it for maximum value?
