Yes, your thread inspired me (after reading through those suggestions) to create this thread!
Shoot, I even went out and researched what might have lower surface tension than acetone (plus ATF), but I have not had a chance to see if any of those other potential solvents are available to the general public...
Thanks!
BTW, any luck on your end? :-)
No, the machine has been in service almost continuously since I posted the thread. I had to block out next weekend on our business calendar so I can get at it.
I've got some Mouse Oil coming via Amazon, and I picked up a can of PB Blaster to lubricate the screws, prior to tackling the disassembly again. I'll let everyone know how it goes.
