Me: Commodore 64 and Commodore 1541 repair. Various broken 1541, at least 2 working 1541, soldering iron, 1541 speed controller, and if I can find a disk cleaner kit.
You: ?
I will bring 1541 focus things. I have some good useful gear for this topic. b
Bringing various tools, soldering iron / meters / part supplies / scope / resocketing tools etc.
I've never dived into 1541's, or done any alignment, will want to get involved in some of that.
So, I'll bring a mix of working vs non-working stuff.

As far as 1541's go, what I will start with is a few working drives. I want to set up some measuring equipment so we can take baseline readings of the electrical characteristics of the drives. Then with this info we can play doctor 1541 to diagnose non-working drives. We can line 10 drives up at a time, probe targeted points and determine which are the best candidates for repair. We can also swap parts, etc. I have an oscilloscope but if anyone wants to bring a better one, please advise and I will leave mine at home. I am also planning on bringing a few DEC power supplies to test out. h742a's. These are 115V and can be tested from a regular outlet. I have restored one from the grave, I hope to be able to bring up at least two more (I have 4 to be restored). Restoring the supply was a great learning experience for me, I was totally clueless about DEC repairs before I started. I know VCF has at least one h742a power supply in the store room we can take a look at, maybe diagnose the condition of VCFs pdp 11/40 power supply. Bill
