Hi all, sorry if this is the wrong category.
I have a Shizuoka ST-N knee mill in beautiful condition that I've converted to modern control. Unfortunately it lives in a woodshop so I have to use water based coolant on it, and if I'm not religious about wiping it down with oil each use the iron bed gets rust spots.
I want to put aluminum tooling plate on my iron bed and leave it there, but I'm worried about corrosion underneath. What should I do?
I have a few ideas I'm considering but I want to get your opinions because, aside from foolishly using water as coolant, my problem seems like a common one. My thoughts:
The zinc seems like the most robust solution if it would work the way I'm imagining, but like I said this must be a solved problem in the community so I'd love to hear what others have done. Thanks!

- Put a thin plastic layer under the tooling plate and plastic washers under the mount bolts to prevent a corrosive circuit forming, and keep water out from under.
- Use a thick coat of grease instead of plastic, and just check on it every week at first to see if anything's corroding.
- Bolt sacrificial zinc blocks to the underside of the tooling plate in the bed T-slots to protect the iron?
