These machines are currently missing entirely.

I wonder how much demand there is for these?

I certainly noticed them missing. And then came to github, and aha there it was.

If its too much trouble its probably fine to omit. I found them useful.

Not too much trouble, no. They will be going back in for the beta release, hopefully.

Started work on this one.

Electric Compressor & Pneumatic Generator are back in the mod.

Note: lacking the fancy models they had in 1.7.10; they have simpler cube-based models for now at least. Will need a more skilled modeller than I to restore the 1.7.10 appearance...
