Hello Fellas, GGBG here.
I have done my own research to no avail and was curious how others (if at all possible, neatly and safely) feed wire through a curved surface (chamber) and have it sealed. I know there are cable grommets but they aren't curved and to my guessing they won't seal unless screwed to a flat surface.
Also my chambers are steel.

I've drilled holes and fed wire through an aluminum chamber and used epoxy to seal it. It's been 12 years and it still works. Another more recent cannon I made uses a spark plug. Drill and tap a hole and stick a spark plug in there. Well, the spark plug went through an end plate, not the chamber. But a spark plug might still work depending on the thickness.

Thank you for the suggestion, I'll definitely go with the metal epoxy.
And I will be upgrading the cannon over time but for now it'll just be a base model that operates and build onto that. Spark plugs will come in due coarse. :)
I did not occur to me I could tap into a cylindrical wall.
