I recently got a 15.5 keggle from AIH and I'm wondering how I could provide markings for my liquid volume other than a sight glass.
I've seen some ideas about marking a mash paddle or a flat tip punch. Does anyone recommend any of those methods or does anyone have a better solution?
If you have this keg style 5, 7.75, 10 are marked by the bottom rib, middle weld, and top rib
Paddle / spoon marks on a keggle rely on hitting that small flat spot in the bottom.
I've seen people etch the inside with DIY etching made from a 12v battery charger. There is a trick to the masking using stickers and nail polish. Worth a Google.
This is a pot done with a 9v battery. http://www.homebrewtalk.com/showthread.php?t=463099
