I've been a huge fan of this sight for a while, but I've only recently started to post. I am working on a HERMS unit, and this is the sight gauge I am building for my Boil kettle and HLT.
It's really difficult to get a good photo of this with my Iphone camera, but it looks amazing in person.
This is just a prototype... I'll be making 2 more for my kegs that will have 4 rods instead of 3 and a few other tweaks.
It's made with thick high temp/pressure 1/2" Glass tube... everything is stainless steel except for the post, those are brass. But the final one will have 4 stainless steel 1/4" rods (I believe)
Anyway, give me your thoughts on this sight gauge... If people are interested in having one made, I will post the final design and maybe a video.
