Welded Element Boiler Fitting

[cat herder]

I'm ready to start putting my boiler together. I need to drill holes for the elements, but before I do that I need to know how big to drill them. Do I drill them the inner diameter of the fitting and have the fitting welded around that hole, or the outer diameter and have the fitting welded within that hole? In the end it should look something like the pic, but a larger fitting ( ignore the penny).

Use a 2 inch ferrule with a Stilldragon element cover. Never look back.

There are lots of places to get element enclosures and instructions on how to prep the holes. I went with 1.5 inch TC but that is what my brewery uses so that is why

Look at Brewhardware. I am not affiliated with them, but shops there often. Bobby has some nice videos and tutorials on his YouTube page

I drilled to the o.d. Figured if you drill to the i.d. you would have to shape the fitting to the curve of the boiler.

I'm waiting on the Still Dragon element cover to arrive. I really like the looks and build of theirs.

I went with the Brewer's hardware 2" element housing and it's REALLY nice. This sucker looks like it's machined from solid bar with single point cut threads.

Best way to do round holes in kegs are greenlee cutouts/punches. Perfectly round and smooth quickly. Used a greenlee for my 2" ferrules on the side and a dremel to cutout my 4" top ferrule. But my ferrules were silver soldered onto the keg using Harris Stay-Brite 8 and liquid acid flux... not soldered.

I have one of each, Brewers Hardware and SD in 2". You can't go wrong with either one.
