New take on dimpling, silver solder bulkheads?

[The_Bishop]

You could, but the male end is a bit on the long side. Might intrude into the kettle too far.

So, the whirlpool arm works well:

How long are these from tip to tip? Thanks!

Bobby - I just installed mine today and I think I am going to be very happy. I heated from the inside (not sure what I was thinking there) but it still worked great. My solder job doesn't look quite as good as some of the other pics, but I've tested with water so far and no leaks.

I started with a 7/8 hole (because that's what was already there) and it was still a nice snug fit. I improvised an install tool from a bolt, washers, and some big impact sockets.

Good to know the larger hole isn't an issue. I think 7/8" would be the largest. Otherwise you don't gets as much material dragged through.

Just finished putting together my lid mounted HERMs unit today. Turned out really nice. Had to order another $130 worth of hardware today because I didn't figure right.

That looks really freaking nice. How long did it take you to do all those bends

I wish I could take credit for bending that coil but it's the JaDed HERMs coil they sell. I had them add a little extra length onto the inlet and outlet tubes so that I could bend those upwards toward the lid and maintain the orientation as they are designed to use the standard mount through the side of the kettle.

When the lid is on, the coil sits about a 1/2 to 3/4 inch from the bottom of the kettle and fills up about 3/4 of the space inside so it should be very efficient.

My only concern is that it's made of 3/8 inch tubing rather than 1/2 inch and I'm worried about the flow since these bulkheads are based on 1/2 inch tube.

I can always change the coil if it proves to be too small, that's the beauty of building it yourself with Bobby's bulkheads.

Effing brilliant!!!!

Ahh. I stick by my assertion. It looks freaking nice, even if you didn't bend it. Lol.

I built myself a version of their cleanable counterflow cooler using 3/8 copper. Flow is definitely an issue for me. I decided just yesterday to rebuild it with 1/2.

Even if that coil turns out to have flow restrictions, it should still work good for immersion chilling.
