I really like your setup. Had a few questions about your dip tube and whirlpool arm from Jaybird.
Do you recall what the dimensions were of this dip tube before you cut it?http://www.norcalbrewingsolutions.com/store/Tri-Clover-Dip-Tube-1.5-Inch-x-1.5-Inch-x-.5-Inch.html
Standard length is 3 inches and standard height is 3 5/8
What did you use to cut the dip tube and at what angle did you cut it?
Also for the Whirlpool arm you stated the height was 10 inches, but do you recall the length? ... 2 1/8 is the default.
I am looking to design something similar so any help on the dimensions would be huge.
What I am using as the diptube is actually the NorCal whirlpool return so it is 2 and 1/8" long not the 3" that comes standard with the TC "diptube". I ordered it 5" tall then cut back and inch or so, then cut the angle to match the kettle bottom.
I cut this with a little hand hacksaw and a dremel tool. Worked well enough.
The whirlpool arm is 10" tall and the standard 2 1/8" long. This length hugs the kettle wall nicely.
Hope it helps!
