My Stock Pot to Copper Conversion.

The Starting point was this, a Huge 38 Litre Aluminium Stock Pot:

I had this welded up at work, made from a 1/2" BSP Stainless Steel barrel nipple from BES and a 3mm thick M22 Stainless washer from Stig's Stainless Steel Fasteners:

The 1/2" BSP Female-Female Ball Valve came from BES and 1/2" BSP-Compression Elbow was from B&Q, there is a brass 1/2" BSP Female-15mm Compression fitting with another M22 washer on the inside of the stockpot holding the Tank connector in place:

My Home made Hop Strainer (Hop Stopper), can drain down with a bit of a Pan tilt to 1 litre of dead space (*To be improved):

Outflow from the boiler via a piece of 15mm copper pipe (*slight redesign in order):

Plan view of a re-design idea (*which I won't need to use)

* Stuff marked with a star / asterisk:
The first drain down of the pot left about 1 Litre of liquid and I had to tilt the pan to get it to drain that far. I did some reading up and started looking into the 'Syphon Effect' and decided to stick some electrical tape over the top two thirds of the strainer (the bottom third of the holes are left open) holes and also reduced the internal diameter of the outflow pipe with a bit of PVC tube stuffed in the end. I did the same drain down test and found that it not only drained down faster but also only left 75ml of liquid in a level pan, no tilting necessary!
Now I just need to get a 15mm-10mm copper reducing fitting for the outflow pipe and solder up the top two thirds of the holes in the hop strainer. I'll also drill some more holes in the remaining bottom third to as to keep a good open area.

Can't wait for the next brew day now :) I can't help but think that I could half cool the wort via the outflow pipe now too if I just did a bit more coper pipe bodging and turned it into a counter-flow chiller!

My modified hop Strainer section, holes just in the bottom third of the tube, makes use of the syphon Effect:

Love the barrell nipple idea pdtnc, tidy work all round :clap:
I reckon someone could make a tidy profit selling those converted nipples as bulkhead fittings :hmm:
 
:) It was actually quite good fun once i figured out the syphon effect thing and got it empting down to the last splash! :)
