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 at www.jimsbeerkit.co.uk 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:
2nd Extract brew – Bramling Cross IPA 🙂
This time its a 12 litre brew, so more than a demijohn full like my first extract, this time its in a new small 15 Litre FV bucket which is a nice manageable size for lugging up and down the cellar steps!
This was a real test for my stock-pot conversion to boiler (I should blog the details) 😉
Malt Extract Syrup Pale – 5.5 EBC – 1500 grams
Dried Malt Extract Pale – 10 EBC – 390 grams

Roasted Barley – 1350 EBC – 20 grams
Bramling Cross – 38 grams – 60 Mins

Final Gravity: 1.012
Alcohol Content: 5.1% ABV
Bitterness: 61 EBU
Colour: 31 EBC
Bramling Cross Hops:
First batch of hops gone in, grain bags bobbing around:
Run-off from boiler into FV3, which was cooled in the bath:
Yeast Starter, the Safale us-05 was mad-for-it with loads of fine bubbles:
Hydro @ 35 degrees, apparently its really about 1044 (6 or 7 points below where it should have been):
15 Litre FV tucked up to bed:
Things I’d change:
The way the boiler drains off through the hop stopper could be improved, I’m thinking a short curved copper pipe.
The Linen bags for the grain are a little watertight, though they did their job, I shall have to search for muslin bags 😉
Immersion cooler wouldn’t go a miss!!
I maybe wouldn’t rinse the hops with as much liquor next time so as to keep the right gravity, I should have checked the hydro in the FV and adjusted after 🙂
Bottled 6/5/09 with 50g Dry Spray Malt instead of sugar @ FG 1010.
It goes like this:
Hop Back Entire Stout – 5-Litres
- Dried Malt Extract Pale: 725 grams (Actually used 500g Light DME and 225g Medium DME)
- Crystal Malt: 32 grams
- Chocolate Malt: 32 grams
- Roasted Barley: 32 grams
- Black Malt: 18 grams (not called for but I needed to up the colour with something)
- Challenger: 90 mins – 10 grams
- East Kent Golding: 15 mins – 4 grams
The Spray Malt Dissolved:
The Colour Change after Grains and Hops added, nice boil going on:
Used So4 yeast
- Final Volume: 5 Litres (actually got abot 4.5 L)
Original Gravity: 1.055 (actual OG in picture below)
Final Gravity: 1.015
Alcohol Content: 5.3% ABV
Bitterness: 41 EBU
Colour: 171 EBC
Got a bit less than I wanted and nearly 10 points higher gravity, wonder if it will go off like rocket through the bubbler!

*The morning after*
*Bottled today, 18th April 2009*
Original Gravity (OG): 1066
Final Gravity (FG): 1020
Alcohol Content ABV: 6.04%
After a sneaky little taste while bottling it tastes quite sweet, looks like a different yeast might have chewed through the malt a bit better, but 6.04% is pretty fair. I just hope my 1/3 Tsp priming sugar has enough viable yeast to carbonate.
Just a quick note to say that my Mostphotos.com portfolio is now deleted.
It seemed a waste of space, I rarely checked the site and never sold anything, better to delete my account. At least Yaymicro has sold 1 image.
This might be the next camera 🙂 HD video sounds interesting for the occasional stock footage creation. Shame it doesn’t quite get to XXL size at istock though.

March was different, I made my average cashout level but just missed out by a day or so on cashouts from iStock and Dreamstime, for the first time in a while SXP did not reach the minimum payout figure.
Here’s the Lookstat graph for March:
Next up here’s my monthly cashouts graph over time, after reading things on Microstockdiaries regarding some slowdown, so the graph below kind of backs that up showing me that earnings for March are as good, or bad, as they were over two years ago. August ’08 being my best month ever, its looks like a gradual slide downward now.
This is backed up my blog views at imagepushing.com , the first graph in weeks and then months after shows a slump in views… meanning less designers, artworkers, and buyers are searching for images
What I need to do is to start being more targeted in what I shoot and submit, if only to improve my approval ratings a little!
Its a short report this month, more in reaction to Lee’s over at MD to see if there was any correlation.
