Couriers have just dropped of £160 quids worth of Stainless fittings and copper tube from BES . . . . The plans for the femtobrewery move closer to reality :party:
 
Nice one.

We should try and get discounts from them for THBF and Jim's members. I've spent a fortunte there lately.
 
:oops: :oops: :oops:

Vossy, you provided me with the details of the supplier for the John Guest fittings for the sight gauges. . . . Unfortunately I can't find the post/PM with it in . . . With the BES Parts I'm getting close to being in a situation to start cutting and drilling . . . Could you send it again please
 
Just for fun I went for both :)

The femtobrewery is going to be all 3/8" and 10mm , and the picobrewery is all 1/2" and 15mm

No particular reason apart from the fact that I have already cut the holes in the picobrewery kit (HLT, and FV) I just want to replace the plastic parts with shiny ones

I can remember the JG Part numbers its just the supplier details I need :oops:
 
Airflow compressors have just dropped off the JG Fittings for the 12 Sight Tubes :shock: Yes 12!! . . . can recommend this place . . . just a strange way of ordering, but it works. Ordered Tuesday delivered today . . . Great.

Need to order the PRTD's from Watch Hill (Another 50 quid :evil: ), and I'm waiting delivery of the thermometers for the Mash Tuns (one at 24.5L and one at 80L :D ) From Thermometers Direct

And get some hole saws :hmm: not sure about that . . .

Femtobrewery constrcution soon to commence :party: :party:
 
Watch Hill have been as good as ever . . . 2 200mm PTC100 probes delivered today . . . . along with 4 SS glands . . . Nearly got everything I need :party: :party:
 
So you'll be needing a couple of encapsulated PHE's soon, then...... :whistle:

Unfortunately other commitments always seem to be cropping up at NCB meeting dates - I was travelling back from Cornwall last weekend!

I'm going to be heading over for a weekend on the lash in the Warrington area sometime in May if that's any use.....
 
No worries Ian . . . I'm looking at all sorts of cooling options anyway and the PHE's are just one of them.

However courtesy of Chandlery World I now have the worlds biggest nipple (That's a 38.5L Thermobox in the background)
bignipple.jpg

Its a 1m length of 3/8 BSPP tube, which I will be able to cut to length to make my custom nipples, and then at a later date find someone with a CNC lathe to custom machine me some in stainless . . . . It's a bit of a cop out and compromise, but I want to get this brewery built, and used
 
Nice nipple :P
Nero do stainless nipples, standard 1" £2.92 inc vat and made to measure.
I've had some 40mm ones made. The are quite good for certain things, cheaper than BES, but can be slightly more expensive on others.
 
I can't believe that I started this thread back in March :oops: and have only now got around to actually drilling holes in the Thermoboxes. Anyway the first task was to fit this 3KW Swan boiler element (15 quid from a Blackpool based eBay seller - No longer registered) into the base of the thermobox (38.5L From Nordic Optical)

ThermoboxElement.jpg


The first step was to measure the distance from the inner wall to where I wanted the element to fit . . . which was deliberately off centre to try and encourage currents to form. After adding the thickness of the wall it was time to measure and drill a 6mm pilot hole.

MeasureDrillHoles.jpg


Oh and can I say if you are drilling holes in stainless go out and buy yourselves some cobalt drill bits . . . I use the eBay Seller UK Drills, and it is difficult to beat the Bosch Cobalt Hole saws from eBay Seller Hendroid

After drilling a 6mm pilot hole all the way through the outer and inner skins of the thermobox . . . time to break out the hole saws.

6mmPilotHole.jpg


On the outer skin I needed some room to work so decided to break out the big 64mm hole saw. Despite taking it slowly, using cutting/broaching oil, and using a lot of pressure, I still managed to work harden the stainless . . . and burn out my old black and decker drill (which I'd had for 21 years!! . . . excuse to buy a new one :party: ) . . .and decided to resort to my new Makita Cordless . . . Which quite surprisingly made short work of the rest of the drilling.

And the thing cleaned up really easily . . I cut out the foam with an xacto knife, to remove it

64mmHole02.jpg


For neatness I prefer to use Q Max punches to make bigger holes (From Rapidonline), here I am using a 16mm punch to make a larger hole for the bolt for the 40mm punch I need to pass the element bits through . . . Oh and a simple piece of advice . . . get the thrust race for the larger punches it makes life so much easier.

PunchInnerHole.jpg


The element is held in place by five metal studs spaced around the circumference of the main hole (This also secures a rubber washer to make the thing waterproof.) After hearing about all the problems Vossy had when he was drilling this sort of hole for the drain in his mash tun I was somewhat apprehensive . . . still Fors juvat audentes

SecuringHoles.jpg


I had marked the position of the holes using the rubber washer, punched them with a centre punch and then drilled them using the 4mm cobalt drills . . . hot knife . . . butter, and here is the element fitted into place.

ElementFitted.jpg


Still it is a tight fit to the connections in there . . . :hmm: do I want to use the boil dry cut out :hmm: Of course I do, so fitted the straddle wire between one terminal of the element and the live of the cut out.

ElementConnections.jpg


And then made all the connections . . . The cable comes in from the side, via a cable gland, which stops a lot of water ingress, and is 2.5mm cable rated for 'hot' environments . . . I would suggest rubber cored instead of plastic, if you can get it use immersion element cable.

I will once full testing has been completed be securing a stainless plate over this hole probably with pop rivets, and a silicone sealant as a gasket . . . for the time being it is left exposed. I mentioned earlier in the thread that I had obtained some PT 100 sensors and glands from the sadly no longer with us Watch hill, and these were the next thing to be fitted.

TempProbe03.jpg


After drilling a 6mm pilot hole about a third of the way up from the base of the inner skin . . .I then switched to a 25mm cobalt hole saw and made a working hole in the outer skin.

TempProbe01.jpg


ANd again quick work with the xacto knife soon had the inner skin revealed . . . where I had to drill a 10mm hole for the thread of the gland

TempProbe02.jpg


And with a short bit of filing to clean up rough edges here it is.

TempProbe04.jpg


I have a sight gauge to fit, but that shouldn't be too hard . . . and a tap to do . . . but a test using the original tap at least proved that the element worked :lol: and the seal around the element didn't leak . . . . The same couldn't be said for the stainless gland, But I had cut the O ring doing the securing nut up too tight . . . I'll add an M10 stainless washer on the inside with a smear of food grade silicone sealant, and will then not need to do it up as tightly.

Next up a 38.5L thermobox boiler
 
I'm not sure whether you enjoy building breweries or brewing the most :wha: :lol: :lol: :lol:

Very nice, neat work Aleman :thumb:
