My (Re)Build Thread - Kal Clone-ish

SilverZero · Jul 19, 2015

In the beginning, there was propane. Then I added an element and an SSR-V controller to my kettle. Some time later came the electric keggle, pump, and a lot of valves.

Finally, the time has come to rebuild my brewery. I'm moving into a new house so I'm going basically from the ground up. I've got three stainless kettles on the way, a shopping list of fittings ready to order, and a box full of components to put into my control panel.

Today, I start planning, measuring . . . and drilling!

Step 1: Unpack, decide on the best layout, and math out the spacing. I ended up going through a few variations before landing on basically the same layout Kal and everybody else uses.

Measuring the horizontal spacing:

I measured in 25mm from each edge to account for the weatherstripping on the inside of the door panel, then marked off 40mm more from the right edge for the door latch. I divided the remaining space into 5 columns at 53mm with 10mm between each column.

Next comes the vertical spacing:

Same 25mm from the top and bottom edges, then divided into 6 rows at 46mm each, except for the third row down which is 54mm (PIDs require a bit more space). 12mm spacing between each row.

The preview:

That fourth PID on the right is just a placeholder until my timer arrives tomorrow. I had three TA4s but I decided to get a TD4 for the boil controller, for the manual mode.

I'm heading out to the shop to mark my centers and start drilling this afternoon.

Rearranged a bit on the power switch and meter. This feels less cramped on the top, if I can bring myself to put that meter across the middle of two columns. I have problems. Feel free to vote.

SilverZero · Jul 19, 2015

A step bit and a drill press made short work of the 22mm holes for the lamps and switches. I was lucky and found a step bit that maxed out just a shade under 22mm, so I could run it all the way through the panel and know that I wasn't over-drilling. Started it all with a pilot hole, of course.

A second pass with my larger step bit to take it one notch higher (7/8") and it was perfect. I even ran it just up against the next step from both sides of the panel to strip off the burrs and edges. Pretty close to clean and smooth with very little work!

Oh, and one word of warning: Don't get overzealous and start drilling before you've taken out the ground post on the inside of the panel! Mine was right on the edge of the top-left hole. It jammed me up a bit and caused a bit of deformation on the metal, but it'll be easy to straighten out.

No major screw-ups so far. Now to attack the square holes for the PIDs and meter.

Ha im going through the same thing, bought a new house so i sold my Rubbermaid tun, keggle and propane burner.

Got 3 20G Concord kettles and everything i need to build them up, except im going the StrangeBrew route rather than PID.

I too drilled a hole without looking where the post was in my box and it ended up being right on the very edge of the hole. So now i have to be a bit creative when screwing my grounding cable to the post because the nut to hold the switch from the backside rubs up against it, but it should be ok from some test's ive done.

Haha, kindred spirits.

The worst part is that I knew the post was there, I just got carried away and forgot to cut it off first.

I saw you had moved and were active in the SBE thread. I played with it, got a Pi, got some probes, but I already have all of this gear so I decided to go hardware. I gotta PM you when I'm up in your neck of the woods, I'd love to meet and see your setup when it's done.

SilverZero · Jul 20, 2015

Whew! A long evening of trying to make a square hole out of a round one. For better or for worse, I decided to do the bulk of my drilling with some bi-metal hole saws I had around (thinking I'd be grinding down to the corners). The meter is rectangular, so I did two large-ish holes for that. I found a 44mm hole saw that is just perfect for the PIDs and timer, so I blew those ones out with that.

After hunting around for the right tool, I finally found a pneumatic metal saw that was AWESOME for getting the sides straight and cut to the corners. Basically a small high-speed Sawzall that runs off compressed air. I still cut conservatively and had to spend about an hour of quality time with the hand files, but I got some pretty straight edges out of it in the end.

Couldn't wait to fit the pieces in!

And a rear view:

I still have to file out some space for the tabs that hold the meter in place, so it's not quite fit yet. Easy job for tomorrow, but I'm beat and I need some sleep. It's coming together! Tomorrow I'll get the meter mounted, probably get my timer in the mail and swap it in for the "real" look, and start thinking about the receptacle and connector options for the bottom of the enclosure.

did you put together a list of the fittings you will need and the prices etc?

I am trying to build mine as well but from a distance. i hoping when i return home to start building but my internet sucks right now so price checking is tough!

I've got bits of lists here and there, but I've been collecting pieces over time as well. I'll probably put at least a parts list together sometime. I buy and build in stages. It helps to keep my spending less noticeable.

I'm actually going to have to stop buying for a couple of weeks unless I can sell my old 3-vessel electric setup. I've got it on CL but no bites. Maybe I'll list it here in the buy & sell section.

Ditto, we crash out at the inlaws in Sun River a few times a year, next time Thanksgiving which probably wont make the best time but eventually

FWIW here is the spreadsheet i made for my current EHERMS build using welded fittings you can possibly use for yourself. It has the best prices i could find, i made this so i could make sure i forgot nothing and didnt have to pay for shipping multiple times. I think its pretty well laid out and explains what the fittings are for if its not obvious. There's tabs at the bottom for every vessel, as well as the first tab which contains everything so it was easier for ordering. The misc other tab i never really filled out, but was meant for tubing/camlocks, pumps, etc.

That false bottom costs a pretty penny. Surely you could make one for a fraction of that cost and have the same functionality.

I haven't looked at this price list, but I know I'll be making my own out of a stainless pizza pan for the BK and the MLT. I hate depriving the good folks here of a sale, but some things I have to DIY. (Or... DIM?)

One that is precision fit, with secondary side filtering and can withstand 30-40# grain bills and not collapse or get constantly stuck for 10G batches? Not really unfortunately.

Besides, i saved probably $800 in buying cheap concord kettles instead of a premade Spike or Blichmann or something, i figure why not just spend a bit to get the best false bottoms out there?

I had my metal fab friend(who does my welds) price me out at about $80 in metal, not counting his work to actually make one or screwing it up somehow. I'd rather pay the extra $30 if it fails or was sized wrong i could just send it back to Jay lol.

Not to mention with his 20% off Fathers day sale it wasnt really as bad, buying all my fittings from him i saved like $80.

If i wanted to save $$ i would just buy the cheap 12 inch one that sits on the bottom and hope it doesnt lift up during stirring and make my own copper HERMS coil, but not this build, im tired of upgrading later

BrunDog · Jul 20, 2015

I gotta say my NorCal FB is built like a tank. Will definitely outlast the cheaper bayou pot it sits in.

SilverZero · Jul 21, 2015

Made a few more cuts today for the receptacles. I also got some primer and paint but I'll still need to cut holes on the top plate for the SSRs and heatsinks before I can do that.

I decided to mount the 120v pump receptacles directly to the enclosure. All of the others will be either 24mm XLR females (temp probes) or Switchcraft HPCPR41F connectors, also 24mm. It's nice having all the same hole sizes.

Shown is an HPCP41F in one of the probe holes. The "R" versions are about 60mm across as far as I can tell from pics online. I'll use these for the main power in and the element outs.

I'll be traveling tomorrow for a job interview (wish me luck!) so I probably won't make any more progress until Thursday. If I can track down some heatsinks I'll get the top plate measured and cut, and hopefully primed. I should have it painted and ready to start assembling by the weekend, and by then I should have my Concorde kettles to play with as well.

I bought this
http://www.amazon.com/gp/product/B00N419ABM/?tag=skimlinks_replacement-20

It fits two SSR's comfortably and at that price its pretty amazing.

IMHO there's no reason to mount your 120V SSR's external but if you wanted to you could just put two of these side by side with a bit of silicone between them.

That said you need to be able to tap your own holes, i just went to Harbor freight and bought their cheap $20 metric tapping set, drilled a few 3/32nd's holes and tapped them and screwed in tiny M3x0.5 bolts to hold my SSR's and the sink in place.

For $28 assuming you dont have the tools yet for a heat sink its a pretty killer deal. Tapping sets are good to have around anyways

Also found this i think that should fit 4...you'd want to measure your SSR's of course but it should have ample room.

Nice, I'll check those out. My plan was to harvest a couple of PC heatsinks but I'm flexible. I do have a tap & die set.

I bought my heatsink off eBay for $16 including shipping. I got lucky with the threads, mine had 4 small threads that for the 2 ssr'a perfectly! The seller had a bunch of heatsinks for sale. Here is another one

the $40 bayou false bottoms have been redesigned and are now stronger.... just a heads up for those using bayou kettles... I use one and it works and seals well against the rim designed for it.

SilverZero · Jul 22, 2015

My 3 Concorde 80qt kettles arrived today. They're huge! Now to start the arduous process of working up the nerve to put a bunch of holes in them. Any advice for valve placement? I'll be doing the BK and HLT identical (doing an external HERMS solution) and then the mash tun will have the upper valve near the top.

FuzzeWuzze · Jul 22, 2015

Yes they are quite big pots! I too am dreading putting holes in my pots. I cant decide if i want to drill them out with my step bit, or just buy a greenlee on ebay and then resell it after.

I have something like 9 1/2" holes and 2 big ass holes for my 2" TC Ferrules to get welded on. Seems like a gigantic PITA to drill all those out, if my step bit will even last 9 more holes.

I keep wanting to go TC for my elements. I think I will, but I don't want to weld (because I don't know any welders and I don't trust my novice skills).

gwaugh · Jul 22, 2015

I'm in the build process myself and am going with the same pots. I am thinking I might use TC on the boil kettle for the element, haven't decided for sure yet. If I do I'm planning on silver soldering using the radius fitting from brewhardware. He's got a pretty good how-to video and it doesn't look that hard.

FuzzeWuzze · Jul 23, 2015

Yea i'd go for the 2" Solder flange setup from Bobby at brewhardware. I only went welded because my buddy can do it.

IMHO you need to be able to remove your element to clean your pots properly, can you imagine trying to lug around a pot with a giant ass box coming out the back and heavy ass 240V cord dragging around everywhere? Seems like a giant PITA, when cleaning sucks already i want to make it as simple as possible to take things apart and soak them and be done with cleaning

You could also do the 1.5" flange but i went with 2" so its a bit easier to get a ripple element in and out. As i understand it with 1.5" TC you have to wiggle the pot and element around to get it out past all the curves in the ripple element.

No but i can throw one together? But im doing a Strangebrew box, not a PID one.

Also if your looking to save money, wait until a holiday and then check the Vendor forum where they post their sales. I got 20% off pretty much all my fittings and false bottom from Jay @ Norcal and saved like $100.

You're right. My current 10Gallon pots are like this and it is a major PIA. I just leave them on the brew stand and drag a high temp hose that I have connected to my faucet and clean them in place.

I'm upgrading to 10 gallon batches and I'm having Spike brewing custom make new kettles and I went with the 2" TC fittings for the elements to avoid doing that and I purchased 2" TC blanks to be able to close off the element holes to clean the kettles without having water spit out of them.

gwaugh · Jul 23, 2015

I was thinking of only making the boil kettle removable. I can't really think of why I would need to ever move my hlt or why it would need too much of a cleaning. Any thoughts/experiences?

dmcman73 · Jul 23, 2015

No you wouldn't need to clean out the hlt as often but, at some point after so many brews you should to make sure there is no buildup.

I mean if your going through the hassle of doing it once, why not just do it twice and never have to worry about it? :mug:

I'd think doing one welded/soldered TC and then on the other one welding a nut or going weldless would be more of a PITA as you have to drill different size holes. Or just drill two 2" holes, silver solder that bitch and call it a day!
