Crap Welds and Selleys Knead It!

by **karrotbear** » Thu Jun 06, 2013 7:18 pm

Hey all,

So, from what I have demonstrated in previous posts, my worksmanship is second to none - yeah right!

So I have 2 x 50L keg boilers, both with 2 x 1" sockets for screw in parts. My welding is shocking, just so's you know. I decided to grind all my old welds back (because when I was running at 4.8kW every small leak turned into a fire hydrant) and redo the welds, only ended up blowing bigger holes in my damn kegs! So I went to bunnings and the paint specialist (remains to be seen) dude recommended that instead of just siliconing the holes, that I just get this Selleys Knead It - Aqua. It is apparently water safe (for tems between 0 and 85 with a certian surface area per L exposed) and operates between 120 and 140 degrees as max temps.

I slapped this mix all over my welds and forced it in. Just wondering if anyone else has used this before, if not I will post results eventually !

Big roll of the dice if you ask me dude. Flour paste is at least edible...

The guy is a paint specialist. :wtf:

Why not use some staino scrap pieces and weld them over the holes if they are that bad? At least it would be food/alcohol safe.

Don't try running a bead with thin staino, just use a series of tacks.

Tried it on my boat once, didn't fix the leaks :handgestures-thumbdown:

And yeah, fuck knows what crazy chemicals are used to make that gear :scared-eek:

Yeah I would not be using it personally. If you can't get your welds to seal, patch them with soft solder. That's what I would do.

Awell, it's done now anyways. Waiting with baited breath for the virus ridden tongue bt1!

I did a bit of research before I smaked it on. Some people in america use it to seal their dunderpits and crap like that. So I figured I'd just try and see. Only a 30$ investment if it goes south, vs ponying up the money to get a firm to tig it all for me.

These boilers were going to shit anyways, and I have been meaning to get a new CUB + new sockets + 4" sight port, so this is just the push I need :)

So I have 2 potentiall issues now, I am going away on work for 2 weeks and my total reimbursement for the travel etc is pretty damn high. I can either spend it on a new boiler, or I can spend it on getting all my parts for the bubbler I want to build. Or just chip in a few extra hundred and get one of the FSD rigs. But I want to build it (keeps me busy).

Does anyone know how much it would cost to get a firm to do the 2x 1" holes, 1x 4" hole and the associated welding?

This is the bit I'm concerned with mate.

It ain't a $30 investment at all IMHO. Your health is worth a bit more than that.

If you drilled and cleaned the holes on the keg, it would could fark all for a shop to weld it up for you.

Just think about it before you use it mate.

mate on your boiler come on... :teasing-tease: my advice to you is, remove that stuff and sort out that keg properly, after all for the sake of a couple of dollars is your life worth it? Kegs although not pressurised (unless you block the vapour path) contain very volatile gases once it reaches temp and need it's design integrity to perform properly so you can distill knowing that you are following safe parameters that have been used time and time again..I urge you to remove this stuff in fear you might if unlucky pay a very high price for the decision to use it... not to mention what it might leach into your end product....ewww.....imo.

Paragraph 10 mate.

MSDS

Don't use it. Don't promote it on here if you do.

Cheers

Yep! that should be enough to discourage anyone from using it, not even close to "fit for purpose" ;-)

Keep yourselves safe guys :handgestures-thumbupleft:
