Got sent this by my fabricator today - finally! Guess I should be in the money early next week, just in time to run my first wash

Hey Yummy - I think the 200mm ferrule on top makes it looks smaller than it is - it should be 50L to the bottom of the conical top, allowing some headroom... unless things have changed jn the workshop

Posted: **Tue Feb 08, 2022 1:44 pm**

Well - all welded up, polishing to be completed tomorrow - ahead of time for my first sugar wash!

It was more the forced perspective with your hand in front "for scale".

Is the lower of the ferrule thingies on the side, where you plan to fit an element??

If so it looks a lot too high.
You need the element as low as possible so that it does not get dry and burn out.

Hey Geoff,

Yeah it is - looks like the fabricator didn't quite get the memo on that. I'm not too worried about it, it'll be fine for my first run as I'm not going to strip it (one and done), so the water level shouldn't dip below. I'll have to get another ferrule added and blank that one off before I do too much more

Posted: **Tue Feb 08, 2022 6:22 pm**

Don't, maybe, get the fitting WELDED over, you can get a blanking ferrule fitting if you want.
And if you want you could get say a 3,000 watt element and put in there.
That would blank off the hole, and give an element to use if the other dies. Instant turnover.
Probably even work okay without running through the controller...

Have fun.

I've got a few blanking caps here so I'll throw one of those on in the meantime and look at another element long term, appreciate your input Geoff

It’s a beauty NZPete . Love the legs and Handles

Very cool boiler build.

If you have a long nut welded to each foot, you can screw in swivel locking casters. I love being able to roll my boilers around.

Another option would be to make a platform with castors to set the boiler on top of. I put all my fermenters on wheels and it's really convenient.

Wow beautiful boiler! Very nice work. Looks professional!

Thanks Brian but it was built by a fabricator, not me - so your comments are spot on!

I picked up the finishers boiler today so I will be looking to do a cleaning run tomorrow if family life permits

Posted: **Fri Feb 11, 2022 2:36 pm**

I went to put my still together this morning. Unfortunately I think i left my 8" clamp with the fabricator so that's on the backburner til Monday now, but I assembled it as far as I could anyway.

Remaining items to do:

Wire up controller and element
Replace compression gland and fit thermo
Clean everything
Vinegar run
Sacrificial wine run
Run my sugar wash

Getting close. It seems like I'll never get there but I think I'm inching closer!!

It sure is coming together. Curious ... what is the left side of that tee for?

I've got it set up with a compression gland for the thermo, so it doesn't get splashed with falling reflux

Got it. That's what I thought. I'd ditch that elbow and put the thermo directly into the tee as long as it is short enough to not be in the falling reflux. You could try it both ways to see if there is a difference in temp, but if there is any difference in temp it would likely be within 10ths of a degree F. I don't know if there would be any difference or not. I put my thermowell between the tee and my gate valve to monitor the vapor takeoff temp. I'd be curios to know if either placement would make a difference.

Sounds like an experiment waiting to happen

Fellas!! Finally, vinegar run today. Missing the thermometer fitting still (next couple of days hopefully) but figured I could run some vinegar at least!!

Posted: **Tue Mar 01, 2022 2:31 pm**

Looks gorgeous! I look forward to hearing how it runs with that SPP. By the way, is that a 2" or 3" column. It's hard to tell scale with that FAT boiler.

Posted: **Tue Mar 01, 2022 3:27 pm**

It's official, goes good on the vinegar run! A couple of observations:

- Lots of steam out the top but hopefully this is just the vinegar
- the only leak appears to be occurring at the PTFE 8" gasket at the top. Anyone got any suggestions? I've tightened the shit out of it but there's still a wee leak in one place

SaltMustFlow - it's just a 2", bit of a baby!

Posted: **Tue Mar 01, 2022 3:49 pm**

Maybe, mark the leak spot on the top of the boiler, on the clamp and the concentric reducer. Check everything with a small straight edge in the long term. Short term a wrap of Teflon tape and rotate the tri clamp around to a different spot and see if that solves it

Posted: **Tue Mar 01, 2022 3:50 pm**

The ferrule warped during welding. I had this happen with some fittings I had TIG welded. In the end ... silicone gasket worked flawlessly. Of course some might say that only PTFE gaskets are approved. Yeah, well they do not work and cannot work in this case. Some might recommend wrapping your PTFE gasket with teflon tape to help it conform to the warp. Sure, but I'm not willing to do that over & over year after year.

I wouldn't worry about it, but I'd keep your eye on it when you do your first sacrificial run. IF you vapor is bypassing the reflux condenser, you can tease out a couple of stainless scrubbers or copper mesh to stuff within the coil to help diffuse the rising vapor and encourage it to condense. This is common. Hopefully you won't have to. It would be nice to keep a perfectly clean look, but not big deal of you have to.

Thanks mate. I swapped out the gasket to a silicone one and reran the vinegar, sure enough the leak stopped. Not sure where that leaves me but I'll marinate on it!

Now that's sorted, I've got 0 leaks and I guess I'm ready to push into my sacrificial run. Unfortunately I'll probably have to wait for the thermo compression gland for that!

Posted: **Tue Mar 01, 2022 10:13 pm**

If the warp is not too extreme you can correct it with a small sheet of glass and some sandpaper. That would be a better solution.

Great , a Silicone gasket works . Unless you wrap it in Teflon tape , we don’t want to hear about it on this Forum .

I can’t see why you would have to rewrap it time after time . Surely you don’t need to remove the 8” lid every time you pack down .

Even if you do , Teflon wrapped gaskets can be reused over and over again before needing a rewrap .

My lid is 6" and reduces to 3". My 3" column is filled with small bits of lava rock over top of some copper mesh. The lowest 3" gasket supports the packing. When I break down my still, I remove the PC, the VM head and I'm left with the vertical column on the boiler. I remove the 6" clamp (all packing retained) so I can simply pour out the lava rock. It is much easier and safer to do it this way rather than try to detach the 3" column from the 6" lid and risk losing packing all over the floor. SPP is far more expensive and not worth risking.

Teflon tape is the weakest link. It's weak, flimsy, deforms, compresses and would be the weakest link. I'd sure hate to have to worry about that gasket every time I fire up the still.

Posted: **Wed Mar 02, 2022 8:01 am**

There are PTFE Envelope gaskets. PTFE on the exterior and soft EPDM on the interior. This would be far superior to PTFE wrapping the largest gasket on your still and worrying about it every time you fire up your still. Wrapping with tape is not a good long term solution for a joint you intend to be removable.
