Home Distiller

Hi guys. Boyfriend and I are in the process of building a 2 gallon ss thumper to complement 5 gallon ss pot still we already have. BF aquired the 5 gallon with the lid pre-fitted with port to accept tubing. My question is what is the actual name of the connectors shown in my pics? And also, is there rust accumulating at edge because there is another metal being used in there, like brass? I think I read on here somewhere that you need to "pickle" brass then work with it quickly before oxidation sets in? Is that what's happening to the underside piece?

Top of lid: Underside of lid:

The copper is a male adapter. The other to pieces are steel made for electrical connection and not suitable for a still. Do not use them.

Yes those rusty nuts gotta go. They are lock nuts for electrical conduit fittings. You'll need to re-work your port with something that's all copper or stainless.

Thank you for the heads up. What is the official name for that part, the locking nut? Are there 2 pieces to it, one for each side of lid, sorta acting like a collar? Is there threading or "teeth" to grip better onto the lid?

It's just called a conduit lock nut. You have two of them there, one on the outside and one on the inside. The corners on the lugs are angled so that they bite into the metal and resist backing off.

Read acfixers post again, then study this.http://streamlineproductinfo.muellerstr ... ackedasset

Yes they are electrical conduit lock nuts. Remove those, clean the rust off the lid, and solder the copper to the lid with Harris Stay-clean liquid flux and Harris Stay-brite8 solder

The nature of your question makes me think you should put together a napkin diagram of what it is you intend to do.
This way the gang can keep you pointed in the right direction.

Here's a stainless steel locknut

Here's the best I could come up with. The lid in original pic belongs to 5 gallon mash pot. Looking into Harris Stay Brite.

Thanks, looking into these.

Ok sure.
Are you up to speed on the piping inside your thumper then?

I would (btw) highly recommend that you make your flake stand / worm at least as large as your primary kettle.

Those little tiny worm buckets you see on the internet simply have minimal knock down power for the duration of the run. You'll be an ice jockey in no time.

Certainly you can plumb in a fresh water replacement system.

Yes I think so. Thumper will have long 1/2 in copper tube going to bottom. BF cut end of piece in half about 1/2 inch up then cut off one half to direct steam towards center of charge. Then exit port that will connect to our current condenser.

Current condenser is a 5 gallon plastic Homer bucket with 1/2 in copper coil worm. We went with a 2 gallon thumper to stay at 40% of mash pot.

Yes Miss Jane.
That is what needs done.
A clear view can be seen if you click on my 3D drawing.
Though I did not show the cut end as your beau intends to do.
It's not a bad idea at all btw.

It’s a “Bulk-head fitting” yes they come in brass and copper all types of material but they are used when hydralauic lines have to pass through a compartment wall it secures the point of entry also used on brake systems, air systems things like that!
