[@nunovyobeeswax4177]

I put a ball valve in the section between the T fittings which is great for not only sending foreshots out without disturbing the flavor stuff in the thumper, but also lets the air pressure in the pot even out when open at the end of a run before turning the heat off the pot, preventing implosion.

[@BeardedBored]

Nice!

[@TheChefmike66]

Wow, great idea!

[@StillIt]

Bahahaha love the dune reference! Awesome to see this vid live my man :)

[@BeardedBored]

Hahaha, thanks fellow nerd!

[@ronfussell8244]

Mr Bearded,my thumper is just like that,except for a little change I made,your verticals may be too close together,but remove your 90's and replace with T's,put a valve between them,now you can run like a pot,close and activate thumper,or open on shut down for open system,it works!

[@mines2sekel315]

Put a on and off valve on your thumper. Where the elbows are at. So you can keep running. Open for the four shots and heads. Then close it to push the steam down into the thumper for the flavor.

[@near--zero]

the clips are also called draw-latches, you can get them from mcmaster-carr, grainger etc.

[@narcsurvivor6969]

I'm late to the party but thank you bearded. I've learned more in watching this video that I have in dozens of others. One thing I've learned is to keep your thumper above your boiler. This will keep your thumper from filling up. Also as another option, disconnecting your thumper from your boiler right as you shut down will help clear the vacuum. Good stuff brother I appreciate it

[@austinwhitaker6439]

Hey Bearded, Man you did a great job on your Thumper! I'm old School and a 5th Generation "Hobby Distilling Moonshiner ;-) " and i just have to have a Thumper. You'll be pleasantly surprised at how much your proof goes up especially when you get to know your Thumper. Man I'm so happy you're going to be using a Thumper! Theirs just not enough people using one and teaching and educating our community about them. I'm really enjoying the direction of your channel. Thanks For sharing Man!! Looking forward to the follow ups. Your on a Roll 😁

[@BeardedBored]

Thanks Austin! I'm really looking forward to it too:-)

[@rocketsroc]

I wouldn't get too excited about a thumper, they really aren't worth the effort.

[@austinwhitaker6439]

@@rocketsroc the great thing about this "Hobby" you can do whatever floats your boat on whiskey River, if you are running say 4-300 gallon Pot stills your obviously shooting for higher Proof so a Thumper or thumpers are Wonderful but if you are playing around with a 3-5 gallon Still then a Thumper probably isn't worth your effort I agree....

[@clintonhoush1088]

Been enjoying the hobby for about 6 months now. I see people's love & hate on thumpers. I enjoy having the option there to infuse other flavors or even doing a flavored water run too. On the "hypothetical" side, being able to take a known good run, adding an extra flavor profile into the thumper, and getting a slightly different product out is fun. I love to experiment on cooking & baking anyway, so for a "tinkerer" type of person, that thumper allows a quick & easy minor change. Going to be learning how to braze soon to give this build a try and make a slightly bigger condenser (Vevor 8 gallon still) as well. Glad when I saw this channel on Still It, very informative and kind of a tinkerer type of person too.

[@samuelrspade]

Other than size restrictions and cost what about a pressure canning pot. Replaceable lid seals and no latches to install. Pressure relief valve built in. They typically have a pressure gauge installed, you could use that opening as a port for piping. Excellent description of the thumper and build! Thanks!

[@BeardedBored]

Should work fine.

Glad you said that.( he says as he runs to take the mason jar off his 5 gal.)

[@southcack8245]

Interesting factoid - the thumping sound comes from the instant collapse of the hot vapor as it hits the cold liquid in the thumper. It will quieten down considerably as the thumper liquid heats up.

[@rjfussell]

I'm like a Jedi on the mechanics of the process,when you brought up the process of shooting the thumper,I thought back where I seen this ,then it came to me,it was a wide pony keg with a 4 inch ferrell on top,after the heads,he just popped the clamp,opened it an put a bunch of fruit in it,he did lose heat,a little steamy,so I thought about the bypass,which is only a valve above the top,you run the heads like a standard pot,when your through heads you open the 3/4 ball valves and let it go,then to avoid any chance of vacuum you close the valves at the end and your back into pot still mode and simply shut down,my mistake third valve in the cross over,your thump is charged from the start,works fine,you've taught me a lot,all three of you have unique perspective.

[@ericfortier4036]

[@douglascolman4501]

Thanks for the info. I like your attitude and way of getting the point across. Don't do this or that because you will have problems. I'm gathering your information before I start to build my first effort.

[@BeardedBored]

Thanks brother. Good luck on your build!

[@robradcliff6415]

For the folks using kegs for your boiler, half kegs make excellent thumpers too, and they like the big kegs seem to heat very evenly and fairly quick too. My latest, im actually going to pick up the small keg now, but im going to drill a hole close to the bottom and weld in a fitting. Remember on these the bottom isn't flat, so not as much worry if your pipe goes all the way and touches. I even cap my pipe and drill 20-30 tiny holes for about the last 2 inches, and even in the cap. So my thumper generally don't thump, they make a sizzling sound, guess you'd call them sizzlers instead? Maybe? Who cares. Be safe everyone don't die making shine, save that for way later.

[@BeardedBored]

Thanks for the advice. I'll upgrade to that one of these days;-)

[@BeardedBored]

I knew there were other nerds who would appreciate it as much as I do;-)

[@brucekrisko4364]

Try placing a pipe cap onto your dip tube in the thumper and drilling several small holes in it to disperse the vapor. 5-5-1 is a great cleaner for copper piping and to remove solder flux! No need for a sacrificial fun.

[@BeardedBored]

Thanks for the info

[@olbenparker310]

Another GREAT Video!!! Excellent safety explanation!!! I built my thumper with a tee and two ball valves for a by-pass line around the thumper. When starting up my still I open the valve that by-passes the thumper (while the valve to the thumper is closed) but goes through the condenser. I have a cork stopper in a tee between the by-pass ball valve with a thermometer to give me an idea of where the temperature of the vapor stream is to also tell me when the foreshots are boiled off (and I also collect the foreshots at the end of the condenser they are a very good solvent for cleaning). After the foreshots are gone, I open the valve to the thumper and close the valve to the by-pass in that order and let the thumper come up to operating temperature. I also add a 50/50 mix of tails and boiling water to my thumper to get things heated up as much as possible. When I shut down the still, I wait until the condenser stops dripping and then open the by-pass valve before walking away. I have seen the video of people throwing water into a 55 gallon drum on a fire and closing the bung hole and spraying the drum with water. the effect is drastic!!! Actually that is how the thumper gets its name. As the hot vapor starts to hit the slightly cooler liquid in the bottom of the thumper the vapor condenses and sucks a small volume of liquid from the thumper into the down pipe (that is why you want a short section of pipe above the thumper). That small amount of liquid moving up the inlet pipe makes a thumping sound.

[@garthhorne617]

You save me soo much time trying to figure out the details and attempt a build. Great sage and well researched advice. I was going to build a thumper but after watching this I think as you suggest better to perfect and learn the nuances of my new build first before adding this module to my system. Thanks again for another great video.

[@BeardedBored]

Happy to help:-)

[@mikeinnj4424]

Yes, great advice for sure. You don’t know what you don’t know, meaning learn the basics about your still and you will figure out what you need to change or improve upon. Lots of ways to spend your money. Don’t rush the process and enjoy the journey.

[@Colsos]

I’m so happy I found this video…I was going to try it with a glass jar like seen in other videos. I have bought a cheap still vevor 50l without the thumper…happy now I made that choice so I can build my own in the future. When I feel a bit more seasoned. I made an instant sub on your channel. Thank you sir!

[@BallisticJell0]

Dammit Bearded! I saw the title and said to myself I'll make a Dune reference comment! And you beat me to it! Your taste in booze and sci-fi (a Dune fan and an SG-1 fan) are beyond reproach!

[@BeardedBored]

We must be from the same nerd stock:-)

[@adamzamora983]

Another great video! Something I recently learned about thumpers: If you insulate them, the tendency for them to fill up over a run will decrease a bit, which will help if your thumper is on the smaller side compared to your boiler.

[@BeardedBored]

That's a great point! I'll mention that in the next thumper video. Thanks brother!

[@chrisbartholomew3643]

How do you insulate them?

[@adamzamora983]

I got a small piece of insulation from Home Depot and wrapped the thumper with a bungee around it.

[@mikejoyce6598]

Word of warning: Be SUPER careful dremel-ing out copper pipe. About a year ago I wrecked about 25 square feet in my basement because I took a dremel to a copper pipe using a burr-style bit. The copper dust wasn't actually dust but millions of tiny shards that instantly dig themselves into your skin/clothing. It was weeks before all the slivers came out and no matter how hard I scrubbed that concrete floor there were still hundreds of shards there. Either use a sanding bit (which just creates dust) or do it outside. Also, the shards really stuck to the inside of the copper pipe and it took some ingenuity to get them out of there.

Gotta say, I'm going to be checking back on this one, just to read the comments. I have to admit, what I run now would be considered a column still and I have no real desire to complicate what has become a reliable process. But super interesting.

[@BeardedBored]

Do what works for you and makes what you want;-)

[@davidduncan6280]

I have the same pot as my thumper. I have always used it. I have a 10 gallon boiler. I do use silicone as a seal and wrap it with Teflon tape. I have never found any foul flavors from it. I also use regular wood clamps( med. Size) to clamp it down. I have never gotten a leak that I could not fix with another clamp. I did add, on both my pot and my Thumper, a ball valve. Once my run is done I open them instead of undoing all the clamps right away . I just open the ball valves. Instantly releases the pressure as it cools. Wish i could leave a picture. All in all nice video.

[@BeardedBored]

Woodworking clamps are the best! I almost went that route, but figured I'd see if I could work out the spring clips. I like that ball valve idea!

[@davidduncan6280]

Yes they work great. The only draw back is storage. I did order the same spring clamps but have never used them. I got them from Wish.com. I was watching your condenser build I also went that rought. However i made it go through two. The first is right off the thumper about a foot long. Then a 90degree turn to my 4 foot one. Works better then a worm and wont clog up. I like the wire wrap inside the water jacket. I may have to take mine apart. Thanks for the response back. Happy distilling!!

[@BeardedBored]

@David Duncan 👍 👍

[@SyBernot]

You could have utilized your support for an inline poppet valve to break any vacuum from the condenser side to the linearm side, the bung in the top is always a good idea to prevent overpressure.

[@BeardedBored]

All videos of use of expanded ptfe tape show you just overlap the tape. Due to the foamy squishy nature of tape it should create a continuous seal under compression without leaks. But if you wanted to be neat. Overlap it. Then with sharp craft knife cut through both layers at joint on 45degree angle. Job done. kzbin.info/www/bejne/ZnSskpeMhbSid6M

Great info....long story short, my cousin won master distiller on moonshiners a few years ago (don't wanna mention any names 😎). We have a brandy still and a big copper still that has 1/2 gallon mason jar thumpers. We've used this setup for years without any issues whatsoever. He runs 2-3 times a week year round and hasn't broken a single jar, surprisingly. I honestly wouldn't worry too much about the glass not holding up, there's hundreds if not thousands of runs on these jars and we've not had any issues. I would've never believed it if I hadn't used them myself.

[@southcack8245]

Safety suggestions: cut a couple of notches in the bottom end of the input tube, open up your boiler fill port when you shutdown to eliminate any boiler vacuum, don't run on the grain without a PRV. Use common sense and read some of the thumper build threads on the forums. George's video about the crushed boiler was meant to discourage the use of a thumper. Mainly because PIDs don't work with thumpers, even though he doesn't say that in the video. Better to just rag on thumpers I guess.

[@BeardedBored]

Yeah, he's not a fan of them. But there are just too many cool things about them to not have one. Hopefully I can show that in some upcoming videos:-)

[@Tonnsfabrication]

To make the gasket use 100% food safe silicone and apply to the lip on the lid . Most lids have a lip to hold them in place which creates a valley to which you can fill with silicone and use a flat spreader to lat it down flat and level. I'm not a fan of permanent placed lid clamps , try a bar joist beam clamp, they can be altered to fit and work quite well, looks like a mini c clamp. I've had many variations of pots over the last 15 years and the silicone on the lid has lasted that long and still working.

[@BeardedBored]

I was going to go with food grade silicone. But before I bought it I decided to check the chemical resistance because I'd read a few things that made me wonder. Here's the website I used to check the resistance of various gasket materials to various compounds in a run - www.coleparmer.com/Chemical-Resistance

[@Tonnsfabrication]

@@BeardedBored Did ya also know that PTFE will off gas chemicals lethal to humans in small doses if used in high heat situations? You're not reaching those temps but why would ya use it knowing that? Especially making ethanol that you plan to drink. The basis of silicone is silica sand, carbon hydrogen and oxygen, two elements that are are already in your mash starting out.

[@BeardedBored]

That's true, but as you said the temperature range of PTFE is quite high. 500F is the upper limit for _sustained_ operation, and doesn't start burning until around 620F. Your pot still would have to be on fire to get that hot. Below that temperature there is no off-gassing, which classifies ptfe as thermally and chemically inert under normal operating temps. That stability against thermal and chemical breakdown is why PTFE/Teflon is an industry standard gasket material for commercial distilling and other industries, as well as being the most common non-stick coating for cookware. I'm not saying standard triclamp silicone gaskets are bad for you, but they do react to acetone. I have to assume the same is true for food grade silicone. It is a much easier material to work with and would have made my project a ton easier, but I chose to go with PTFE for the added bonus of its non-reactivity.

One thing I have learned in industrial safety classes.. think of the dumbest thing you could do. Now figure that at least one person who could use what you design may have the ability to do something at least 25% dumber! It may sound impossible that you would forget to open a closed ball valve, but... if you did..bad times had by all! The liquor fairy here keeps a coupler uncoupled until time to run to the thumper.

Try cutting the gasket ends with a razor blade and use super glue. As the thumper fills the back pressure will slow the flow out of the pot kinda like stuffing a column, 5 pounds is a lot. The thermometer in the pot keeps the water out of the shine ,I say yes, use one. You know the rubber plug on a pressure cooker lid? Thanks.

Pro tip.....but just the tip. When you're marking holes to mount anything, put it on your printer and make a copy of the hole pattern. It'll work for anything... clips, surge protectors...... Anything that'll for on the printer glass.

Mason jars are more often used like gin baskets, to infuse flavors which you can do with a thumper too no problem. They can also comfortably withstand temperatures up to about 280°F which with a still, you shouldn't ever really get above 180°F, which is well withing the working range. They can withstand a vacuum pressure of well over 15 psi which means it can withstand a postive pressure of equal grade. For small stills theyre fine to use cause you really shouldn't develop any more than about 1-5 psi max depending on your setup. If youre getting higher than that theres another problem somewhere else.

[@DamacusSquared]

So unless you're being an absolute moron, they should be perfectly fine to use so long as youre using canning mason jars, which are made for taking repeated heat and pressure cycles. Both mason jars and sight glasses can be made from either Borosilicate or Soda-lime glass.

[@DamacusSquared]

Add some spring clips hooks to the lid for an extra level of safety, I know there's a a lip around the top, but having that extra level of security can keep you thumper from blowing it's head off.

[@McElb]

Instead of mason jars order glass globes for paint shop lighting. The threaded end will fit a mason jar lid and the bottom end is rounded instead of flat, really adds to the cool look. The glass is heat tolerant as sight glass would be. It takes the danger of rapid tempiture change breakage out of this type of thumper. If you want to really go cool take a 2"x1"x2" copper tee and split the copper on the bottom side then flaten the 2" long side into a flat peice of copper with a 1" fitting coming out of it. Cut it to size of jar mouth. Take a 1/2"×1/2"×1" tee and grind out the stop on the top 1/2" fitting port so to slip a 1/2" pipe threw it to the bottom of jar then you can come out the side of the tee with 1/2 pipe to worm. Ptft tape makes good gasket for the flat mouth lid peice. A lot better than soldering two pipes threw a flat peice of copper. Solder is prone to run out of on joint while soldering the second one. The 1/2" pipe going threw the 1" fitting leaves room for vapor exit back up and out the side 1/2 pipe. If you run a hot pot maybe use 1 1/2" instead of 1". Safer to have more exit room incase of puke causing preasure.

As far as I know he's still ok:-)

Great advice!

[@MrBigmandesign]

Cracking video, you made a cracking point regards to fore shots/heads going through the thumper, shutting off & then adding backings to the thumper, I started my build but have added a bypass using ball valves to save having to shut down, can you see a problem with this at all? Just thinking of pressure but as long as I open the one in & out to the thumper before closing the other, I think I should be ok.....right!🤣

[@BeardedBored]

Yeah, should be fine. There are lost of interesting bypasses that guys have built into their rigs on the forums. Next time I tinker with mine I'll add one in.

[@moeshiner156]

Good Sunday morning B and B. I have reversed engineered a stainless steel pot design for a still using info from you videos and need to purchase the copper pipe. My still pot will be 10 gallons and my Thumper will be approx 3 to 5 gallons and then to maybe a 10 gallon pot for the worm for cooling. What size pipe should i have from the still pot to the thumper and from the thumper to the worm and finally the size pipe for the worm itself? Your help in this last step will be all i need for completion of this beautiful piece of equipment. Many thanks!

[@BeardedBored]

1/2 inch copper works great from an elbow at the end of the column all the way to the output end. Most still are 1/2inch after the column. Good luck on your build.

[@jamesramey3549]

Great bits of info, I appreciate that you do alot of research. Does anybody ever put a thermometer at the exit near the condenser, or anywhere for that matter?

[@BeardedBored]

I've seen some folks do thermometers in the outlet of the thumper, but I have no idea if it's accurate enough for cuts. Maybe one of these days I'll see if I can rig one up with the PID George gave me and find out what happens;-)

Have you thought of using sharkbite fittings to assemble your parts?? It's a simple push in system and easy to assemble and taking it apart.

[@tracylee2209]

A pressure relief valve will not relieve a vacuum that has formed in the thumper/still. The ring on top will allow you to manually release the vacuum, but would not be a safeguard if you were forming a vacuum unless you could keep the ring up somehow when you turned the still off because it has a spring inside to keep it closed

[@davek5777]

Bearded and Bored - I have just finished making a similar thumper set-up for a buddy of mine. You mentioned a pressure release valve at 5psi. The ones I got were 20 psi - I'm assuming that it won't necessarily make a lot of difference - but if you think they should be 5psi, i can change them out. I also added stainless pressure gauges (25 psi) and stainless thermometers so he can monitor/regulate the conditions within the system via heat control. The set up is very similar to what you mention in this video. But one question I did have, after watching your video - is that you mention of brass not being a "good" candidate for any copper-copper + sweat connections. In the my setup, I sweated in stainless valves (in brass housings) so the thumpers could be segregated or run in parallel - I'm hoping that this won't be a deal breaker for the setup. Thanks for your cool demeanor and very informative videos. They are appreciated (by many). I will upload pictures asap

[@BeardedBored]

I'd swap out the release valves to no more than 5psi because it prevents any sort of a problem, long before you get into dangerous territory. 20psi is higher than a pressure cooker, and those things go boom when they fail. The issue with brass is the potential for lead in the brass alloy. In the commercial brewing and distilling industry they don't even use lead-free brass. If you used lead-free brass, then it's your call if you want to swap it out or not. Some folks are fine with it, some folks are dead set against it. Up to you on those, but I definitely would swap out the release valves. Sounds like a cool build. Email me some pics;-)

Mason jars are actually made to withstand very high temperatures. That’s why you pressure cook with them. Still probably not worth the risk, but still tho.
