- In this video I describe my attempt at making a home made vibratory tumbler for deburring and polishing parts. After about $50 in materials and several days of my time I concluded that it was an utter waste of time. I have another video showing the Eastwood tumbler that I bought shortly after making this vid, • Tumbler Part 2 - Eastw...

Bravo! You can't even imagine how nice it is to hear someone admit their DIY project failed! Mine usually fail 2 or 3 times before I can work the bugs out, I I'm pretty sure it happens to everyone, just very few can admit it publicly! Thank you! For your honesty and sharing your idea's!
I give you props on your attempt, and express sorrow in your defeat. Thank you for sharing your experience with us even though the outcome wasn’t what we all hoped for.
Love that double bucket design. Thanks for that tip!
Thumbs up just for making the tumbler sound at the beginning.
Made us laugh.
Thanks for sharing your experience with us. I was thinking of making one like the one you made but I am now going to look at a commercial one.
@ArtistBlade1972 Great info! Thank you for sharing and teaching me something new, I didn't know that poles in the motor dictated RPM but it makes sense. I knew about VFD's but they're waaaaay to expensive for this rinky project. However I do want to get at VFD for my lathe!
I've been looking at those 18# Eastwood vibratory tumblers. You saved me some time, and frustration in trying to build my own. I use Eastwood compounds on my bench buffer. They do what they do well. I'm making a gazillion identical wooden parts, and am thinking about tumbling them to sand them and round the edges, dry media, of course. Know of anyone who has done that, you by chance?
May someone mentioned it already, but the motor bearings will not last with the "vibrator" weight on the axel. That is probably why the motor overheat. Maybe better to mount the weight separate on a axel on the base, and drive it with a fan belt from the motor. That will isolate the motor from the worst vibration. I'm no expert, but it just seems to make sense to me.
You are right. It was unkind of me to comment negatively on your video. You were just putting it out there to help people, and I spoke negatively. It is out of my character, and I am sorry for that. BTW, I made one very similiar to yours and it works great. Thank you.
+LakesideWeldingJerry No worries, thanks for being man enough to come back and say that. I'm glad to hear yours worked well!
Ups l,g.
I totally did not expect your conclusion! I was thinking to myself "bucket will crack", "bearings in motor will wear out" (from being out of balance), etc. good of you to man up and say better to buy one. Excellent vid man. Props to you for trying it! By the way, I thought your design was pretty damned good!
I very much enjoy your videos!
I like your honesty about the set up...even you made it...lol
John in the past.. There's some Awesome success in your future! Keep it up!
thanks for the work ...
Great testing, John. Saved me some time. Thanks! :)
@ArtistBlade1972 Good to know. Right now it's a 110v single phase 1HP motor, a bit more HP would be nice as well as VFD control (in my dream world haha). I don't have 3phase in my shop, stuck with two lousy 15a circuits which is barely enough if I'm careful. Gotta do some serious re-wiring and get 220v out there.
@JohnGrimsmo Anytime brother. VFD's are designed to operate 3 phase motors, but they will drive a single phase motor using 2 outputs. Not sure what your lathe has but if it is single phase it's best to put a dummy reactive load on the unused output.
Could've drilled the mounting hole for counter weight on motor 1/16" to 1/8" inch offset. The curved bottoms in commercial tumblers help a lot so a large bowl would work better then a bucket and so would a smaller funnel. My q for you is where did you get your mini mill.
Jhon this tumbler may also work for gun brass. Thks. And pretty good work. Congrats from argentina.
Hi. I think you did a great job even though you weren't happy with the end result you know so much more now than you did before starting. I need to thank you anyway because I have all the parts I need to make a similar unit BUT! I'll go and buy a small one for my coins. So even though you felt it was a waste of time I believe you helped out a lot of people around the planet. Thanks so much for your honest appraisal. You could have fudged it and you didn't. Well done! Chris. Perth Western Australia.
Thanks Chris! This was over 2 years ago, and now I just ordered a $800 on a much nicer much bigger tumbler that should be wicked awesome. Sometimes it's just worth spending money where it counts ;-).
Haha! I love the twist in the end of the video! I actually thought you would manage to make it work, but then "this is just crap, don't waste your time".. That's really what you call usefull info. Thank you! =)
Awesome project mate.
Hey, great video. I like the fact that it didn't work and you still uploaded it. I think we learn more from our failures than our successes. Anyway, just a thought. You might try moving the counterbalance off of the motor shaft. My guess is that you are getting heat build up from the friction created by lateral pressure on the shaft bearing. If you use a belt drive and move the counterbalance to the platform you might significantly cut down on the heat generated. Anyway, nice vid.
John, an AC induction motor's speed is set by the line frequency and the number of poles in the motor. For every 2 poles added the speed is divided by 2. 2 poles=3450rpm 4 poles=1725rpm etc. To control the speed you must control the line frequency. You can buy a commercial variable frequency drive, or make you own should the need arise. Dimmer switches work fine on universal motors running on AC (motors with brushes).
Ten minutes of my life I'll never get back
That's a pretty great idea actually! That will take all the wiggle wobble force off the motor shaft and into the bearing and frame that you'd have to build. Sweet. However, I got a good tumbler now so I don't need to worry about this kind of stuff anymore haha.
Ive never tumbled my own stones before but I have inherited a bunch of semi-precious stones like Lapis and malichite and other stuff like Nuummite and also some gems like rubys etc. Some are already polished but alot of the larger malichite peices(which are rather large, like a bit smaller than an average boweling ball) and I dont know if a tumbler is gonna work for such large peices? sould I just buy a tumbler or can tumbler handle large heavey peices of malichite and Nuummite?any suggestions?
Hola John tu maquina sirve para pulir piedras?
Thanks for the upload
just finished my vibratory tumbler, was simple, used a large coffee can for testing purposes, a sewing machine motor and brazed a nut to the side of the small pulley thats on the motor and put a threaded rod into the nut with a bunch of washers and topped it off with another nut, then flipped the mount around and mounted it to bottom of can with the funnel inside. then can just take a small box with weight in the bottom and fold the top and will lock the motor down..
@themediocrepirate Not with this tumbler, the overheating motor prevented me from running it long enough to properly test any kind of media. I like the concept of this design, but it would just take so much dicking around to get it to work well. I'm happy with my eastwood one, new vid posted!
Nice setup. Looks a little slow though.
I made one using a car polisher and some plastic containers. I removed the polisher motor which already had a offset weight attached to the shaft. Cleans rifle cartridge brass in less than 1 hour.
Good video may use your ideas to build large one .
I use the Harbor Freight 18 # vibratory polisher already , I would suggest buying the 2 year extended warrenty though and wait for coupon or sale . It cost around $150 and I will have an issue with it and return it just before the warrenty is up for extended life . I have used mine about a hundred times with full loads and it does what is supposed to do and is probably made the same place in China as the more expensive Eastwood polisher .
Nice video. Thanks for sharing.
Though one point.....Yes you can put a dimmer switch on an A/C motor PROVIDING that the motor is a variable - speed - motor.
Any reason for the corn instead of maybe like aquarium rocks?
"NOTHING VENTURED, NOTHING GAINED"!, as said by Ben Franklin and not your typical COUCH POTATO. I respect and admire anyone who sets out to use their brain to create an idea of their own, with or without fail, because rarely does one engineer the idea perfectly on the first try. Its all about changing and modifying to make it a better successful creation. (with exception to wacko's making homemade bombs to injure innocent people) Here is another quote that I like, "CAN'T, NEVER COULD", otherwise, CAN'T NEVER WILL BECAUSE THEY NEVER TRY ANYTHING OUTSIDE THEIR COMFORT ZONE.
You said "there's to much weight *it works great* but ya there's too much weight". If it works like you want it to, figure out how to keep the base of the machine from moving maybe add some weight to the base but just remember there's no such thing as problems only solutions and obviously you do know that because if you didn't you would just bought a tumbler or totally negated the step but no you came up with a solution just remember to apply that to everything you do great video man keep up the good work
At least you're honest! Ha ha loved it.
Check the motor temp rating. Some motors are rated to safely operate at a temperature much higher than room temperature.
Sorry that was a question. It will work???
Can I use rewritable CDs is it?
"If you don't know what it is, Google it.' So matter of fact. Epic.
Trust me. you are going to love having a tumbler in your machine shop. i have used many many different formulas for polishing cleaning deburring ect. some examples are even ajax cleaner and water, white sand, dawn dish washing liquid. have fun with it. from Bob
it goes ahyuuuyuyuyu. ill keep that in mind building mine.
Have you ever tried "Kitty Litter" apparently another person has used it and his part came out not only clean of rust but shiny too :)
I watched John. Lol. Love that fan blade bro. 👍 btw I think that craigslist motor was the trolling motor on Noah's Ark bro. Hahaha. No joke !!!! Lol. Just kidding, did u get my message I texted u today John ?
Mark McClain.
How does it go?
You can polish with this too, just use progressively finer grits.
well I staarted with hopeful anticipation, and was crushed when I saw it start running.
Am toying with making myself a tumbler out of an old washing mashine I should be taking to the dump. Thanks for the ride.
Not a waste of time if you learned something. I know I learned something. Thanks for taking the time.
how does it go when it cleans?
0:15
What kind of sand is that ?
7.57 ..... use a locknut or locktite clue for threaded nuts
How much for some manix handles??
Sorry tell me again how is it go??
good but your vibration is set wrong mate or it's you tub shape ,i have built one .it should really roll the medium around cylindrical as well as around the bucket it's faster ,mine can run continually . good job tho .
Do not use a dimmer switch on an AC motor. A dimmer switch chops the AC waveform (hence it is called a AC chopping circuit) and the lower you go, the more heat the windings take on. I've watched several ceiling fans go up in flames because of this very reason.
No I don't know anyone who has tumbled wood, but I'm sure it'll work great when you use the right media for it. The plastic pyramids should work, depending.
if you take two bungee cords and tap two holes across from each other and two holes in the board it would work better... you need that top bucket to be more secure! better yet would be to put that shaft on the bottom bucket and then tighten the top bucket to the shaft through the funnel
I've got no idea, all I know is that lots of people who use rotating tumblers use them for rocks and stuff, while vibrating tumblers are used for all kinds of industrial finishing uses.
Bought it from Grizzly then did the conversion myself. I sold it a while ago and upgraded to a Tormach.
Sorry it didn't work out bud but respect for attempting. The one thing that differ bt you and the commercial one is they had lots of time and resources to figure it out. It's ok. I can see that it doesn't rotate the media as well the commercial ones. Don't know if you still have this but I would loosen the mount springs, add more weight to the spindle or use smaller sized media?
Love DIY, and kudos for a great build, but a heap one on eBay is about $50 and you can add water/solution without it leaking...
Really appreciate the honesty dood. I was with you all the way! Fair play
I doubt the the bearings in the furnace motor would last long in an out of balance condition. You would be far better off to lay the container on it's side and build a rotary tumbler.
well you know when you off set it with wait, that can make one over heat, it would be because when you added wait to the shaft, you make the barrings off as well. or something like that, but was a good idea though
I think a good idea would be to use a conveyor belt to power the excentric wheel, thus you will save some life of your motor's bearings and you will be able to achieve higher speeds through different diameter wheels gear.
*off balance. was the word you were looking for.
Great video.
You say you have $40 into this, you could have bought a commercially made Franklin Armory one for the same price at Midway USA!! Hope you enjoyed your project. Good luck.
rubber feets?
dont worry about the bolts flying they can hold a ton of force
Nothing rusty lying around?
I think that it didn't work well because the axis of the motor should have been vertical. Otherwise it is a nice design using the buckets which can be easily replaced.
Not sure if you ever found the fix for your nut worry of coming off. Just get a clinch nut, not a nylock a clinch nut then it will not come off. You were on the right path but a sander would work better because of higher rpm vibrations.
One Idea is, you could offset the hole of the aluminim that fits on the shaft
0:15 Best part of the video :-)
Welcome to induction loads over resistant.
Why didn't you just use a bunt cake pan?
I would recomend using either duct tape or electrical tape to hold the nuts on and to keep the buckets tight.
A tumbler instead of a vibrator set-up would have been far easier and productive for your needs. And, you would have saved the $200 plus dollars spent at Harbor Freight. Don't get me wrong. This is NOT a BS troll comment....just a bit of a suggestion because I, too, am a tinker and love to come up with homemade "tools" for various needs. The only problem to work on would have been deciding on the container to use. Your motor would have provided plenty of power to turn a container with a screw on lid, sitting on rollers made from wood ( cut outs made with a large hole saw ) or some salvaged wheels from a pair of roller blades or an old skateboard or 4 lawnmower wheels. Transfer the motor's turning force by using a couple of pulleys and a V-belt. Anyway, good thinking on using old auto motor valve springs for the dampening structure. Tumbler set ups are used by hobbyists for polishing stones for jewelry and for crushing rock with gold content for recovering raw gold. The rock crushing is accomplished by putting steel ball bearings in the unit to knock the crap out of the pieces of rock. The steel balls are usually about 2 or 3 inches in diameter for the smaller tumblers and larger ones for the bigger units. Do a search on TH-cam for "ball mills". For your needs, a plastic, 2 gallon mayonnaise or mustard jar, with a screw-on lid, would be ideal. Those containers can be found at wholesale food outlets. Have a big BBQ to use up the 2 gallons of mayo or mustard. LOLOL. For the tumbling media, try uncooked rice. That should clean up your aluminum pieces quite nicely without causing damage. And, in addition, I do not believe tumbling OR vibrating units will smooth away the chatter marks on your metal items. That would take some judicious uses of files and/or fine sanding on a belt sander. Good luck. Use that $200 at Harbor Freight to buy a belt sander.
use wire to tie the butcket handles together...no more spinning bucket. Thatle be a set of handles for the help :D
I guess you could build a really large one for rusty wheels.
Unfortunately I don't make them any more.
JohnGrimsmo threadlocker could always be used on the last nut. If it was needed to be removed, just heat the nut with a blow torch. Great idea 😊
Why not just use red Loctite on all the threads and bolts? That should keep any of them from vibrating loose.
i wouldn't put that off center weight straight onto the motor. you'll run bearings.
@JohnGrimsmo
I hate to tell you this but if you paid $10.00 for your motor in your tumbler, you paid $20.00 too much.YOU can find clothes washers and dryers on Craigs list for free and once you remove the motors, you can easily sell the steel scrap for another $10.00-$20.00. Keep that in mind for your next project that needs a motor.
le systeme est bon sauf que le bois absorbe pas mal les vibrations un peu aussi le plastique sinon le syst(eme est bon
Had you mounted the motor to spin on the vertical axis rather than the horizontal, it would have worked better... Look at your Eastwood tumbler.
The media moving very slow
Thanks for sharing your failure.... I just made a tumbler by converting some button pushes on my computer and spending $39 for a Frankford Arsenal Tumbler, including shipping.... You can get a China made "SmartReLoader SR737 tumbler nano" for $20..... However they are small for small parts and ammo reloading and brass polishing.
the motor needs to be vertical and centered under the container.
Just tie the handles together, that will stop the bucket from moving.
That's a shame mate. Thanks for sharing.
Your home made tumbler was a good idea and would have worked if you had used lighter springs.
Well that was disappointing. Did you try different kinds of media?
I recken my tumbler will be better than yours, if I ever finish it.......... BUT! I know your other bits you make (like the Aly you were trying to polish) are better than mine. It got my attention because I am trying to make a Aly knife handle. Wish I had the mechanise you have :) Thanks for making the vid :)
Why not Just install a Metal Disc on your AC Motor and cut one side to make it un-even that way no parts to fly off lol and melt some glue stick on the lid of the first bucket. it has more friction to help with the moving around of the 2nd bucket
Sorry this didn't work for you. That motor seems like overkill to me. I've had good results with a $5 craigslist palm sander as the vibrator and some old fish tank gravel as the tumbling medium. Gravel might be a bit aggressive, but it works fast and doesn't seem to be breaking down too quickly.
While it's great that you admit it didn't work, it is not so useful after taking the time to watch it and take notes
weld the nuts and bolts to the shaft...
