I'd use a plastic bottle instead of a jar. PET/PETE is pretty chemical-resistant.

Oil in the ultrasonic would be a way to make sure the oil gets in to every nook and cranny. I always imagine getting all the oil out, and not being able to get oil back in, and having pins that are completely dry. Yes, I have an active imagination.

Ultrasonics do make good gun cleaners :mrgreen:

Best excuse to justify buying an ultrasonic cleaner:

"Honey, this thing cleans chains and jewelery"

That's when she ran out to buy one (albeit small)....

-S

P.S. Still looking around for a reasonably priced AR-10/SR-25/Mk11 AR (i.e. 7.62x51/308 win) before Feinstein's banhammer falls. Any ideas or suggestions?

Same procedure as I wrote earlier.
It takes away just about anything, counting out old debt.

I've used this tank twice now and it really does a fine job.

I give the chain the old spray and brush with WD-40 followed by a wipe down to get as much of the dirt off as I can before it goes in the tank. What's cool is that the chain looks good after doing so but as soon as the ultrasonics kick in all the crap that you couldn't see starts floating out of the chain and into the solution. After a 20 min cycle you can't even see the chain at the bottom of the tank it's so murky.A bake in the oven to dry and a soak in bar oil and I'm ready to go again.

One thing about bar oil, this stuff is super tacky and attracts a lot of dirt. I give the chain a thorough wipe down but notice a lot of oil stays inside the pins of a hollow pin chain which works it's way out while riding and gets really sticky.

Anyway I can't help but think that the chain will be subject to much less internal abrasion with this kind of regular maintenance after seeing how much more dirt is removed with my new ultrasonic gizmo.




I guess I could have just strapped an orbital sander to a bucket- :lol:

Yeah, if you tune it to do 22.000rpm :D

...else, not so much.

You mean you can't reach an ultrasonic range with 12,000 rpm :P

Yes, the definition of ultrasonic is "above the human hearing", so give or take, above 20,000rpm, or 20kHz.

On a more practical note, in my experience, there's a long way from a vibrator to an ultrasonic cleaner, regarding performance.
Once things are sticky, low frequency vibrations are not gonna cut it, or take so long to dissolve that the parts see damage from the treatment.

But most rednecks are hard of hearing so technically speaking anything above 10khz would be ultrasonic for them fella's :think:

Sorry, I'm a hack myself but even this was a bit shade tree for me- a palm sander strapped to a bucket, YEEHAW! The only thing missing from that video is dueling banjos.

It's not a bad idea though, just the wrong application.
Back in the day of flying model planes, I used something along those lines, to get dirt out of crashed engines, without having to take them apart completely.
It shook sand out like nothing else, and the oily part was easily removed with acetone in that case.
Not that I wouldn't rather have had an ultrasonic cleaner back then, but at the time it was the best my financial situation could support.
For a chain, I'm fairly sure it would be in vain though, or on par with shaking it in a bottle of kerosene.

That would make sense for shaking out sand and other larger debris. I was of the understanding that the intended purpose of ultrasonic cleaners was for intricate cleaning and detailing of otherwise impossible to reach areas and that the higher the frequency, the smaller the cavatation nodes.

I have had to do things on a tight budget most my life, but this just struck me funny as it seemed no thought was applied to the operating principle- it's makin' a clamour it must be a workin'

I am under the same impression.

Well, they're kinda missing the "ultra" part, so to speak. ;)
For their intended purpose, I'm fairly sure it works ok though. For a chain, not so much.

Well thanks for your input on this as I feel very satisfied with the results. If I get the time I'll try to post a more in depth follow up possibly with a better/ cheaper diy alternative using an actual transducer as I really want to contribute something of value that would benefit this awesome forum.

Since we're talking like 100W, using the principle of a tweeter comes to mind, for a DIY ultrasonic cleaner.
If you can find an old PA speaker, and strip the driver from the horn, I think you ought to be set.
