Hi guys - made this while waiting for an ultrasound cleaner from Aliexpress. I used a 300mm lazy susan ($19.95 from Bunnings), some scrap ply, screws, and a 75mm M8 bolt, washers and nuts, for the base - and some standard plumbing fittings for the wand. The lazy susan is obviously not a high quality unit (although it was rated for 225 kg load!) but it does what's needed. I cut the slit with a battery powered skilsaw, and glued some David's Emporium foam around it. The mat was cut from some non-slip drawer liner, also from the treasure-trove that is David's Emporium in Hamilton ;-) I had to reduce the diameter of the bolt to fit the record spindle hole. My Ryobi workshop vacuum cleaner completes the picture. I have only tested it on an unwanted LP which I washed in the kitchen sink ;-), but the wand worked well and the noise level WAS slightly reduced. Hopefully the combination of ultrasound and vacuum will be HYPERBOLIC!!!
PS the comments under the images haven't come through - the first image shows the wand in normal working orientation, the second shows it upside down so the slit and foam can be seen.

I'm loving the LP cleaning kit! All albums benefit, some more than others. I managed to tame the buzz somewhat by inserting pieces of inner tube rubber at the 4 corners between the kit and the ultrasonic cleaner. The only other improvement I can suggest is the inclusion of a compliant worker who loves cleaning records and goes home at night. Cheers Owen for a great bit of kit ;-)

Sound-damping of the tank is something that I should try working on, some ideas. My immediate feeling is that the sheetmetal tank box could do with some damping?

I thought ultrasonic cleaners worked by having transducers attached to the tank?, if that's the case presumably the tank would have to buzz/vibrate? Perhaps you could isolate the tank from the rest of the machine though?(but probably need to keep an earth connection I guess), &/or put some kind of soundproofing on the outside(if it wouldn't overheat)
The vacuum setup looks cool, is there no issue with static being generated by their passing through the slit/tube?, if not I might try something similar myself

Static doesn't seem to be a problem - after vacuuming I usually leave the LP's in the dish rack for 5 minutes air-drying before slipping them into a new sleeve, and I don't see any evidence of static buildup. I'm not sure what the material I used around the slit is composed of, but I could check with Davis's Emporium if you're interested. It's closed-cell foam of some sort. I guess the contact being wet/damp while vacuuming lessens static buildup. If you want I can supply details for the lazy susan from Bunnings, and pipe and fittings dimensions.

I vacuum as well, after us clean, but use an old manual Nitty Gritty RCM to vacuum with. Works a treat. I clean 3 LPs at a time, place them in a dish rack after cleaning, reload the US RCM , then vacuum. I did experiment once leaving out the vacuum cycle, but results sonically not the same. In my experience, if the record has no physical damage, the process results in perfect extraneous noise free play back.

Almost the same process as me - I don't wait to vacuum though - I figure that if there is any dirt remaining it is going to be removed more easily while in suspension. And yes..the noise reduction is impressive - it's nice to be able to silence my inner sceptic too

I vacuum immediately too - the surfactant / detergent makes the fluid dry off so fast that I have to work fast to vacuum 6 sides before they evaporate dry!

Another one for immediately vacuuming after an US clean.
Takes less than a hot minute to do three

Cool, thanks for the info. I don't need any specifics, I'm just getting a general idea, thanks for the offer though.
