DIY record cleaning machine (RCM) consolidation and resource thread

I cannot think of a reason it would not work, particularly for one motor. If two, the motors would have to be synchronized *exactly* or they will fight each other.

I use a very similar motor for my RCM, but 12v and 18RPM (or something like that). It is hooked directly to a hockey puck which serves as my "platter" (with the underside of the record floating in space - a design preference on my part). I run mine on lower voltage and I get about 6-8RPM, I think. I like that better, though now that I have cleaned a lot of records I have considered trying it a little bit faster to see if the results are satisfactory.

Hello dodog, I certainly can! For a single direction I'd recommend this A/C Dayton gearmotor. For bidirectional rotation I'd recommend this DC Dayton gearmotor. I used the later in my DIY RCM build. :yes:

Here are a couple more from McMaster, About half way down the page. "Compact DC gear motors" between $45 and $38. Torque specs are similar. A 12 RPM motor has 40 inch pounds, a 16 RPM has 25 in/lbs. 12 VDC reversible.

I think you could get away with a wall wart to power those motors. They are all under 2 Amps. (2000 mA). There is a 12 VAC 2000mA wall wart for $20

I'm not an electrician. It would be cool if someone with a bit more knowledge than I pop in and verify if this is correct and safe. But if so, you are looking at a motor and power supply for @ $65 bucks.
 
Whats up guys? I'm building an RCM out of an old Technics SL5 Direct Drive, gonna mount a VPI wand on the side using some PVC tubing and whatnot. The first thing I noticed about it when using it to clean my lps with my cleaning brush is that the turntable would stop spinning with not too much pressure applied. I remembered seeing posts here about upgrading the motor and I see the ones above in this thread but my question is do you think one of those compact DC gearmotors could fit in one of those SL5s? I think I've read that people have used those as DIY tables so I figured I'd ask. Thanks all

Hi Sanc, there are many small DC motors and hard to make decision. Here is a rough criteria I think it may use as reference.

12-24v DC
about 10-15W
without gearbox turns 300-400rpm
with 1:10 to 1:15 ratio gear box.
If you use a home vacuum, this spec should able to turn the record without losing too much speed.

Size of this motor should be compact. If the motor is too thick. You can raise up the turntable by rubber stand or wood stand to fit the motor underneath. Hope it helps.

Frank.
 
Thought i would share my DIY cleaner that I just finished. My goal was to fit it in a califone box so it could be portable. For a motor I used a black and decker appliance called lids off. It had a 120v DC motor with a gear box all built into a plastic box. The vacuum was in the garage when i bought my house 4 years ago. And the platter is from a crappy sanyo turntable that i had laying around. The speed is probably around 10-18 RPM's with way more torque than you need. It dries the record 100% in one revolution. I'm pretty happy with how it turned out but thought i would get the opinion of others that have taken the DIY path.

You wouldn't know of anywhere something like this could be purchased with a gearbox of 20> rpms?

The compact DC motors look good. I'm looking at the 12rpm/40lbs torque or the 16rpm/25lbs torque. Anyone have experience with anything like this? I'd imagine 12 VDC would be fine as opposed to 24.

hello Sanc, the link below is the spec of Japan Servo motors. Most of the motors and gear box will meet your spec. Click on the model number will show the detail. You may have to find the local dealer.

Thanks for the link. Just picked up a shop vac from Lowes and wrapped my VPI wand & arm with electrical tape so it would seal in. Not a real RCM but it is working just spinning the platter of my cleaning table. Will get me by for the time being.
 
Does anyone have any experience with these type of motors? I started an RCM project a while ago but got stumped once it came time to find a decent motor. Would this work or should I continue trolling the thrift shops for an old ice cream maker or Lids-Off can opener to dismantle?


Here are the specs:

115 VAC 15 RPM GEARMOTOR
MERKLE-KORFF model 3715UP-250 compact gearmotor.
Thermally protected, shaded pole motor. Metal gear housing.

SPECIFICATIONS Speed 15 RPM
Voltage: 115 AC
Amperage: 2.7 Amps
Power: 97 Watts @ idle
Rotation: CW
Duty: Intermittent

I'm sorry...

I know I shouldn't litter. This thread looks really nice and clean 'till now, but I just had to share this. I haven't been very good at vinyl theory, but I'm new and working on it. Coming across this thread I thought I'd get an overview and googled record cleaning. Here's something I found (3rd hit on google), and even I got a little sad: http://www.instructables.com/id/Cleaning-Vinyl-Records/
What really stood out to me after reading several of the threads mentioned here (now thinking I understand a little bit) was the "Dish soap (any kind will work)".
Sorry, all done now... I'll stick to reading stuff I find here for a while! Thanks for a great forum by the way!
 
SOMETHING IS WRONG I just went to page one of this thread and I got a full page alert that there is Malware on the page or something to that effect.
 
Whoa! I just got that, too. Chrome, here.

EDIT: I took a screenshot and sent it to Ernie and Dave. Maybe they can figure it out.

I get that same warning all the time on this site, I can't download any pics if I try to upload a pic from my PC. I can only post pics from my photobucket site. Many times I get that same warning and it kicks me out of this site as my pc says it is directing me off this site due to a dangerous malisous malware. (excuse the spelling) I notified a moderator of this problem a few weeks ago and he said he would look into it, have not heard back. I am not using Chrome, I am using IE, windows 7 64 bit.
 
I got a question...my wand is a 25mm pvc pipe. I obviously didn't have the slit wide enough as I over heated the vacuum and it shut off...how wide should the slit be to prevent this..?

Cheers

Dave

I measured the slot on my VPI wand and it is 10mm long and 1.5-2.0mm across, as near as I can tell with a little ruler. (No calipers or anything that sophisticated.) I am not sure if that is enough to make your vacuum happy, but I use a small (1 or 2 gallon) Sears Craftsman wet-dry vac which has a separate cooling fan for the motor and I've cleaned dozens of records at a time with no heat problems.

Hope this helps!
Don
