what vacuum to use?

Post: # 16772Unread post **folk** Thu Oct 20, 2011 2:58 pm

I've had a helluva time trying to find a good vacuum pump to rig up for my cutter.
what do you use?
photos?

Anyone have suggestions?
perhaps something that isn't hundreds of dollars?
thanks

these pumps from thomas are very good:

but not to quiet, put it in a box or in another room...

I use the Hoover my mother had when she was student ...
I putted a big resistor to down a bit the voltage , and it works perfect since many years ...

cost =0

I think dietrich is a experimented cutter , because I was thinking to upgrade for exactly this model ...

I just ordered this one, so we'll see how it goes;

If I could afford it, this really looks like the more pro way to go;

you don t need to spend money for that ... try to find a old one ... you won t have a better sound buying an expensive vacuum ...

for sure - but having a super loud vacuum around while trying to enjoy the art of cutting records sounds like no bueno.

Folk, how did the "Metro Vacuum ED500 DataVac 500-Watt 0.75-HP Electric Duster 120-Volt" end up working out for you? I have to buy a vacuum.

And....

Being a bit of an electronics dunce myself, what sort of "Variac" is appropriate to add to a vacuum? One of the ones listed here? or some Neumann thing? which?

I use a Staco 3PN1010V

A Variac is simply a variable voltage transformer.

Those Stacos with digital readout look amazing. Nice for adjusting the back massager while on the nuclear submarine.

Staco have a general information page on variacs:

I have a very quiet little vacuum I plan to cobble into a swarf collector one of these days.

Post: # 18488Unread post d Sat Mar 03, 2012 3:26 pm

i use compressor from the fridge. well just started to use and testing. . i got small one for free and it is working. noise level is good. just need to put in some kind of box and will be very nice.

sometimes you can get fridge pump for free. maybe some sort of ECO electronics collector could have couple to try

OK, that's good info. Vacuums are often not quiet. Make and model?

My vaccuum motor is built into a wooden box housing that seems to be original. The vaccuum itself is a modern replacement that I can get the model number off the box it came in. Would have to dig up the box...

Anyway, I have my wooden box wrapped in soundproofing foam material that you can get at any Guitar Center in large sheets. I made sure not to cover the air intake slot on the wooden box. But the rest is covered.

I also used the same material to cover a lot of the the underside of the table the lathe body sits on. And, I also used sheets to cover the front and back covers of the lathe cabinet.

End result is that I can barely hear the vaccuum while running. I mostly just hear the sucking from the tube. I don't have the ability to put mine in another room as a number of cutters do here.

I'd love to know!

So, in other words, you have a homemade wooden box with a vacuum motor built into it. And then I reckon you have some sort of jar collecting the swarf? Otherwise, how to you keep the swarf from getting in the motor?

The LS-76 has a tall glass jar, with a coarse fiber filter at the top. The hoses to the chip suction tube and the turn table hold-down holes for the blank disc have a hose which leads into the top of the jar. The chip tube extends below the filter. A larger hose also goes through the top which supplies suction from
the pump. A little like a narghila, the suction pulls the debris into the jar but only filtered air goes to the pump. However, unlike the bubbler, the water in the jar is well below the end of the chip tube. The water is just sort of there...

A small amount of water is meant to be kept in the bottom of the jar so that the partially-vaporized chip (from hot stylus plowing) will not become unwieldy and escape. After the jar is about 1/3 full, one empties it, carefully/responsibly.

Here's the Ametek pump that's in the LS-76 vacuum box:

http://shop.centralvacuumfactory.com/lamb-ametek-115750-2stage-vacuum-motor-volt-p-224.html

Over 18k rpm! Not as fast as the 250k rpm stylus polishing machines, but the sound is still loud enough to make you think of a jump jet or similar.

There is a felt gasket around one of the square edges of the box and the side of wood that goes over it can only be "mostly" screwed down. The air which is pulled into the box escapes through the cracked opening.

Using a 3M industrial vacuum. It's too loud, I can't hear the machine over the vacuum's racket. I run it through a variac transformer, about 90 volts for passably good suction. I might consider the above-described swarf trap and run the vacuum off to the next room.

Is it common for the stylus to cool down when the vacuum is running, even with stylus heater wires operating? I just noticed that my needle tip was cool with vacuum on, but it got hot enough to singe my skin with no vacuum.

I had to pull it out of storage to find out what exactly it is. It's a G.E. MV1 c.1965 - long discontinued. It was apparently one of their first compact hand-held vacuums.

(I was originally going to use it as a wind supply for a small pipe organ, but the flood nixed that whole project for the time being.)
