Yes, separate plates for each grit.
That isn't the same machine shown as on the Covington site. The hub on yours is designed to hold disks down against the plate. The hub on the laps for grit are different. These big grit laps have a V shaped channel with a drip can/tank or other water source for the grit to drip down on the plate. A paste or non-renewing slurry will be thrown off of it and you'll end up sliding your stones against the steel without cutting.
If your machine has a water supply without the trough to hold and supply loose grit then it is intended to be used with disks.
Loose grit is much cheaper and often faster then disks but you need to seriously clean the whole machine very time you change grits. I mean like take it outside and hose it off and then hose it some more. Even one or two stray pieces of 120 grit in the mix when using your 300 or 400 grit will leave a pretty noticeable scratch on your piece.

You don't use grit on this machine. You'll need to get more removable pads that have different grits. Start with coarse and work your way to the finer grades.

Thanks for the replies!
What you see there in the photo is all that's left of the original packaging which was a plastic tub like a 1 lb margarine container. I don't see any AO on the label. The material is a very fine white powder similar in texture and feel to cerium oxide, I don't have any AO or TD to compare it to.
Both my flat lap and felt wheel I use with cerium and don't want to mix different polishing compounds on them which is why I'd like to know what it is.

This may be the wrong board to post this on but Does anyone know what the polishing compound (part 4) is from Lortone's 4 part polishing kit? I couldn't find out from their website. Thanks Attachments:

At just 50 or 60 psi Tungsten carbide sandblasting nozzles erode at a noticeable rate. There are boron tips that'll last longer but cost more. I don't know if they'd hold up well at a few thousand psi.
As a side note there used to be a youtube video of a guy slurry blasting the paint off the molding inside his house and then complaining about the water damage. He said he posted it as a complaint against the manufacturer who didn't add a warning about using it inside. you can probably guess what the comments were like.

Try hooking your hot to #4 and your neutral to #1. Take note of which direction the motor turns. Then switch your hot to #1 and your neutral to #4 and see if it turns the other direction. the wiring inside the casing shouldn't be messed with unless there's a short. On the backside of that board with the connectors on it it'll be wired up so you only need to change the connections on the outside.

I did find pictures of those BD Rock Vise' and they're like a hand screw laid on their side which would be an easy thing to make.
I was thinking of using a canvas bag packed with old sand blasting grit as a base to set the pieces on. it should conform to the shape and once it's wet won't move around easily. has anyone tried that or something like it?

Thanks, I was hoping for something home made but this is a good start. I've already found on a wood workers website, how to make home made toggle clamps. lumberjocks.com/projects/16919Maybe some sort of variation of a hand screw can work as well.

First post here but I've been lurking for a while.
I would like to know how people here clamp their pieces onto a sliding saw table. I'm using a 10" MK tile saw with a sliding table but there isn't anything to hold the pieces down and while I guess for tiles you may not need anything but for something 2 or 3 inches thick it would make things a lot easier. I'm working with glass not stone so I need ideas that won't scratch it up.
Thanks a lot! Pictures would be a great help.
