Hi! New member here.

I decided to get a Ameritool Grinder/Polisher. (Next month) Here's my list and a few questions.
(Sorry if they are obvious, but this is new to me)

1) Ameritool Universal 8" Complete

Includes one 180 grit diamond lap, 325, 600, & 1,200 mesh diamond sanding discs, polish pad with 14,000 diamond compound, and four backing plates.

2) 80 Grit 8" Diamond Facet Top Lap NON PSA

3) 8" Backing Plate
 
4) 8" Sponge Discs  x 4
 
In the package it jumps from a 1200 mesh diamond sanding disc to a polish pad
with 14000 diamond compound . Should I add another mesh/grit in-between?

On the sanding discs, do I have to stick them on the backing plates or can I just place them on and tighten down the
knob to keep them in place?  I've read they are a bugger to get on and if not placed exactly they will not be
balanced and cause problems. Yes?

On the sponge discs, I  can use these under all the sanding and polishing pads?

Anything else recommended? (besides winning the lottery to pay for it all - LOL!)
 
Thanks,

James

The sponge pad goes under the felt polishing pad. No need for an extra lower grit polishing. Now I could see a felt with ZAM on it for turquoise and other soft stones. It is used dry. And yes you have to stick the different grits down.

Thanks for the reply!

Can I also put the sponge pads under the sanding discs?

O.K. I don't need the 3000.

Was thinking about another polishing pad (felt, or leather, or ...) Will look up ZAM.

Was hoping I didn't have to stick them down. I have seen PSA and Non-PSA discs. Do the Non-PSA
discs have a rougher backing so the don't slip not being stuck down?

Thanks again.

"No more trains will be sold once the magazine leaves the station"

Well hello James, small world.....I'm in Toronto, Canada.....Leaside Area.....we're neighbors.
I have an Ameritool 8" Flat lap that's just like the one you're describing.
I tapped into Krystee [aka TNTMOM] when I bought mine, as she is the "Queen of Shine".  You could look her up in the contacts page and send her an email.  She's unbelievably helpful and nice.   Also when you go to her 'contacts page' [under 'members' near the top of this site] you'll be able to see all of her posts.  Worth reading.
Actually, seeing the stunning cabs she produced was the real reason that I bought the Ameritool Flat lap.

Re the sponge pads - she told me for years she didn't know about them, but once she discovered them she uses them under ALL her sanding 'discs'...especially the finer grit discs..... not the rigid 'grinding discs' though.
They make it easier to get smooth transitions as you shape cabs.

Re 'attaching them' YES - they come with a peel off back, that's VERY STICKY.  Once the back is attached....it's attached!!!  and you don't take it off till it's 'shot'.
Apparently, according to Ameritool, when they are shot....you soak the disk in warm water and the glue will soften, and then you can take the backs off without too much difficulty but don't expect to put them on and off once they're stuck. 

So.....to put them together, you take the black 'backing plate' and the gray 1/8 inch thick sponge disc with pressure sensitive adhesive backing, you peel off the backing and put that in place, and then you do the same to put the coloured diamand sanding discs on top of that.

Because I was ordering if from Ameritool to be delivered to family in the states, I asked them to verify that everything was 'working properly' with no 'issues' before they shipped it, and 'as a wonderful gesture of good will' they pre-stuck the coloured sanding discs on the backings for me and cut out the holes......but they didn't put the sponge discs I ordered in between....[ergh], so I mentioned it to Krystee and she just said [also ERGH] that I should just leave it that way and work with them [as she did for several years] until they wear out, and then put the 'whole sandwich' into place when that happens.  They still haven't worn out.

As noted by hulagrub, you also put the sponge pads under the white polish pad....and also under just a piece of scrap leather, depending on what you're polishing.
I bought some lovely leather scraps at a place on Spadina, called Leather & Sewing Supply Depot http://www.yelp.ca/biz/leather-and-sewing-supply-depot-toronto .  They have a 'scrap box' that's HUGE and the pieces are large enough to make several leather polishing pads [for various polishing compounds]. 
Those leather pads need to be glued on though with something like Gorilla Glue [which you can get at Home Depot].

Another neat thing to see are some Youtube vidoes that Krystee did for me, showing her method of [non-dap] holding cabs using the Ameritool Flat Lap.  Very helpful  - yes
and also Part 2


Krystee is a total doll and 'my guardian angel' when it comes to Flat Lap work on an Ameritool Flat Lap.

Boris [aka Gemmy] is also from Toronto, Canada, and very knowledgeable about Lapidary [but doesn't use a flat lap for cabs].
 
Good luck,
Let me know if I can help you with anything.

Thanks!

That's great info. And love the videos.

I guess I should get a couple of spare backing plates and sponge discs over and above what I need at first. That way if I get the leather or whatever later on I don't have to order form the US again and have to wait for them to arrive.

Thanks Again!

You can use 3M Feathering Disc Adhesive to attach non-PSA discs and leather or other materials to the rubber pads.  One advantage is that you can peel them off easily and re-stick them if you need to.  Lapidary supply places carry it and I've seen it in automotive stores. etc.  You should be able to find it in a store by you I would think.

Actually, you're totally right Hummingbirdstones......it WAS 3M Feathering Disc Adhesive we used.   bricks
Boris [aka Gemmy] had some of it and I didn't so he told me to bring my disc and leather to a trade show [where he was manning a booth].  He used his glue to stick down my leather properly and then I trimmed it to size.  ura It wasn't the Gorilla Glue.  Thanks for recalling my memory. yes

Thanks!

Anyone use the Diamond Lapidary Faceting Flat Laps they have at Amazon?

They are sold by HANS LAPIDARY TOOL AND MACHINE.

Not the metal (aluminum I guess) ones.

1.1 oz., flexible, and stick to the regular backing plates so weight should not be a factor for the Ameritool.

I figure if I need more discs later I can get them there.

Thanks,

James

O.K. Making up my list and am still confused a bit on the discs. JS Gems has both PSA (sticky) and Non-PSA (non-sticky).

If you don't get the PSA ones do the Non-PSA ones just sit on top of the backing plate?

What keeps them from slipping if they aren't stuck down?

Thanks

Hi James,
I've only used the PSA ones but I'd think you'd HAVE to glue down the Non-PSA ones with your own glue.  Otherwise, I'd think they'd get all 'weird' and possibly flap around' when they were spinning that fast ....not to mention the water bath that would probably splash on you if they weren't affixed to the plate.
Personally, I'd get the PSA ones because that glue is not too cheap.

O.K. I see, they have to be glued down either way. The PSA come with the glue. The Non-PSA you supply your own glue.

Yeah, will get the sticky ones. Pre sticky and the glue evenly spread on the disc as well.  ura

Thanks!

O.K. Confused again. LOL!

The package deal comes with sanding discs. I am on JS Gems web site but I cannot find
any "sanding discs". They have "Diamond Facet Top Laps" in various grits. Is that what
they mean when they say sanding discs in the package?

Also, are the  "Sanding Discs" and/or "Diamond Facet Top Laps" flexible or rigid?

If they are rigid will the sponge discs still be needed?

Thanks,

James

Hey James,
No worries....but my brain is 'totally fried on something else', so I'd suggest you compare the ones on JS Gems with the ones here at Ameritool Inc.  http://www.ameritool-inc.com/store/index.cfm/category/2/polishing--sanding-discs.cfm
I wouldn't want to steer you wrong....because of my 'fried brain' just now.   hide Good luck. yes
