Yes, those topper laps will work. I am not familiar with that brand so don't know how long they will last. But at that price what have you got to lose? However, you will need a master lap for a backing support for those toppers. For an inexpensive aluminum master lap, if you know anyone that facets ask them if they have any old worn out Crystalite Standard laps laying around, not the Crystalite Steel Laps but the aluminum backed Crystalite Standard laps, that they are finished with. You can heat the Crystalite Standard laps in the oven at 250 degrees for ten or fifteen minutes to soften the adhesive, and then quickly before they cool, while wearing a good pair of oven mitts, use a sturdy blade or chisel to separate the worn out diamond platted topper lap from the aluminum master lap. Let it cool and then use one of the good semi-paste paint strippers that has methylene chloride like Strypeeze or Red Devil (not the bio-crap stuff) to dissolve the remaining adhesive residue from the aluminum backer lap. Let the chemical stripper do most of the work for you by applying a thick coat and letting it sit for 10-15 minutes, If it starts drying out recoat (never let the chemical stripper completely dry out or you'll have a hard time ever getting it redissolved). Then use a piece of coarse steel wool to remove the stripper and adhesive residue. Then clean with lacquer thinner or hot soapy water to remove the remaining the stripper residue. Larry C.

This is what I use. It is a hook and loop backer that you can pull off one disc and stick on a different one in seconds.They come in four, five and six inch (maybe eight?) and the great thing is that there is no center post sticking up. The one I have is for a 5/8 arbor but I think they are available in one half inch. The stone counter top, and some lapidary places sell them. I could show you links to places here in the states but I am sure they are available in CA. If you google counter top polishing you should get a bunch of hits. I have been using them for about three years and am still using the same upper grit pads (1000, 1500, 2000, 3000) that I started with. The lower or courser the pad the shorter the life span but they still last quite a while. I started with four inch, went to five inch and wish I would have gone with the six inch. The first flat lap I built was a vertical pad machine then I built a new one recently that I power with a drill press. I could see a lot better with the vertical but water spray was a real problem. The pan on my new machine is an angel food cake pan and it is not big enough so I am going today to try to find a fourteen inch pan to use. This is the machine without the pan. I am going to have to do some digging to find other photos of the pads. With the pan. This is the best photo I could find with the disc mounted. It is a four inch disc on a five inch backer pad because when I switched to five inch I just replaced the four inch pads as they wore out. I have one six inch pad that was given to me that works okay on the five inch backer. Here is a link to a place here in the states that sells the diamond pads that I use. www.toolocity.com/5-jx-shine-wet-diamond-polishing-pads.aspxIf you have any questions message me because I may not make it back to this thread. Hope this helps Jim
