polishing with marine carpet
« on: February 15, 2018, 03:22:09 PM »
I have a 21" vibrating flat lap and am trying to use marine carpet for the final polish. The polishing medium sinks away and no shine is visible after 2 days. Using water is the only way the rocks will move but it carries the tin oxide away. Any suggestions?

Is the carpet secured?  How thick is it?

The Lortone polishing pan actually sticks the polish pad to the pan. For other brands, they make them very slightly oversize so they kind of wedge in and dont move about while the machine is operating.

You will need more polish initially to charge the pad - then just top up as required.

Other members will hopefully have other suggestions you can try as well.

Thanks Leah,
the carpet is very low profile (not plush). I secured the carpet however when I took it out yesterday there was about 10mm or water and ali oxide sitting in the pan.

It's very good with what you are doing right now.

i use 3mm thick felt, soak it in water, shake out the excess water, put it in the vibratory lap machine, put in 3 small sugar spoons of polishing grit, spread it around, turn the machine on for a couple of minutes, then add two more spoons of grit, put stones in, turn on machine, add water, when stones are moving stop adding water. Bunnings sell a black marine carpet, a metre wide, use it upside down, gives good results also.  :)
