Help please with polishing problem

Hi, I live in the UK where Lapidary is now as good as dead,machines are no longer manufactured and good cutting material is very hard to obtain. I solved the latter by buying large pendant beads to cut 40x30 cabochons. I cut these using diamond hand tools.I trim the preform on a tile saw with a diamond blade then with a 80grit diamond disc laid flat on the desk I take the preform down to a 40x30 oval. A Dremmel type tool with diamond burrs is used to angle the top edges then domed with small 120grit flat diamond files. Very smooth diamond files are then used and finally 1200 silicone wet and dry paper. All this takes a long time on agate but I am happy with the results until I get to the polishing stage. For this I use small hard felt pads charged with 50000 diamond paste in the Dremmel.I get a polish but cannot get the high polish I should get on agate. I now have to find space in my garage to set up a old 8" double grinder. I have 50000 diamond paste, tin oxide and cerium oxide but no attachments to use any of these with. Can anyone please advise me on what attachments to make or purchase and the best way to use them to get the high polish I need. I also need help please with the size of the pulleys required for the correct speed for sanding and polishing'
Thank you for any help you can give me.

Dave
