Hello, I’m just thinking about taking an Excenter machine with 8mm or with 15mm hub. But I would like to use small ones instead of the large 135er polishing sponges, so that I can get the 10cm to narrow positions. Can I actually do this with a 15er or is the 8er so much more suitable? So a smaller support plate also fits on a 15er hub machine? Or what is the best choice for? Greeting
