Totally understandable. If you're using that small of a grinder may i make 2 suggestions. Dont do the on off method to load the wheel just hold the compound to the wheel until it takes with enough pressure to create friction thus heat, but not too much that you cause it to bind. Once you get it to take the first time and it gets used, it will take compound much better. Since you are doing smaller parts you should be ok, but i'd use 6 inch wheels and pickup a shaft extender from caswell to give you a bit more room. You are right about the sanding, any higher than a 600 is pretty much a waste if you use a sisal and emory compound. Polishing takes time and lots of tweaking of your method. I have only been doing it for a year, and a year non stop yet i still do not consider myself a "professional" polisher. Snap some pics, we'd all be interested in your results and it helps to trouble shoot problems. Good luck.
