Hey All,
So i just got myself a new abbott and ashby 8" bench grinder, bought along with that a tapered spindle, a stitched buffing pad and a loose buffing pad, some Brown cutting compound for the stitched and some White SS compound for the loose buff.
Fitted it all up and gave it a go for a small 5 minutes or so for each different Buff and compound (one section about 200mm square), stopping to wipe it all clean with Turps before starting on a different compound.
Found the actual side/edge welds came up quickly to a mirror finish but the flats sides of the washer bottle i was doing seems not to be changing much if at all with the use of the compounds and wheels.
my basic Questions are :
1. With brushed alloy material should i be using a sisal buff with a grey compound first to remove the oxidisation from welding then moving down the compound towards to mirror polishing loose buff?
2. Is the grey too harsh and i should spend more time on the brown compound before going to the white?
3. Whats an easy way to tell if more compound is required on the buffing pad?
4. could starting with a 400 or 600 sand paper assist in the polishing process? EDIT : now reading that you can use 400 - 600 - 800 - 1000 grit wet dry prior to final polishing 2nd edit : now reading that using higher than 400 grit is a bad idea - sigh
Any answers and hint would be good.
Cheers
