Polishing a Large Puddingstone

Learn how I polish large puddingstones. • Here are the steps I took to polish this. • I started with my normal, dry angle grinder. The cup wheel is 50/60 grit, but is way more aggressive than the soft 30 grit wheel I followed it with. The angle grinder also spins much faster than the wet stone polisher. I spent 17 minutes shaping the rock and removing holes in it. • Next I moved to the wet stone polisher. This has a soft backer, so the pads can flex to the shape of the rock. The grits and times are as follows: • 30 grit - 40 min. • 50 grit - 11 min. • 100 grit - 11 min. • 200 grit - 11 min. • 400 grit - 8 min. • 800 grit - 11 min. • 1500 grit - 10 min. • 3000 grit - 8 min. • At the end, I used a cloth polishing wheel with aluminum oxide polish. I think I'll skip this step in the future. I don't think it made much, if any, difference. • – MERCH – • https://michigan-rocks.myspreadshop.com • – FACEBOOK – • / michiganrocksrob • – INSTAGRAM – • / michiganrocksrob • – KINGSLEY NORTH – • Kingsley North is a lapidary store in Michigan's U.P.
