I have a live edge cherry slab that will become a bench shortly. Rough sawn and needed quite a bit of stock removed. Too much twist in it and too wide to go through the planer.
Decided to sand it smooth and since I was short of sandpaper I went to Amazon and found a 100 pack of cheap assorted 5" discs hoping to get lucky and get the job done. $16.00
What a surprise! I used 2 60 grit and 2 120's and the job is finished.
Never before have I bought cheap paper and been happy with it.
I have enough left to supply my needs for a few years!
