I know alot use walnut media to clean brass. Question i have. I can get walnut branchs and the stump removel mulch from company friend works for. Next week they start on 3 week job cutting black walnut trees for a house and front yard. How fine would it have be. To use as walnut media. They will run branchs threw a chipper and let me use another machine to make mulch alot smaller. Then how dry does it have to be. Be more i could use in a life time they estimate close 1800 lbs could sell cheap or give away. They said can rent another machine $35 a day can adjust how big small grind it. And would it be worth it
