The bucket is a standard 5 gallon bucket available at any home improvement store. You can mark it with a marker to whatever size you choose the brass hopper to be. The housing is made of MDG. You can make the housing any size you choose. I choose to cut my peaces at 45 degrees. I recommend that you experiment with angles and choose the one that you prefer. I did not document how I cut the housing, I just did what seem right to me.
