I added some stoppers to the bottom of my base. Works like a charm and super easy.
I'm using a Lowe's bucket and it just so happens that the Monster Mill base is exactly the same width as the bucket length and width-wise so it was easy to center on the bucket.
Next, I traced the inside edge of the bucket. Leaving the mill unattached makes this part a breeze. Keeping pressure on the base prevents it from moving.
Here is the bottom of the base with the edge traced. I used Nylon Spacers from Lowe's (in the metal drawers in the hardware isle). Rubber grommets or stoppers would also be a good choice.
Any screw that fits inside the spacer would work, just make sure it wont go all the way through the base.
I eyeballed the layout and marked where I wanted them.
Pre-drilling the holes. Again, don't go all the way through!
All done! Less than $5 in parts and less than 15 minutes in labor! Do it!
