Step 4 Building the base Step 1

Cut out your plywood base like the pic, or as long as you keep the top and bottom the same size you can make it whatever shape you want, it will be up to you to determine if you can fit the motor in it.
The top piece is 12" square with the hole centered in it. I recommend laying the two pieces on top of each other and drilling the four support bolt holes at the same time so they line up perfectly.
