Not on my watch...
Harman P35i 23.5 to 19.5 hopper conversion..
First, mark the height
Then, cut out the shape. MAKE SURE YOU REMOVE THE HOPPER LID SWITCH CORD BEFORE CUTTING
!! Notice that I have my vacuum running at the base of the hopper.
Remove the side walls and flip the shape up-side-down. I Cut off the 90° fold tabs.
Seam tape the hopper closed and re-install the hopper lid switch cord.
