Hi Jim. I couldn't get it that high in that spot because the motor would hit the roof. Bit It is a nice thought to raise it more for a larger container. 2....I would get lazy and wait till they are both full.....then I would be complaining about so much saw dust....oops, "wood dust" I had to take out.
Mine works great with the reduction at the sorce. I couldn't get the 7" sprial here locally so I dropped it to 6" which works great but since yours is 8" you should be able to get it locally. & is an odd size I was told. The joints, too are about 1/3 the price from the local guys over mail order
