I am asking $225 for my 2hp (okay it is only 16a, but it could be 2hp)
cannister DC on craigslist but am getting no response. Next try would be
eBay, but I don't want to go there for an item that can't be shipped. So, I
am thinking of recycling it.

Assuming I can get the RPMs worked out, would it be reasonable to use the
motor on my 1hp jointer? Would it cut better with the added power?

Use the cannister and lower bag as a filter on a vacuum? Would the added
filter area help the suction any?
