have? I want to move a 200lb platform on 8" wheels. Do you think they could do it? My
partner (who also reads this list) thinks I'm nuts to suggest buying two new drills
and cutting them into pieces. My resoning is that their R&D department spend lots of
money making them able to drill 3" screws into 4"x4"s. They should have the power and
be cheap enough because of mass production.
