[Shop-talk] technical question about force applied to mount

[eric at megageek.com]

OK, here is my question...

I have this tire changer...

<http://www.harborfreight.com/portable-tire-changer-34542.html >

I can't mount it in my floor (I have radiant heat floor with pipes running 
in it.)

I want to mount it to a metal 'arm' like mount that I can clamp to my 
welding table (at 3 tons, the table isn't going anywhere.)

My question is, what kind of force is put on the base of that tire 
changer?  I'll be about 5' away from the mounting point, so I'm trying to 
figure out how big of an arm I need to make.

Or, does anyone else have any ideas on how to mount this changer so it is 
movable?

Thanks in advance.
