I have ordered more sets of 5" casters from Surplus Center after seeing how well the first set works on my new shop cart. I am planning to use some 3" angle iron I got at an auction years ago to make mobile bases for the table saw and 6" jointer so I can move them around in my new shop building next year. Now while I still have a 50 amp line for the welder seems like the time to do it.
I have never had a mobile base under a jointer before and am wondering how wide it needs to be at the bottom to be safe from tipping over. The jointer is a Jet jj6csx. If I could put the casters under the corners of the current base that would seem ideal, but the caster will raise it up 6" or so, and I don't know if I should be planning to extend the width of the base. This would seem more stable against tipping but the casters would stick out right where I like to walk when using the jointer, so that would be a bit of a nuisance. If anyone has any advice I will be very grateful.
