Today I'll be welding on the leveling legs and 1/4" C channel which determines if the machine will be raised by between 1.5" to 2.5" depending on where I place them. I've seen some posts on here about people raising similar Rong Fu 45, Grizzly's, etc 6 inches or more which seems alot, Im only 5'9" ... please share your thoughts about whether i should go with 1.5 or 2.5"+ of raise . Thanks much .
