How to add 4 Wheel casters to a Grizzly G0490 Jointer

[Anthony Whitesell]

I have the Grizzly G0490 jointer. It has an integrated mobile base The mobile base is one of those 3-wheel styles with two fixed casters and one swivel caster that also raises/lowers the machine so it can be moved. With the machine being so long and my shop being narrow, the fixed caster makes it a pain to turn it around to position it for milling (really) long stock (4'+). Has anyone built (or purchased) a mobile base for the jointer that has four swivel casters? If purchased, from where, which model? If made, any chance you can post some pictures?

I have the 12" model and built a base with 3" X 1/4" angle steel and Great Lakes leveling casters. Moves easily and I only need to lower the "feet" when surfacing heavy(er) slabs.
