Guys I need to make a mobile base for a jointer that weighs around 1000lb plus.The base has two sections that I can construct two bases w/4 wheels for each section to help w/ the weight.I have a welder and some 2"X1" tubing,but I am wondering about the wheels.I would like some low profile if possible,or maybe 2"-4" wheels.What type of wheels would you suggest for this project?Should I get the ones w/ steel,rubber,plastic,what ever else there is.And where could I purchase these?I have look on e-bay,and casters are there by the thousands.Some wheels there have a rating of 450lb per wheel.And the floor in my shop is concrete.If you have any pics of your mobile base for something this heavy,please post with some pics your thoughts on this.Hope everyone had a great Thanksgiving as I did.Thanks again guys for the help.
