anyone ever try to make a rotessire out of two engine stands?

also you need to take the angles into consideration. most engine stands have a slight pitch to the pivot.
i built mine from scratch, and would again. you will spend more time trying to make those stands work.
most metal supply shops will cut the pieces to any length ( sometimes even cut angles for you) for no charge.
all said and done with 7 Very heavy duty castors and the steel i had about 250.00 in mine.
