I bought two identical 0.5x4x36" steel bars from "the worst seller on eBay", a.k.a. Bargainland-liquidation.
Their color resembles various pieces like 3R EDM electrode bases that I have, etc, that sort of thing. Not dull hot rolled iron.
I need something like these bars to form a part of a bridgeport base on casters, however I am concerned whether they are weldable. I do not think that they are stainless, but could they be of some alloy that does not weld well?
i P.S. I am not planning on having casters under the bridgeport, they will be to the sides of the base and I will make sure that the base is only 1" or so off the ground. The casters are rated for 2,400 lbs each.
