I bought two identical 0.5x4x36" steel bars from "the worst seller on
eBay", a.k.a. Bargainland-liquidation.
Here are the pictures of one of the bars:
These bars are very rectangular, have sharp straight corners and are a
little brighter than usual steel. They are strongly magnetic, though
possible a little less than regular steel (not easy to tell).
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?
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
