Here
is a mockup of an end assembly. The 1"
DOM tube runs between the end assemblies.
It is going to take a lot of work to get the
mill scale off the 3/8" steel.
I have already
tried my 4" angle grinder with 36 and 80 grit
. I also tried my DA
sander. Each did a little, but not
enough. In hindsight,
I should have had the
steel plate sand blasted clean before doing
all the cutting.
The 1/4" is not as bad. I cleans
up easily.
