Steve, if you have some angle iron like 2x2x1/8 I know it will
work. The 1/2" flat strap will probably work just fine, but
smacks of overkill. The angle iron would give you an easy way to
add a wood shelf for a bit of extra storage for tool specific
accessories.

I have a large commercial sewing machine, a Singer 111W155. It
has a base with the treadle, and a large motor. I would guess it
weighs about 130#. The legs come down straight to big grommets
that sit on the floor.

I want to put two pieces of half inch thick by three inch wide
flat bar across the bases front to back, mount them to the bolts
holding the grommets on, and have them extend out so I can put
swivel casters on it to move the machine around better. This is
going to improve the width so as to make it more stable, but not
the length.

How much flex would be in the flat bar? The flat bar would
extend past the current edges of the feet by about four inches.
I think the flex would be minimal, and that it would hold, but
wonder if I should weld on some diagonal brackets made out of
simple rods. I could weld them on, but then it would be
difficult if I ever want to remove the wheels. I could make
them to bolt on, but that requires more work.

How much flex?
