When I have encountered problems with the inadequate stiffness of the ways
such as when I am turning large diameter steel stock, I keep two pairs of
shallow angle beech folding wedges which I tap into place both sides of the
carriage, between the ways and the bed. This usually solves the problem. I
have the advantage of having an old cast iron DB which has two reinforcing
webs between head and tail which are a convenient base for the wedges. Later
models have a convex centre between tail and head which may be more
difficult to get a good wedge action but I'm sure that our ingenious members
will find a way.

Yes, but the rods have _more_ ability to bend if the bed casting itself is
not bolted down.
Mine is bolted onto a piece of steel tubing. I also filled the underside
of
the bed with epoxy, after putting wire thru the webs to "reinforce" it.
