[rescue] WAY OT: sliding rails - centermount

[Greg A. Woods]

The only way to mount sliding rails on a relay rack is to use a pair of
hunk-o-steel/alum. plates with angle-iron rail ears firmly fixed to them.

Smooth out the wiggles, adjust and re-shape to the size of the chassis
and for the weight you have to carry (good mech-eng. and/or metalworking
references can give the sheer strength of the plate and angle iron so
you can figure out how many screws you need on the rails, etc.)

The vertical bar is the angle iron (sticking out of the screen...  :-)
The row of equal signs is the rail, and it'll be screwed to the plate on
the opposite side of the angle iron..

You have to keep this whole rig quite thin too -- relay racks sometimes
have less clearance between the rails than ordinary cabinet rails do
(even though the mounting hole centers are the same distance appart).
Mounting the angle iron in such a way so that it doesn't go inside the
rails helps.

It'd be much better to just find/make a pair of correct-sized ears to be
center-mounted on the chassis and then bolt the thing directly to the
rack rails.  They might even look like above, but without the rail.

Depending on where you've got safe places to put screw holes in the
chassis, and where the center of balance is, you're still maybe going to
end upneeding a pair of pieces of steel plate and some angle iron bits.
