Another way to do this on the cheap is to use two stainless steel hose
clamps, the kind used to clamp flex hose on auto radiators.
First cut a short length of 2x4 stud, say 4-6 inches long. Drill a 1/4
inch(or slightly larger) hole through the center section of the four
inch wide side of the board.
This will allow for a 1/4-20 screw(flat head to allow for flush fit on
the bottom side of board.) of 1-3/4 to 2" length for the direct
mounting of the camera or better yet a tripod head.
The whole assembley can then be clamped snugly to the tube railing
with the hose clamps.( The clamps can be loosened up to the point
where the strap comes out of the worm gear collar allowing you to slip
it around the tube railing. Then simply push the end of the clamp
strap back into the collar and tighten until it threads back in.)
I keep one of these rigs handy for stationary camera that are
generally used for wide or area shots.
Most hose clamps are hex heads as well as slotted.
This allows for the use of a nut driver instead of a slotted
screwdriver.
The nut driver won't slip and is much easier to use vs. your typical
screwdriver. (most clamps use either 5/16 or 3/8 nut drivers.)
For 3-1/2 inch railing you'll most likely need at least a 5 inch
clamp.
Also if your worried about the steel clamp scratching the railing
simply use a small piece of flat rubber sheeting on the bottom side of
the railing inbetween the strap and the rail.( On my rig I coated the
bottom of the 2x4 block with silicone. Gives a better grip and enough
padding to avoid mars on wood or metal.)
Mine cost me around 3 bucks or so, can't get much cheaper than that,
and it's reusable.
