I made a rear rail for my magnetic chuck, and side-ground it:
The rail is designed to slide down out of position, and has a groove so that the inside corner is free and there is a drain path for grit and swarf:
I made this out of construction (low carbon) steel, but needed to be careful to provide "mounting pads" which are fairly small so that they don't short out the magnetic field of the magnet poles. The next time I make a rail like this, I want to make it from some kind of metal that is non-magnetic, so I can make contact all along the chuck.
Could someone recommend a type of stainless that is (1 ) non-magnetic (2) easy to machine (3) fairly inexpensive (4) available in ground stock of the right general size, say 8 x 30mm?
Cheers,
Bruce
