Could I get some advice on working stainless steel and its properties?
I want to work sheet and plate to about 1/8 thickness and have found
this stuff very tough in the past. How would one drill and cut it
with good results in a homebuilders shop? What types of saw blades
and drills work best? I do not own a metal bandsaw yet but it is
probably going to happen. Can this stuff be cut with a hacksaw?

Also which stainless is good for fittings and such?
Thanks from Canada

The most important thing to learn about stainless is that it work hardens
instantly. Let's say that you are drilling a 1/8" hole with a typical 1/4"
capacity electric drill motor. If you pull the trigger, then set the bit in
the centerpuch mark and start to apply pressure, you're all done for the
day, pal.

You *must* use a variable speed drill, place the bit in the centerpunch
mark, apply *lots* of pressure, and then *slowly* start the bit turning. It
must cut into the metal with every turn. If you "skid" the bit over the
metal - even once - it will work harden to what seems to be the consistancy
of a diamond.

Same story with a saw.

You will probably get a lot of conflicting information about this and
arguments about which alloy of stainless will act this way and which won't.
But if you follow this procedure you won't go far wrong with any alloy
stamped CRS (Corrosion Resistant Steel).
