Been there, done that, result is UGLY but it does work. Dampen the rod
first.

I need to cut a notch in the end of sched 40 3.5 inch pipe to allow 2
inch
pipe to pass through it. Available tools are reciprocating saw,
drill press
with bits up to 1 inch and bimetal hole saws, and cutting torch. What's
the best way to do it? The notch needs to be snug because the 2 inch
pipe
will be welded to the 3.5 inch pipe using stick welding.

Since you are going to weld a pipe back in, I'd use the cutting torch.
If your good with the torch the somewhat jagged hole will be welded
up. Much less effort than trying to secure in a drill press. Also you
didn't mention how long the 3.5" pipe is. Might be tough to wrestle
into position on a drill press.

I'd like to see him cut that hole with the stick welder G
Gas torch wasn't in the list of available tools.
