I thought about the torch but I am not well versed in it's use. I recon
practice might make it more practical. I am building a grill guard for a
friend of mine for his semi tractor trailer rig... he is tired of having the
deer and elk grace his radiator. I am welding 2.5" DOM as a sleeve in the
web of the beam and running 1.5" schd 80 through the DOM and holding it
there via set screws. The idea is that if he really bends a pipe up he can
pull it out of the DOM and replace it or straighten it. It is a mammoth
project and should come in at around 300 lbs.

I have a 4x7.7 I-beam I need to drill a series of 1 3/8, 2" and 2 1/2"
holes
through the web. What is the most productive means to accomplish this.

What's going through the holes? I would say a flame drill
would be one easy way to do this.

You are aware that a hole like this will weaken the
beam to some degree, right?
