Alright all you geniuses.

I've got Calmini Belly Armor on the Gnewt.  I have to remove it to change the oil, and other fluids.  I want to drill holes in it so I DON'T have to remove it to change the fluids.  I don't have a torch, or a grinder.

What's the easiest way to punch some big holes in that steel, say 1.5 to 2 inches in diameter, so I don't have to drop the armor?  This is 3/16" plate steel.

I got carbide tipped hole saws, but a Greenlee
hole punch is the cleanest way, if it can do that
thick of plate. The Greenlee is used by Electricians
to punch holes in electric service boxes to add
conduits, if you have an Electrician friend, you
might be able to borrow or have them help you
punch holes.

Yeah, I know about greenlee punches, but didn't know if they could handle 3/16" steel.

I know a shop here in town that has a
punch machine that can do holes in up
to 1/2" plate, it's really cool to watch,
perfect holes just look sooooo good.

Mark your locations, pull it off and take it by a local machine shop. Something that simple for them should be cheap enough.

I was going to just do it with my air cutting tool and make the hole square....

mark it and use a hole saw if you want to do it cheaply. a good hole saw and 1/2" drill will handle 3/16" with little effort

When you say "good hole saw", what is it made of, and where do I get it?  Is it a special material to cut steel?

With the high location of the trackick's oil plug - and the protection provided by the skid plates, I've been considering getting a fumoto valve (http://www.fumotovalve.com).  It would at least ease oil changes.

PS:  Bobzooki - I'm the guy who went on the snow run with you in the beginning of March.  I'm looking forward towards some more trips up in the hills.

Craig?  Is that you?  Man this is going to be one hard-wheeling summer!  I have a zillion runs I want to do, including one over Medano Pass, into the back side of the Sand Dunes.

Craig?  Is that you?

Yep, it's me!  I'm not sure how much wheeling I'll be able to do, but hopefully a few weekend trips.  And at least one week long trip around Gunnison - I'll be the "chuck wagon" for rest of the people on the trip.

I have used the steel cutting hole saws made by dewalt on a 1/2" drill and cut (7-8) 1.75 holes through 3/16" before any sign's of wear

You could scribe a circle then drill all arrond the outside with a small drill, knock out the centre with a cold chisel and then file it smooth.Not the easiest way to do things but it's the cheapest.

Hah, so I got the 2" bi-metal hole saw (BluMole) at Home Depot - damned thing lost its teeth before I was half way through.  I drilled small holes around it, and it still wouldn't finish the cut, so I finally put a metal blade in my saber saw and finished the cut.  What a pain in the ass.
