I spent the day getting a used greenhouse home. I'm plumb wore out right
now. So, I'm a dreaming on the re-construction. I'll build it on skids so I
can drag it to new ground every year.

To do this, I'll need two runs of square tubing on each side. Fifty spots on
each side to drill a 1.9" hole for a total of 200 holes. Then weld a
vertical sleeve at each hole. The base on the sides will look just like a
ladder laying down.

Anyway, what would you use to drill 200 1.9" holes in 2-1/4 (if made) or
2-1/2 square tubing. I have a radial arm drill press. I know I'd go through
SEVERAL 1-7/8" regular hole saws. There must be a better option.

"Lenin called them "useful idiots," those people living in
liberal democracies who by giving moral and material support
to a totalitarian ideology in effect were braiding the rope that
would hang them. Why people who enjoyed freedom and prosperity worked
passionately to destroy both is a fascinating question, one still with us
today. Now the useful idiots can be found in the chorus of appeasement,
reflexive anti-Americanism, and sentimental idealism trying to inhibit
the necessary responses to another freedom-hating ideology, radical Islam"
