Default Drilling 500 holes in mild steel

Make sure you get the aluminum cased version of the 90, not the plastic
one. I have one of each, the plastic one has gears nibbled by beavers
and bearings mounted in mush.

I have to drill 500 holes with a #1 drill (0.2280 dia.) in mild steel
in cramped quarters on a truck. I will have to drill these holes
sitting and reaching out nearly arms length in front of me. It is very
tiresome to put the proper pressure on the drill.

I would like suggestions:

1. The best way to accurately position the drill (some kind of punch
to dimple the steel?)

2. A way to put the pressure on the drill without the stress of
applying all the pressure myself.



Not sure if you can, but using a simple lever to apply pressure works
very well. We have to do this at work in cramped situations. I'd
highly recommend a good drill with a good chuck as you can actually
apply a *lot* of force. I'd recommend square metal tube or wood as
it's light and won't slip off the drill like round will.



You might look at one of the 90-degree attachments that are available.
The one I have is a $10 HF variety, but gives you about 6 inches more
reach (no comment) and also a nice flat surface opposite the chuck
against which to apply Robin's lever.
