Drilling straight holes without drill press


How can I drill a straight hole without a drill press? Does Harbor Freight sell an accessory? The holes will be 3 1/2 in deep. One option I was thinking of was having a friend drill holes in a 2x4 with his drill press and then using that as a guide. Unfortunately, I can't bring the wooden posts to his house for drilling.

Lay a mirror down on the surface you are drilling, right next to the bit. It will help keep the bit perfectly straight. Works best if you can get hold of a plastic mirror, and drill a hole right in the center....... drill through that hole.

The Kreg kit is nice as well. That is the one that I use often. Drill press would be less time consuming, however I just don't have the space.

As mentioned you can buy drilling jigs but your 2x4 idea sounds promising and cheap. What diameter are these holes though?

Curious but lost you on this. Can you explain further?

The holes are for 3/8" carriage bolts. The will secure a board to the top of the posts. The canopy needs to be disassembled and reassembled multiple times, so I want the holes to be the same on both sides.

This is why I wish all drills had integrated bubble levels like my dad's old Craftsman does.

Carrage bolts do not need a tight hole, just drill the hole over sized.

Then layout and drill in from both sides instead of drilling all the way through.

+1 Slightly oversized is good. May require blunt force persuasion.

The 2x4 with a hole drilled by friend should be OK. You can take a 2x4 and cut a notch in it, gives you a 2 sided guide. I suppose you could even clamp 2 different 2x4 pieces on in a L shape.
