Hi guys. I need to re-drill some bridge posts and other things. I want to be sure I have the hole going in at 90 degrees. Is there a guide or jig of sorts that I can use with my hand drill? Thanks.

I don't know what it's called, whether I can describe it adequately, or if it was "available only through this special TV offer," but here goes: Somebody made a rig that was pretty much just a stable base into which you placed your electric drill. The base had four contact points ("feet") that stood flat on the surface being drilled, and the drill was pushed downward as the bit made the hole. At least two of the sides (opposite each other) were arced between the feet so that it could fit over a piece of pipe and keep the point of the bit from skidding off the curvature of the pipe. I haven't seen the ads for awhile now, but if I knew what it was called, I might be able to point you to a place to buy one. Or I'll buy one, and you can borrow mine.  About the only other thing I can think of is something like these www.ares-server.com/Ares/Ares.asp?MerchantID=RET01229&Action=Catalog&Type=Product&ID=60714. They'd at least work to get it lined up before starting to drill, and maybe while the bit was turning. (When the top of the angle plate started to get in the way of the drill chuck, the hole might be as deep as you needed, or deep enough that the bit couldn't go too far askew.) |

I narrowed it down by making "hand drill guide" an exact phrase, and got one old link that mentioned a "Wolfcraft 4525." Searching with that as a phrase got much better results. Not the one I mentioned earlier, but close enough. It looks kinda neat, and isn't too expensive (IMO). |

I made one (on a drill press) using a 1" thick block of aluminum drilled with many holes of different diameters. You dont need all holes, just enough for pilot bits.

hondro, You mean you want one of these babies:  Available everywhere that you can think of. Sears has one at $27, the pictured on above is from Rockler (but at $32), and I'm sure there are others out there that beat these prices. Strangely, Harbor Freight does not have one of these.  HTH sumgai |

Ive got a device like this that I bought recently in a hardware chain (Bunnings - for any Aussies watching), for $15. It mounts a standard electric hand drill, and is made in China like all good cheap things. It has a proper lever-arm handle to pull the drill down in a controlled way, a base that bolts to a bench, and adjustable stops to set height and depth. It is just the thing for small precision metal and wood jobs. My favorite tool right now.
