Drill accessory to hold it perpendicular to hole surface

I'm looking for something which will eliminate the need for a drill press. I've used bushings inserted into scrap wood and I've tried the jig from home depot which costs forty bucks and which can be described with a word which sounds very similar to 'trap' and I was hoping that Festool would have created something useful. The Festool solution appears to be to use a router, but I find I can't really do that in most cases.
 
WHOA! I could get a killer drill press for the price of those Mafell Drilling Stations Christian!

I think his point was something that was not as expensive as a drill press.

I agree those protool and Mafell drill stands look good. They better for the kind of money being asked. But I was really hoping Festool had a comparable product. It would cost crazy money too but it would integrate well with the cordless drills and be portable.

That Rockler system looks good, and even great for the price.

The Rockler (shown above) looks similar to a General jig I've had for some time.  Used most of the parts to create this Confirmat jig.

The Rockler should work for you, but you might want a more stable platform.  I don't like that handle's shape and placement much.

Ned I had that jig and I did not like it at all(It's squirly). Like you said the handle and platform are not quite right to prevent movement when the bit first goes in, the bit walks. At least that is the problem with the Rockler version.

The little plastic device works better if you only need a perpendicular hole and not an angled hole.

I like that jig a lot. But please allow me to suggest a couple of revisions based on experience. And by experience I mean an injury.

1. When you have a choice it is probably safer to be pushing a power tool away from your body. With the shoulder on the far side of the bit from the handle you are drawing the jig towards your body to position the jig.

2.  I think I'd replace the narrow shoulder with something about two inches high. That way the jig would naturally 'lock' itself perpendicular to the edge.

3.  And I'd make the two inch high thing which replaces the shoulder both adjustable and removable using knobs and bolts. Your description indicates that you have to reassemble the drill stand to drill on non-edge surfaces. But I think the really terrific thing about your jig is the dust collection. I'd want that feature every single time I used the jig!

But the jig you designed gives exactly the functionality I am looking for. Thanks very much for pointing me towards it.

[various good observations/suggestions about my Confirmat jig.]

It's due for a redesign, and you've listed most of the reasons.  I think you'll like the next generation.

BTW, welcome to FOG.

    What would be great is a Fast Fix drill guide chuck! Something along the lines of the Triton http://www.amazon.com/exec/obidos/ASIN/B00092CPOI/ref=nosim/toolsdeals1-20

Seth, that's a great idea.  I'm embarrassed I didn't think of it already.  ;)

I don't have a C12 in front of me, and I'm running on a few minutes impression of the C12 in Henderson, but...

The right angle and eccentric chucks attach to a ring that allows multiple attachment positions, but does not allow the chuck body to rotate once it's attached.

I think the Centrotec chuck attaches just to the drill arbor, not to the attachment ring.

So-- perhaps a drill guide could be attached to the ring, while still clearing the Centrotec chuck.    Even if the Centrotec chuck won't clear something attached at the ring, the central hole in the C12's arbor could be used to fit an extension chuck for use with the drill guide.

If I'm right so far, we've got a great deal of freedom to design the guide itself.

The drill guide would work on any FastFix drill, not just the C12.

If Festool isn't interested in this idea, it's a perfect example of what Lee Valley/Veritas could do.
