Default Accepting ones limitations

I just spent a couple of hours in the workshop progressing one of my projects and became disolusioned when after drilling some holes in a case, i realised they didn't line up as i had hoped so had to file the holes a little, i was annoyed with myself as i expected better results, then i thought the way large companies do there metal bashing is machines, i am sitting at the bench drilling holes with one hand whilst holding the case in the other, now i'm wondering if it makes sense to buy a drill press with the relevent clamps or just accept i am not going to achieve professional results with my current methods and file (botch) it till it fits

Neil.

haha, sorry to laugh but I wish I had a nickel for every project I'd started only to have it end in the same frustration as you mention.

A few years ago I bought a relatively cheap drill press with adjustable table and center clamp. While It's no great setup by any measure, I am now finally able with a bit of care to drill more than one hole in a straight line on metal.

I thoroughly enjoy working with metal and I only wish I had the $$ to buy a great setup, but in the meantime this setup from Grizzly works pretty well!

Or learn to build jigs.

I used to watch Norm on the New Yankee Workshop - or whatever it was called - on public TV. A master carpenter. WHen he needed to make something that matched something else he often created a jig. Nail or screw a cleat to a piece of plywood, or whatever, and bolt that to the bench top. Or clamp the work directly to the bench with large C-clamps or those bar clamps carpenters use. I am looking at some bar clamp coupons from Harbor Freight at the moment, $1.99 each with coupon. The idea of a jig is it makes a surface with blocks so you can shove the work piece into it and it will be in precise position. A clamp holds it there.

WHen I make certain panels, I sometimes make a template first and use that as a drill guide.

Neil, welcome to DIY. If I had a nickel for every...well you know the story.

The real thing you will learn in the long run is to include processes that eliminate the potentials of what you speak. It may not make sense now but as you wander through this, you will look back and say "man what was I thinking?"

It doesn't come easy. I went from drilling and screwing, to biscuits and clamps to cleats and brad nails before I realized how difficult I had made things in the past.

Don't fret - thanks for sharing your misery, it's temporary

1. drill a hole of the desired size in a piece of scrap 1x3 or whatever you have.
2. carefully align this over the center of the marked hole location on your work piece.
3. clamp the 1x3 and work piece to the work bench, with another piece of sacrificial scrap underneath (hard wood works better than soft for both parts of this jig).
4. drill through the pre-made hole in the 1x3, through the work piece, and into the sacrifical piece under it.
You can make a perfectly round, perfectly centered, sharp edged hole, every single time with this technique. It doesn't matter if you are drilling sheet metal that is hard (steel), soft (aluminum), thick or thin, this just works.

Metal works drive me mad, too. So I quit building metal cases for amps, I use wood instead

But again, I'm not good at wood works, either. So I quit building boxed speakers. ...:LOL:...

If drilling holes to bolt something together with M4 for example, I often pre-empt the problem by drilling them all at 4.2mm to allow a bit of 'adjustment'! I know that it's possible to make a jig for every situation that guarantees a perfect result, but I haven't the patience. Gradually, over the years, I think my ability to get the centre-punch in the right place and then to drill the holes reasonably accurately has improved. I do usually use a drill press, though.
