Mouser carrries them as well.....$250 or so. Expensive unless your doing alot of panels. Might call around to the local metal fab shops and see if they have one, and what they would charge to punch for you {Quote hidden}>From: "Michael J.

As you can see, they are expensive, but that's the going price for good punches if you plan on punching for production work. If you are wanting to punch a few holes for hobby projects, you can use a template to scribe out the "D" and the mounting holes, drill the inside as close to the scribe marks and finish it off with small rat tail and flat files. The "D" doesn't have to be perfect. The connector will hide a lot of slop if it ends up to be more of a rectangle rather than the tapered "D". You'd think they would come up with a round hole mount connector for the Sub D's but I guess it's not worth the R&D effort and limited manufacture of such.

Judging by the UK price of the Proxxon machines, it would probably be possible to by the milling machine for less than the US price of a single punch. Not only that but you then end up with a universal machine capable of a lot more. -- http://www.piclist.com hint: To leave the PICList piclist-unsubscribe-requestSTOPspamspam_OUTmitvma.mit.edu

I have the Deltron type and they work just fine on plastic, Al and mild steel. Broke one trying to modify a stainless-steel case once. Pretty impressive noise when it snapped. Consider what your time is worth to you. If you are doing things on your own dime then fooling around with drills and Dremmels might be OK but with the Deltron type I can have a hole punched in about 10 minutes or less (assuming I can find my drill bits to make the pilot holes). If you value shop time as low as $30 you can pay for a punch after just a few uses versus drilling and filing. http://www.mouser.com/catalog/617/1179.pdf You might be able to find the Deltron punches through other sources too.

I can easily drill and file a hole in 10 minutes - as suggested you do a quick autocad or whatver drawing - print it out on a sticky label or use some spray mount, drill the centres of the holes and use a fret saw with a fine blade to 'join the dots' a quick bit of neatening up with a file and you're away. I have even used a power jigsaw/ scroll saw with a fine blade to do the same thing so long as youre not trying to do it on stainless - this is particularly good for large things like fan cut outs as it takes longer to take the blade out and put it through one of the holes you have drilled than on a hand saw. It owuld probaly be quicker with a milling machine, but i don't have one sadly.

Locate (my punch has a template piece for locating the pilot holes), drill (3 holes or single depending on punch), assemble punch, turn wrench. 4 steps. I didn't account for assembling tools in either case since it would probably be about the same number of tools or steps. For simple shapes like holes, squares and rectangles a drill and file may be quicker but to get a nice neat D-sub hole, but especially for inside mounting a punch is pretty slick. For outside mounting where the flange of the connector covers any ugly maybe cutting and filing is OK. On the other hand, I have access to some small machine shops that can do custom steel and aluminum cases at reasonable rates. For a personal project I wouldn't use them but for client financed jobs it is well worth it to pay somebody else to do the mechanical prep while I concentrate on circuits and hardware. Just gotta be sure to coordinate at the start so we don't end up with a round hole and a square peg!
