256 Holes

I have to make 256 holes in an 16x16 array in 3/16" thick hardboard for my BADASS Display project. Any suggestions for getting them perfectly aligned?

@max...well my Tuff Sucker has not broken, so I guess it is tuff...but it certainly does not suck like an Electrolux.  Once it gets the smallest amount of dust in it, it does not suck very well at all (in fact its sucking sucks, if you see what I mean.... :-)   You then have to take the filter out and wash it.  But in the main the Ryobi One+ tools are great.

OK, here are some links:

RotoZip (web site is annoying; looks like a mini-plunge router), circle cutting attachment

Electric cut out tool (similar to some of the RotoZips)

Oscillating Mutli-Tool (I have the cheaper one, and it's been much more useful than I expected)

Electric Body Saw

The size of the chips matters to some

I don't like to make chips when I make holes, so whenever I can I use either a number 5 jr hand punch (depending on punch and die installed, it makes a hole up to 1/32 over 1/4 inch) or a model XX (up to 1/32 over 1/2 inch hold, again depending on punch and die set installed). Harbor Freight has made cheap copies of both but they are sporadically available, the punch and die sets are not interchangable for the XX copy. Thr original models are currently made by Roper-Whitney, the best current maker of Sheet Metal tools including cutters that cut a 90 degree notch (and other angles) with one squeeze. All these tools are meant for sheet metal, usually flat. The XX is my favorite, mostly because I have the punch/die for D-shaped 3/8 hole needed for BNC jacks. Ebay has the basic punch and bsic set with 7 punch and dies, but it is a little tricky getting other than standard fractional round hole-maker punch and die sets. Quote last year for a replacement D-shaped 3/8 set was $90.

Tuff Sucker

@David: ... and even a vacuum cleaner called a "Tuff Sucker"

I do like the name "Tuff Sucker," but don't forget the old adage that goes: "Nothing sucks like an Electrolux" :-)

@TonyTib: Since I don't tend to use power tools a lot, I've been mostly buying corded tools: they give lots of power without having to worry about charging the battery or paying for Lithium batteries.

I'm 100% with you on this -- I don't think I have a single battery-operated tool -- it's not that I don't use the tools, but when I do so I'm in my garage, so power isn;t a problem. I guess that if I was on a building site doing thsi every day, I'd be more tempted to use battery-powered versions.

Last time I used a nibbling tool it had a squeeze handle. Powered now - cool!

There was a time when very small "hole saws", with 2 teeth, were used to manually cut about 1/8 inch diameter islands in copperclad pcb material for breadboarding.  Don't know if they are still available.

Adjustable hole saw

 I think an adjustable hole saw  (aka circle hole cutter) should be included in the discussion

 

And back to my favourite, Lee Valley, for an adjustable drill bit

And the "oops" arbor just caught my eye

@TonyTib....In the old days there was a company called EMCO that used to make the Unimat and Minimat lathes - pretty small, and my friend who had a big one said they were "toys" but they were decent quality and good for small work.  They're no longer made, but you can find second hand ones, they command good prices.  As you say, the chinese stuff has taken over, and some of them are not too bad.

You are right, a scroll saw is a handy thing, especially for unusual shaped holes, as is a jigsaw, and as I do have one of those that was a serious omission.  I've used mine to make neat square holes in wooden cabinets for access to mains and data outlets that would otherwise be hidden.
