Does anyone know where I can locate a genuine tool for severing the
traces on veroboard? I know I can make do with a drill bit, but that
puts a tapered hole in the resin board underneath.
One thing that's cheaper in NZ is, strangely enough, veroboard. The
few pieces I found in the States were priced much higher than
protoboards used to be at Rat Shack (when you could find them). I
occasionally run into a project from a UK experimenter, and have
wanted to do their designs without doing 100% point-to-point. I'll
probably bring home a couple of panels so I have a chance to do that
(for my own stuff, I'll probably always do point-to-point).

another one myself although I've tended to use 'blob' board more often
these days.

since change of owners a couple of years back.

RS? I've heard it referenced on the list... is that the name of a
particular brand of shop?

Not yet, but good guess... I was at a different place, forget the
name, but for some reason the address stuck - 145 Manchester St
(stuck, I suspect, because someone else here asked me if I went to
Smith's)

Metalworking tool catalogs should list counterbore drills -- that
should serve if you can't find the original tool. A counterbore is a
device vaguely like a drill, except the tip "angle" is 180 degrees,
and there's a pin in the middle to guide it. You use it to
counterbore holes to take screws that have flat bottoms, not conical
ones.

Sounds like the one I used to have - I always thought it was a genuine
VERO tool but maybe not.

Why not just get a end mill as used in milling machines? They come in a

And the last time you (successfully) tried to cut a 3/32 flat spot into
fibreglass PC board using a hand-drill - or even a Dremel tool? with an
itty-bitty end-mill??? Unless of course you have the mill to go with the
cutter - then you can clamp it down and just take a fine cut. 20 minutes
later, voila! all done!
The thing about the Veroboard tools is that they have a central locating
pin that fits into the hole, around which you want to cut an insulating
ring. And it's that centering pin that makes it easy... without it, well
- I hope you have spare board stock on hand. ;}
Been there; done that; still have the bloody t-shirt.

20 minutes! I could chip out a piece of flint and cut with that in less
than 20 minutes! It takes me longer to walk out to the shop than it does to
cut it. Clamping, installing the end mill, cutting, removing the CCA and
cleaning out the chips takes WELL under two minutes.

Good for Veroboard. If that's what you want THEN GO BUY IT! But Ethan
asked for a substitute and they do not make counterbores with guide pins
small enough to fit into a wire hole on a circuit board.

That why I use a milling machine! In case you've nver seen one, you
CLAMP the work in place and then move the table (with the attached work
piece) to the correct position. I suggest you go find a book on milling
machines and read up on them. It's a very usefull machine.

AHH! So *that's* what I've been doing wrong these last 40 years or so -
dang - shoulda read the Bridgeport manual before I went to All That
Trouble. I kinda thought I shouldn't have to use the travelling crane and
bosn's chair every time I wanted to make a little piece for something.
Hey! I bet I can unbolt the LeBlond spindle from the shop wall and
it'll stop flinging parts all over the place when I try and turn
something...
This List is *such* a great resource...

PS: I don't think you got the fact that I was **kidding** Joe - ya'll need

New subject: 7 Track tape drives?

RD-358(V), RD-358A(V)/UYK Magnetic Tape Subsystems (MTSs)
The MTSs are medium speed devices providing a means for large capacity
auxiliary storage of computer data on magnetic tape. An MTS consists of a
Control Unit and a Magnetic Tape Transport (MTT). The control unit contains
the logical functions required for controlling the MTT and accommodating the
requirements of the external data processing system. The MTS is used by the
C2P for extracting data, reading JTIDS information from tape, and transcribing
files to the Embedded Memory Subsystem (EMS).
The RD-358(V)/UYK has two tape drives which have seven recording tracks.
These units are found on CV/CVN platforms.
The RD-358A/UYK has four tape drives, two with nine recording tracks and two
with seven recording tracks. These units are found on CG, DDG, and LHA
platforms. The C2P controls access to the specific recorded media for JTIDS.
A ship requiring "nine track" tapes cannot subsitute the use of "seven
track"
tapes due to C2P programing.
