Krw can't do grammar, or rational argument. One brags about being a member of an "elite" group. Individuals can't be "elite" on their own. Since you get to be a Life Member by doing nothing more than being older than 65 and member of the IEEE for long enough, life members are no more an elite than the rest of the IEEE.

Since the IEEE does vet applications for membership, it might qualify as an "elite" group. Since they accepted me - when I didn't have any formal training in electronics - they aren't all that elitist.

http://sites.ieee.org/nsw/committe/

I'm the treasurer for the local - New South Wales - branch of the IEEE.

With electronic banking it's not an onerous job, but the IEEE does make it more time-consuming by insisting that I report every transaction on their Netsuite program, throwing in .pdf images of every last claim form and receipt.

At the moment Netsuite and our bank agree about the amount of money we've got, but it took a while to get them reconciled.

First of all, I had to give soe thought to this because the way you worded it, it was possible you just did not want it to slide off. I see now that you are talking about it walking off in the hands of some nfarious person.

First and foremost remember that you can never stop a thief. You slow him down to the point where he thingks he is likely to get caught.

The cable idea isn't bad, but bolt cutters are fast and practically silent. Make them use POWER TOOLS !

I just looked up your meter, I am familiar with the scope. I would take them apart and get bolts, or threaded rod and first connect them together. Open the cases, screw them together and have a threaded rod hangoing out the bottom of the scope. Make a wedge, wood would be fine because different blades are used to cut wood than metal.

Ont the BOTTOM of the bendh where you will attach your stuff, attach a piece of wood and drill partly through it big enough to screw on the nuts. Make it so you MUST use a socket wrench to tighten. Then once it is all attached, take one of those littl buzzbox arcd welders and tack the nuts to the threaded rod. Of course inside the scope you either did that or double nutted it.

When you get this whole ting together, either graing part of the heads off the screws in the scope and meter, or fill them with epoxy glue. I would use BIG washers or maybe even a steel plate in case someone is really strong and can pull the nut right through the sheetmetal. Alot of people are strong enough to do that.

Speaking of that meter (which should be attached to the top of the scope), it is now "Keysight" ? Hmm.

If you just use one threaded rod, you should be able to swivel the unit. The nut needs to be unaccesible, the rod need not be tight necessarily. There are probably ways that can allow you to move them as well, but add to the complexity of the solution.

The wood wedge should be solid, anything else they can break and then access the threaded rod with bolt cutters. A small piece of 4X4 should do it, but you will have to saw it down. you might need to use a table saw if you don't have oe. Maing this wedge out of steel would be nice, but is alot easier said than done. to say the least. Plus at the size you need, it would be pretty heavy.

Another thing, that piece of wood you attach to the bottom of the bench, of course you screw it, BUT ALSO GLUE IT.

I have known some thieves in my time and heard some pretty cool stories. sometimes they wanted me to beat an alarm system but I didn't do it. Well, if it's like govenrment of big business I might consider it realy. But stealig someone's tools is dispicable.

You won't be able to afford a laser scintering (metal) 3D printer. You are talking a million dollars (maybe less for a smaller one though). Plastic ones are 3K or less for cheap ones. You cannot mix metal with plastic. You can make them separate of course.

If you want a nut in the plastic part, you can make a slot that allows you
to slide the nut in from the side. That would be the easiest way to do it.
If you truly want the nut embedded, I suppose you could make the build in
two parts, with a pause in between, where you drop the nut into a
hexagonal cavity. Then, the 2nd part of the build would cover over the nut.

Jon

You would have to be careful, though, that the extruder head doesn't hit
the nut as it travels. You would have to have the opening just about
closed before you added the metal part.

You may be able to do well enough by putting the nut on the starting board
(what do they _call_ it?) and building around it, if you're precise enough.

Or build the knob up with a hexagonal cavity, then epoxy the nut in.

One way or another, the metal part will need to be machined or printed
separately.

I'm not familiar enough with the printers to know how they actually build a

part (the "starting board" is called a "build table"). How close to the

table and previously deposited layers does the extruder nozzle have to be?

Would that distance negate the ability to "print" around another object? I

guess that would be the critical factor.

I think the nozzle is nearly touching the part so anything higher than the ~0.1mm layer thickness would interfer

https://www.youtube.com/watch?v=8j8nMSz32eM&t=4m35s

A new question just came to me... Can a printer build upon a previously

finished part? IOW, can I build half of a part, imbed a metal part inside a

cavity, then put the part back on the table and have the printer build the

rest of the part on top of it?

I don't see why not, as long as you keep everything aligned

Yes, and if the logic "it's shaped like the thing, it must be the thing"
works for you, then you're home free.
There's a lot more to manufacturing a successful product than getting a
bunch of pieces made out of random materials that are more or less the
right shape.

So it has been done. I can't imagine why someone would use random materials.

I'm not familiar enough with the printers to know how they actually build a
part (the "starting board" is called a "build table"). How close to the
table and previously deposited layers does the extruder nozzle have to be?
Would that distance negate the ability to "print" around another object? I
guess that would be the critical factor.

A new question just came to me... Can a printer build upon a previously
finished part? IOW, can I build half of a part, imbed a metal part inside a
cavity, then put the part back on the table and have the printer build the
rest of the part on top of it?

Maybe I should be asking these questions to the 3D printer marketers?
Anyway, thanks for the suggestions,

Dave M

What I'd like to see is a system of "manufacturing on demand",
especially if were possible to improve on the item being replaced. For
example...
I have two classic Sony radios, the TFM-825 and TFM-117WB, whose
paper-cone speakers were okay-sounding 50 years ago, but would sound a
lot better with plastic or plastic-doped cones. Wouldn't it be nice if
I could order a "modern" version for $10 or $20? (Ditto for the classic
KLH full-range driver.)
This is difficult, though not impossible. The problem isn't //making//
the speaker so much as it is //analyzing// existing samples so the
printer can duplicate the frame, the cone, etc. The cost for a single
copy would be beyond unreasonable.

I cant imagine it being too expensive to rotate the sample while
scanning it with a laser to build up a 3d file of it. Has it been done?

Yes, and if the logic "it's shaped like the thing, it must be the thing"
works for you, then you're home free.

There's a lot more to manufacturing a successful product than getting a
bunch of pieces made out of random materials that are more or less the
right shape.
