2D Fasteners

Does anyone know where I can buy a small quantity of the 2D Fasteners that hold Elecraft cases together? These are the aluminum blocks with 2 threaded holes on one pair of sides and 1 threaded hole in the other pair of sides.

Is there an alternative name for them? I tried Google and came up with nothing.

73,

Alan. G4GNX

Re: 2D Fasteners

I bet they're proprietary to Elecraft, but I don't know that for sure.
Easy to make if you have a drill press, hacksaw and 4-40 drill and tap.
Hard to make without. If you make them, observe and measure very
carefully. The holes are not centered on the block. They're offset ~1 mm
from centerline. I forget exact dimensions. Be exact.

Re: 2D Fasteners

I've never understood why a three-dimensional object is called "2D".

Presumably because they *fasten* in two dimensions (there are no
threaded holes in the ends of the blocks).

Hi Alan,

We designed these specifically for our products; they are not available commercially.

Please contact sales if you require a small quantity of them.

Alan,

That is a custom design by Elecraft, so I doubt there are alternate sources.
You can order by contacting Elecaft sales ([hidden email]) and ask
for p/n E100078 - 2-D Fastener.

They are only able to connect one plane to another plane. They cannot
connect three planes at one time. Making a 2D connection is what they do.

But they *do* allow you to join two enclosure planes while also supporting a PCB or other hardware. That was the intent of the design. (I invented these in 1998 :)

Re: 2D Fasteners

Perhaps the incorrect wording is being assumed.

3D is 3 Dimensional to most folks.

2D in this particular case is probably better described as 2 Directional (as
in fixing item 1 to item 2).

Thanks Don and everyone else who replied. I had not realised that they are

I've had one possible offer of some spare ones, but if I need more, I'll
contact Elecraft Sales.

Re: 2D Fasteners

I'm glad you see it my way :-)

BTW, a couple of our other club members projects are worth taking a look at.

Also, one of our members reported at last night's meeting that he received his
KPA1500 the day before but didn't have in on the air yet.

Re: 2D Fasteners

In reply to this post by Wes Stewart-2

Wes,

If you are referring to the aluminum angle stock, I used that back in
1960 when constructing a amplifier. I did not think I "invented" it,
and at that time I did not have a drill press, just a hand drill and a
tap, so the holes were not precisely spaced. It worked well, and
complied with the TVI problem of that time (put everything in a shielded
box).

Re: 2D Fasteners

The same principle has been used in woodworking for quite a long time.
My father learned it from his grandfather for cabinet making. I am
currently watching the British '70s television series Connections.
Re-inventing things over the centuries is quite common. The problem
which needs to be solved pushes the imagination of the builder into
crafting similar answers.

Re: 2D Fasteners

In reply to this post by Don Wilhelm

Don,

I've used angle stock on more primitive projects but if you look at the
picture(s) you can see that the flat plates are joined with 3/8" square aluminum
bar stock. I used T6 material for its clean drilling and threading properties.
The flat plates are all 6061-T6 material as well. Everything was laid out on a
granite surface plate with the work held vertically and layout lines scribed
with a vernier height gauge. The holes were matched drilled in the plates and
bar stock. The bar stock was threaded (8-32) and the plates drilled for screw
clearance . But because of the precise layout the parts were still interchangeable.

Everything was power sanded, dipped in a caustic batch to slightly etch the
surface, water rinsed, dipped in an acid bath to remove the smut, rinsed again
and then given a conversion treatment (Alodine). All of the lettering was
engraved and filled with India ink and a drafting pen. All of this was SOP on
the specialized test equipment we built at Hughes back in the day.

The only pieces in these two amplifiers that I didn't fab myself were the two
clamps for the cold ends of the plate lines on the 8877 amp. I did do all of
the silver plating as well.

Re: 2D Fasteners

I think Wayne’s short 2D fasteners are kind of special. Being just long enough for the joint, they allow an adjustment that I’ve used so many times constructing the K transceivers, etc. to fit the panels and boards just so. Also light weight.

I used T6 material for its clean drilling and threading properties. The flat plates are all 6061-T6 material as well. Everything was laid out on a granite surface plate with the work held vertically and layout lines scribed with a vernier height gauge. The holes were matched drilled in the plates and bar stock. The bar stock was threaded (8-32) and the plates drilled for screw clearance . But because of the precise layout the parts were still interchangeable.

I did not think I "invented" it, and at that time I did not have a drill press, just a hand drill and a tap, so the holes were not precisely spaced. It worked well, and complied with the TVI problem of that time (put everything in a shielded box).

Inventing something is a no-brainer. Getting patent protection for it
is something else!
My wife's grandfather had several hundred patents in the paper-handling
industry. At least one was violated by Eastman Kodak with no viable
recourse.!!

Wayne and others

The 2D fasteners - invented, patented or not - they make
for some beautiful cabinets. They are both stylish and
a delight to use.

More good from Elecraft
