K3: machined concentric knobs from Mouser

I received my machined concentric knobs today from Mouser, and as promised,
I would write back to the group with my findings. First of all, the knobs
are incredibly well made and appear to be anodized black. There is a fat,
white, indicator stripe on the barrel. There are also two set screws. The
knobs fit PERFECTLY on the K3 with absolutely no shimming or modification
required. Just take off the old plastic knobs and replace with these.

The knobs themselves are expensive - somewhere in the neighborhood of 13 or
14 dollars per pair, but in my opinion well worth the investment. The outer
diameter and length of the knobs themselves are also a tad larger than the
OEM plastic pieces, making adjustments easier for fat-fingered types.

Anyway, this is the part number again for anyone interested: 506-KN5700B1/4

The only downside to this is now none of the other knobs match, and all feel
"cheap" compared to these Mouser units.

Re: K3: machined concentric knobs from Mouser

Here are two pictures. I left the bottom RF knob off to give you an idea of
how well the larger concentric knob slides onto the encoder shaft. It's
perfect; no looseness or wiggling.

Re: K3: machined concentric knobs from Mouser

The word is inexpensive... not cheap! Those look really nice! I was
just sitting here wondering if there was a knob that would fit over the
shift, width, speed, and pwr knobs. I'm not so sure I'd want to mess w/
them too much though as I'd not want the spacing between them to get too
terribly much smaller. They work well as they are... But that does look
quite good...

Hi John,

The K3's knobs were custom-designed (by me). They match, too :) So
the thought of using knobs from another vendor on a K3 is a bit
painful....

It's true that our knob manufacturer used the wrong material for one
early batch of the dual concentrics. But we caught most of them,
rejected the rest of the stock, and we've been replacing them in the
field as quickly as possible. The correct material is very strong, as
you'd expect.

If anyone feels their K3 knobs are substandard in any way, they can
request new ones at no charge.

I suppose some operators might prefer a full set of machined knobs,
but you can imagine how the cost of K3 would have to increase given
$14 per small knob, and more for the larger ones. Like most other
manufacturers, we've tried to keep our rigs cost-effective, yet still
aesthetically pleasing.

(That said, would you pay $200 for those knobs if we designed them for
you? Just asking....)

Years ago I worked in an injection molding factory. There are multiple parameters that you
have to set on the machine: temperature, pressure, time, cooling, etc. and some of these
have 'profiles' -- they are not simply scalar quantities, but vary over time.

Different materials, sizes and shapes of products, kinds of molds, etc. require different
setups. I'm sure there is a science to it, but I remember it being a black art. If you
didn't do everything right you got all kinds of defects, including parts that seemed OK at
first but later became brittle.

I remember an incident in which our engineer took some sample kitchen faucets that we'd
made to show them to a distributor. When he demonstrated the quick smooth action of one of
the valves...snap. The stem broke off in his hand. "Hmm, that never happened before," he
said, and turned the other valve. Snap.

They would have to be_ alot_ nicer looking than the stock K3 knobs.
I really like the stock knobs anyway.

Re: K3: machined concentric knobs from Mouser

I sure wouldn't pay $200 for machined aluminum knobs. I could make my
own if I wanted to, but don't see any need for it.

It's funny though, sometimes I think the K3 should have some kind of
hardshell cover for the front panel. Then you could transport it
without having to worry about banging up the fragile controls and LCD.
Not that I transport the rig much... I guess I just think it would be
cool to have a snap-on or hinged panel cover.

Re: K3: machined concentric knobs from Mouser

In reply to this post by wayne burdick

(Sorry for the duplicate reply; email problems...)

Wayne,

My intentions certainly weren't to insult the designers. However, there's
only so much that can be done quality-wise at a certain price point - I
understand that. It's true that Elecraft has stepped up to the plate and
replaced all broken knobs which I commend. The problem in my case however,
is that both sets of replacement knobs which I paid for and received had
off-centered holes. They didn't crack this time around, but because of the
off-centered holes, were incredibly difficult to adjust. The top knob would
rub against the bottom no matter what because of the cam effect.

Anyway, to answer your question... if Elecraft designed and released a
complete set of machined aluminum knobs and sold it as an upgrade for $200,
I'd order it. In my opinion, the current plastic knobs are the weak-point
in an otherwise perfect package.

Re: K3: machined concentric knobs from Mouser

Not me. I like the ones that are on there now and if I have trouble because
of being part of the "bad batch" I know I will be taken care of and that
will be the end of it. I would NOT pay $200 for replacement knobs that I do
not think look right on the K3. It looks great NOW.

Re: K3: machined concentric knobs from Mouser

In reply to this post by Bill K9YEQ

That was exactly my thought! Last year, I looked at the nice big heavy tuning knob
on my IC746 and thought how nice it would be to have that on my K3...and then I
realized that the rig would start to get heavier and heavier if you started replacing
the current knobs. Might not be much on the scale, but like dB on EME, they all add
up! Having carried this K3 with me to E51, I appreciate keeping it as light weight
as possible. I will stay with the little plastic knobs until they get smashed ;-)

Folks (and especially Wayne),

we must be very happy transceiver owners that we start
discussing about the quality and design of the knobs of our rig.
It shows that the K3 is a nearly perfect machine - except the
too slow maximum keyer speed, of course ;-)

Exactly Martin. I love my K3 in just about every respect.

I only have two gripes: the knobs and the DSP NR.

Other than that, tickle me pink.

Not that I transport the rig much... I guess I just think it would be

I tried to get one made at my local TAP Plastics (El Cerrito), but the
fellow there didn't seem to be able to get it the right size, even with
my leaving the K3 with him.

I'd like to have such an item.
One of the few advantages of some of the Japanese-manufactured rigs is
that the front panel is removable, so the heavy part can be separated
from the fragile part.

We solved that by not making a heavy part in the K3 :-)

I had a foam shop fabricate a custom die set for punching out foam
protectors for both the front and rear panels of the K3. The closed-cell
foam is then glued to a thin sheet of PVC which protects the foam and
distributes any shock applied to the front or rear panel. The foam cut-outs
clear the knobs and connectors, contacting the sheet metal portion of the
panels. See http://www.w0yk.com/images/k3_foam.jpg. If there is enough
interest, I might consider having another run of them made up. Price would
be $15 plus shipping.
