IRON165 by Smith + Rune
After almost a year in research and development, we
are excited to present the
IRON165 by Smith + Rune. Rather than
drawing inspiration from things outside our community, we
focused on the incredible designs the community itself has
created over the years. The IRON165 aims to be a
distillation of these positive innovations, included in one
premium board.

Vendors, Quantities, and Group Buy Date
Standard Edition
We’re very
proud to announce we’ve partnered up with
CannonKeys in the US,
MyKeyboard in the EU, and
ILUMKB in the AP/China market to handle all
sales of the Iron165 SE.
What this hopefully means, and
why we’re so excited to work with these amazing stores, is
that we should be able to offer not only a smoother buying
experience, but also a higher quantity of boards than we
initially thought possible.
USA - CannonKeys - Up to 100 boards
EU - MyKeyboard
- Up to 50 boards
AP - ILUMKB - Up to 50
boards
Founder’s Edition
The Iron165
FE will be limited to 26 serialized units, never to be made
again. We will be handling the group buy for these directly.
There will be a public raffle for 10 total group buy
spots.

Keyboard plate FEA analysis was wanted to measure deflection
and try to achieve a uniform plate deflection distribution
across the keyboard. This concept has been done before with
the Omega60 talking about mounting points. One of the first
criticisms was that without a PCB and switch the study was
worthless. I started out by modeling a small sample before
moving to a full size plate. I constructed a small plate
made of brass, switch made of POM, and PCB made of resin
injected plastic.
I wanted to see the difference in displacement just a
plate and a fully modeled with PCB, switches and Plate. With
modeling of the entire system, there are two options in
consideration:
Fully bonded - Solidworks treats the
model as though it was fully welded together at every
contact point.
No Penetration - Materials wont move
through each other but can move independently from other
models.
I estimated typing force to be around 2N max on
each key as I measured my repeated tapping on a scale at
200g as the hardest I would ever really type (and I like to
bottom out).
Next is the fully bonded model with plate and
switches. Again a 2N force is applied to the top of the
switch model with fixtures mounted at the four screw
holes.
Lastly is the most realistic model the no
penetration. Same force and Fixture as above. Notice how the
displacement doesnt flow as uniformily through the switches
vs the fully bonded model above. You’ll also see the
displacement pattern is more similiar to that of just the
plate.
If you compare the displacement results we conclude
that just a plate can be used to model displacement without
the extra PCB and switch modeling effort. The displacement
of the plate model is approx 35% more than the plate with
stiffness of PCB and Switches added to it.
Since each
switch has to be setup and run individually I concentrated
on making just the alphas as consistent as possible. This is
still a work in progress, but here are the initial
results.
This was the stock designed plate mounted with
gaskets. Numbers in each switch represent the maximum
deflection in millimeters for a 2N force:
Adding in relief cuts we can try to make the lower
deflecting keys increase to the same deflection of the
higher deflecting keys. This resulted in a decrease in
standard deviation of 25% and a decrease in range by 35%.

FAQ
New studio? New board? Why should we trust you?
While this is a first in the keyboard community for
us, we are proud of the team weve put together. Combined, we
bring ten years mechanical engineering experience and five
years of supply-chain management for small-batch, boutique
products in other industries.
Smith + Rune is grounded
in basic engineering principles, with a touch of magic and
mysticism created by this wonderful community.
The rune logo is cool! Does it mean anything?
The two Norse runes featured in our logo, Sowilo and
Raido, come from the Elder Futhark alphabet, the oldest form
of runic alphabets. Sowilo means strength, power, success,
while Raido roughly translates to ride, or journey. Together
they form a bindrune, drawing the power of both into one
creating a charm to ensure a successful endeavor and
bringing a bit of luck to your desktop.
Why is it named IRON165? Wheres all the iron?
The iron industry essentially shaped the industrial
revolution of the 1800s. Its ubiquity has led to its
inclusion in nearly every industry. Iron is used to create
many of the tools or machine parts we use today.
A
keyboard is essentially a modern, but basic tool we use
daily and we kept this central in our design choices. While
beautiful, we placed function over form when designing the
IRON165. In its simplest form, it had to be the best at
being a tool first. Something durable, sturdy and a pleasure
to use.
While not constructed entirely from iron
(although steel is made with iron), we felt this board
embodied the more abstract sense of the word. Iron is
strong, iron is reliable, iron is long-lasting.
Whoa! Wheres the ISO support?
We will support ISO if enough interest is shown, but
all of our plate files will be made open-source (including
ISO) regardless. So even if youre an avid ISO user and we
dont have an ISO plate, youll be able to get one made. We
will also be optimizing our ISO plate for consistency, just
like our other plates.
The PCB will support ISO
out-of-the-box.
What parts will be user-replaceable?
Our hope is that everything, except the case itself
will be user-replaceable in some form or fashion. One of our
main goals when designing this board was to make absolutely
sure that no IRON165 will ever become a glorified
paperweight.
The renders are amazing! Wow! Who did those?
All of our renders came from the amazing Abec13! We
cant thank him enough!
Interest Check Disclaimer
Keep in mind this is an interest check.
Nothing, including options, pricing, etc, is final until
the GB starts.
This IC represents the most correct, up-to-date information
we have regarding the Iron165 at this time. Based on
prototyping and manufacturing samples, some things may
change.
We will be announcing any changes, if any, here
first, and on Discord as well.
Shoutouts
My most sincerest thanks go out to the other half of
Smith + Rune, lBaron. Without you, this board wouldve never
made it this far.
We want to thank those that have
supported us from the very beginning of this project,
including Langelandia, bhk1004, Spade, Eskimojo, Full /
Aslejoh, Minterly, Oldcat, Capsy, and the rest of the Gray
Studio and TYL discords. I likely missed some names, but you
know who you are.
We also want to thank the community
as a whole including the designers, vendors, and of course,
the streamers and content creators. You are part of what
makes a project like this so fun and rewarding. Watching
this community grow has been incredible!
