Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

simulator cockpit.
This is what Jentron developed:<br/><br/>
[[file:jentron_original.jpg]]
As you can see, it&#39;s very simple and uses easily obtainable off the shelf
hardware.&nbsp; In fact, this particular example was built entirely from the
resources of his local Ace Hardware.<br/>
<br/>I&#39;ve named his original gimbal design the &quot;Mark I&quot; to differentiate it from
<br/>As you can see, the design elements from the Mk I design are present here
with a couple notable changes.:
<br/><br/>
* The pitch axis bearings are two separate components.* Simpler interconnect for the pitch axis centering arm - no need for a hand-fabricated pitch arm.* Reduced part count
Simpler interconnect for the pitch axis centering arm - no need for a hand-fabricated pitch arm. Reduced part count <pbr/>Jentron&#39;s design is perfectly usable in it&#39;s configuration, but I needed
to modify it for use with the DIY Cockpit Project.<br>Besides, I&#39;m a geek and
no self respecting geek can resist fiddling with things. :)</p>
<p>Below is instructions on how you can construct this gimbal for use in your
cockpit!<br/p>
<p>&nbsp;<br/p>
<hr>
and how you can build your own.</p>
<pbr/>One important thing to note - the gimbal is designed to be mounted underneath
the cockpit floor.&nbsp; This is what it looks like from above, in the
&quot;operating&quot; position:</p>

to adjust other parts of the design to fit your situation.</p>
