<p>Thanks, Ken. I'll be trying out various clamping devices and orientations, and using longer drill bits. Good ideas.</p>

<p>I like the idea of <em>learning</em> by doing and making mistakes, but I don't like rushing in where angles fear to fall. You, John, and all the other better men and women at this than I, actually <em>move</em> me with your generous spirits. This has been <em>the best</em> part of my foray back into flying at a time in my life when it's now or never.

<p>I will probably do it, but when I have plotted out a comfort zone the making of which is a different and separate challenge all its own. "Be sure you're right, then go ahead!" --David Crockett</p>

<p>Wayne, it's really pretty easy. Just make sure you have everything clamped real good so there is no chance of anything moving. One thing that might give you confidence is longer drill bits. With longer bits (12 inch) it's easier to eyeball that things are perpendicular.</p>

<p>Wayne, sure I've made mistakes in my builds, and I've fixed the ones that mattered, and sometimes not the ones that didn't, and learned from all of them. Pick your battles. I did not compromise my front fork one iota by eyeballing it and not using a jig, and I don't want to pay the extra cost that Zenith would pass on to me if they had to set this up in a custom jig and drill it for everyone.

I bought this because it's a kit, and I expected to learn something from the assembly, which I have and consider that education as valuable as the completed aircraft. </p>
<p></p>
<p>Sounds like you're going to pass this on to someone else to drill out for you, which is the great part about homebuilding, 'cause you can. Good luck on it. </p>

Wayne,<br />
You need to get out in the shop and just drill the holes. You over analyze too much. Go out there, look at it, look at the plans, figure it out the best you can, clamp it together & drill it. The worst thing that happens is you screw it up and have to start over. Odds are highly in your favor it will turn out completely acceptable and you will have the confidence to move on to the next project. Best of luck to you -<br />

<p> 3. Ending up with the right sized hole that is perfectly circular, after deburring and smoothing the walls of the hole</p>
<p> 4. Avoiding boogering it up in a way that could weaken the metal such that it could fail under stress even though it might look great to the naked eye</p>
<p> 5. Getting it centered and straight</p>
<p></p>
<p>Note: The center of my concern is drilling something that thick without a jig. I'm gonna ask my mechanical engineer buddy for his opinion. If he says, "just do it," I'll have three out of five in favor--if I'm still chicken after that, maybe I can con him into doing it.</p>
<p></p>
<p>I still hope to hear from the factory/Caleb just why they don't want to pre-drill them. And, do they drill them with a jig or do they eyeball them when they build theirs? My shop is a figment of my imagination right now.</p>
<p></p>
<p>When I get those answers and have a plan that should at least theoretically work, then I can come out from under the bed and just do it. I'm gonna clear it with my retired A&P buddy too.</p>

<p>I'll echo John's last line, <em>maybe</em> if this was an F-18 hitting the deck at 150 mph I'd be concerned, but I can't imagine being able to mess it up so bad it would compromise my plane plopping down and tracking true. I'd guess that's what Zenith felt also. They can build the spars, but leave me the other stuff. </p>

<p>I primed and painted the bottom of the curved plate and the drain hole before assembly. I also liberally sprayed through the drain hole the interior of the gear leg with Boeshield T-9 before assembly. I "think" the hole was centered - but refer to the drawing to be sure - I did!</p>
