Yesterday I stopped by my favorite cheap tool store - Harbor Freight. I picked up this 60 piece #1-#60 drill bit index. Only $10! It will be nice to have this for those few occasions I need an oddball bit.  Here is the jig I setup to drill the ends of the pushrods. First, I clamped a 2x2 to the drill press table and drilled a hole with the outer diameter the same as the pushrod. I inserted the pushrod into the 2x2, used a clamp to hold everything tight and then used a #3 bit to drill out about 1" deep. You can see the electrical tape I put on the drill bit to judge my depth. It worked very well. These flap pushrods are a tad on the thin side, so I didn't want to risk drilling by hand and running running the drill bit at an angle. This method pretty much assures a perfect hole.  I then used a tap and threaded the holes. This took a while.  And the final test. The rod ends fit perfectly.  Lastly, I spent a lot of time planning out the static system. When I say planning, I really mean wasting because I should of just gone ahead of put them in. I won't even go into what my alternative plan was because it would of cost me more time, money and weight. Three big no no's!
