Started work on the pushrodsStarted work on the pushrods
The instructions say to "assemble the W-917 and W-918 pushrods as shown in DWG 9." Well, I looked all over that drawing and only saw where you assemble the whole thing after the pushrods are assembled. I found the real pushrod assembly instructions on the Drawing #15, in the upper left hand corner.

I pulled out my wing spar holders and set the big pushrods on them. It was quite obvious to me that these 2 big pushrods were the W-917 pushrods. But I freaked a little when I only saw one W-918 pushrod (which wasn't marked as W-918 by-the-way). Turns out you have to cut this puppy in half to make the W-918 aileron pushrods. Sometimes you find parts by process of elimination.

These guys go in the end of the big pushrods and get pop-riveted in.

These might be a little hard to drill, since they're obvisiously not aluminum.
Chop Suey!Chop Suey!
I had this old metal-cutting blade hanging on the wall from a previous adventure that never came to fruition and decided to put it to use in my chop-saw (miter-saw) and make the cuts on all the pushrods.
Making the cutMaking the cut
Since the deck of the miter-saw is 3 1/2" inches high, I put a 2x4 under the pushrods to hold them up level to cut the pushrods, leaving a healthy portion of the rod in tact just short of the cut mark, since the metal cutting blade tends to waddle back and forth, making a really wide cut.
Nice cut!Nice cut!
Scary as hell, but a nice cut. I squared up the ends with my benchtop sander and then hand sanded everything smooth.
