Hi Hoppy,
Here is my setup for this wooden dowel setup.
I used a 14" long x 1/4" thick dowel rod. Drilled a hole 1" from each end of the dowel rod wide enough for a 914mm pushrod to go in, then used a 1/8" piece of brass tubing and cut a slot from the end of the dowel to the hole that was previously drilled deep enough for the pushrod to lay in real good. Took one piece of pushrod bent one end down to where I had less then 1/4" bent wire. I installed the bent end in the hole and kinda heavily CA'd it in place. Took a 1 1/2" piece of heat shrink tube and placed that over the two ajoining rods and shrunk the heat shrink tube. Once I did that then I put medium CA in the tubing area where it is over the metal pushrod to seal that end shut.
Do this on both ends of the wooden dowel rod.
MAKE sure you have the pushrods cut to exact length or do all the above first and then make your cuts on the pushrods.
See pics.
here is another pic of it as well. Couldn't put 2 images on same page so I added a link to the other.
