Installing push rod tubes
Does any one have any suggestion on installing push rod tube in a fiber glass fusealodge that has three bulk heads, before you reach the tail end of the body, we have tried feeding the wire in first and sliding the tube over the wire and that does not work as you can't run the wire in that far. The plane is a AK model Laclair 120

RE: Installing push rod tubes
Bob,
It's doable situation, it would great to see couple of pictures from inside the fuselage that shows where and how bulkheads are glued in.
I hope fin and stabilizer are not mounted on the fuse as yet coz that will make things more complicated. I'm surprised that manufacturer short sighted this area altogether!

RE: Installing push rod tubes
First thought that comes to my mind is a brass tube.... which is about the best way to cut holes in wood, and I bet it would decently in fiberglass too.. The length could be the only drawback.. but you might be able to extend it using a dowel, or something., that is if you need too.. don't know... What you do though, is sharpen the inside diameter with an Xaxto blade tip. Just put the tip into the brass tube, and slowly spin it, and you'll see the blade sharpening the tube. That tube sharpened like that will cut through alot of hard wood, and again, I believe it might work on fiberglass.. .. I keep 3 or 4 different size tubes handy for cutting holes in balsa.. they will go very sharp angles.. very cleanly.. I never drill balsa anymore.. and the tubes do go through lite-ply sometimes too.. I hope this helps.

It appears that the holes have been drilled already. If the tubes will fit in the holes, I use drill bits that are 24 inches in lenght and sized so the tube will slide over the bits and into the hole. I will then push the bit into the plane and then slide the tube over the top of the bit. It can take some wiggling and jiggling, but it is doable. The brass tubing will work as well as long as you can find long pieces of it the right size. Good Luck, Dave

The longest rods that are shown in the manual are supposed to reach from the servos' bank to the elevators and rudders.

Using one of those as a guide, or any longer wire or wood rod of suitable diameter will help insert the plastic tubes into the holes of the formers.
I recommend not using the supplied EZ connector for the elevator servo arm.

RE: Installing push rod tubes
Hi!
Cannot see the difficulty!? Push the rods in fron behind in the holes that are already made in the formers! There are holes made in the rear part of the fuselage I assume..?
But why not use fishing wire insstead? Much lighter and much easier to install!

Reply to all, when all else has failed look around and REGROUP. Cut a 1" by 1' hole behind last bulk head and install. Then add reinforcement to hole and reinstall cut out. Reglass and paint. Its on the bottom and can't be seen. Thanks for all the replys
