Strong Track System easy to install
Jane,My wife & I installed the system on our 40.5 this spring. I had to modify the opening on my mast in order to get the track into the slot.It was easy. Draw the outline of the necessary opening (be generous) on the mast with a magic marker. Using a sharp 1/4" drill, drill a series of holes to the inside of the marked opening. Using a center punch to mark the hole before drilling may help keep a straight line. I used the B&D Bullet drills that have a small tip to start the hole. After drilling all the holes, break out the interior aluminum piece with pliers. Then take a small coarse file and smooth out the edges. I used a Demel tool with a metal cutting tool to do most of the work. The hole only needs to be smooth enough to let the Strong track slide into the opening. The Strong Track completely covers the hole that you have cut or enlarged, so it doesn't have to look pretty.If the mast is down and on horses, get one other person to help install the track. Take the stop pin out of the top of the mast and put a 12" cable tie through the top holes in the track and make a big loop with it. This gives you something to hold onto and pull the track up the mast. If the mast is in the boat, attach the halyard to a slide and tie another string or line to the slide as well. Use the halyard winch to pull the track up the mast and then pull on the string to bring the halyard and slide back down to deck when done.Spray the backside of the track and the mast with an aluminum lube or WD30. Curl and push the track into the mast while the other person pulls or winches up the top of the track. When you get to the end of the track, the remaining track will lay down on the mast covering the opening that you cut and it will extend down to the top of the boom. Secure it with the hardware supplied.Total time to install is about an hour. This includes cutting the opening, lubing the track, talking about the proceedure with your helper, and actually doing it.The performance of this track on my full-battened mainsail is very good. My 52' (luff) drops like a rock to the boom!I think I have some digital pictures of the proceedures if you wish.Rich
