On the cams, you really do need to lubricate them with something. You can use WD40 to loosen them, but I wouldn't use is permanently. It breaks down in salt water, so you might want to go with silicone instead. If you pull up on the cams with a rope, you will probably just rip the top part off. Then, you are in worse shape than before. Squirt the heck out of it with lubricant, then try to come up under the cam with a flat head screw driver. You should be able to get it between the cam and the plunger ball that locks it. You need to be firm, but gentle or you will mar the underside of the cam and it won't work as smoothly.

There are tools made specifically for that application, but it is a matter of finding one.

I can bring a bunch of battens with me to Hartwell and I can also do the rivets as well as batten pocket protectors. Bring that mast with the broken comptip track and we can work something out!
