Yeah, a hacksaw blade would work, but a dremel tool with a metal cuting disc goes right through the cam pin in about 10 seconds. much easier. Just be careful not to cut at an angle since the bit will eat the aluminum casting like its made out of warm butter. I just replaced the cams and delrin screws on my boat (81 H16) and shimmed everything in really nice and tight. WHAT A DIFFERENCE! I just bought the boat and since I didn't know anything about hobies (or sailing) I just sailed around with the rudders unlocked and the cams stuck permanently in the locked position... One important thing I learned is that spraying WD40 in the threads that accept the delrin screws and then running the correct size tap through it about 5 or 6 times allows the new delrin screw to just slide right in without binding at all. This step should not be skipped. I think it will allow for easier removal next time. I also notice that with the delrin screw inserted and adjusted, a reservoir is created in the area that the spring sits in that will fill with salt water, which cannot be removed without unscrewing the delrin. Do you guys drain that water out of there every time or just let her ride? Thanks!
