first post! jib block removal

firstly let me say wow is that image verification difficult lol. took several tries. i found several threads on how that jib block was attatched. i'm working on a 4XXX boat, and i found that it is supposed to have screws. however, i see no screws, and it's REALLY stuck. i'm even contemplating just grinding the whole thing off because i'm going to modern style sheeting. i'm just wondering if the screws are supposed to be coming from the bottom or the top. i got the foam out and looked up and it looks like there are two little bumps in the fiber glass that might be those screws, but it's a little too hard to cut, i would have to grind it. is it common to not find these screws? next question: someone put the aluminum jam cleat behind the cam cleats on with stainless screws. they sure are stuck in there well. i tried extreme heat, and pb blaster, and i get nothing. i guess i'll have to drill them out? thanks all!

I had the same feelings.

I had the same feelings.....but after all my investigation.....and no signs of screws....I pulled out a wood chisel and carefully split the block in one inch pieces and pried them up. Guess what it was held by a white substance. And, it all came off with no problems. Good luck!

ahhh thanks much.

ahhh thanks much. i expected it to go that way. so there were no screws?

Not on my boat.

Not on my boat......and that concurs with another owner who also knock off the wood block with a hammer. I think a marine glue like 5200 was used. OK

My jib rachets were attached with screws on 4086.

My jib rachets were attached with screws on 4086. The trick to getting the jam cleat off is to cut the aluminum with a hacksaw. Cut the cleat, straight down, about midway between the screws. Cut on a slight angle from perpedicular to the mid line of the cleat. When you are almost all the way down to the boat, hit the cut with a ball pean hammer. if you angle the cut the right way, you wiill be able to turn each half of the cleat, with the SS screw frozen in it, counterclockwise. The two pieces will spin right out with the broken cleat as a lever. Harry Carpenter clued me in to this. Phil Scheetz FS 4086

thanks much for all the advice.

thanks much for all the advice. i ended up coming up with the same process as the last post suggested for getting the cleat off, and used a chisel to get the wooden block off. job is all done! i'll put some pictures up tonight!
