If those hinges are held in by giant phillips head fasteners, then there's a special manual impact driver that I have for those. I bought it at SEARS. You get the right size bit, put it in place and twist as if to unscrew the bolt. Then whack the end with a big a$$ hammer. It takes a few whacks, but it'll finally give way. I use all the techniques already mentioned to help like heat, PB Blaster, 50/50 acetone and ATF, never heard of the crayon - but I'm gonna try that too!. This tool is great for door hinges etc. too http://www.sears.com/craftsman-impact-driver/p-00947641000P?prdNo=1&blockNo=1&blockType=G1 ________________________________ From: Julie <julie.hey.ho.lets.go@xxxxxxxxx> To: "tcb@xxxxxxxxxxxxx" <tcb@xxxxxxxxxxxxx> Sent: Tuesday, June 18, 2013 9:41 AM Subject: [tcb] Re: 12 hours Cool.

Well sort of straight. I did stop for food and to cool in front of the fan every now and again. Some grinding. Lots of sanding on the rusty window sills and the drip rail. My hinges for my pop outs are poorly. One moves enough but it seems impossible to get the screws out so I can take it off the hinge to rebuild the window. And the other hinge has the window off but won't budge. I have sprayed it many times over many hours with PB Blaster and I removed as much rust from it as I could. It still won't budge. Isn't there some home made remedies that work better than PB Blaster? I will leave a big ring around the bathtub tonight for sure.
