Hello, Ralph. I'm having a little bit of trouble understanding your descriptions, here. I don't know what you mean by inner and outer window. Do you mean the bottom and top sashes? Could you show me pictures of the hardware you're using? I don't know what you had or what you're using as replacements, so I'm not sure how to lead you from here. I'd also like you to go into more detail on the bulging you mentioned. It sounds like you're talking about the spiral balance, but I don't see how installing a pivot bar would create a bulge in the spiral balance in any way. To be honest, it sounds like you may have picked the wrong pivot bar for the job, but I really can't say until I have a better idea of everything you're doing. Pictures would definitely be the best place to start. |
