Yes I did. Was going to do what you said, then looked at it again and realized that I dont' even have to put that old cap back on so I cut a 1.5 inch wide piece off the top. Its been a hell of a long day. The "person" that did the last transom screwed the 2 pieces together with SS screws. Found by my chainsaws today....
Anyway gotta go sharpen a chain on the 30 incher and cut some more Modnay nite. Have a few hard spots of wood that dont want to saw out real good and the glass between teh 2 sheets is giving headaches but I suspect by 5pm Monday I'll have some type of cutting wheel on like a hand crank drill to get down in there 25 inches down and cut the bottom of the glass loose.
If all goes well I'll have some longhandled chisels for Tuesday to clean it all up, glass in a few spacer blocks, glass in a few edge areas, figure out how to back up the exterior transom with a sheet of 3/4 ply and I'll be ready to mix up 2 buckets and pour the new transom in.
I remember the itch again from working in a boat factory! Yuck.
