Glue
John,
Very true about resorting to glue. The only reason I thought that might be why the top was frozen shut was because I considered doing that to my '68 and THIS is why I didn't! So we will just add "tub gasket" to the list of parts for this little puppy.
In the meantime, the three tub bolts are next and I'm starting with those this morning. I sprayed plenty of WD-40 on them last night and they have soaked all night in it. Going to try the old clockwise/counterclockwise on the bolts and hopefully they will pop loose.
I have a feeling the rust issue is just going to be in that one area where the leak is. It otherwise is looking relatively rust free so far. Maybe it'll earn a spot in the basement today. Who know?
Thanks for the encouragement! This is the first "new" machine I've had in 5 years and first one I've worked on in 2 years. I guess I'm a little rusty myself.
