Can't believe you got rid of the ski !!! Don't take this the wrong way,You've got great vision but no focus or patience. That's was a huge task and great looking ski. I'm 34 and I wish I had the talent you have when I was that age. These older skis are always a lot of work but you have to take your time. I've got a 91 550sx that I have owed for 10 years and have never had any major issues with.
I've burned my self out with working on to many things at once. Don't take this as a negative post because I'm not shooting for that. You have got tons of potential in just the one build I've seen. Don't slow down on what your doing. Set some goals and you can benefit greatly,by having fun or making profit.
Good luck!
