Thank you.
I was really not looking forward to that task, especially having tried the cardboard liner in my '37. That was a fiasco! I ruined two liners and had a heap of frustration! I ended up using the ABS liner instead. That was about 10 years ago. Every time I look at that one it bugs me that a piece of crappy cardboard beat me. I got the ABS again and decided I'd give the cardboard another try. This time come hell or high water I was determined or ruthlessly stubborn. As my instructions above indicate it was a battle. But, the satisfaction in victory made it worth it! Buddies offered to help, but I politely declined. This was between me the cardboard and Sparky!
