I just found this topic. You're welcome Jim. I can show you how I made that seat (and keep it in place) any time. Also, just after ice fishing season, Bass Pro will have their padded bucket seats (slightly smaller opening than mine) on clearance...$6 to $8 or something like that. My latest "improvement" project is to figure out a way to carry ice rods in a more organized way and also use the bucket as a rod holder while fishing.

About your rod holder on the bucket you can do 1 of 2 things put screws in the bucket in 2 dif spots and knotch some pvc pipe to hang on the screws to hold your rods, or 2 use rivets threw the pvc in 2 different spots and through the bucket my grandfather use to do both of these things.
