Re: Conn C melody repadding
You should be able to order the pads on ebay Sammy. I bought some pads for a Conn C Melody I overhauled through Ebay for like $65 Buy It Now, and they were hi quality resonator pads too.
I wouldn't replace the springs unless they were broken or worn thin to where they're about to break. Usually the springs last a long time.
Get a good quality brand of screw drivers, because I have twisted many tips trying to take out those stubborn rods and screws! I would recommend spraying some WD 40 on the screw posts and letting it work a couple days before even attempting to remove them.. Servicing the pads can be tricky depending on your skill level. You want the pads to seat flat in the key cup without any wrinkles, and you want to use the proper adhesive. Just make sure you have cleaned the key cups to remove any oil and the WD 40 before installing the pads.
As for tools, I recommend a pair of small needle nose pliers, a leak-light to drop down the bore, and a spring tool. I made mine from an old tire patching tool, but you can buy them through www.wwbw.com. They're like a screwdriver with a hook on the end.
