stuck brake drum

[mrtint]

Hello,
I was given a Jacoben 91 utility cart (ezgo marathon) from a golf course. I am finding out it isnt so free although I cant complain because it runs great and came with a charger but I decided I wanted more. They had cut all the accesories to the cart (horn,brake lights,head lighs,horn and turn signal lights) so I decided to rewire everything and with some searching was able to find everything I needed on this site but nothing on stuck brake drum. Thanks to Andy4639 sticky on ezgo brakes, one side went exactly as was written but when I got to the other side and came time to remove the brake drum it was stuck!! Any ideas on how to remove this? I did a search but only found two post and none addressed the problem? Here is what I tried so far
1)removed wheel
2)removed brake cable
3)removed big nut holding drum on
4)turned star wheel all the way so pads realesed
5)stuck drum so hit drum with hammer-NO LUCK
6)still stuck so hit with BIGGER hamer-NO Luck
7)sprayed with rust buster and let soak over night-NO LUCK
heated drum (with map gas for plumbing stuff)-NO LUCK
9)stared at it-NO LUCK
10)went to auto zone and rented a puller-NO LUCK

11)attached a slide hammer to the puller-NO LUCK

12)heated again (with puller attached) until smoke was comming out-NO LUCK
13)banged with a sludge hammer-NO LUCK
14)unbolted the rear plate and tried to pull everything off-NOTHING
15)ASKING FOR HELP

ANY IDEAS WHAT I CAN DO??

thanks
Robert
