For simplicity you would need a shaft puller, a propane blowtorch and a butane blowtorch as well as a Stanley knife. You need to use the propane blowtorch to soften the ferrule before you remove it by putting the Stanley knife flat with the shaft and cutting it off. You the put the club in the club puller and crank it until it is quite tight, you then use the butane blowtorch to soften the old epoxy resin, you will need to keep the blowtorch moving to avoid any damage, it may take about 30-40 seconds and you will see it loosening. You can then simply pull the head off with ease, the head will not be hot as long as you handle it at the toe. You can use the Stanley knife to remove some of the epoxy from the shaft. For a steel shaft repeat the above, but use the propane blowtorch to soften the epoxy resin as it burns hotter. However the easiest way is to take it to a Golf shop and get them to do it, if you buy the shaft off them it will be rather cheap, but there may be a nominal charge if you simply bring a shaft for them to fit.
