Just to change shafts you will need.
A bench vise
Rubber pads to hold the shaft in the vise
Heat gun or torch - to heat and loosen epoxy bond.
A good glove to grab the head and twist off while still hot.
If changing steel shafts only no shaft puller is needed, but required if pulling graphite shafts.
A wire brush or equivalent to remove cured epoxy from the heads.
A good shaft cutter
A 48” ruler to measure shaft length
A ferrule installation tool to make that...
