This one is mega-fun, and you don't need expensive tools to do it.
You will need:
A heat gun (ours was about $30 from Bunnings hardware store).
Some paint scrapers.
How to do it:
With the heat gun on high hold it over the area of paint you want to remove until the paint begins to lift and bubble.
Using a paint scraper, scrape the paint away from the surface.
Work small areas at a time and don't hold the gun on an area too long or it will singe the wood.
For fiddly bits or to remove that last little bit of paint in cracks and gaps apply a gel paint stripping chemical, leave for a few mins and remove with a steel wool or rag.
Tip: You can get a scraper specially designed for those tricky bits of moulding.
