Welcome, as well. . .and I agree with machine! I'm not familiar with the airgun you mention, but recrowning can get pretty involved. Have a pro do it--a machinist or a gunsmith.
BUT, if you want to do it yourself, its not beyond most DIYers. First, find out if and why you need a recrown--damaged crown or inaccuracy issues are the usual. Second, find out if you need/want to cut the barrel--if so, how much do you want off? Third, how handy are you with basic tools?
After answering all that, and you still want to recrown--do your research. The NRA mag and one of the British airgun mags had a good how-to article several months ago, but you can always go to the bookstore or online to research a method. A good gunsmithing book should have the info.
Smoothing a crown involves just plugging the barrel with felt pellets and some lapping compound and a 1/4" BB or round-head screw. Work it until it looks right and clean off.
Doing a full barrel job (cutting) involves masking tape, level and square, scribe, hack saw, and the above, along with a drill/Dremel and brass brush bit. I won't go into detail, but expect a few hours of your time and a lot of metal filings--so don't forget to wrap your gun and secure it in a vice of some sort.
Good luck and let us know how it goes if you decide to go for it!
