If you just want to take a drive, I'm 2 hours south of you. Brother, do I have wood and a full wood working shop. Plenty of Walnut scraps you can practice on. Or, just PM me and I'll give you all the info you need on sanding, staining, and refinishing. Or, I can give you my phone number and we can chat about it. It isn't too tough to do. It's just tough to work up the nerve to do it. But, maybe the stock isn't Walnut. If it's birch or some other inexpensive white wood that a lot of the manufacturers used and still use on the less expensive 22's, it can be tough to get a good even stain. I've had success with that too.
If you want practice wood and don't want to drive all the way to my place, go to a Woodcraft near you. They've got any wood you need. I've been to a few of them in the DFW area, so I know they are a short drive from you, wherever you are. And they have everything you need and the stuff you didn't know you needed till you see it.
