Man, that's great, Moxie. I love ingenuity and do-it-yourself projects. I may not be able to build a crossbow, but I can build or make lots of other neat stuff. That's the outdoor way!
I'm planning to build a wheeled box to protect my new Spot-Butt target from the elements and make it portable ... sort of a range shed that rolls. Hope I can post some pics when I'm done.
I guess I didn't word my reply well enough! I knew you didn't build the crossbow (at least, I assumed you didn't) ... I just meant that while I might not be able to build something so advanced as the crossbows we use, I can build a lot of useful accesories, like the one you have built!
