RE: Indoor Range Target Construction??
Rack - One of my local archery shops have constructed, what I would guess to be the most "inexpensive", yet durable archery stops that I've seen. They went down to the local SBC (Telephone Company) and got approximately 150-200 phone books (last years editions-free) and stacked them tightly together and then placed a 2x10 on top and wrenched it down on threaded bolts.
It's been there for two years and still going strong. The only thing negative that I've noticed is that you get a paper residue on the end of bare carbon shafts. However, it does scrape off easy enough. I haven't seen that problem on aluminums.
They placed the books so the binders would all face to the left of the archers.
