I recently made one for my garage for all my summer fishing rods and it turned out great. I took a 1×4 that was 6 ft long and drilled a hole with a circular saw every 5 inches and then made a couple cuts with a jig saw. It cost me all of about $4. I am going to make a smaller version for my ice rods this week using the same process but probably only a 3 or 4 ft section of 1×4. Here is a picture of it but unfortunately its not very close up. I will add a pic of my ice rod rack once its done.
