Kenny, Nice looking wood display......my first one was made from the same cedar and I still have it in use, double sided 4'x4' with plexiglass doors. It has Michigan made Broadheads on one side and Signed Arrows from Michigan Archers on reverse side.
A little story for you that happened to me around 10 yrs ago. Say 3 months or so after putting it together and taking it to Kalamazoo Show, I notice there was a drip hanging from one of the pegs and when I opened the doors I found cedar tar on some of the heads and the paint on some of the arrows was getting soft from the fumes. I came running out of the garage with both hands full of Broadheads and my wife was mowing the grass and with the look on my face she thought I'd cut my fingers off, once she found out what the emergency was she rolled her eyes and pulled away and left me standing there with my ordeal to figure out what happened. I guess she didn't see it the same way as me.
So had to let the tar dry or it wound mess up the finish if I tried to clean it off. You can still see the shine and smell the cedar on them today. I sprayed a clear finish over the wood to seal and never had the problem again.
So if you put a door on it you may want to seal the wood first..........Hink
