Because I stapled the screen to the main frame and then the 3/4 shim on top of the screen. I was kind of contemplating laying another strip over it and offsetting it.Try a regular lumber yard, they usually have the smaller screens... and why rip them all apart? can't you just simply remove the screen you used, and install the new?
I made 5 like this and I thought it was ok until I noticed some wasps trying to get thru it and although I never saw one actually go thru, it made me wonder and I figured they could and if they could, so could the bees, and other bees in a robbing scenario.Like StevenG said, I don`t know why you would have to rip them all apart. If you really can`t remove the #4 screen, then at least you should be able to staple #8 cloth on top of it. If not re-examine your design. How many have you made like this? What ever you do, don`t use the 1/4 inch screen in your bee yard . It`s way to big.
I don't know about any of you but the shipping is starting to kill me. I have ordered alot lately thru Mann Lake and Dadant and prices weren't bad until I started seeing $40 to $50 in shipping. Was going to order 2 packages of bees recently until I noticed the shipping was higher than the bees.I get my #8 screening here:
They have fast turnaround
