One I just took apart yesterday to take back to the woods and reassemble on the raised (8') stand is the 5th of my modular blinds.
This a look at the 4th one I built a couple years ago and assembled in the front yard, 400',from the house.
I cut 2"x4"'s in half for the corners, I like 5'x5' so add a foot to the sides of some OSB make some inside braceing for the windows to hinge from
Once on the platform 5'x8' made with treated 4"x4"post and 2x6 floor rails, floors is normally non treated 2x6 inside the blind and treated 2"x6" porch. All the sides are lag bolted to the floor. then lag bolts are used to bolt the sides to the front and back. Once that is done the roof is lifted in place and lag bolted in place.
I also at one time used those Amerstep pop up blinds. They worked great set up in advance and brushed in a little. Problems arose when we got freezing rain and the uncovered zippers froze shut. can't open the door to get in or out. can't open the windows to see out.
I sent a E Mail asking them to sew a flap of material over the sippers and they basely gave me the big finger.
That is when I started building blinds my self.
I have used T1-11, OSB, recycled pallets and now plastic board and steel.
Recycled pallet blind I have on our UP property.
Amerstep dog house blind with froze up zippers a useless blind.
A nice no name portable blind except for the almost 20 pounds of weight.
The weight factor.
