Nice build. I just did scissors door yesterday and did something similar. We had 30+mph gusts during my install and I was able to do it solo and the doors did fine. The sandbags at the bottom did their job. I like your bolt idea because getting in and out was a pain so I’m doing that today
Great video. I'm in the process of doing this myself on 4 FF Quonset tunnels. It's great to see someone else doing it and picking up some tips. A few things I did differently - you decide if they are worth doing. I put duct tape around the ends of the posts to protect the poly. When I open the doors, I tie the pipe to the long tension rope that holds the large sheet of poly to the bows and then tie off the other end to the wind brace. The pipe ends up outside the bow and held tightly in place, and the poly on the door is gathered somewhat. The looser the pipe and poly on the door are, the more they will catch the wind and bounce around - I am afraid that the pipe will rip the poly if held inside with the Bungie. I also used a length of chain to hold the 3 pipes together. I used the bolt to hold the chain near the bottom of 1 of the pipes. I wrap the chain around all 3 pipes and secure it with a carabiner. I don't want to fumble with a wingnut with cold fingers during an ice storm.
I installed my scissor doors on my Pro 100 FF quonset hut and they held up well until the end of the year. The clamps will begin to loose integrity and I had mine pop off the north end in a 60 mph wind. I did not tech screw them in as I didn't think I needed it. Wrong. I also put my posts on four feet centers and concreted all of them in the ground. I had 80 mph winds with no ill effect. I just clamped my doors to the last bow on the outside. We live in Oklahoma with lots of spring winds. I installed another straight post halfway between the middle post and the bow. This way I could clamp a door post to the second post, creating just a quarter opening for high winds early in the season. I also put plastic fence used on construction sites on the open ends to keep deer out. Worked! Also put it on the sides.
Thank you so much for making this video! For the past couple of weeks I have been considering using the plans I downloaded for these doors, and just came across this video today. I really appreciate your work on this video!
wish I'd found this before I built my tunnels! We've been looking for a good solution, This may be it! Oh, and we had the same issue with the plastic at the base of the tunnel on the end hoops.
Living in Alabama I don't deal with the same cold that some of you probably do (rarely gets in single digits), so it has never been too much of a problem. I am also only growing cold weather crops in mine and am not heating them. But you could probably use a foam seal between the two if it was an issue.
Rock Bridge Trees We had some pretty strong winds right after I installed them and they held up great. Some of the clips came off since I hadn’t attach them with the screws yet. And I may eventually run the wiggle wire all the way down to the ground and maybe along the bottom of the side of the tunnel a little just to secure the plastic better.
Mine did great until the clamps weakened. I also didn’t screw everyone down to the pipe. Their is a system sold online that has a bracket at the bottom that is cemented or driven into the ground. The bottom of both pipes have holes drilled into them that correspond to the hole in the bracket. Line the two post holes with the bracket pole and secure with a bolt. Very secure
Great video. I appreciate you taking the time to make sure camera angles are provided where you can really see whats going on.

Nice job on instructing us in how to build the scissor doors. Thank you.
Thank you so much for taking the time to film this. It has helped me out a great deal!!

Great thorough video. I’ve been looking for ideas to do scissor doors on mine. I don’t need to look no farther. Thanks

Thank you for all the detail and tips! Building some of these today!
Thanks for the great video
How many times have you lost that wing nut?
Fill a length (16') of 2" PVC with sand and cap the ends. You can tie a rope to each end so its easy to roll off the flaps. WahLah
What cut the doors one foot shy of the ground?
very cool!!!
Did you have to purchase the additional materials to create the scissor doors or do they come with the kit?
There is enough poly on the roll that comes with the kit, but you have to buy everything else.
@larryheidkamp Got it right. Plastic comes with the kit from Farmer's Friend but you have to buy the rest.
Seems to me that that open seam would be pretty worthless in winter winds. The cold winds would just flood right in.

How do these doors handle high winds?

Just open the ends to ventilate your tunnel.
