I have a 6,000 bu bin with a floor and fan. The past two-three years I have been planting a shorter season corn and getting to 16-19% moisture and then running the fan untill cold weather. That bin is usually less than half full. I am tired of climbing the bin to open and close the lid and today bought 5 roof vents off Craigslist for $25 each. His bin roofs were damaged in a hail storm and the insurance company replaced the roofs and vents. Any tips on the installation? Anything I should not do? I have a small Amish crew coming Monday to help finish putting the new silo doors in and we would also like to do the vents. Thanks Tom
 
It's been a long time since I've worked with them. As I recall, when the roof panel was punched for a vent, they folded up a little edge all the way around the hole. Seems like it would be near impossible to recreate that, and it would be difficult to keep them from leaking without that? But I suppose there are different designs?

The greatest impediment to moving air through grain is the roof. You can't have too many vents. Best of luck. I'd like to hear how you make out with that project.
 
I've installed quite a few, I used a 4" grinder with a cut off wheel to cut the opening. Position the vents where you want them, mark the holes and drill before you cut the hole. Cut the hole a few inches small than the vent size and then cut diagonally to the corners so that after you bolt the vents down, you cut reach in with a hammer and bend the roof tin up so that water can't get under the vent and run into the bin. Caulk is your friend, don't be afraid to use plenty so they won't leak. Most of all, BE SAFE!!!

I have done a lot of fabrication and repair. Cut the hole a little small and radius the corners. Then take an adjustable wrench or a sheet metal vise grip and you can flare the edge up. May need to do this in a couple of stages. Maybe practice on a scrap piece first. Hope this helps.

A post that says be safe in capital letters and
shows a man on a ladder that is sitting in a loader bucket.
Thanks for the laugh but please follow your own advice.
Ladder in a loader bucket is way past asking for it !
 
(quoted from post at 09:33:28 05/10/20) Forgot to add; I'm a trained professional, Kids don't try this at home!!!

If you were a trained pro, you would have a ladder that is long enough.
 
Anyone that puts a ladder in a bucket is not trained professional, would get you fired from any job site.

I hope your are happy I had a long enough ladder
To install my security light. Actually I put the ladder against the barn to see how high I could safety go before drilling the hole.
I was tempted to post a pic of a shorter ladder in the Kubota's bucket just to stir the pot.
