Grandkids are going to have a blast on that! My cousins and I used to play in my grandfather's barn. There were plenty of things that we could have gotten injured on. We never did. Also used to play in my neighbor's haymow. We'd swing across the barn on the hay rope. Neighbor girl jumped into a pile of hay and stuck a pitchfork through her foot. She survived.
Im not in love with the ubolt mounted only to the top rail of the frame. Id worry about metal fatigue at any of those welds... id gusset the top rail to the bottom rail with a sheet of diamond plate, and attach into the uprights as well. Love everything else though! Making me add another thing to my wish list, starting with a barn! Lol :-) love your vids Mark, glad to see you back !
@@Blueglow I dont mind the Ubolt per say. All of that weight is concentrated to only the bearing surface of two nuts. In order of preference, I might Add some sort of flat stock to the rear as described previously and may be use 2 u-bolts. Im not an engineer, may be worried for nothing. Like anything else, the stronger you make one part, the weak link moves to somewhere else. Id kinda like to have the weak link designed to have a backup. Failure could be simply , oh gosh! Thank goodness I had a backup...
To me the rollers are def in contact with the strut under load. The further you are away from the u bolt where the hoist is connected the higher the load on the strut is. Remember torque equals force x distance, which creates a moment. The best way to do this and not have it under load is pulling from the center of the platform on the top.

My only concern is the position of the lift cables creating outward force on the rails and the U bolt. Great build. Thank you for sharing.
Fun show-n-tell, Mark. Your lift is a cool way to avoid injury (and dropped equipment!) when climbing narrow stairway.

Mark I've learned so much from your tube electronics videos. You are now officially my hero!
Man! I wish I had your barn at my house!! And we want to see the cars you’re working on!!

Any recommendations on what to use beside the U bolt?

A U-bracket that cups the top rail with a rated shackle pinned to the bracket.
Nice build, saves your back and heart. Welds look great. I get a lot of this stuff at vevor.
very nice and thank you for the physics refresher : )

Nicely done!
+1 for the Cornwalls
Nice.
If anyone has sourced 20' strut at a better price comment back. I've had no luck
Great design. Thanks for sharing.
