Thanks guys
I`m giving it a try
The only issue is, I figured out I might use M12 bolts instead. Should that be enough?
And I mean 8.8 strength (does impact load affects what strength I should use?)
Following my previous post on using bolts as a replacement for J-cups in a bench & squat power rack, I came up with a new design:
1. The red base is a UPN 100 welded old elevator base.
2. I use two of these as the poles to support the weight. The bases will be connected at the top back (near...
Right, I used a M11 + wooden block, just for testing.
I plan to use a thicker bolt.
Right, only bending damage, no shear.
Machining a groove...a bit hard. I`ll use wood instead
Thank you all guys, I`ll update if I have something interesting to share here

Thanks, I wish I could slope, but the design doesn`t allow that.
If I secure the bolt with just one nut, I might be able to use half threaded bolts, but the bolt will still have the thread at the contact points with the 6X6 pole.
What metal block would you recommend. Is a 6X6 cm square...
OK, I got you.
The only problem with that would be, it`d require high precision in making the holes.
What bolt thickness should I use for that, if it`s 2 bolts holding a piece of wood, say the bolts are 2" apart [top to bottom] from each other? (are 2" that enough?)
And how to secure the barbell...

You mean resting it on a tall wooden beam?
I know it`s stronger, but I need height adjustment. Cannot just let it be a single beam to hold the weight at the top.
Rest of the setup is that I have an old base from an elevator, a UPN 10 mm. On its sides I`ll bolt the 6x6, and on...

It`s an open roof: sun, rain... I`d prefer steel.
Would adding a block of wood on the space between the bolt and the 6X6 beam suffice to provide the bolt with anti-bending support?
Hi all.
Trying to build my DIY weightlifting rack (bench press & squatting).
The two beams are 60x60 mm (3mm thick) galvanized steel.
The issue is with the hinges. Making a special welded hinge is too expensive.
Thought of using M22 bolts. The Olymic barbell will rest on one M22 bolt on each...
