I'm a mechanical engineer and that bench is a big mistake. You need a one good beam trough the midle. That gap is going to kill someone. And legs you make with 2 beams. And you also lock the leg only in one direction, you should lock it in both directions, like Rogue locks their fold rack beam with the pin. Also Torsional stress is a Problemm. My English is not good.
Comments starting with "I am an expert" are easy to dismiss. You might have a point, but it's lost in hysteria, no one is going to get killed using this bench. I wouldn't use it for Strongman bench-presses, but it's a serviceable design for home use and probably safer than the bargain basement crap you can buy on Amazon. The end user who is building the bench will the be the ultimate judge of their use case and the serviceability of their construction.
I am an engineer too. Using 1x1 and 1x6 in an intelligent way, my bench is extremely light and holds well over 1,000 lbs. An attachment using 2x4s adds decline and incline capability. I also have 2 trade tickets, so the tools are free, and materials were ~$60.
Yeah, I'm not an engineer but using basic physics and referencing the strength of plywood says that focal point of weakness can handle up to 50 lbs of shear stress before structural failure for a 3/4 in thickness....I know some my rebuttal that he laid on it with dumbbells and nothing happened but that's because it's spread through the bench and not at that point. So I would heed the engineer's warning. This can kill someone if they decided to bench heavy.
@@j.johnson8360 You're the one that pointed it out. You just repeated what was already mentioned in the video several times. Just say you didn't watch the video.
I'm sorry to sound like a downer, but someone is going to ge seriously hurt using that!!!! That bench needs a full-piece rail of some sort running down the length of that pad and those need a brace or gusset of some kind to take on any kind of torsional stresses. I say this because I like this channel alot- but I would strongly consider removing this video.
It makes me sad that I have to say I completely agree with this comment… Love the channel and the creativity but this design is very unsafe and unfortunately this video should definitely be removed. Good effort and great video content, just a mistake in design.
I hope that bench is trashed and never used. It's going to kill someone who is lifting heavy. There is no support running lengthwise, it will snap in the middle. People, please do NOT build this bench.
Get rid of the plywood and make a solid top out of some 2*6's or 2*8's. A strong flat bench is better than a sketchy adjustable bench. That's what I did at the start of lockdown, solid as a rock. DIY cable systems can be extremely economical.
My DIY cable system was $140 for materials and I use it with 150lb weight, but it will take a lot more. I used a 15' rope with a monkeys fist on each end, making it 18" or so long, as a tricep Y handle like the thick rope with two plastic ends that you see everywhere. Weights were free as it fits my normal weights that I have anyways.
You are correct, a strong flat bench beats a sketchy adjustable. Stability is key when the weights are huge and failure is disaster.. his base is big enough as long as it can take the large moment the center post (and plywood attachment) will be subjected to. Depends largely on how big and strong the user is I guess.
Absolutely love the DIY rack you guys made. I use mine All the time. Once I added a few modifications I fell in Love with it and just don't feel the need for an exprensive power rack.
Yeah, I'm just buying the bench. I don't mind Garage Gym DIY, but can you do a GGR over a Rogue nordic curl bench vs a Titan floor GHR? I think that would make for an Awesome video. I'm looking to get one of those two. Thanks
Never thought I'd see the day when steel was cheaper than lumber... But hey, it's been bad the last couple years! I ended up buying a power rack. However, concrete is cheaper than iron weight plates, so... Yeah, still lots of DIY to save money! Thanks for posting these projects, no matter the lumper/steel price differential. Who knows when things are going to change, again.
Sorry guys thus is the worst design for a DIY bench I've seen lol the entire weight supported by the bench is held by a 12" wide strip of ply wood... I wouldn't trust it just sitting on the bench if I was a big bloke 😅
I'm still waiting for an ultra budget rusty bucket gym review. Build a full home gym using only the cheapest marketplace and Craigslist and good will and garage sale finds. Give yourselves two weeks and see what you can manage to put together. You guys are always saying how you can find good cheap stuff second hand..well. let's see it happen!
With more and more people returning to franchises like OrangeTheory, CrossFit, F45 and other such community based workouts…would you guys consider home gym series for people trying to supplement those workouts with other programs? Or visiting different types of athlete’s gyms? Asking as a washed up athlete looking to chase the next set of goals.
I would love to see a stress test of this bench like how much can the best hold on top of it before it collapses bc of the folding leg. Bc I'm heavyly debating on doing this but make both legs fold down
I would’ve at the very least doubled up the plywood on top, if not run some 2x4’s along the edges. It’s just too sketchy in the center, now it can’t be used for strep ups, and I wouldn’t feel comfortable doing bent over rows. Other than that though, it’s a neat idea
If you're benching under 250lb, this bench should be ok. It would be appropriate for me. Yes, it could be reinforced and gussied up, if you wish to extend the weight capacity. The vinyl seems to need more stretching, or might quickly wrinkle. I doubt that with 250 lb the plywood top will snap in half. Plywood is much stronger than that.
I have no idea why I’m watching this video. I have two adjustable benches in my gym. I literally have twice as many benches as I need. Home gyms are a drug man.
If live out middle no where and have spare wood good idea. But noww pandemic lock downs over, people are giving away a lot gym equipment for free or next to free as they move and want get out of where they live or were stuck living.
Horrible design. That bench will flex and/or snap in the middle with no support. GGR must be running out of stuff to “review” if they’re putting content like this out. You’d think after years of “reviewing” gym equipment, they’d know what a good bench looks like.
Nice and simple....when I built my bench I went all out and made it incline up to 80deg. Flat and decline up to 20deg. With adjustable seat. Still going strong
You should have hired a carpenter to do this. This bench is a terrible idea. You need a beam that goes the full length. This will break and hurt someone. I recommend that you refill this and get a Carpenter to help you

That is a downright dangerous design, it relies on the plywood alone for structural strength in the middle.
Cost of lumber is the same as new bench right now lol
And quality padding and vinyl...
It's like yall didn't even watch the video.
@@AaronHoward81 yes we all know that at the end it states it’s not economical. Thanks for pointing out something every heard.

Cool design. I think the swivel post is a nice idea but ultimately takes away from the overall stability of the bench.
What's the rating on that threaded rod? Better be more than your bodyweight and 1RM...

Not only that but what’s more concerning this repetitive stress cycles with wood as the material.
Like the ingenuity but.....lumber alone (not counting your time & tools) will cost you more than a new bench would.
Yes, he mentions that several times in the video.
@@AaronHoward81 he does and it's a great video.....just not seeing the point I guess. Not looking to hate
What kind of benches are you guys buying for so cheap? You can get a 4x4 at Home Depot for $15.
Cool Vid! COOP!! Why don't you ever review gear from Wright Equipment? They have good stuff!
Can’t wait for the wooden Airbike video😂
Liking the diy videos with our fav as-sam-bly
Its going to be the worlds most wiggly bench .
I love all the videos Sam does, do more!!!!

what are the measurements of your base????
Sam > Coop
Good job Assambly!!
Why buy one when you can spend hours of labor with the same amount of money and make one yourself? - Sam
Still waiting for the DIY treadmill.
Best fold flat weight bench at every price category please

@repfitness please sent these folks a REP Open Bar for review.
Wow I can't wait to not do this
Pressure treated too for outdoors!
That looks sick!
Does Sam lift?
No really, I am serious
Nicely done Sam!
Good wood is hard to find theses days! LOL!
Excellnt
If live out middle no where and have spare wood good idea. But noww pandemic lock downs over, people are giving away a lot gym equipment for free or next to free as they move and want get out of where they live or were stuck living.

Where’s coop ???
Thx for the video
Just because you can doesn't make it a good idea.

Delete this before someone gets killed. Terrible design, surely snap in the middle.
Nice and simple....when I built my bench I went all out and made it incline up to 80deg. Flat and decline up to 20deg. With adjustable seat. Still going strong
Very well asSAMbled.
Dude, put a beam under the plywood
Thanks Assambly Sam. Great effort. You are a talented individual......Maybe your friend Coop can learn something from it 😛
🥸🥸🥸
Nice project Sam. It might not be economical, but the video was interesting nonetheless!
Nice job "As-SAM-bly" !
Lol screw barr....Sam it's called a threaded rod 🤣 you screw barr...lol see what I did there
Sam gets a Like.
Nice!!!! Good job but it could use some knurling.
