Re: Bamboo Bar

Tom I decided to do a test on my bar as well since I really only posted a photo of it racked with 70# total weight. Here is a video of 140# on it. It is definitely more stout than the PVC as you can see pretty limited flex in it. If you went with the solid fiberglass bar I'm guessing the thing would hardly move even with bigger loads on it.

Wow you held 140 steady! I was very humbled by 120lbs lol. I definitely see that fiberglass is superior, if I end up using this regularly I'll make the upgrade to fiberglass.

Re: Bamboo Bar

Thanks Tom! I've always had a decent bench press, I felt surprisingly good on this despite not benching in over a year (sternum and low back injuries). Starting to feel the DOMS now though...

FYI - I made two for $94 shipped. Your shipping will be cheaper I would think (mine was $25!). The company where I got the fiberglass from is in Georgia. Using a solid fiberglass rod adds $27 to each bar (so for me, would've been about $75/bar - still way less than the bandbell bar but I wonder if it would be too rigid). Probably not needed for us mere mortals. I'm looking forward though to loading mine up more to see how it does. I think it has way more capacity. Not 500# like the earthquake bar but my 1RM was just over half that so I think I'm good...

Re: Bamboo Bar

Mike, question for you:

On your original instructions I saw, if I read them right, you take a 1.5" OD tube and cut to 58" long. Then, you take two sections of 1.25" OD tube, 38.5" long. I assume you basically insert one into each end of the larger tube, and those sections meet in the middle of the tube? That leaves you with a bar ultimately 77" long. Why not just take one 77" long piece of 1.25" tube and slide it through?

Re: Bamboo Bar

Mike,

How much weight have you put on your bar? Not benching, just testing the strength.

Re: Bamboo Bar

I used 1.25" sch80 with 1" sch80 inside to double the wall thickness and glued 1.25" caps on the ends so the 1" wouldn't slide out. Ive loaded 80lbs per side and it held up fine just to test it.

If you purchase from home depot or Lowes the sch80 pipe is grey and will be in the electrical section its actually called conduit. The white PVC in the irrigation section is usually only sch40.

You are correct with the assembly. It was all about the shipping - if the length can't fit inside a 59" box, they charge you for a 70# package. So that is why I had the stuff cut. Otherwise yeah it would've been nice to have one complete length. But the 3M 5200 adhesive is totally bombproof stuff and the bar will break before the adhesive does.

When I told him what I was doing, he suggested I go with the fiberglass rod because of the strength. You saw on the video the bar hardly bends at 140#. I actually did it again and since I was still sore was much more shaky!

You know that 140# is the most I've loaded it. I will put on at least #200 for testing purposes and post photos. I think I will get out the saw horses and see if I can simulate the hand position of a bench press so we can see the flex in it. Using the rack position won't be as accurate as the closer bench press hand position.

If I were a beast I would probably go the solid rod - it is still substantially cheaper than the bandbell bar and will be much stronger than tube. As I mentioned you could build two for $75 each. Not too bad really.

Re: Bamboo Bar

Okay here it is with 200# on it:

http://gingym.blogspot.com/2014/01/d...d-testing.html (wfs)

I'm thinking of doing a mod to improve it, should only be about $20.

Awesome Mike! How do you think just a solid 1.25" rod would be with no 1.5" sleeve over it? Then just glue 1.5" slots for the bands. Too stiff you think?
