I am planning on making my own thick barbells for Benching an Delt Presses, In my research I found I need pipe with a 1-1/2 Inner Diameter with a 1.9 Outer Diameter, then the guy @ the iron supply asked if I needed Schedule 40 or Schedule 80. I know the higher the schedule # the heavier it is, but what about its strength. I ask mainly b/c of the price difference, the 80 is double the price of the 40. So basically what I am asking is the Schedule 40 going to be heavy duty enough to hold loades of great weight, are should I opt for the schedule 80.

It's not so much how much they weigh, but the ability to bear weight is what I am concerened about.

Lets use 300lbs as example, should the schedule 40 should be able to bear the 300lbs just as well as the schedule 80?

Thanks for the help also, it's appreciated

I have next to none with experiance with what strain can be placed on steel piping.

Either will be ok for a dumbbell. Neither will be enough for a barbell. You can put the pipe around a regular barbell and that would work. Or get a length of cold rolled steel cut to length.

Thanks.

Oh I know, the Pipe alone weighs 20lbs roughly. Not that heavy so I'm going to be welding an older 22lb weider plates on each side to act as "collars" of sorts.Making the bar & improvised collars roughly 64lbs. together.


You can put the pipe around a regular barbell and that would work.

I've tried to do that but the interior diameter of the pipe doesn't allow it to pass over the inside collars of the bar.


Or get a length of cold rolled steel cut to length.

The cold rolled @ the place I am dealing with is quite ridiculous...but it is a good thought and it is a long term investment. I allready have a 5 foot cold rolled shaft, (bought from elsewhere that has since closed) that weighs in @ 55lbs. alone. So a seven foot for a Rack/Bench would weigh in @ 77lbs.

My thick bar is a six foot piece of 1 1/2 galvanized pipe and I've DLed 385 on it with less bowing than with my cheapo "real" barbell.

I use 2" O.D. pipe on the inside of an oly bar you have to take the bar end off then put it back together.
