I am about to attempt to make a frame for weight training. I was intending
to use 2" square steel tube, and drilling holes to bolt it together, but
looking online at some suppliers there seems to be lots of different types
available. Can anyone suggest which type of steel would be best to allow me
to drill using diy equipment? I may also try and weld some of it.
Also can anyone suggest a good diy supplier who will deliver to my door?
Thanks in anticipation
As a former weight trainer and very small-time metal worker, I'd
hazard a guess at 16-guage 2" square tube, and braze the joints.
If you look in the yellow pages under metals, you may find a steel
supplier. Most companies will deliver if you pay them (same as the DIY
I'm not really an expert so hopefully someone else here is.
2" square is huge. 2" x 1" is plenty, or even 1" square. Use the
thicker wall stuff if you're going to rest bolts on it..
Ideally you should ream it, but be careful with accurate drilling. it
is worth drilling undersize, then clamping both together and drilling
to size in one pass.
Use the right bolts - plain shanks of the right length. If you take
the weight on the threaded portion, particularly a cyclic load, then
you'll get fretting motion and the joint will work loose. Use washers
and nyloc nuts.
You might even favour clevis pins and R pins, if you want to make it
easily dismantlable without tools.
Should weld easily enough - it's one of the few DIY tasks I can
imagine where a stick welder would be useful, not just a MIG.
Personally I'd MIG weld the frame into flat panels, then bolt or pin
the rest. Even a large flat panel is easier to store or move than a
small 3D object.
Yellow pages - anyone local ought to do it. Steel stockists are
generally helpful about small quantities of common materials, so long
as you either collect or can wait some days until the truck is in your
