Steel or Aluminum,that is my Question

What post code are you?
That's a lot of freight?
How big is it?

Have you considered bolting the steel together?
No stress relieving needed.

Can you use CAD?

If so draw up some 5mm steel plate brackets for stiffening all the joints put in all the holes as well to form strong corners. And get them laser cut. For 5mm steel the minimum hole size is 5mm.

My guess is a couple of hundred maybe 3 hundred would pay for a lot of brackets inc the steel. Once you are happy with the design glue all the joints together with metal filled epoxy and bolt them up for keeps.

I live in Melbourne OZ

Hi John,
I,m from Cowra NSW 2794 and the heat treating facility is in Brisban.

I was thinking about bolting it but figured you would still need to weld brackets and lugs on anyway which would cause stress.

I use Autocad and I am trying to learn Fusion 360.

Could you elaborate on using epoxy? is that so the plates bolted together just can't slide.
