Hello,
I recently bought two H-beam profiles measuring 540mm x 220mm with thickness of the stem - 10mm and 12.5mm top and bottom. They are maybe 50 or 60 year old so I hope there will be no tension or stress left in the material. Are they suitable for mounting the linear guide rails on top of them? Will be there a lot of vibrations versus a square tube for example?

I have also uploaded a drawing example of a weldment which will be used for attaching the profiles to the machine that will grind the top surface to be level for mounting the linear guide rails. Will it be stable enough on only two legs?

Your help will be appreciated greatly.
Best regards,
Peter

Maybe build a mitre box 2 by 1.5 mitre and a gantry with the leftovers, buy a plasma cutter and welder.
