Here's my current welding practice piece, made out of 1.4mm mild steel.
Having the new bench shear now allows me to cut effortlessly through this gage metal, so the thought of making a Tetrahedron came to mind.
Perfect TIG practice and a great first job for the shear. It is certainly no easy task to tack the the shapes together once they've been cut out, holding the dam things was the problem, got there in the end though.
Next step is to finish weld all the joins..... watch this space. Did I hear someone mention gilded pin striping to finish it off?
