Dave,
Please keep in mind I first started with a concern of safety and suggested you check your equipment adjustments and technic. The arguments and justification of your welds were not my comments, go back through the posts to confirm. I saw genuine concerns and suggested a safety issue, your pictures showed signs of weld undercut, too much heat in front of the weld and concave porous fill. All classic weld/technic problems, I then suggested a weld test. Your idea of a test consisting of jumping up and down on the frame may have been in humor, unfortunately I had no way of knowing you had such dry humor. The thought of someone being harmed (including you) irked my ire.

As an engineer you know this. You also know the importance of safety and safe practices. For you and the public. I'll re-iterate I was genuine in my concern for your safety. If the pictures were poor (which I asked in my first concern), you could have simply posted better pictures. Or you could have said, thank you for your concerns I'll look into it and this would not have escalated.
Nuf said, I'll practice restraint...
Apologies for any insults towards education, not my intent.
