While I did get it down to my shop, I found my bench was too small to even attempt to keep this thing flat and square, so I took it down to the shop where my son works and they were kind enough to let me clamp it to one of their big benches and my son welded it all off for me. I'm pretty sure I used most of the clamps in the shop to hold it in place while the welding was done.
