Here is the next phase of my new 'Heavy Duty' 12" tube rings.
Below is a pic of the parts ready for welding tomorrow.
On the left are the hinges. I searched Ballarat for the right hinges but had no luck finding 40mm wide 'Heavy' hinges, so I used the one I had at home and cut it in half!
On the right are the bolts and wing nuts for the locking system.
At bottom is the mounting brackets for the locking system. It is a car exhaust U clamp base cut in half. These will be welded under the flanges with the bolts drilled and pinned into them so the bolts can pivot up into place.
Keep watching this space for updates
Hmmm, they look smaller in the pic than they actually are!
