Very well done. You needed extra room around the shop to do that one too.
I have cut some larger things when I had an old Dremel saw with pin end blades; they could go in sideways and I used that trick.
I have considered modifying my current saw to take pin end blades sideways, to get the ability for much larger pieces. I may eventually do that yet, or at least give it a try. Trying to make extra clamps on the blade holders, most likely will not work. But, I have thought about a small straight hacksaw cut just deep enough to hold the blade , with a filed notch for the pin.
