Sharing here, this morning I went to get x-rays for my 6 month post right side complete hip operation, healing is on track.
My Titanium pieces are fusing nicely to the leg and hip bone
While in the x-ray room with the door open I noticed how heavy/massive it is, 5 hinges and all.
It's a solid slab sandwich with lead in the middle! Veneer on both sides.
Did not get the whole door profile, but these edge views show the construction, I thought neat.
I told the tech I was "into" HT stuff and would it be ok for me to rap it with my fist to see how solid it felt, she said "sure", as I was there 7:30am 1st and basically empty office. Man it was rock solid dead THUD, no resonance.
Light rap, medium rap, and pretty heavy rap all came back as a THUD.
This does not show the hinge side, but the door was hanging in this huge steel thick frame - much more sturdy than your typical office steel frame, makes me wonder if for the ultimate HT soundproofing effort instead of using a wood frame this should be looked at.
