Tub/Door Bracing When Taking Body Off

[addicted2dunes]

I know, I know, it's probably been talked about before. Trust me, I use the search feature but came back empty.

I have seen and know a lot of you are bracing your door area to keep your tub from flexing when taking the tub off the frame. I was wondering what the best way to do this is and prevent tub flex? Also something that is easily removable, welded is fine as long as it cleans up easy. My thoughts were to make braces that bolt into the hinge pocket area and bolt to the door latch location. Has this been done? Who all has pictures of their non flexing ideas?
