Thanks Jim, the subtlety we were looking for..
I took delivery the other day on a set of slide tracks so we used the opportunity to get the Arbor Press metalshaping dies from Pat Brubaker mounted under the table for better use of space. We used the Diacro press brake to bend some 1/8" aluminum for making some angle brackets for mounting.
For those with a Diacro manual press brake, be aware the factory cast parts may not be 100% compatible with cheater bars. This happened a few months back, and our billet steel replacement is holding up much better, still has yet to transfer the problem farther down the line, knock on wood.
E got the holes drilled out in the brackets, and I assembled the pieces..
This is much better.. a good start to cleaning off the table..

.....and then today, Mike and I worked on blocking and straightening out the roof to get it a bit closer for painting.
We did find a stretched spot in the roof, and chased it around a few times in using the body hammer and shot bag. No matter what we did, it tended to still have an up and down wave, so too much metal. The roof has been covered in SPI Epoxy for a while and I had no intention of removing the epoxy, so we opted for the donut dolly (this one home made) as it would leave the paint intact over using a torch....
Part of the difficulty in using the donut dolly is insuring the hammer aligns with the dolly for the most effective shrink.
So we employed our magnet trick seen here:

.......once the trouble areas needing a bump outward were located (they were stretched inward), the magnet was placed directly over the spots and then we could trace the locations on the inside for proper hammer strike while the donut dolly was held over the corresponding location on the outside. This was about the best results I've had using the donut dolly.
Here are a few of the shrink locations used to straighten out the roof and its waves...
