BarryH, I have a welder, I wish I could weld. I just read the book.
Hopefully this is my last set of pictures for this attachment. I expect everybody is getting tired of the updates.
I noticed a little tilt. Other than that it looks good. I had some friends stand on it to demonstrate its strength. Their total weight is about 330 pounds. I cut their heads off because that would have been too much weight. I also put my 250 pounds on one side (not at the same time as theirs) and there was very little give.
Thanks for all of the interest, support, and advice. This make for a much better attachment.
