5th Point Belt Attach Fabrication Question
I need to get the 5th points of my harnesses installed. I have a 6A, so figured I would fab the parts, as the Van's kit may not fit well given the potential tolerance drift on the 6 series. Seems pretty easy to make. It looks like .032 or .040 stock. Can you anyone help me confirm the sheet thickness. I have .032, but no .040 stock.

Going from memory I think it was 0.040. I can check this evening tough. I used the kit for the -7. I have to cut one ear off and rivet on some angle, but it wasn't a big deal.

Also used the -7 kit for my -6A
The passenger side fit pretty well, had to do some modification to the pilot side. Glad I did it.

I just measured mine and they are 0.040" thick.

I used the kit from Van's on my 6A. It fit well with no modifications.

I bought the Van's kit for the 7/9, then gave up on it. The web on the ribs of my QB fuselage where not flat, they where quite bowed, and they where not square to each other, not even close. Even after shearing the flange off one side, it was still a poor fit. I have one of the first QB 6 fuselages and it shows.
I ended up fabricating my own using .063 angle for the flanges, but basically copied Van's design.
I was glad I bought the kit even though I didn't use it. It was inexpensive and a good starting point for engineering my own, but it still was a big job, much bigger than it should have been.

Thanks for the help here guys. I ended up copying the design that Pat Hatch used and formed the parts in both .025 and .032 and riveted them together as I didn't have any .040. Pat's design is an overlapping of two parts, making fitment easier for us 6 guys.

Does anyone know what thickness the Pat Hatch (Schroth) overlapping supports brackets are? Are they 0.040 or is that an estimate?
It looks like the easiest solution for a -6 to me.

THey look like .040 in the picture. I couldn't find a reference to the size anywhere. I figured .040 should be adequate. I am not counting on that strap to keep me from submarining, just to keep the shoulder straps tight during turbulence.
.063 seemed like over-kill. The webs they tie into are only .032 or less.
