Got out in the shop and made all of the "H" beam pieces.
I used some 3/16 x 2 1/2" scrap I had in the bin.
Laying out the cuts.

I free handed the side plates on my 14" verticle bandsaw.

After cutting out all eight pieces I hit them with a grinder to clean up.

After I got them cleaned up I stacked them together and wrapped them with tape so I could cut all of the angles at once... Much faster that way. I used a milling clamp to hold them in the H/V Bandsaw.

Once the angles were cut I did a quick mockup for welding.

Thanks for looking. I would appreciate any constructive critisizm guys.
