I've now finished most of the trusses think I want to rebuild 1 more to have 5 that wy I will put them on 15 ft centers instead of 20 ft.
So I need to make 1 more like this one.
I made it double but also added spacer between the 2 halves and extra stiffeners this is in case later I decide to hang a pair of beams below them for the rails of an overhead bridge crane. It is so stiff I can carry it flat from the center and it does not have any bow to it.

Since I had another project to do that required me to change my welder over to the duel shield flux core wire I decided it ws a good time to build the Southwest corner column while I had the heavier wire in my machine.
I had an old 36 ft step deck trailer that I built back in 89 that I have been wanting to convert back to a 24 ft gooseneck so I cut the heavy upper deck off to use the main beams as part of the column in the shop to mount a brick crane on top of
This is how the corner post turned out.


To plant the post I dug a 8 ft deep hole 8ft by 8 ft
Here I am packing the wheels with slightly moist clay and portland cement

Now back filling the hole in 6" layers then running my plate compactor on each layer which packed them down to about 4 inches.

Many layers later I have only a few feet left to go
