Well after I got home from drill yesterday I had some time to finish grinding out the inside of the barrel. I then washed it real good and decided what the hell might as well burn it out one more time.
You can kind of see it but I already drilled the pilot holes for my intakes. Harbor Freight was closed so I couldn't purchase the step bit last night and I wasn't about to spend 50 on one at Lowes. I am bringing home a bi-metal hole saw from work today so I chose the free route. When I get home I'll be welding in my exhaust nipples and putting in the grate hardware.
I also bought some bar stock to level out the trailer.
The green circle is the highest level. I have to add 1/8 bar stock to the yellow circle, and 1/4 bar stock to the red level. This square will be the welding points for the UDS so they all needed to be level. This is going to be welding together this evening. Then once I get all my hardware in the UDS it will be welding on also. I'll post pictures when I finished tonight.
