Then I cut both the aluminum and steel parts to length with a hack saw. The hack saw is very inaccurate when cutting a tube. I left about an 1/8th inch extra when cutting. I then squared it up on my bench sander and sanded up to the line and then rechecked the length.
I flushed all four tubes with MEK substitute to clean them out and then sprayed primer from both ends and rolled them around.
First collect the parts

Leave some margin and finish with the bench sander
