So at last some time for myself.
Time to finish my second build which should work with 1 and 1/2 arm.
I Had the frame sandblasted.
After the blasting some cracks showed up which had to be repaired.

After sandblasting I always degrease outside because I use Acetone.
I needed 2 coats and 2 bakes for this frame.

Cooled down, it’s now waiting for me to start the rebuild tomorrow!
