Default Aluminum, cracks from work hardening it

Wanted to share one of my first projects. I have read through half of the basic q's and A's threads,

I'm making a rear pulley cover for my delta drillpress. I chose 16ga 3003-h14 aluminum. I used wheeling machine, tuck fork , stump and heavy blocking hammer, and fsp.






The bottom piece seems trickier than the top. The bottom piece so far, has been tuck shrunk. I annealed once and feel I need to do it again. Two Stress cracks have formed which I will weld repair before I continue tucking shrinking to match FSP. The top piece formed without any cracks. Also need to trim extra material

any advice on how I can prevent cracking in the future?
