Jim retired and was supposed to take it easy. He lasted about a week. Boredom won, the shed became a workshop, and sitting still was officially retired too.
He makes things out of recycled wood because he enjoys it. That is the whole plan. The sawdust is a side effect. Every piece is handmade, one at a time. No two match on purpose, because Jim would rather follow an idea halfway through than repeat himself.
If you were hoping retirement meant he would finally sit down, the family is with you. The wood was not.
