Shop crane is making progress, uprights trimmed and welded to base, drilled a couple holes and next is drilling/mounting the boom. Cross bolt is too short, will have to hunt something up that will work.
The taller heavier verticals will make it so much better, and in all likelyhood i should have no problem lengthening boom.
The standard folding shop crane is about 18” too short to swap engines in newer gm trucks.
