Bludgeoned a steel swingset A frame joint onto a 6x4. Poor fit. Did last 4 inches using the backside of a splitting axe, metal on metal. Bent the heck out of the lip, but got it on far enough at last. Wouldn’t have made it that far if neighbor hadn’t lent me a belt sander to reduce size of the wood beam once I was partway on and could hammer no further.
Took a couple ibuprofen. Hands already swelling. Last time I did something like this it was chipping an outlet out of brick miner style - hand was sore for a few days after. But darnit I showed that bracket. >.>
