My FIL had a wheelbarrow with broken handles and him being a bit of a skinflint he ripped a pressure treated 2 x 4 in two and bolted the pieces on. IT was amazingly uncomfortable to try and move loaded as the square edges bit into your hands. After a few years of outside storage they warped and twisted make it an even better tool to try and operate and poke fun at. Every now and then when the FIL, BIL and wife are altogether someone will bring up the wheelbarrow and the laughter begins

Your In-Laws and I may share some common DNA. I have dozens of stories like that from close and extended family members. Evidently, WWI, the Great Depression, and WWII did not force much evolutionary change in my family tree.
Only thing more fun than watching one of the Old Timers butcher a fix, is getting a few of them together to brainstorm the fix and then argue about whose idea is the best and whose idea is the dumbest!
Your In-Laws would not belong to that legendary tribe known as Pennsylvania Polocks by any chance, would they?
Tell your FIL he over-engineering that "fix." Couple two inch diameter Locust saplings and some hose clamps would have done just fine.
Tell your FIL he can call me next time he needs some help!
