Desperate times will call for creative repairs. I broke an old hoe and also had a broken rake. I fashioned the end of the hoe handle to fit the rake as I use the rake more frequently and I can mix concrete with a shovel when I need too.
Using an axe, I roughed the end down to match the smaller diameter rake handle. Fine tuned it with my carving knife. Located and hand drilled the bolt hole. Scraped the new old handle down and sanded off the old weather. Then gave the handle a heavy coat of boiled linseed oil. Bolted the rake head back on and I’m back in business.
