Last fall I had a thread about cutting edge for a backhoe rear bucket. In the past, I've bought beveled edge from Adirondack Road Materials. They seem not to exist anymore. An exhaustive search came up empty. I could get 5/8 x 6, or I could buy 100' of 1 x 10. D Miller took pitty on me & sold me 26" of what I needed. Today it got installed.
John Deere 410C is bigger than many backhoes. Mine weighs 17400 with my ample body in the seat. The rear bucket was light duty. When I adopted this dinosaur last summer it was Dambodian with missing teeth, a curve in the cutting edge, and a deep crack beside the middle tooth. New edge is wider than original.
Weld in began this morning. Corner teeth are very important, all the stresses in the edge are through these teeth. My son wanted to weld, but I asked for 7018 on these corner teeth. He found other chores.
7018 surrounding these two teeth went well, but it is a slow process. Weld, needle scale, vacuum, wire brush, repeat. It is a thousand step process.
This bucket is light duty, but was used for heavy duty. The walls to floor connection was welded only on the outside. You'd be surprised how thin the steel was! The corners were very thin. I reasoned a heavy multi pass wele in the inside corners would allow for lots more outside wear on these corners. I needle scaled, ground, wire brushed, vacuumed, and blew it off with compressed air. 6010 was severely porous weld
I gave in, set up the Millermatic 252 for Dual Shield. Dual Shield has given me a bad time last time I tried it. Today it worked well!
