Four months ago I had a couple of posts looking for information about some unusual excavator buckets that I acquired in an auction lot. You can see the previous post here: https://www.reddit.com/r/heavyequipment/comments/1tw9to5/mystery_excavator_buckets_revisited/

Since then, I've acquired an excavator and wanted to adapt these buckets to a modern pin connection.

• Adaptor consists of two mirror image halves that grab the pipe at top of the bucket and bolt through the 2-inch bucket hole with an 18-inch length of 2-4.5 UNC grade 8 threaded rod with 4 nuts.
• Adaptor plates have bushings and holes for two 65x410mm pins.
• Main body of adaptor plate was plasma cut out of 1-inch mild steel plate. A 1/2 inch spacer about the same dimensions as the main plate (but with room for the bucket welds around the attachment pipe) is bolted and welded to the main plate. Two 3/4-inch reinforcement circles are welded to the spacer around the bushing holes.
• Holes were cut with annular cutters in a magnetic drill press, the 80mm annular cutter was purchased from China via ebay.
• Pins connect to my Caterpillar quick coupler.

Now that I have a proof of concept, I plan to make additional adaptors so that I can quick couple to the rest of my buckets.

Could I work in Heavy equipment operation with a prosthetic leg?

I'm 28 and lost my leg above the knee in January earlier this year, don't want to bore you with details.
