The two Hitachi 870 excavators is are some of my favorite models in my collection: a superbly detailed 1:50 jewel of a model. As great is the model is, I wished that it came with a quick coupler to make it even more of a versatile model for fitting hammers, buckets, etc. Since I had no luck finding a ready-made coupler, I tried my hand of scratchbuilding one.
A few afternoons work, first reseaching the 1:1 item on the internet, then using that information, I went to work. Here is the finished item, prior to painting.
Sometimes doing little projects are just as satisfying as doing a major one, that adds just a bit more functionality to a model. I plan to make a few little attachments for these models.
