Many years ago I bought spinner components from a place in Oregon. You could assemble the components to mimic a Mepps spinner for about one quarter of retail price. I used them on steelhead and brook trout....worked great.
I also bought spoon building components from a place near Hepworth a few years ago and they worked well on steelhead. I can’t remember the name but they advertised in Ontario Out Of Doors for years.
A finished spoon ended up costing around a buck and a quarter and only took about a minute to assemble.
I think they also had lure bodies. I’ll try to google it and see if I can come up with a name and contact.
Tight lines.
Here’s a couple pics.
