I have about the same tools as you do. Well not a real mill, just a
drill mill. And I will probably make a wood model or two. I do have
plans but am not sure how good they are. And do have a real backhoe
not too far away that I can look at. Your front end loader convinced
me that it was possible for me to build a mini backhoe.

===========================

My Clausing is about the same size as a mill drill, ie the table
wasn't long enough to drill two parallel holes several feet apart. You
won't have the problem of trying to make both sides identical and
aligning their pivots, but the horizontal pivot may be difficult
because so much force is concentrated on it and its height may need to
be more than your mill's quill travel.

I quickly found that shrinkage prevented welding pre-finished parts
into a complex assembly. Whatever precision machining was needed had
to be doable on the fully completed unit, meaning I had to include
reference surfaces and provide for clamps.
