That has been my point from the start. It's not hard to do. You are the first to admit that reality.I'm not saying that it can't be done or even that it is difficult to do for someone that has the tools and experience using them. Most people don't.You gotta bolt a small vice on the slide to hold the metal blockNow you have moved the goal posts. Most people are not tinkerers when it comes to making metal components.Which part do you think is impossible for the average tinkerer?
You don't think you could put a piece of 1/2" x 1 1/2" x 3/4" inch metal in the vice, adjust the height, and make a few cuts on a simple jig like this? Come on now.

And yet you don’t make one. There's a mountain of difference between looking at a diagram, and making one.
So do it smartass.
