All look perfectly nice and clean, good work. Just want to remind you something which you will have problem with.
I am the one of the first dust collecting shoe designer for X-Carve. In very short period of time, we all realized that, if Shoe attached to router, Z accuracy is changing badly when bristle hits the work surface. At least Original Acme screw type up and down moving mechanism with V-Wheels. That’s why most of us switched to stationary attached height adjustable shoe.
Best example for that is Suck-It dust shoe. You may consider before too late.
Thanks for the kind words and the caution. I really appreciate it. I will do a lot more digging up into the post. I don’t mind redoing and re-engineering. This is a wonderful tool and in the middle of this I find myself carving all sorts of this and that. And in the experimenting I’m learning and having fun.
