It's a great idea. The basic design is good.
I have done a lot of modifications to it.
The thing I like the most is having the cutter arm on a triangular base.
The cutting deck needed sanding.
I drilled out the movable angle setter so I could put a bolt in to lock it to the table.
I had to cut a slot in that groove for the bolt to go through. Box cutter blades are to thick and don't make sharp clean cuts.
