Very well-done, IMO!Here is an image of the plastic handles that I did to take out to site nothing special unlike yours, the top one was sawn to octagonal the rest went through the planer.
I made two sets of London pattern in wood that I sold on when I stopped work I have some images of those but cannot locate them at the moment.
I have never worked plastic in this manner. I have sawn plastic, but never planed it. Any special precautions?
I may want to give that a try!
