All this information is really helpful! Thank you.
I agree that the polycarbonate base should do a better job of not deflecting on imperfections, which should result in better results, with less effort.
That seems to be why people like acrylic/polycarbonate and are DIYing their own blocks.
My prototype should be here very soon and I can't tell you how excited I am to hold it in my hands and do some testing . . .
And, I'll be incorporating tensioning rods similar to the AFS blocks.
It is a great idea and having the ability to adjust the flexibility of a sanding block vs. having to have several different blocks is a big deal, I think.
I've noted the comments about the rods both coming out and/or requiring force to insert. That will be addressed in my product.
I've reviewed the AFS (expired) patent and my design, in depth, with a patent attorney and we are confident that we have enough differentiation to be granted a utility patent. And when we file the application, this coming Monday or Tuesday, we will have a "provisional" status and "patent pending" and I will be able to share images and details.
While I am patiently (yeah right) awaiting the prototype, I have been working on some branding ideas.
I've seen lot's if pictures of the AFS blocks and some others (Big Kid Blocks) that come in primary colors, like children's toys.
I don't really get it.
Mine will be a black handle and black polycarbonate base plate. In addition to being a serious tool, I want it to look and feel like a serious tool.
Here is my initial thoughts on naming/branding.
Reactions?
