adapter
In all honesty, to me the design seems sufficiantly odviouse a solution that the idea that nobody had done this before is a bit much to swallow. Three chunks of mass having once been a single piece now held together by six screws and allowing the origional nine bolts to hold the sprocket is a rather simple solution even if dodging the variety of holes is a challenge. The BIG trick is to make certain that the final cut of the center hole, the sprocket mount face and the alignment ring for the sprocket holes are all made without changing the piece mount in the lathe- concentricity as well as perpendicularity of the aforementioned is now a given. That somebody else has a similar idea in production does not suprise me- rest assured that I did not frank the idea from somebody else's work. I do not have to copy anybody else's work to solve a problem- but as I have said before, some solutions are odviouse. Others are perfectly capable of grasping them. If I thought my idea sufficiantly unique as to obtain a patent, there would be no pictures of said device until a patent was obtained. Odviousely this is not the case...
So... in fair answer to your question as to what is the difference- I guess I need to look up the aforementioned Live Fast Motors product and assess it for myself before I can tell you. As to how much it will cost, I need to talk buisness with Chris Bailey at Brewster Manufacturing to find the answer to THAT question... but they will be for sale, I assure you.
