Well, the company my son works for nixed the notion of me building their stuff. They'd rather pay double for inferior products.. Oh well..
In the meantime I'm working on developing a few other items that seem to sell very well for a few other people I know who sell on Edsy and other venues..I'm also working on a few alternative sharpening products to sell to other woodworking enthusiasts..
I found that I can buy a 6"x2" diamond sharpening stone for about $6-8 all day long, but go from 6x2 to 8x3 and the price jumps to about $60-80... Ten times the price for just 2" more? That's crazy, but it's what they get away with.
Meanwhile I found a company that sells the same type of diamond coated material in larger sheets, but it's not connected to any kind of backing plate so it's thinner and less usable so...I figured I might just capture a segment of the market by assembling the various grits to my own material and selling it for much less than the companies selling for the high dollar. I can get 7x2.5 sheets and get several different grits from 120 up to about 3000 grit for around $6 which I can fasten to a hard, flat surface for much less than $60-80..
Right now I have an order for 5 or 6 grits to test out and if they perform as good as the expensive brands I'm in business.. It hasn't arrived so I'm still waiting, but I'm cautiously optimistic..
