Martin, that is excellent advice. I take the promise (from customers) of great wealth and ton's of work -with a tongue in cheek attitude. Although, I do like your livery idea. Typically, I try to cover my development costs, equipment costs, and a small profit up front.
As far as the discussion is concerned, this has been a very interesting discussion and I don't think it is over with. I lot of good ideas have been exchanged. For example, Dealguy11 introduced the idea of vibration creating chatter. I dismissed the idea initially, due to the fact other projects did not seem to have the problem. DealGuy11's comments made me rethink the idea and I think I will create a series of sin curves and put a slow-motion camera on the bit to see if I can detect any vibration.
The recommendations of garyb also intrigued me. I'm not sure I'm going to spend the dollars to get the onshurd 66-700 bits. My friend Jim thinks someone misplaced a decimal place on the price, changing the price down from greater than 1500 dollars to under 150 dollars with discounts. Another key point (in Gary's discussion) was increasing the number of flutes to 6 -10. After a little research I found the following article:https://www.woodworkingnetwork.com/best-practices-guide/cutting-grinding-cutting-tools-grinders/how-rout-clear-edge-acrylic
So it looks like I might have some fun and go back to the shop and run some experiments. You never know, the customer might be serious and have that kinda workload.
