Well Mike, Ted says those prices are in line with what's expected, at least one person expected that, so if the market will bear it, more power to you. I wouldn't pay more than my bars which would top out around $100. Just my two cents.
Those shims would take me about 3 minutes to figure out the math on the angles and 15 minutes to set up (rotating the head on the Bridgeport, moving over a vise and clamping it down to the table, digging out the parallels, end mill, collet, etc), and I'd be cranking them out in 20 minutes or less each. $70 each is about what I'd charge if I was the shop charging $140/hr. But they don't pay me $140/hr.
Also, the assumption is, you're using those shims for work. Either you sell them to customers in need, or they help you do your job. Either way, they make you money. Unless I were trying to make a custom saw for resale, bar decoration isn't making me money. So coughing up machine shop rate is a hard pill to swallow since it isn't a "need" but a "want".
Yes, 4 coats of blue for 15 minutes is an hour, but would I pay you $100 (@$100/hr) to blue my bar nose? Heck no. I don't pay my painter for the time it takes the paint to dry either.
--edit--
I'm also very confused about the concerns with clear coat and/or wax to protect the finish. Almost all bars come with a pretty decent paint job that wears off in a few hours use. Only Total/Tsumura and SugiHara that I know of have a visible metal finish, and their clear coat wears off just like paint. [The bars are going to get roughed up in use people, it's normal. Eventually it will be bare metal. ]
For those people that don't like bare metal, or having a half-removed paint job (for shame! Lol) I get that you could appreciate engine turning as an aesthetic design choice that won't rub off. But then to worry about the durability of such a finish again and go back to trying to paint the bar seems like two steps forward two steps back.
