Time spent to draw it.
The only part that would be difficult to machine would be the housing for the glass. I'm thinking that'd require a 5 axis machining center. Along with some creative fixturing.
You gotta either REALLY know your stuff, or, you're still gonna have to know what you're doing and run that program a few times before you get the result you want.
Then figure out which bushings work the best in the arms
Finding out you want the arm 3/8 longer, and the glass 10% taller.
Finding mirror the focal length you want on the glass and having somebody to cut the glass properly and give you the edge treatment/finish you want.
Going to mount them and realizing you punched the holes exactly at 8mm and you can ream them on the prototype, but the final needs to be adjusted in the software.
Running the final.
Painting the final.
Assembling the final.
Making a seal for the mounting surface. Might be something with a part number, might not be.
$1350 is a steal.
I can produce that dollar amount doing my job way faster than I can produce those mirrors. You guarantee a few hundred thousand units, that price can drop immensely with shopping around for shops with the capacity. But I bet FJCO buys less than 50 pair a year, and that's being generous.
Then for me, I don't have a way to mount that style anyways. I wouldn't want to just rivnut the door skin and bolt it up. It would vibrate horrifically. So now I need to have a brace bent up and weld it fore and aft inside to the door frame, and glue it to door skin the rest of the way to make it solid.
"can't wait until someone smashes one of those on the trail" What an awesome person you are.
