How do I bolt to off axis spacers?

[Philipintexas]

I have a need to bolt a plate to 4 cylindrical spacers that are not perpendicular to the plate. The drawing shows the ideal solution using counter-bored recesses but it's not practical as it would require a 3-axis machine or several additional manual operations. I'm aware of spherical washers but they're cost prohibitive and don't work at this angle. An angled cut to the top of the spacer isn't practical for several reasons. The volume is high enough that manually drilling/counter-boring would be costly. Is there a solution I'm missing?

Couple of taper washers would do it, the type used when bolting to the flange of structural steel I beams and not costly.

You are not giving much info, while dismissing ideas that have merit without figuring the actual cost. Dimension would help alot as well.

But heres my idea, only 8° angle, I'd angle the head of my BP 8°, spot mill spacer side , and pop a hole at the same time, flip plate over now using the hole to center spot the flat for the bolt.

If you can't tilt the head tilt the part.

Second idea, take washers place on grinder, set angle make all the same.

Third idea, a hack fix, drill a rod the size for the bolt. set the saw to 8° cut off to about the same length, install.

I always try for at least 3 ideas to address a problem, then as you look at each the best tends to emerge.
