Lighting techniques for flat black products?

Trying to shoot some decent product shots in the shop where I make them. Not getting great lighting. How do you guys shoot flat black?

Warning! This is a knee jerk post....

I think that the shots are overexposed and then the background is eliminated. Seems that most everything black in pictures I've seen is on a white background especially ceiling fans, light fixtures, and such.

I could be wrong so I'm sure to prime a reply or two.

Just adjust it in post...

I assume those are motorcycle parts? Risers for handlebars?
If not, then shot 1 needs to eliminate the bikes in gut BG because you are associating them with the bikes.

Shot 2 needs separation from the background. A light from behind might help.

#3 needs a little fill from the front, and the angle is not terribly appealing. Watch your background, you are showing the edge of the surface plate.

I think a white seamless BG would do well for these.

Yes, motorcycle parts. These pics have had PP. I am finding it to be very challenging to get enough light on the risers to define them without blowing the highlites out.

Get a large sheet of white mat board and take it outside. You can move your shooting location between full sun and full shade to get the light you want. The white board will bounce light up and under the parts. Lay the mat board on a flat surface and bend a curve up on the back half to create a background with no break in it.
