Outside calipers as clamps

Just to keep everything relevant, I made a vernier clamp.🤓

 

For those who like too much information….This particular caliper reads measurements in 1/128ths of an inch apparently.😳 The main scale (ruler) is marked off in 16ths. There are 8 spaces on the “vernier” scale at the top of the movable jaw (8x16= 128) so each graduation equals 1/128 of an inch. The first “0” mark is just shy of the 2-1/2” mark, so 2-7/16” (2-56/128”) is the measurement to be added to. The 7th “vernier” graduation mark lines up the best with a graduation on the main scale (16ths) so 7/128ths is added to the 56/128ths for a total of 2-63/128ths. 
1 divided by 128=approximately .0078x63=.492 So this measures 2.492 by this caliper.

I measured it with 2 other calipers: Cheap Vernier= 2.492” Dial caliper= 2.496”   Digital caliper= 2.493” 

So this cheapo caliper is pretty darn accurate to two decimal places. My brain hurts now, so I think I will stick to my dial and digital units.

You must have gotten a Monday morning caliper. Seems like mine was made on a Wednesday, right after lunch. The one I just bought gradually gets worse, being a 16th off by three inches. Definitely clamp material.

I'll stick to working in millimeters.  Much easier than the old inch system I was brought up on.
