I composed my response in my head as soon as I saw G2's post.I was a prototype machinist / designer in the automotive industry for 33 years.
The lowest cost 1 2 3 blocks will work great for any use you will need. The pair I bought for at home was $8, but that was a few years back.
The high dollar 1 2 3 blocks are mostly used in inspection rooms that are temperature controlled and need to be certified to specific industry standards. This would be way overkill for anything we do at home.
I saw them someplace online the other day, didn't know about them.What made you think about 123 blocks Keith?
Thanks, I’m actually no longer at that job. The blocks were used in a clean room, so any coating would be unacceptable contamination, but that’s someone else’s problem now.rydpirs, we us a product called Lano-Lube on inspection instruments.
I guess it is similar to a familiar product to members on here, Fluidfilm.
Lano-Lube is a paste close to a #2 grease. It can be smeared on with fingers or a small brush and a VERY thin coating is all that is required to prevent rust. It works great on thread gages, gage block sets, v blocks etc.
