Good enough for a home shop for sure.
I've got 3 different sets of gauge
pins, but not a single gauge
block.

Definitely good enough for shop use, but I would do a sanity check on them just the same. After all, they were made in China. Clean them and check them with a good, well calibrated tenth reading micrometer. You should make sure they all measure up to what they say they are before trusting them.

I always found myself using the small set as it was more convenient. Finally sold the large set and never missed it.
I bet you get along just fine with the set you have.
I use round space blocks as much as the jo blocks.
I've got a set of the round ones, too. They seem fine for my use.

Tom,
Really good advice. They came with an inspection certificate so in theory somebody checked them to ±0.000050". The certificate shows them to be in spec.
I have a nice, low mileage Starrett 0-1 tenth mike and I'll be able to check everything up to 1". I'll just have to trust the 2" and 4" blocks but they probably won't get much excercise anyway.

They are Chinese made, Grade B but they are still in the original preservative wrappings. It takes a block or two more to build a stack but this will be a nice little set for my home shop.
This set has a series of blocks that go from 0.1001" to 0.1009" just in case I need to do some aerospace work!
At present I have a 12x18x3 inch thick granite surface plate, a 36 piece set of spacer blocks, these new gage blocks and a surface gage. Next up is a dial height gauge.
Thanks for looking, JScott.
After checking the blocks up to 1" you can wring them and check the larger blocks with a indicator and surface gage on your plate. Its not the most accurate way but will suffice for any hobby home work.

Jurskas, Thanks for the tip. It will help me finish the last check on the blocks. I haven't started yet due to other projects but I will get to it.
