[b]gage block sets; 36pc vs 81pc[/b]

What are the advantages of an 81-piece gage-block set over a 36-piece?
Finding the sizes and quatities of blocks in each set is not a problem.....any supplier's catalog will show that.

But, is it necessary to have an 81-piece set for practical use for any dimension under say 6" ?
Seems a long time ago I read about this subject, but can't seem to find it now.

TIA

Gatz-

In vast majority of cases you will find that it requires fewer gage blocks to build your stack using an 81-pc set, thus reducing your stacking uncertainty. You also will spead out the gage wear over a larger set of blocks. I always felt that the longer gage life obtained plus the reduction in uncertainty more than makes up for the 100-300 USD difference.

Thnx, John.
Was not certain about being able to get the all same gage dimensions in a 36-pc set VS 81-pc set.
Had read or heard somewhere that any dimension in an 81-pc set would require ONLY 4 blocks and that any dimension <=1" would require only 3.
Not sure how that works in a 36-pc set.
Any ideas where a person might obtain (2) new or used .050 wear blocks? The Sherr-Tumico set I have is missing both of them.

If you are in the US, MSC has them on page 1323 of their 2006/2007 catalog for a little over $20 each. If you don't have an MSC account, just about any manufacturing supply hous will carry them.
