Merk,
I kind of take offense to that. I don't blame the machinist, I blame the tools. If his tools aren't calibrated there is no way he can hit his numbers. I worked as a machinist full time for 9 years while I was getting my engineering degree. Don't be fooled, I am not the typical engineer. Most of those years I was a manual machinist for tool and die and all parts associated with breathable air compressors, we also did a lot of automotive, ATV, watercraft, farm and oil field machine work. Learned to program about 3 years before moving away (and leaving most all my measurement tools behind). Being that I always did my own machine work using checked to standards tools, I trusted this machinist would do the same. By the way I checked the crank and it is .0034 below minimum tolerance on the un-touched journal surface, and about 2 tenths out of round. I don't believe this is a Stens part problem so don't think they are inferior parts, I have never had any issue with them before in normal use or even severe use. In this case I cannot say for sure the rod bore was in spec, that only fortifies the "measure before you assemble" moral. Also, not all internet users are dumb, so please be cautious where you put your emphasis.
The hole in the beam to signify .010" under standard size is universal. This particular rod will end up modified for an insert and shelved for later use.
Plasti-gage is a great tool, it's a fabulous sanity check, you might want to try it sometime to see how accurate it can be when used correctly.
mmzullo, I will not be asking the machinist to make good on this deal. To make it good he would have to buy me a crank (since .010 under is all that is available) or have it plasma-sprayed and risk further damage, I don't see any reason he should do that when I can make it work as is. My old man always told me "boy, if you don't ever mess up...you are dead." Next time I use him I will bring along my measurement tools or just make the trip back home and use the machine shop where the only person there is to blame is myself.
Dobre den.
Justin
