Bore and broach
I would like to have 8 of the following parts machined. You provide the stock. I would like a quote for bearing bronze, and cast iron. I would like this part made by early May of 2008.
I am uneducated on tolerances for bores and keyways, but whatever they use for standard pulleys is what I would like. Thickness of 0.5" +0.05"/-0.05", 2.000" dia +0.05, -0.000. Thank you to all who consider these parts for me, Rob |

How tight of a fit on the bore? To get a really good fit and finish, it will have to be reamed.
Do you want both sides faced or just left rough after parting? |

Faces can be left rough after parting. Yes, reamed to 0.750 +0.001/-0.000 would be great.
Bronze hollowbar (932), 2" OD, 0.75" id, 13" in length is available from onlinemetals dot com for about $87. This would be a great starting point. |

You can't ream a hole the same size as the bore ,it has to be undersizes by at least
1/64",so bore needs to be drilled/bored to .734375 aprox Is 932 the alloy you require? |
