tolerances question
This is actually for a 944, but there is much more action over here, and is an interpretation of the specs in the manual. In the manual it lists runout, diameter, out of round etc. I am assuming these are in MM not inches. Is this correct? And, how do I convert to inches?
Specifically, the crank runout is listed as .04-.06 which I am pretty sure converts to 16/1000-24/1000, or 16-24 thousanths. Can someone correct me on this? |
Donnie,
"She was 25.4 years old, she was beautiful." The guy from Griffiths taught me that and I always remember it. Inches to mm is 25.4. All the specs are listed in millimeters. So crank runout is 0.0016, or sixteen ten-thousands to twenty-four ten-thousands. That is not easy to measure but it can be done. If you don't have access to metric metrology equipment, OK, not a huge deal. Personally I don't think there is any difference in user-friendliness for Decimal-Inch vs. Metric, at least at the level of tool-room tolerances-- it's all powers of ten in either case. |

to convert mm to in.
multiply the metric value by .03937 divide by .03937 to go from in. to mm 4.0 mm x .03937 = .1579 in .1579 in. / .03937 = 4.01 quick and easy Mike Bruns |
Even easier is to Google "metric converter" or some similar search words. There are plenty of free programs which will convert one unit into another. I have on on my desktop. I don't often convert furlongs into versts, so it has a lot of not very useful stuff. But it has all you want. Remembering 25.4 will get you there, but you have to haul out your calculator.
Just do it with a click and some typing of numbers on your desktop. Here is the one I've used for years called "convert.exe": Convert for Windows | Josh Madison |
