Barnyard BOb -- wrote: 600 ten thousandths 60 thousandths 6 hundredths .6 tenths.... All the same thing. When talking about inches, all that stuff you wrote equals 60 mils which is a heck of a lot easier to say than "60 thousandths of an inch". Heck, I can't even say the word "thousandths" with any degree of clarity unless I say it really really slow. There ought to be a law against such words. For the record, one mil = 1/1000 of an inch. And yes, Bob, you are surely correct about the 30 mil overbore and 6 mil piston/cylinder clearance.

----snip---- Ahhhh. Swope Farm and Mile Hi Fields beckon. I'm envious, Corky. You're a better man than me. I took a look at the pictures and prose earlier in the thread. Swope farm didn't look too bad since the 134 foot elevation change is worth a little more than 50 knots, by my calculation, that the engine need not contribute; although you'd better be ready when you're ready. On the other hand, I'd rather just watch mile high from a safe distance; or better yet, not in "real time". Peter |

wrote: Could you possibly mean... .028 .030 28 thousandths 30 thousandths Barnyard BOb -- My apologies. I don't use a micrometer much and every time I do I have to study and learn it over and over again. I sympathize, since I did use a micrometer for many years. g [Got that... big mouth Latchless Larry?] I meant to say that the cylinders were rough bored to twenty eight thousandths over, then honed to the final size which incorporated the sixty thousandths piston clearance. If that's .060" clearance, then that's what I meant to say. To throw you another curve.... I'm thinking your piston clearance is really .006 or 6 thousandths. Clare or Bruce may be chiming in on this one. g Standard "rule of thumb" for engines you had no specs for was 2 thou plus 2 thou per inch diameter. Which would be roughly 8 thou. Camground pistons were usually fitted a bit tighter. Like about half or less. Factory spec for a 3.8 is 0.0014 to 0.0028 |

David O -- http://www.AirplaneZone.com Every machinist or mechanic I've ever met just calls them Thous. I've heard both used in my somewhat limited exposure to that world. Now if I started saying "thousandths" or "thous" instead of "mils" in my professional work (EE, pc board fab, etc), I'd get strange looks indeed. "Mil" has "of an inch" in the definition which pleases my engineering sensibilities. Along similar lines, before "Hertz" was adopted by SI in the late '60s, most folks just said "kilocycles" instead of "kilocycles per second". Hertz has "per second" as part of its definition which also pleases my engineering sensibilities. A lot of hams, however, were miffed when their beloved "kay cee" was supplanted through a tribute to a dead German physicist. David O -- http://www.AirplaneZone.com |
