If you'll go to my blog (bobhooversblog.blogspot.com) and enter
BURETTE as the search seed in the little white window in the upper left of the screen, you'll be presented with an article with the same title as this message which explains what's involved in adjusting the volume of your combustion chambers. Like most of my articles, this one has generated the usual rants from the guys who have built a million engines without using any of the procedures I've advocated over the years. The funny thing about those procedures is that I'm not the guy who dreamed them up. All of these procedures, in whole or in part, can be found in the Factory Workshop Manual from Volkswagen. All I've done is 'translate' the procedures by describing how I did them, or described how to make the tools needed to accomplish them. This particular article, having been written in the late 1980's... back when I was doing everything with film and the drawings in pen & ink, appears on the blog without any illustrations at all. The supporting illustrations had to be run through a scanner, then adjusted for contrast or color balance, then cropped to fit a particular 'box' in the Adobe file, then.... on and on and on... As you can see, it never got done. That is, the book of which this was to be a part, never got written. Nowadays it's so easy to snap a digital image and insert it into a file, I'm a bit ashamed for nor having done so with all of these older articles. But there's only so much time in a day and I somehow manage to burn it up without having completed all the items on my 'to-do' list. For some, the printed word simply isn't enough. They need to SEE how the procedure is done. So I will try to insert enough graphical information to get you started. One thing that many find to be an obstacle is the plastic cover- plates. Others have trouble tracking down an accurate burette. And more than a few don't have the rotary tools needed to ENLARGE the combustion chamber. That's all you ever need do, you know... make the LITTLE chamber(s) bigger. And as with computing Compression Ratio, you are not required to do all FOUR chambers nor cylinders, you must simply adjust the THREE to match the ONE which is of the proper size... or as near to it as you care to go. -Bob |

Everyone, Please ignore the rest if you like (well you will do that anyway - ignore it if you like ![]() For how long has combustion chamber volume balancing in the US been based on the metric system? Whatever happened to CI'ing? I'm in the UK and I am pretty sure I have never seen a non- metric burette, starting from school in the 60's. By then school science was all metric. I did an advanced mechanics course that used Imperial units in my last year but that was exceptional - and somewhat confusing too. Slugs, poundles - IIRC. |

Combustion chamber measurement for Chrysler engines in the 70s was in CCs (or mL probably more correctly). |

![]() For how long has combustion chamber volume balancing in the US been based on the metric system? I don't know either, but I only heard this part of blueprinting described in metric terms in the early 60s, when I was in high school. Peter |

For how long has combustion chamber volume balancing in the US been based on the metric system? ------------------------------------------------------------------------------------------------- In so far as I know, just about forever. The United States was one of the first nations to advocate the use of the Metric System (in 1866 -- looong before GB, by the way). Congress re-affirmed our 'Metrification' in the early 1950's and AGAIN in the 1970's, but the American Congress being the best government money can buy, while our Legislators established the Metric System as the law of the land they provided NO FUNDS for the conversion to metric units, nor any penalties for failing to adopt the standards. The Library of Congress was the only entity directly effected by the adoption of metric standards, they asked Congress for the necessary funds OR permission to have the law set aside in their particular case. The exemption was immediately granted and the pattern for that exemption has since been used for literally hundreds of other agencies and corporations. You really gotta love them politicians :-) For the past sixty years our vote has not gone to the man who can do us the most good but the one that does us the least harm. -R.S.Hoover PS -- Whatever happened to CI'ing? I donno. Ask whats-his-name. |

Although he wrote several good books, and was a very popular columnist for Popular Mechanics and Circle Track magazines, his "Smokey Yunick's Power Secrets" alone was a very good primer for the type of work you touch on here. While a bit expensive for the every day automotive overhaul business, I have always wondered why some of these techniques were not standard in the aircraft industry. What kind of problems do your readers report with plastic cover plates? |

The exceptions have to do with plate thickness, cost and so forth. One asked if GLASS would be okay. I rogered that, asking him to provide pix. Got a couple of B&W's . He apparently used the tempered glass from a grocer's meat locker. -Bob |
