Reading a tape measure...again
After 3 major measuring screw-ups this week I put 3 employees on notice that
they had one month to learn to read a tape measure or...else. They are 60, 55, and 45 years old. How they got through life so far is beyond me. I have tried to make go/no-go gauges for everything but this basic skill is still needed and I can't be everywhere. I know I've been down this path before and I'm so embarrassed that I still haven't been able to teach this on this level. I have yet to find instructions for tape measures. I only want 1/16" accuracy. Any thoughts? |

how far off did they miss by? you sure the tape measure they used was even
worth a crap? some tools like tape measures wear out and should be thrown out. get some stock then give them a test using the tape measure they used, if theirs shows a different measurement then toss them and let them use yours.

There are several tape measures made with the 1/16ths marked. I bought one
for one of my guys. Here is a site: http://www.neboproducts.com/tools/vi...y=2&pid=120209 I have also had to say "one little mark under 3/4" . "Tom Gardner" wrote in message ...

If they already have glasses, teach them how to clean them. If after these three steps have been taken they still cannot read the tapemeasures, I guess it's pension time. |

Had an uncle build a 65ft steel hull boat in his back yard. To cut down
confusion he would say something like this: "cut it seventeen,eleven,seven" That meant seventeen feet,eleven inches, and 7/8th of an inch.Worked pretty good with few mistakes. |

I would say to some one that didn't work in metal that tape measures are for
carpenters and the best you can expect is 1/8" accuracy. That being said I use tape measures often to rough cut bar stock, so I have given some thought to this. Accurate tape measure lay out has two issues, accuracy and lay out technique. Accuracy A tape measure is a step above a yard stick in accuracy. The tape measure has a hook that defines the point that the measurement starts from but has big fat lines that define the increments of measure. The typical tape has as it's finest division 1/16" (0.0625). You are asking for lay out at the absolute limit of accuracy of the gage supplied. Technique Okay, so maybe you want +/- 1/16" That is reasonable, 2x limit of accurate measure, but how do you mark the measurement? A pencil and by eye? Where does the scale define the point from which the measure should be marked? If you use the scale on the tape, the division lines are ~.02" wide and use a blunt marking instrument will be a problem. An imprecise scale and an imprecise marking tool would be for me with my eyes at my age ( 50 ) a problem if there was pressure to hurry up and get it done. My solution: I am a big fan of the Starred digital tape measure. It reads to .05" in inch and 1 mm (~.040") in metric. It calibrates the point of measure, from the hook to the body of the housing, well enough for me, I find it to be about accurate to .025" and .5 mm (~.02") ymmv. That covers the issue of accuracy As to how to lay it out... The problem with a tape measure is marking the point of measurement. I use a shop square to determine the point of measurement, defined as the distance from the hook to the body and make the mark with a sharp point. hope you don't fire anyone Kent Where in Ohio is Ohio Brush?

Tom,
Please consider that the fault may be in the procedure. It is common that there can be in excess of .25" from tape measure to tape measure. If you then add that to different individual techniques and marking methods, you can have unacceptable error. To have one idiot in a group is plausible. To have 3 idiots in a group is possible, but highly unlikely. Establish the standard tool and the method of measurement. Steve "Tom Gardner" wrote in message ...

I only want 1/16" accuracy. Any thoughts? If they are about a 1/2" short then the tape is hanging up where the tab is loosely rivited on. They need to double check that every time , not half the time , every time they mark something. Sometimes you need to start f-ing throwing the scraped parts around the shop to get their attention , even if its just an act. That or just tell them that they just might not get their check on Fri. and go ahead and call the cops. You could try this , some/alot of people don't understand this. 1/1 = 1 2/2=1 4/4=1 8/8=1 16/16=1 1/4 is only one of 4 to one. 2/4 is half way to one or can be reduced down to see that its 1/2 or one half of one. It might not be worth going into about say 5/8's is 1/2 + 1/8 if they don't understand how to change fractions so they look like they see. I would make up some huge one inch scales and give them 5 to take home and study. And a number of examples of how to find say 13/16's without counting thirteen itty bitties. Give them some home work so they can manipulate the fractions like 8/16's , 4/16's , and 9/16's so they can come back with different examples of how they can be perceived. Like how many quarters plus how many eights and how many sixteenths does it take to get X . After they get that then and only then have them do the home work backwards , like how far under 3/4 is X. My problem is that I'm too cheap to toss my tapes and hunt all over town to find one that is marked right. All the ones I run across have the lines the same length which just drives me crazy while baking in 130 heat or freezing or windy and my hair getting in the way. I've been reduced to marking the right spot with a sharpy and trying to wipe it off when I'm done. Hey, it took me about 3 stores to find a magic marker ! I had to bitch about how a hardware store doesn't carry cement or magic markers to a hardware store to find out that they are called sharpies now. Kinda like asking for real to real tape , "real tape?" That took about 15 stores to find. That reminds me , I need to see if those old sealed tapes are good or not. Good luck... There are alot of people that don't understand fractions. Maybe they make mechanical scale tapes ? Metric, I don't know , never really looked at that side. My wife always makes too much to eat ( great cook BTW) cause she doesn't know what half of 2/3's is. ) I'll look and see if one of my books explains the scale in a neat way , but I don't think they will. |

Feet, inches and eights is the traditional method of marking distance on
the table of offsets that describes the hull shape. In the lofting floor a reader would call out "Plus Ten, three,five,plus " and the lofters crawl to the next station and measure up 10' 3 11/16" from the waterline marking the point. Now days the computers spit out instructions to plotters in some unknown language to turn out mylars. Mike wrote: Had an uncle build a 65ft steel hull boat in his back yard.

Can't help with the problem, but I do have a good story that's barely related..... ;-) Told to me by an 80 plus year old machinist --- seems many years ago he was given a drawing with exact specifications for a very important part. Spent a bunch of time making it just right. The part fit in a socket on something near the ceiling in a high-tech installation. Since he'd built the part, he was carried by crane way up to put it in. Men in white lab coats gathered below in anticipation. But the part was a half-inch too big and wouldn't fit in the socket. The machinist yells down to the ground with the bad news, causing a white-coat huddle to discuss the problem. They finally reach their decision, and holler up their plan ........ TRY IT AGAIN! The old guy told the story a lot better than I did here, and I was in tears when he got to the end. Wayne |

Since we are on the subject of tape measures....what do the diamonds
reference on the tape? Dominick, The diamonds are for framing walls. Standard walls are on 16" centers. You can use the 19" 3/16 diamonds on non structral walls.16" = 6 studs per 8' wall 19" 3/16 = 5 studs per wall. If you are framing 1000's of feet of walls large savings Remember the early bird gets the worm, BUT it's the second mouse that gets the cheese George |

They need to double check that every time , not half the time , every time they mark something. Typically a framing crew will cross check tapes at least once. If it's a problem with the tape measures, have a steel ruler that they can check the tape against where ever the tapes are stored. I could have sworn there is a 1/16" marked tape or ruler out there. After some digging, I found Woodcraft has a steel ruler marked with 1/16 but most are marked 1/64ths. And before anyone says they're all marked with 1/16s I mean it actually has the 2, 4, 6, 8, 10, 12, 14. Then you could tell the guys 4" and 12 or such. www.woodcraft.com But I looked at the photos and they're too small to make out the detail like the catalog. Ok, here's a tape measure that has fractions printed on it: http://www.asktooltalk.com/home/general/ultimate.html Ok, that might only have 1/8s I found a better pictu http://www.brucemedical.com/eastoreadlar1.html I found several sewing tape measures which only have the 1/16" lines on it. (yahoo search on "tape measure" large numbers) You might try a teaching store I believe ruler was taught 2nd or 3rd grade. They should have materials. (yahoo search on 'reading a ruler') http://mathforum.org/library/drmath/view/58333.html http://mathforum.org/library/drmath/view/58439.html ('how to read a ruler') http://www.woodzone.com/articles/Read_A_Ruler.htm http://www.rickyspears.com/rulergame/ If it's fractions they're having trouble with I'm sure some searching would turn up some good sites.

For jobs where you can afford mistakes, the person who makes a certain feature a certain size, records the actual measurement on a second drawing supplied with the job, or an "inspection record". Yes. All of these (well, with the possible exception of the 'metric threat') are excellent ideas. Most shop require critical dimensions on finished parts to be personally accountable to one operator. Where I used to work at night, each part had five or ten dimensions that were toleranced, and every ten parts every one of those had to be measured, and written down, and initialed. Some of this stuff was +/- 0.005 mm btw. In nylon) Because most of the jobs were long enough, they outlasted a shift, and the new shift coming on would immediately double check the outgoing shift's measurements. The most important thing for managment to do when dealing with metrology issues of any kind is: 1) provide accurate, calibrated measuring tools that are 2) easy to use and simple to read. 3) identify those who cannot use them and either 4) train them, or 5) remove them from jobs requiring measuring. and most important, foster the concept that the MOST important thing is not ship out-of-tolerance parts. There has to be an enviroment where anyone can call out wrong-sized parts, and be sure they won't get yelled at. Where I used to work, even if a guy worked all night long making parts, and on the *last* one, realized he did the previous 500 parts with an incorrect dimentions, he KNEW that it's better to call the foreman and leave a note, rather than try to cover it up somehow. Call and say, 'hey I screwed up' was met with a much better reaction than if the outgoing inspection revealed the problem, or heaven forbid, they missed it, and the *customer* called and said - "hey this stuff don't FIT!!"

Reading a tape measure...again

brought forth from the murky depths: Been there, done that. How about the new guy hired to run the main cut off saw. A week later we discovered that he did not know the difference between eights and sixteenths. We lucked out, he only cut a couple orders short, those were rough cuts for blanks and we could salvage all of it. Whew!! Anyway, my suggestions: 1) Go through the shop and replace ALL the tape inserts (yours and employees) with new ones with sixteenths marked. The inserts are cheap, buy them by the dozen, replace every 3 to 6 months. Forbid any non standard tapes to be in the place. Also, check each tape against the rest. One of the woodworking mags had an article a couple years ago about the nasty inaccuracies of tapes, even within a given line. I couldn't find it this morning. 2) Since it was the older guys that screwed up, send them to the optomistrist for new glasses. You might also have to put brighter lights in their work areas. Ask me how I know this! Having just bought 2 new pairs of eyes, I can totally relate. -------------------------------------------------------- Murphy was an Optimist ---------------------------- http://diversify.com Comprehensive Website Development |

Post a big one on the wall, smaller ones above the cutoff saw and other critical spots. The graphic should have ALL 16 marks shown as eg 3/16, 5/8, etc. Even better would be to have all the major ones specified as 3/4"= 6/8" = 12/16" 4) Be prepared to downgrade (not fire) someone who does not try to improve. 5) Peer pressure also works. I had a major screwup that was only noticed after plating and shipment to the customer. Flaw was not reworkable. Had the parts sent back, dropped off in the CENTER of the shop, near the break room. Assigned the guy who drilled the parts wrong to unpack the crate, unwrap the shiny parts, and pitch them in the scrap dumpster. Took him a couple of hours. No yelling, no screaming, just a 'standard' assignment. Only mangement comment was "parts had to be scrapped because they were drilled wrong" You better believe everyone in the shop knew what was going on. And the offender did not get much flack in the break room, no one wanted to be next on that list! Good luck, you just have to keep on it. Cheers.

Along these lines a funny thing happened to me one time. I was cutting
some plywood for lids on some woodenboxes. Measured the boxes with tape at 16". As I was going to free hand these on a table saw I needed lines to cut to thus a straight edge. Grabed an old scale that had been hanging in the outbuilding when I bought the place. Used the scale to measure and draw the lines and proceeded to make the cuts. Put one on the box to see how the fit was. It was 1/2" too long. Anyone except a few old timers know what happened? The answer is below. The scale was a patternmakers scale with a 3/8" shrinkage allowance built in. Chuck |

In article 091120031107350638%pilgrim6__spamfree__@mindsprin g.com, Pilgrim
says... The scale was a patternmakers scale with a 3/8" shrinkage allowance built in. The same effect was documented in a book called "On High Steel" where an apprentice (all apprentices are required to carry *some* kind of measuring device with them on the job) always cut stuff the wrong size. Finally one of the old hands said "Let me *see* that thing" and it turned out to be a shrink rule! Great book BTW.

We finally took all the shrink rulers and wrapped them in tape to warn folks about this. -- Roger Shoaf If you are not part of the solution, you are not dissolved in the solvent. |

Tom,
I'd suggest making their pay proportional to their accuracy :-) 10% for every 16th off. Bwooohaaaaaahhhaaaa (evil laugh) 1) make sure they're properly equipped with good tools first 2) If your stuff is repetative make a "story stick" and work off that It's hard to find good help Tom "Tom Gardner" wrote in message ...

It sounds as if you are being very fair and perhaps too lenient.
Rickover had a policy that everyone working for him had to be taking classes. That might be more than you can justify, but I certainly think you can require employees to take some classes. You might also require all prospective employees take a basic skills test. Many years ago I interviewed a young lad for a job that did not require much skill. He had a high school diploma and I gave him a tour of the plant and asked if he would have any problems doing various things. His answer was always that he could do it. But somehow I got suspicious and started asking questions that needed an exact answer. I found out he could not add fractions, and then that he could not read a tape measure. And as low tech as we were, we just could not afford to hire him. Dan "Tom Gardner" wrote in message ...

brought forth from the murky depths: Just how many "Bittys and itty bittys" is that? Ask Vern Nier. He knows about those things. Tom: Larry's on the right track here. Send them all to classes to learn how to read a vernier scale. If they can get through that, they should be able to handle a tape. Not to say they won't ever make stupid mistakes, though. We all do. I do, anyway. "Measure twice, cut once" usually works, if you add, in between the measurements, "go to the bathroom, have a smoke, go out and look at the sky, tell somebody a joke or read the newspaper, then go back and measure it again from scratch". You could always take the hardass approach. Make 'em buy their own tapes. After a mistake, ask to see the tape. Say something like "Gee, Bill, here's the problem. It's not your fault. Your damn tape is no good. Hell of a thing when a bad $15 dollar tape screws up a $500 job." Then pick up a pair of snips, cut the tape, and tell him he should get a new one. John Martin |
