    The numbers on this rule should be on the inside. With them being on the outside, you can’t use this rule to measure anything unless it is fully opened. With it partially opened it doesn’t lie flat. Why they make it this way is beyond me.

    This is a 1066D. It is primarily used for its Engineering scale, which is inside-read, which IS on the proper side for it to be used as intended. If you want a Red-end rule (two-way), that can be read flat both left and right, get a 966.

    JH – I’m here for two reasons: One – I’m looking for a product not carried by Home Depot, Lowes, etc. and Two – I’m not afraid of my wife.

    Still haven’t found the product I’m looking for – a flexible rule or tape over a few feet long with all inches broken into 1/10ths and 1/100ths.

    I gather some surveyors would use the Lufkin 1066D but definitely not aerospace engineers and mechanics. They do deal in 1/10ths and 1/100ths for sure but in INCHES, not FEET, no matter how long the measurement (for example – 9.65 inches or 103.40 inches – FEET are irrelevant). Obviously carpenters who normally deal in 1/16ths of an inch would not want this. I’m just guessing, but a carpenter who wanted to switch to 1/10th, 1/100ths, it seems would want a product similar to the aerospace workers or one with both inches and feet with the inches broken into 1/10ths and 1/100ths. To anyone other than surveyors 1/10th or 1/100th of a FOOT seems useless.

  4. as a field engineer i’m always delighted to loan my 1066D to a carpenter–especially one i don’t like, HOPING that he will mark his inch measurements on the tenths scale…sometimes i DO warn him that one side has 10 inches per foot while the other side has 12 inches per foot…over a career i’ve found that you CAN fool MOST of the carpenters ALL of the time…what I’M wondering is–why the hell are you at this site looking for a folding ruler??…if you need one, you need one NOW–not a week from now which is when it will come in the mail…”sorry, honey–the (fill in the blank) project is shut down for a week while i wait for a ruler to come in the mail…oh, sure, i COULD go down to home depot a buy one, but this is SOOOO much easier…”…i’d like to be a fly on the wall during THAT conversation and the following divorce proceedings…no one needs this ruler except construction surveyors/engineers…a novice will almost certainly mark the wrong side, not knowing any better, thereby screwing up a perfectly good board, or worse…an engineer will use no other brand or model–anyone NOT an engineer would be well advised to use a pocket tape and eliminate one more source of potential error…(and, no, you do NOT have to write and tell me that some pocket tapes are marked in tenths…i KNOW that and give those beasts a WIDE berth)…thank you–i appreciate your attention…”measure twice, cut once”…AND–if mama cass had shared her ham sandwich with karen carpenter, they might BOTH be alive today…hey, this is FUN!!!
