961 in case (signed R. Moore). Now, hold the thimble and snug the cap with your other hand. Would heating the old sleeve with a heat gun help get it off by expanding it a little bit? Be careful. Bamboo skewers, cotton swabs, and mineral spirits are good for this. Once the screw is out, removal of the thimble is easy. The alignment and size of the bore influences the accuracy and repeatability of the tool. The keyway at the front of the frame. Let me introduce you to the can. A minimal drop of oil on the outer surface near the lead end is all of the lube it takes. Even if it won't rotate, trying will help work in the oil and, eventually, it will probably come free. See details It is not practical to straighten, and regrinding the face to match the spindle costs more than a decent user. In this case, the answer is: on each of ten repetitions of the process at a temperature of 22 degrees (+/-1 degree), the unit zeroed to within the width of the index line. The assemble comes out as a unit, and may require a little finesse. Most likely, the setscrew that engages the slot in the spindle is wedged at the taper-out of the slot. The spindle does not appear to have an end cap, nor is there any visible hole that any wrench would be able to adjust the micrometer. It needs to be able to be moved without being so tight the wrench pin will break. It is NOT a standard screw- it is a tapered seat to lock the anvil position- so it is best not to remove it. I generally use a small blade type screwdriver as a wedge behind the lock ring. If a measuring tool can not reproducibly measure features to the appropriate precision, it needs repair or should be disposed of, as incorrect measurements may be more trouble than no measurement at all. ZU VERKAUFEN! This website or its third-party tools process personal data (e.g. Tactile inspection would include, if the spindle was free, running the tool through the entire range and noting any non-uniform drag or places where it sticks. References. Modern micrometers, nearly all except some digital types, specialty types, and the very cheapest standard types, adjust by rotating the barrel with a micrometer wrench. This can occur even on micrometers in near perfect condition, as over time, even a small bit of moisture or organics getting into the threads will cause them to bind. 07-21-2013, 04:52 AM #6. mikezbitz. Is a Moore and Wright, but in a Starrett storage box! These early, classic designs are regarded as the origin of today's comprehensive range of micrometers, now used in every industrialised country throughout the world. If the adjustment does not want to move, we are back to the penetrating oil and mineral spirits. At this point, final adjustment is done. Since these only get rotated when taking the unit apart, they don't get kept free. Keep going until it loosens up enough to slip off or you have backed up 3 turns or so on the cap. View . The ratchet speeder can be replaced if I want, and, in fact, I have a couple of spares from other damaged mikes. The castellated faces mesh when properly assembled, and by rotating them relative to each other, the free play in the thread can be adjusted. Thank you very much for this. even among different instances of the same model with the same features. To up the ante, the spindle is fully removed from the frame. Yes, your hand produces goo like everyone else's. When a properly sized tool is found, insert the spindle in and press the tool against the missing part inside the thimble.

Moore & Wright 1966MB125 Ext Micrometer 100-125mm . If it won't, it is possible that the the adjuster was swapped from another mic, there is debris in the threads, or there is damage. The position is locked by the screw or speeder in the end. Starrett still supplied them a few years ago, even for the oldest units, but eventually they will run out of the old stock. I don't recall for certain which hole is which (I have a few around and may pull one apart for an instructable if I ever have the time, but I don't get into these too often anymore), but I think this is the one closer to the anvil end on the micrometer (away from the thimble). Founded in 1906 by innovative engineer Frank Moore, Moore & Wright has been designing, manufacturing and supplying precision measuring equipment for over 100 years. The ensuing range of high quality instruments resulted in world renown for Moore & Wright micrometers. If the thimble is straight and concentric, no rubbing is going on, and lines close to zero when the spindle is brought in to the anvil, then it is backed off and the crew given a final tightening. Incorporate all the half millimeters in your measurement. ONLY light machine oil. Moore & Wright 200-01 Ext Micrometer . on Step 1. I would like to keep the original barrel on the currently tight micrometer since in has the tenths vernier but would like to swap out the internal threaded sleeve with the 3 fingers on the end. Did you make this project? You are trying to shock the part loose. No corrosive chemicals. If you drop the screw, good luck finding it. I would not recommend a tool in this condition as a first tool, even at the price, due to the need for significant repair, and the uncertainty about whether it can be repaired at all. If it does, Bob's your uncle. comment. First, lets look at the parts of an outside micrometer caliper, or mike for short, and how it operates: The feature is measured between the face of the anvil and the face of the spindle. Fixing and calibrating a rusty seized Moore and Wright 2 inch imperial micrometer I bought for a pound (1) at a car boot sale!John over at @doubleboost published a series of 3 videos with is friend Bob on micrometer servicing which goes into more depth:See pinned comment for links to Bob servicing micrometers.0:00 Introduction0:37 The first problem0:54 Un-jamming the locking nut1:52 Oiling the spindle thread2:18 spindle freed off!2:39 Removing rust with a soft brass brush3:34 Removing the spindle4:04 Inspecting the threads7:54 After cleaning the threads with brake cleaner8:05 cleaning the lock nut9:50 First re-assembly11:11 Checking calibration12:49 Attempting to calibrate the micrometer14:25 Disassembly to free barrel17:37 Re-Checking calibration18:32 Error in where the barrel is19:00 Resetting the barrel position19:40 Adjusting the stiffness of the thread25:14 Checking final calibration26:29 Conclusion No tools for this. The barrel turned in the holder. The spring between them applied preload so that the screw always bears on the same face of the thread. UK. Unfortunately, you get at most what you pay for. Back out the spindle a few turns by grasping it with your fingers, WITHOUT touching the thimble. No abrasives. 25-50mm . Visual inspection starts with overall appearance. Digital Micrometer Features Range: 900-1000mm (36-40") Resolution: 0.001mm (0.00005") Accuracy: 0.01mm (0.0005") Adjustment rods Ratchet drive Locking screw Zero at any point mm-inch conversion Carbide measuring faces Hardened stainless steel spindle Incremental or absolute measurements Power: 1.5V LR44 Battery (Included) Standard: DIN 863 Digital functions: tolerance indication, on/off . There are 25 uniformly spaced marks around the circumference of the thimble that allow measurements to be read to 1/1000". So after reading, I removed the thimble and used a stainless steel pad and a little adhesive remover (didn't) know where my 3n1 oil was. Question The threads were clean, so not a big deal. If the thimble is clamped up for this, it is quite likely to be distorted and bind up forever. As far as I know, it is not practical. In this case, the screw is part of the speeder assembly, but micrometers without the speeder and use a headed screw, most often slotted. Answer Is the frame bent? How to disassemble cheap Alltrade micrometer. Next, used a gage block and a surface plate (could use a 123 block and your table saw top) and got a reading. Description This auction is for a vintage Micrometer made by Moore and Wright in Sheffield. Bring the spindle back to the anvil using the thimble.

I just my Starret 436-1" from a pawn shop's dollar box. A 3mm (1/8") punch was a good fit here, and I made a fixture to hold the thimble by boring a hole about the same size as its outside through a piece of soft wood and sawing it in half through the hole diameter. sebastian in legacies real name. Your slots look ok in the pictures, but whether the stem is straight, so that the faces are parallel, only you can tell with the unit in hand. Use the force control device (friction collar or ratchet) if present. The lock can be opened up using a small blade screwdriver to carefully spread the gap. 964, centre: Mitutoyo 103-137, right: Daniu 8 micrometer. 21.00 8 ACUTE ANGLE ACCESSORY AAA 64.00 9 FINE ADJUSTMENT KNOB BPRO/24 4.00 9 FINE ADJUSTMENT KNOB BPRO/24-S 4.00 . I usually work using a shop apron on. It probably won't line up right, but get it close. Once the parts are clean and rust free, light machine oil, like watch oil, sewing machine oil, or, believe it or not, micrometer oil, should be used to wipe the inside of the thimble and the out side of the spindle cylinder. 0014 . Next, the wear adjuster nut came off. When using a Mitutoyo digital micrometer of range 0-25mm, after measuring something of size 24mm I have accidentally rotated the spindle beyond the upper limit (above 25) and now the spindle is locked in this position. The desired outside diameter is slightly smaller than the serrated section outside diameter. The quality makes all do the job well and if the tool meets the requirements for accuracy, precision, and repeatability, that is what matters. I supported the frame in small vise with some paper to soften the grip (the vise was snug, not tight) so that the spindle was straight up and down. Removing the lock screw makes it easier to free up. Any gap or unevenness in the meet is a negative. Moore and Wright MEB-MW201-04DAB Digital External Micrometer 100mm (4 inch) 201 Series. Swapping parts is sometimes possible, but there have been a number of variants over the years, and there are parts that are incompatible,. That type is adjusted by removing the screw that holds the thimble to the taper, knocking the taper loose (Gently! There should be two pieces visible: the one threaded into the frame, and a second one still under the thimble. Founded in 1906 by innovative young engineer Frank Moore, Moore and Wright has been designing, manufacturing and supplying precision measuring equipment to global industry for over 100 years. That is done. Using the wrong wrench will lead to heartbreak. These techniques and skills need to be taught to the new generation.When they shut down shop class, was the worse thing schools could have done. No rush. The parts often rely on the spindle for support and may be distorted into uselessness if operated without the support of the spindle. I check this using an optical flat. After insuring the measuring faces are clean, the spindle was run in to just contact the anvil. Though the measuring faces can't be brought into contact due to rust, they are not visibly misaligned. Note that manufacturers have used many, many schemes for adjustment over the years, though this is the one that became most common by the second half of the 1900's. The method varies from make to make, but most Starrett, and makes modeled on them, have the thimble fit to a precision tapered section on the spindle end. ), and reseating the thimble at the correct zero location. If it won't move after a week or so with penetrant, then decision time comes in: let it be, or up the ante a little. I don't think Starret makes/has made interchangable anvil thread mic's like Mitutoyo (and the generic import suppliers). If it won't move after a few tries, more time and penetrating oil are needed, so give it a day or two. Check the alignment and look for anything that might cause binding and retry. THESE ARE SMALL SCREWS. Now the tool can be tried out. . Magnetic base maw std adjustment R 719.00 Incl.

Made in Switzerland. Then comes the neanderthal action: A light, sharp tap on the cap with a soft, light mallet, such as a plastic or wooden mallet. If it requires enough force that the screw might strip or the head break off, then it gets interesting. We started exhibiting at model engineering exhibitions in 1994 and realised from the shows that people wanted quite specialised tooling for their machines and also a wide range of tooling which they . . The same tool in better condition, but cosmetically poor, commonly goes for less than US$10. (25 mm) can easily be used in one hand as shown below. Calibration is where we establish a relation between the reading of the tool and an actual measurement. Nope.

The screw threads were cut on an Aureole thread milling machine and finished with a lathe tool. The questions are: Does it zero? At this point, remove the cap, since there aren't enough threads engaged to rap safely again. "Mitutoyo digital can either be electronic digital with an LCD display (digimatic/ABSOLUTE digimatic), or mechanical digital, with mechanical dial counters (193 series, for example https://ecatalog.mitutoyo.com/Digital-Outside-Mic ).If you mean the mechanical type, these are fairly easy to deal with once you know the construction, and they are fairly rugged, so moderate force can be used. On this model, it slides straight out of away from the frame. Visually, this micrometer has a few issues, good and bad. In my experience the sleeves on Moore&Wright micrometers are all just a bloody good fit on the body, but only held by friction. No abrasive, just lint free wipes and brown paper. It measures 93mm when closed. Note that on many of these mic's, ham-handed users have damaged the screw slots or bent the anvil stem. There are other possible reasons for tightness (mechanical damage such as a bent spindle, raised dings, wrong spindle in the body, for example) but I can't address these issues without seeing the unit, and Starrett is easier and less expensive than I am, and they have a full stock of spare parts. The current (2016) closest equivalent tool from Starrett lists for about US$140 (the 436.1XFL) new. Moore & Wright (Sheffield) Ltd. Moore & Wright 1966MB150 Ext Micrometer 125-150mm . Features Moore & Wright Micrometer Interchangeable Anvils 0-100mm. In my experience the sleeves on Moore&Wright micrometers are all just a bloody good fit on the body, but only held by friction. I have a Brown and Sharpe No 10 older version and it does not appear that the thimble comes apart. This will need to be lapped later, and the spindle face needs it as well. Most makes do something analogous. The lock was adjusted and its parts reassembled. moore and wright micrometer adjustment. AKA 'a light press fit' (when they're new). This is pretty much consistent with the faces being a little out of parallel, and the thread being a little worn at one end of the range. I was not exposed to dismantling precision tools until my apprenticeship at B&S mfg. Starrett has used several mount methods. The speeder sticks out and they are relatively vulnerable. The joint is next to the hole for the wrench, which is also a size that is difficult to find. This will allow for easy reassembly, easy adjustment, and help keep crud and moisture out so it can be adjusted again in fifty years. If it is stuck, Don't Panic! A reasonably inexpensive caliper may indicate to a precision of 0.01mm (0.0005") and have a claimed accuracy of 0.03mm (0.0015"). This combination has the advantage that the alignment of the edge of the thimble with the barrel graduations can be adjusted, allowing the user to set it to fully expose the graduations or split them, at her preference, by running the thimble further up or down the spindle thread. Once the barrel was free enough to use the wrench, I rotated it so the index line (the longitudinal line the 25/1000 marks extend from) was where I want it. When looking at this style, pay close attention to the slots in the screw and stem. 0-25mm Brand new never used. I spent eight months in the tool repair calibration department at B&S. This does not put the zero of the thimble over the index. To oversimplify, and without propagating all of the uncertainties involved, the error was less than 3/10000" for all test points, and the cumulative error was about 2/10000. Rust removal chemicals (derusters, rust converters, naval jelly, acids, lye, etc) and electrolysis should NOT be used.They are much more likely to change the dimensions by removing excess material or growing a surface than a simple penetrating oil. Some of the "magic" penetrating solutions have corrosive properties and can damage precision surfaces. The procedure is the same for larger mics, but a gauge block or rod standard is needed. Be careful not to drop the jam screw. Do not force it. Is it possible to remove the threaded sleeve that lives under the barrel? Key selling points were that the sleeve could be replaced when worn, and that there was a second nut and a spring to allow for take-up of play. No oil goes anywhere else. (I have three 436-2's with no interchangable parts-- different spindles, thimbles, and frames, including two different tapers for the thimble mount-- except the ratchet and the lock). The end cap has a small hole in it for the pin on the micrometer wrench to grab. We don't adjust anything. The Brown and Sharpe manual specifies this be done by grasping the spindle, not the thimble. PAGE 1 961 AND 965 SERIES EXTERNAL MICROMETERS PAGE 2 966 SERIES EXTERNAL MICROMETERS PAGE 3 961 AND 965 SERIES . If the roller is missing, you can make one (not a beginner task), or just replace the assembly. With a micrometer, the base point is the zero. The adjustment should turn holding the knurled portion in one hand and the wrench in the other hand. They have a smaller inherent uncertainty than calipers, in part because they satisfy Abbe's Principle, properly used have greater immunity to the influence of operator technique, and generally have an order of magnitude greater precision and accuracy. Running it in provides the shortest path for getting at least some of the rust out, without dragging it through the threads that give the tool its precision. Just time. Slocomb was a manufacturer of micrometers for nearly a century, and they are common in the used market in a variety of styles. 22K views 5 years ago Here's a quick video showing how to adjust your micrometers so they read zero when fully closed. Left: Moore & Wright No. DuBois argued that a "color line" stretched across what? Watch through the lower end of the bore since will probably hang up entering the lock. . Due to the rust freeze, the thimble was removed first. Initially the M&W micrometers were made to the Aureole designs. The stem moves 0.025" per revolution, as does the spindle. You can get a good fit in the hole and provided it's not. But the drawback: the joint in exposed and gums up with rust, oil, and hand goo. I use a toothpick with the end carved as a thick slot-type screwdriver to grab them and replace them. on Step 9. This may release some tension and allow some motion, then the unit will need to be calibrated. Moore & Wright Micrometer w/Case No. Dial micrometer. If it is not right on zero, loosen the cap, readjust, back the spindle out, and snug the cap again. In the absence of a wrench, a properly sized steel pin can be inserted in the hole, and a piece of wood with a properly sized hole can be cut in half to hold the pin.
