Starrett 711LCSZ Last Word Indicator

so in this video we're going to take a look at the start 7-eleven model indicator now this particular kit that is shown here is the 7 1 1 LC s Z this is one of their more complete kits it has a lot of different options in there along with the kit there were on the outside of the box just a little inspection certificate on who inspected it another small piece of paper talking about keeping it clean and making sure you protect the lever and it's in several languages and then inside the box was a notice concerning that there may be some empty spots in the phone because this is used for multiple different tools so just so you don't think that there's something missing right away I did see in a lot of the reviews of this tool that people were complaining that they didn't believe that they received everything that they were supposed to receive in the kit so we're going to open this up and look at each of the individual pieces and parts and what start calls them and also their individual part numbers if they have individual part numbers in case you don't want to get the full kit you can purchase just the dial indicator and then the 1 or 2 attachments you need or perhaps you just want to get the attachments for a dial indicator you already have this is also known as the last word dial indicator from sorry so I'm going to start at the front and we'll work our way back through these accessories this first accessory is is pretty simple and self-explanatory when you open up the kit as far as what it is and how its name relates this is the double-jointed attachment stated that it's a double-jointed attachment obviously because it has two joints on it this is part number if you want order it separately PT 1 3 3 0 1 3/8 inch diameter on one end and quarter inch diameter on the other end this I see it being used in the mill to help trim up the head of the mill as well as the table and both axes so definitely a nice holder to put this in a Chuck and to be able to quickly start getting the accuracy increased on your mill so this next part we're going to take a look at is a little bit more confusing because there are actually three different parts here so you have to separate them out so these are the three pieces separated out this comes you can buy these individually most of these or as smaller sub kits these two together the the flat bar and this single jointed arm are referred to as their Universal shank and it's part number PT 0 7 1 0 3a and it includes this piece which is part number PT 0 7 1 0 4 F that's referred to as the long and short arm and then in this particular kit there is also this item which is a coupler part number PT 0 5 1 1 6 these are all 3/16 inch diameter and they're just slip fits you can probably if you'll be able to see the slots on the coupler and then there's a slot in a friction fit here as well first use that I see for this and one of the reasons I wanted this item is for indicating on the lathe this this bar is a half inch tall by a quarter inch thick so this can easily go in a tool holder even the standard quarter inch or 3/8 inch tool holders on the sure line and be able to indicate run out of the chalk or centering of a piece to a high level of precision one less tool that you're going to have to make and something that's will be quick and easy for you to do different setups on okay the next item that's included in this set is a height gage attachment this is part number pc2 for 7:06 it's designed to fit into a start height gauge and attach the indicator to that so you can get a more precision rate than what your your height gauge may resolve to since most Heights gauges are going to be probably point zero zero one inches and it's going to be hard on some surfaces to get that read because of the type of the Chuck or the tip I should say on the height gauge so this is nice because here you can get to that half a thousandth and really start to get some some surface details and other items out of a height gauge this does also fit I have a grizzly height gauge and this does fit in it as well the indicator bar is the same size to fit in its Chuck at first you may not understand how this attaches there's a threaded end here and to the holder there's no threads here so so we can't put it in through that hole but there is on the top of the holder a slotted screw that is actually just a plug and we'll take that out at the end of the video and show how these attach but you remove that and then these other items will thread right into that hole so we're going to take a look at these last two together these two that will start with this this larger piece here in the back this is their universal friction holder with shank part number seven one one ei it has a three sixteenths inch shank so we can combine it with some of these other pieces back here with the three sixteenths inch shank clamp that again into a chuck or into a collet if you have a three sixteenths call it to to get some indicators and to attach directly to the the end of the last word dial indicator additionally in this kit is another shaft this is the they refer to it as their surface gauge attachment it's part number PT zero five one one nine and you can swap these shafts out this is just a smaller diameter so this is the larger shaft the 3/16 inch shaft and I'm reading it as 0.1 eight six five and the other shaft I'm reading as 0.1 four inches in diameter on this the smaller section of it and the slightly larger stepped-up section of it is 0.15 7/5 also with the indicator are a few replacement tips these are just simply smaller diameter balls on the ends of the tips so if you're trying to to get an idea maybe use this to determine the smoothness of a surface and what the height of any tool marks are on the surface some of these tips are much smaller diameter and will drop into those grooves rather than writing over the top of them several other uses I'm sure that people would come up with these if you're dealing with a very small hole you'll need the smaller tip things along those lines this brings us to the last part which is the indicator itself this is actually two different items as well so these come shipped together and but if you if you want to keep them separate there is actually a spot in the case for this to be stored separately this is the body clamp it's part number PT 0 7 1 0 1 F this is a friction fit onto the body it is quite a tight friction fit and then on the side is a hole for attaching to some of these rods or other jigs and fixtures that you may make this does rotate as well in case you need it to it is quite the tight fit because it isn't really designed to you don't want it to move while you're indicating but it it will actually rotate you can see the splits in the side of the collar for that and then the indicator itself so this is the start at last word this is a swing arm style indicator so it indicates off of a sideways pressure rather than a downward pressure isn't going to indicate with it this gives a little bit more accuracy just because of the leverage of the arm and the difference of the movement there in this case this indicator is accurate to plus or minus half of one thousandth of an inch and each tick on there does represent a half of a thousandth with the major ticks being 1,000 the range of this is point zero three so 30 thousandths it's not a very wide range on the indicator but for the precision you don't really need that wide range if you're not really meant for rough setups or or depth of cut measuring or things along those lines on the side of the indicator is a small switch you can rotate this back and forth to determine whether it measures in an upward direction you move it in the opposite table measure in a downward direction as the the indicators oriented now so I remove the threaded plug from the end of the indicator just so that you can see that detail it does expose some of the internals of the indicator so you would probably want to keep that in there or just as a matter of course keep one of the attachments threaded in there there are some small flats on here and you can separate the ball attachment and just leave the cup on there if you wish so fairly simple there a lot of varying ways to set this up I think it's one of the biggest advantages of this kit one thing I did notice is that there are no dovetails anywhere on the body of the unit which you will see on almost other indicators of this size but I think with all the other attachments you have here you really don't need that dovetail feature or function you could probably also make a dovetail or they may even sell one already made to give you that capability as far as the quality of this indicator and the cost of this indicator this is on the high end there are more expensive indicators out there certainly but there are much much lower cost indicators out there if you're just getting started in machining you you probably don't want to go out and invest the amount of money that this indicator costs however it will last you a lifetime if taken care of properly and you really wouldn't need to buy any other indicator of this style in the future again this indicator is north of 200 dollars in this set in this kit I believe it's maybe 150 or so might be a little bit lower than that without all the pieces and parts and accessories some of these accessories though they sell for twenty to twenty-five dollars each so if you if you want the accessories definitely get the kit and for some savings there the main reason I purchased this particular indicator was for the accessories and because I wanted very high quality indicator this is definitely the best indicator that I've ever purchased normally I purchase off brand names and lower-cost indicators because I wasn't doing any high precision machining but if you are going to be getting into those high precision machining tasks or if you're going to be building something to spec where you have to guarantee that it's within a certain size range and those size ranges are down into the thousandths of an inch then you'll probably want a good quality indicator that's going to be very very reliable such as this if you're building parts that are into ten thousandths of an inch then most most indicators are going to work fine for you and you don't get need this level of expense or precision if you are going to be building parts for your own hobby uses such as let's say radio control engine crankshafts those can spin in the tens of thousands of RPM range or if you're building radio control jet engines or other types of high reving items then the cost of this really becomes justified
