Hi Tom, your measuring device sounds very similar to one of my jigs but even simpler to build. Every once in a while we have an inspiration, and get lucky and build a tool or jig which actually works well for us. May be next time I need a measuring jig I'll build it your way.
Thanks for sharing your idea: Paul Franklin ----- Original Message ----- From: Tom Huhn To: [email protected] Sent: Friday, January 12, 2007 8:06 PM Subject: Re: [BlindHandyMan] Two measuring gages or jigs About ten years ago I made something like these measuring devices out of wood. I cut two pieces of alder 3/4 x 1 about 5' and 3' and I cut a dove tail slot down the hole lenght and cut a matching piece to the dove tail slot that slides in the slot. I put a 't' nut in the 3/4 x 1 with a thumb screw to lock the slide stick. I use these all the time for taking measurements for cuts and they work extremely well and very acusrate ----- Original Message ----- From: Paul Franklin To: [email protected] Sent: Thursday, January 11, 2007 11:53 AM Subject: [BlindHandyMan] Two measuring gages or jigs The recent interest in measuring devices on this list prompts me to describe a couple of types of measuring gages or jigs that I built about 25 years ago, and that I still use to day. The first was made with a 4 foot length of 3/16 stainless steel rod and 2 pieces of ¾ square steel bar stock about 1 and ¼ long. The idea is to permanently affix one of the pieces of bar stock perpendicular to one end of the rod, either by gas welding or by threading the end of the rod and drilling and tapping the bar stock. The other piece of bar stock is drilled perpendicular to it's long axes, so it can slide smoothly along the rod. A second hole is drilled in this piece of bar stock parallel to it's long axes, which intersects the first whole. This second whole is tapped to accommodate a threaded bolt that acts as a set screw to lock the sliding square stock at any point along the rod. I used a bolt with a large knurled head that could be easily tightened or loosened by hand for the locking bolt. To use this device, I align the end of the rod with the fixed block at one end of the measurement to be taken, and slide and tighten the movable block at the other end of the piece or gap to be measured. I then can transfer this measurement to a board for cutting or use it to set stop blocks on a chop saw or set a fence on a table saw. I have found this device to be quick to use and accurate enough for cabinet work. Over the years I have built several shorter versions of this device for use in tight areas. My second home made device has turned out to be especially handy for installing base boards, door trim, interior studs or wall paneling. It is primarily made out of wood and it telescopes from 4 to 8 feet in length, and can be locked at any point between. It is made from a 4 Foot, clear ¾ pine board about 2 Inches wide. I cut a 3/8 Inch deep by ¾ Inch wide groove down the center of one of the 2 Inch faces of the board and ripped a 4 Foot strip of pine to slide smoothly in the groove. I next cut a 4 Foot long by 2 Inch piece of ¼ plywood and glued and nailed it over the groove in the pine board, to make a 4 Foot box or sleeve for the pine strip to slide in. I then cut a 2 by 2 Inch ¾ Inch thick pine block and drilled a ¼ whole in its center. Next I temporarily aligned this block on the plywood side covering the groove at one end of the device and with the sliding strip removed, I extended the ¼ Inched Whole through the plywood, into the groove, but not into the pine board at the bottom of the groove. Next I tightly mortised a ¼ square nut into the face of the 2 by 2 Inch block so it lines up with a threaded bolt inserted through the whole in the block and is flush with one face of the block. With a ¼ bolt threaded through the block and nut, and protruding about ½ inch below the nut I inserted the end of the locking bolt through the plywood side and into the groove below. I then glued and nailed the block and locking bolt assembly to the plywood side covering the groove. With the sliding pine strip inserted into the groove the threaded bolt on the block can be tightened to lock the strip in any position between 4 and 8 Feet. To use the device I align one of its ends with a wall or the floor and slide out the strip to make the needed measurement. With the locking bolt tightened this measurement can then be transferred to a board or panel for accurate cutting. I don't use this jig often, but it's nice to know that it is hanging on the shop wall when the need arises. I think that it has taken me longer to describe this stuff than it took to build it. Sorry for being so long winded.

I thought that I was the only one who used his chin or cheek to hold down the saw to align the stock. I don't know how many times my wife made a comment when she saw me doing that. Now I can tell her that it is the proper way to set up the saw. Great description of the tool and use.

The threaded rod is six and a half inches long. The large rectangular nut is the one you most commonly use for measuring. The other nut is used when/if you want to lock the rectangular nut into place to hold a measure or even to use it as a sort of monster feeler gauge. You should notice a small notch cut into one of the longer sides of the rectangular nut, this is to help orient it. You are correct, the half inch marks are where a thread is continued all around the face of the milled side of the threaded rod. Each revolution of the nut represents one sixteenth of an inch so, half a turn is a 32nd of an inch and a quarter turn is a 64th. two complete turns is an eighth of an inch and so on. If you require more than 6 inches then you thread the 6 inch rod bringing your measure up as far as 12 and a half inches, add the 12 inch rod or the 18 inch rod or any combination there of and you have the lengths you require. What I really like about the measure is that I can set a size off of a plan or I can take a measure from a project, lock the nut into place then go to my miter saw and pressing the end of the rod against the blade, adjust the wood to be cut until it is flush with the nut and cut an exact size. I frequently end up with a bit of a bruise on my chin from holding the saw down against the board, I do have a bungee cord hanging on the cabinet I can use to hold the saw down to the wood while I set the distance precisely but this takes time and I often don't bother. I can as easily use it to very accurately set the distance from rip fence to blade on my table saw and so on. This is of course not adequate beyond 42 and a half inches although I suppose you could get more rod if you need or want it. I do try to keep a stick or two around here precisely 4 feet long but rarely do I need it. Even when I raised this addition it was mostly fine to use the dimensional lumber and/or relative measures with a locking tape measure. I used a block to space studs, locking tape measure to determine the actual length of span for building the roof trusses, I didn't actually even have the roto ruler back then but a folding meter stick ruler. A tactile ruler though just isn't accurate enough for cabinet work and hardly for structural framing. Things like carpenter squares known to be 24 on the two inch leg and 16 on the inch and a half leg can also be helpful in frame construction.
