Max, You do not have to remove the threaded pin to align it to the ruler. Just loosen the nut off a little. You will be able to feel that the end of the pin is milled flat on one side, the side which engages the slot running the length of the ruler. You can feel that because it fills one side of the rounded hole along the slot at the back of the casting when properly aligned. All you need to do is rotate the pin until it fills the half of the hole on the same side as the slot in the ruler will engage and the ruler will slide right in there. Then just screw the nut up tight and you're in!

A combination square, which my dad called a try square, is very useful around the shop especially for a blind worker. It is as every bit as effective for transferring distances as a click ruler or a rotomatic. The one I have had for many years was a little off square so I went to buy a new one. I found that they come in ruler lengths of 6, 12, and 18 inches. I left the store with all three. It has two parts, a thin metal ruler, and a casting which has two machined surfaces, one at 90 degrees and the other at 45 degrees to the ruler. The casting part also contains a bubble level and a sharply pointed scribe is also stored in a hole. Neither of these is likely to be very useful to a totally blind person but they are there anyway. Although the lines were apparently etched into the surface of the ruler, it would take some pretty sensitive fingers to read it by feel. You could always get the exact measurement from one of the afore mentioned rulers and use the square to transfer the distance to the work. OK, now that you are convinced that you need a combination square you can get out the one that you have had for years and start using it. When you loosen a knurled nut that is in a cutout in the casting the ruler can be slid back and forth. It can also be pulled or fall completely out. That is what this message is about, how to put it back in. It's a piece of cake for a sighted person but only a little more difficult for a blind one. The first step is to remove the knurled nut. When you turn it the screw just turns inside the casting and it never unscrews. 1. Stick the ruler into the slot it came out of and up against the screw. You don't need to use a lot of force, just enough to keep the screw from turning. Do the next step over a clean workbench or table. 2. loosen and remove the nut. There is a spring under it so be sure to capture it so you don't lose it. Place the spring and nut in a shallow dish to keep them from rolling away. 3. Remove the ruler from the slot and hold your hand under the casting while turning it so the slot is down. The screw will slide out into your hand, or fall on the floor if Murphy has anything to say about it. 4. Examine the screw. You will see how it holds the ruler in place. 5. Place the foot of the screw in the slot in the ruler so the screw is at right angles to the ruler. 6. Holding the screw and ruler, slide the ruler into the slot on the side of the casting so the screw goes into the hole where the slot gets wider. 7. Push the ruler all the way into the slot and the threaded end of the screw should protrude from the place it came from. 8. Place the spring over the end of the screw and then thread the knurled nut onto it. Snug it down so the ruler won't fall out again. That's all there is to it handy boys and handy girls. I've already posted the instructions for using one of these squares to set a miter gauge to exactly 90 degrees. I also use it to set the distance between the saw blade and rip fence, and to set the position of a piece of wood for cross cutting with the miter gauge. The uses are limited only by your imagination. Regards. Max. K 4 O D S.
