The safety clamp shall be used for an entire string if the Casing/Tubing/Drill pipe is flush, meaning no upset or coupling. One of the most important point of safety is never mentioned. An that is cognitive load. Unfortunately for humans when cognitive load meets our full cognitive capacity we don’t fail gracefully.

Part 2 is now finally taking shape, be proud of yourself! No, this isn't complicated...but it always puts a lump in my throat to complete something and being able to say, "I did that!" Now it's time to complete this instructable and call it yours. Beyond that, we're going to fit a nut into the bottom end of the toggle clamp by carefully grinding out a channel for our nut to fit into. We'll fit it to the underside without fear of it being jarred loose as upward pressure will keep it in place. Besides just the upward pressure, we'll use some sort of metal epoxy mixture to glue it into place. Now, I've made a couple of these (one with the metal epoxy and one welded), and have to admit I'm more partial to the spot welded nut, but the epoxied nut hasn't failed me yet. Oh, but what do we slide the jig 'in to', you might ask. Well, I've got a few example pictures listed above as well as a link to show you what your jig will need to have to add this clamp. Now, it's fair to mention that the ones I bought fit very neatly on a 3/8" carriage bolt (it's 1" in diameter). If you plan on using a 5/16" or 1/4" carriage bolt to match the nut you implanted into the toggle clamp, you might have to do a little more searching for a rubber solution. You might try a rubber tool dip if you aren't able to find a small enough rubber furniture tip, or even scrap the carriage bolt completely and go with a threaded rod of the same size with a pre-drilled hole in a rubber stopper.Whichever size you choose, it will still need to be modified. Modification will allow the toggle bolt anchor to not only fit through a drill press table slot if it's slightly too big, it will also allow it to actually clamp down and bite into the bolt, keeping the bolt from spinning as you turn the knob on the top. No, no, this isn't a shameless plug for another of my videos, this is a technique that has saved my hiney in more ways than I can count. I suggest buying a 3/8", 5/16" and 1/4" size toggle bolt. They're relatively cheap and are good to have around the shop anyway. An ideal drill guide for all the rotary tools in the market today. The easy to use guide has a lever to adjust height and is heavily preferred in the manufacturing industry. To modify the toggle bolt, all you'll need to do is remove the shoulders of the anchor. I've included images in this step to show what I mean by 'shoulders' as well as before and after images. Once you've taken a file or a grinder and removed the 'shoulders', it will make the profile of the anchor more flat, which is also good because it'll catch better on the bottom of your drill press.

Once the shoulders are removed, we'll do something that will keep the toggle anchor from skidding off the ridges of your drill press table: we'll make notches exactly where the ridges are. Now, we could measure these things out...but I like working with patterns and allowing objects I'm working with to print themselves, giving me a more exact, less mistakable procedure. So what do I do?As the name states, it is a “safety” device. It’s an extra effort to prevent a single joint or a complete string of pipe from dropping down the hole. This jig really is a two parter, depending on what you're planning on doing. If you already have some sort of jig you've rigged up for your drill press, Part 1 is all you need. You will, of course, need to create a channel in your jig so that you can slide your jig below the Part 1 clamp.

Small drill guide that is ideal for medium sized workshops. The stand weighs 2.5 ounces and is comparatively quite light, the guide can be used for precise holes and is perfect for wood crafters. Do not use a safety clamp in combination with automated slips. This does not create a safety factor but becomes a hazard. When using automated slips, and you install a manual safety clamp, you will risk major equipment damage should you encounter an impact. Even though Company Rep’s might insist in using the clamp in this configuration, it is strongly recommended not to do this. Okay, if that's not understood, please leave me a comment and I'll try to dive deeper into this subject for you, although I'd probably have to create a video to show what I'm talking about... The tool is perfectly suited to Dremel rotary tool models 400, 398, 395, 300, 285, and 275. Since Dremel is such a popular brand, consumers will want specific accessories that work perfectly with their Dremel power tools.So we've put our 1" Forstner bit in our drill press. Now let's take the 2" x 9" x 3/4" piece of hardwood and we'll drill two holes in it. The first will be the 1" hole (we all want to start large and go small with Forstner bits), followed by the 3/8" hole. The 1" needs a depth of a 1/2" while the 3/8" will drill the rest of the way through. I have made a few drawings in sketchup that will give you the exact dimensions. Also consult the video as it will give you all the information you need. The other extremely common one is what I call in “insurance” model of risk assessment. In insurance the loss of life has a very low value because dead people don’t sue. In reality average people have a much higher regard for life. But why does flat matter? Flat matters as clamps require two surfaces for clamping, both of which should, in theory, be parallel to each other. Using claps on my drill press was a balancing act...one that I never seemed to win.

Let's start this instructable off with a question: How do you clamp materials to the drill press? Or don't you? Look buddy, I'm not judging, trust me, I'm not. I've got my own safety demons that stare at me while I'm welding in shorts and flip flops. One of these days, we'll learn though, right? Again, as I have highlighted in the blog on slips, avoid mixing parts from one manufacturer with the other, even though they might seem compatible. Warranty on the tool is gone, and as tolerances on the parts might slightly differ, you could end up in a world of hurt. Once we've found a rubber solution to the business end of our bolt/threaded rod, we'll head on over to the next step.Crafts man is reliable name when it comes to hardware and this drill guide just enhances their reputation in the market. The guide can be installed either on flat surfaces or on inclined ones. The body is made from stainless steel that is both lightweight and durable. Do not ever use a safety clamp as a hoisting device. This device was not build for lifting and is not rated as such. The handles on the clamp are for manual handling, not to be used as pad eyes.
