In this step (and the next) we'll be able to knock off these items from the overall materials list: We'll use a 1/2" Forstner bit and place it where we put our compass point, and we'll do both arms the same way. While we're at it we'll skip a little farther in the video instructions and go ahead and drill the holes for our aluminum tube to go into. Again, it's crucial that it rocks against the plywood when this is complete.įinding the center and using the trusty compass. You can either rough cut it on the bandsaw and clean it up with a belt sander, or just sand it. It is crucial that you get it as round as possible as we'll depend on that curve being able to hold pressure from the drill press as it supports the drill plate. Again, this needs to happen on both pieces. We'll put our marking point at the very end of the 14 3/4" side and the metal point on the line we drew in the center, and we'll draw our curves. From here we want to make the one end of both pieces rounded, so we'll get a compass and set our radius at half of the 1 5/8" distance which equals 13/16". Let's take the two 1 5/8" x 14 3/4" x 11/16" pieces of hardwood (I recommend strongly hard maple as you'll be cutting part of it out and will need that extra strength) and draw lines down the dead center of both, on the 1 5/8" face. If you choose to not use aluminum tubing, please leave me a comment below and let me know how it turned out for you.

I have never tried using this without the tubing but think it would be problematic. We'll also be using aluminum tubing as both a spacer and as a method of keeping the arms tight against the back. This will require a chisel for one side and a bandsaw or some sort of handsaw for the other side. I've included a fail picture to show that mistake as well as a picture for the fix.īefore we get started let me also add that in order to fold both of these arms down past the other (so that our angle drill plate lays flat at zero degrees on our protractor), we'll have to notch out areas in both arms. As the two arms are used to hold the platform (with the sacrificial drill plate), I didn't realize that one of those arms would actually be closer to the platform and need to have that angle (duh, I know). Admittedly, I made a mistake while I was making the video and didn't take into account that one of the arms would actually need to be run through the table saw to create an angle. Rather, they will rotate in a way that will hold the platform in different positions, allowing a precise angle to be used. Both of these arms won't actually become larger. Okay, maybe "Extendable" is not the most correct word here. Let's also make it precise and easy to measure the angle, just for chips and giggles. We need a nice solid defense against the wicked witch of the Press and her evil sister, Forensa the biddy. We need to secure the work piece to the drill press table. So if we're going to drill at an angle with a Forstner bit, we need to be smart about it. This is why cutting a larger diameter hole after drilling a smaller hole is nearly impossible to do, unless you're using a drill press (and even then I'm not a fan of doing it). Without it we are fighting to keep it where we want it to go. Nope, it's major, important duty is to act as an index for the rest of the bit. There's a good reason for that, and it's not for cutting. Flip the Forstner bit onto its side and you'll notice that the pyramid shaped point extends past the blades and the teeth, and protrudes farthest from the cutting side of the bit. From the point to those teeth are a pair of chisel like cutters that slowly skim the wood surface and cut a hole. Look at a Forstner bit and you'll see teeth on the outer rim with a pyramid point in the exact center. It wasn't until I saw a demonstration for a Forstner bit actually doing that forbidden thing did I begin to wonder if it were possible or if the host was using a trick bit. I remember looking down at my project, all chewed up from the spinning garbage disposal looking monster that was slowly powering down, and thinking, "Never again will I attempt an angled hole with a Forstner bit." And it stuck with me for a long time afterwards. I know, I know, not life shattering terrifying.unless you were me. Dear reader, I tried to drill a hole, with a Forstner bit.at an angle. No, I didn't burn down the parents house with grinder sparks and sawdust, I didn't impale myself with a scrap from the table saw, nor did I electrocute myself with an ungrounded prehistoric hand drill (well, no, I did do that). When I first started woodworking XX years ago, I did something so moronically stupid that it kept me grounded with paranoia from ever doing that thing again.
