BEFORE you read this I'ble on how to make the drill press shown above, I want to UPDATE that:
I ended up retiring the drill press I made in this instructable, and now, 2 years later, I bought a mini compact variable speed drill press on eBay. If you might be interested in a drill press like this one, I highly recommend you watch my detailed review video on it, highlighting its most valuable pros & cons - which there are many!
You can click here to watch the video, or watch the embedded version in the last step of this Instructable, including explanations on why I chose to purchase a drill press after building this one.
I've come to the point where can't build more advanced woodworking projects, due to the lack of a drill press*. I have a list of tons of projects that I want to attempt, yet am unable to complete them due to the lack of a proper drill press - one that can drill at a 90 degree angle.
I am unable to find a used drill press in my area, and with the amount of money that I'm willing to spend on a new one, I would get nothing - they are way too expensive!
I thought of asking for one as a birthday present, but the amount of money that would be needed for buying a drill press that isn't flimsy and would last long just isn't worth it - they are just way too expensive, and I don't even plan on using it so much. Even if a drill press was a tool that I would use every day, I still wouldn't feel comfortable spending a couple hundred dollars on one (way-too-frugal!).
So I need one. I really do need a drill press. I don't want to invest in one, as I think it's not worth it, enough . I try thinking of a plan for building one, but all of my designs require a drill press for building the drill press.
To build a drill press, I need to buy a drill press, but if I already have a drill press, why would I build a drill press? That's the problem with (many, if not most) homemade drill presses. You either need a drill press for making it, or you spend many, many hours working on one, but it turns out inaccurate. I practically gave up. Impossible , or not?
Well, in my case, many months later, all I had to do was well, nothing to get the problem solved. Out of nowhere, all I had to do was draw a quick sketch of the idea that randomly came to my head. This idea will be shown in the video below, and will be explained in the next step.

Technical Specs that can be modified easily to fit your needs:
*(Well, I actually do own a drill press. Unfortunately, it takes FOREVER to align it to a point where it looks like it's close to square, and even then the angle changes as soon as I apply a little too much pressure. It's just too flimsy overall. Perhaps useless is the correct definition ;)
The reason for why I called it "basic" is because I wasn't sure if what I planned out would actually work as planned (this step was typed out before I even started building the drill press). If everything actually would work out as planned, I would add the extra gadgets that I planned on adding in the first place...
I hope you'll forgive me if I use an incorrect term for a part that I don't think exists :)
The special plan was to make a cube out of wood. Or a box - I'm not sure what it should be called, but I wanted to make a 4 sided piece of wood that would slide up and down on the column. Pretty simple idea, right? I planned on making it out of plywood, with the pieces connected together with butt joints (screws). I'm sure better joinery methods do exist, but this is the only type of joint that I know I can make with a circular saw, and without too many difficulties. It's also easy to tighten, and easy to disassemble in case something needs to be modified. Any accidental inaccuracies would be corrected with the spacers, anyway.
The pieces of wood that are between the cube and the drill are spacers which increase the space between the chuck and the column, allowing for me to drill in the middle of a big board, using a big holesaw, or anything else like that.
If I don't saw the parts of the cube perfectly, which will probably happen, or don't attach the drill to the spacers perfectly, which will probably also happen, I will need to re-adjust the parts so the drill press will be able to drill perfect 90 degree holes. To do that, all I have to do is loosen the bolt that connects the column to the table, and stick a spacer between them. I don't think my cuts will be off by a lot, so to know where to add them, I'll use this GENIUS tip by Wood Magazine . This video explains it pretty well too.
Not very special, yet might be the best tip you've heard all day: My original thought was to drill a hole in my plywood table which stays outside, and connect the column straight to it, so my table acts as the drill press table. I would only take only the drill outside when I needed to use the drill press. The problem with that is that the column will rust from the humidity. I thought I'd take also the column inside too, but then it would be hard to store in vertically, since there wouldn't be a base. I would also have to adjust the squareness of the drill press before every use. That was enough for me to understand that I should drop the idea... Perhaps you could do that in your workshop?
Want to make this project? Here's a list of what you'll need. You should be able to find the parts in a hardware store, on eBay, or maybe outside, on the sidewalk that's near your house! If you don't see something that you think should be here, or would like to know more about a specific tool/part that I used, feel free to ask in the comments.
I made it for FREE since I already everything that was needed on hand.
Subjects: Woodworking, Metalworking, Making Your Own Tools.
I decided to start with the easiest part of the build: connecting the column to the base.
I measured to make sure I was in the middle of the particle-board board, and then drilled a 10mm hole, while doing my best to keep it at 90 degrees with my homemade 90-degree drill guide . I put an aluminum washer on the bolt before tightening it.
Both of the internal sides of the cube have to be 60mm, since that's the diameter of the column.
They will be 80mm tall since that's the biggest part of my drill that I can attach stuff to . That means that I will be cutting a rectangle that's 60X80mm. I clamped the plywood tightly onto the table, marked the dimensions, and used a speed square to guide the cut. The two others will be 80X80mm, because of 60+8+8: the column + both pieces of plywood. Having them oversized is better, just to be safe...
Even though I had practiced a lot (my first time using a big circular saw), the cuts didn't turn out as well as I had hoped. With a table saw, they could have turned out perfect, but I obviously don't have one. To be honest, the cut quality doesn't even matter that much. Why?
Marking the pieces oversized, and cutting them out undersized and out of square was actually better than cutting them to the 100% correct size. Hooray!
Sorry for the lack of pictures, my attention had to be on the f̶i̶n̶g̶e̶r̶ ̶e̶a̶t̶i̶n̶g̶ ̶t̶h̶i̶n̶g̶ circular saw 100% of the time...
I aligned the pieces together in the shape of a cube on the column, and clamped them together using the help of another person, as I needed another pair of hands.
The last thing I wanted to have is the wood splitting, so I made a WORST WORST WORST case scenario, testing both the plywood, the screw, and the pilot hole. See a picture of this here , where nothing went wrong (to my surprise). I drilled a pilot hole in both butt jointed pieces and screwed in the screw halfway. After all of the screws were tightened halfway in, I enlarged the pilot hole of the (first) outside piece, tightened on a teeny tiny clamp, and screwed in the screws with a screwdriver. Be gentle and don't force them in!
If the wood ever does split (I hope not!), I'll find a way to reinforce it... It should be too difficult. I recommend using thicker plywood.
See step #1 for why these are needed.
I decided to use some pretty thick maple wood that I had salvaged from the same chair that I salvaged the plywood from. I cut two pieces of it to 80mm long, since it was already the correct width that was needed. I would have normally used the super sharp handsaw that I won in the Instructables Shelving Contest, but I didn't, because I wasn't sure if I had removed all of the staples, which could ruin the whole saw. I used the circular saw instead, since if there were any left, they probably wouldn't have done any damage to the carbide tipped teeth of the blade.
I then glued both pieces together with wood glue, added a few drops of CA glue, and clamped them together. I came back the next day to glue the spacers onto the cube. I wish CA glue would cure just a bit slower so I would have just a bit more time to move it around!
The bolt that tightens the column onto the table sticks out a little over a centimeter below the table. I needed to add some legs to make sure it was the drill press was stable, and could be clamped to my workbench.
I cut four pieces of beech wood to a length of 4.5cm. After that, I drilled pilot holes, and drove in 1 screw for each piece of wood, in each corner. To make sure the screw sat under the surface, I used an 8mm drill bit to counterbore (I believe that's not a countersink) a hole.
Now I can also put the clamp between my workbench and drill press table, allowing for easy clamping while drilling. Here's a picture of that.
First, I started by clamping the drill onto the spacers, as shown in the picture. I locked the trigger at "full speed", so I could push the clamp another centimeter up. I cut an inner bike tube in half, wrapped it, tightened it as tightly as I could, and then tied it.
I cut another piece of maple, the same type of wood that I used for the spacers, this time with my handsaw, to the length of 8cm, and then glued it to the back of the cube. What a nice surface finish!
I also cut a thin, yet extremely strong piece of beech plywood to 15 cm long, and drilled a 12mm hole in each end. I then cut a piece of regular beech wood, and repeated the same process. Both of the pieces were so hard that I didn't even think using my Japanese saw to cut them!
I used some really big bolts and hex nuts to tighten both pieces together, clamping everything in between.
The problem? When clamping hard enough for the drill not to move, the cube wouldn't be able to slide up and down, since it was also being clamped. The inner tube was a great rubber band, but it didn't really do anything :(
Didn't work, didn't work, didn't work. Argh!
A nice trick I've learned is when I'm stuck on something for a really long time, to leave it. I stopped and went to do something else, and as I was told that the idea would come out of nowhere, it did! The only issue was that I didn't understand how I didn't think of it earlier! ;)
I cut two pieces of beech wood to 12cm long, used CA glue to glue them together, and drilled a 10mm hole in two sides, right on the line.
In the same length, I cut another piece of beech plywood (the same kind that was used before) and again, drilled a 10mm hole in two sides. I found two bolts and two washers, and then tightened both pieces together, so they sandwiched the drill in the middle, between them. To improve the grip on the drill, I put the back side of a silicone phone case that I had lying around between the wood and the drill, which increases the friction.
I slid the cube off the column, clamped it to my table, smeared a generous amount of glue onto the spacer, and then clamped it all everything together. I wanted to add screws which would connect the drill holder to the spacers with more strength, but didn't because I already tightened the bolts that held the drill, which blocked the way. I didn't feel like doing everything for the second time, but if I ever do need to remove the drill for some reason, I might screw in a few screws, though I don't think they're even needed. I came back an hour later, slid the cube onto the column, and added some more clamps.
Now, while typing up the Instructable, I realize that the drill holder is pretty much like Izzy Swan's $2 clamps .
The drill obviously isn't going to spring back up like a store bought drill press because of a thing called gravity. Ever heard of that annoying thing? I can improve that a bit, pretty easily though.
My intention was to use a bungee cord that I had laying around. It was pretty long, so in its full length, it didn't do much, and when folded in half, if was way too strong. Luckily, the bungee cord wasn't my only option.
I drilled a hole in the top of the big plastic bolt thing that's on the top on the column (this bolt is used for adjusting the height of the leg +/- a few centimeters), and inserted one hook side of a pretty big tension spring into the hole. I then drilled another hole in the piece of the drill holder that was glued to the spacer, screwed in a small hook, and inserted the other side of the spring, making sure that it was being held properly.
Play: Able to wiggle from side to side - not a perfect fit.
I noticed it earlier, yet waited until now. There was some play between both of the side (the smaller ones, tightening the screws doesn't change it) pieces of wood of the cube, since they weren't perfectly parallel. I made a plywood wedge, which fixes that perfectly.
I also made a video on how to make one:
I had to repeat the process because my first one fell, and disappeared somehow, and unlike what I showed in the video, I used CA glue to glue the wedge to the cube.
As I mentioned earlier, I ended up retiring this homemade drill press. I instead opted for this compact drill press that I bought on eBay. As promised, here is the detailed, action-packed review video!:
I ended up retiring the drill press I made in this Instructable for several reasons, some of which were design mistakes on my part. To summarize, the corded drill was always challenging to hard to mount precisely in its "clamp" and was physically uncomfortable to use overall. I had a bunch of ideas for fixing these issues, but unfortunately, this isn't my drill and I wasn't allowed to modify and mount it more permanently...
I do hope to see a lot of use from it in the future - As Theodore Levitt once said, people don't buy the drill press, they buy the holes with the additional benefits of a drill press! Ok, he didn't say that.

This is an excellent instructable in all ways but one. I know everyone does it on instructables but I wish you hadn't called it free. That is misleading and basically dishonest. I guess everything is free if you already own everything needed. In your sense I could make a free diamond ring in a gold band if I already had a $10,000 diamond and a $600 gold band to start with but to call that free is a lie. It would still be a $10600 diamond ring. The honest cost is the cost someone reading your instructable would need to spend acquiring needed parts if they don't already have them. This is a good low cost design but it isn't free.

Please give him a break. The guy is only sharing one idea or one way and if you don’t have certain hardware or parts from his list yeah then technically it wasn’t free but your time isn’t without value either so let’s keep it polite. At least someone can use the basic plans to modify or incorporate their own ideas or parts they have on hand to create their own drill press

Thanks. This type of stuff is always an issue. I write how much parts and materials cost for me. There no end to counting up how much every single tiny little thing costs...
I spent a few months gathering the parts that I needed for the build. If you don't have the parts necessary for building the drill press, it should cost you only $25. Depending if you actually have a drill. Or if you're able to find wood for the base. Or where you live. Or if you own a few tools to make it. Or if you pay for your own electricity bill.........
If you mine with tools that you bought previously a diamond that's worth $10K, then yes, you got it for free. That doesn't mean that everyone can get it for free, but it does mean some can.
Would it be possible to build this with steel and more precision?

Yes, but I didn't have the resources. Oh my... A steel square would be great. But you need to find a way to connect it to the drill properly.
Please for the love of wood, take this 'ible down.
these things are good for nothing, not just this one... all of them.
They don't drill accurate holes, perpendicular straight holes, or even holes the SAME SIZE as the drillbit you are using.
Please trust me when I say "been there, done that, pulled my hair out trying to make it do what I want, then going out and buying a proper drillpress"
These things are an abomination, sent to test the patience of Job (the man).
If you are at the stage where "more advanced" woodworking is your norm, I must assume that equals "more accurate", and every. single. one. of this style of "drillpress with a handheld drill attached" either homemade or store bought are...
they have waaay too much slop in them, from the cheap bearings in the drill that move off axis as you apply pressure, to how the stands are made,and how the mechanism works; every hole you drill will be different.
A drillpress is designed to give you the SAME hole, over and over and over again, awake, half asleep, with your eyes closed; the SAME HOLE, same as the last and the next.
Do yourself a favor, spend the money on a bench sized drillpress, they don't have to be $$$$$, but don't buy the cheapest one either,
