Screw it! Ultra-Precision for Shopmade Tools
Вставка
- Опубліковано 26 сер 2024
- Need to add a precision adjustment to a shopmade jig? Want to position it, level it, or move it in small, accurate, on-the-nose increments? Use machine screws! Certain sizes of machine screws have a thread pitch (the distance between each thread) that corresponds to a small common measurement. This is true for both Imperial and metric screws, and you can take advantage of this when building jigs and fixtures.

Custom Saw Stand: ua-cam.com/video/GFF57NC4PCY/v-deo.html
In the last video, "Custom Saw Stand," we use a 3/8"-16 carriage bolts to adjust the height of the saw stand -- one turn raises or lowers the stand 1/16". On that particular project we used a metal T-nut as an insert for the bolt, rather than cut wooden threads. The reason is that the threads must withstand a good deal of pressure from the weight of the saw stand and whatever it's supporting.
There is no such pressure on the stops that I show in the short video, which is why I was able to use a tap to cut threads in the wood. Furthermore, the wooden threads offer a great deal more friction than metal threads, and this helps keep the stop where I want it. I could also use a jam nut to do the same thing, but then I'd have to reach for a small wrench every time I made an adjustment. The wooden threads are more efficient.
If you are worried about the durability of wooden threads, two of the stops I show in the video are 20+ years old and still serviceable. Just be sure to use a very hard wood such as maple, oak, or ash. You might also drip a little penetrating finish (such as tung oil or Danish oil) into the threaded hole. This soaks into the cellulose wood fibers and makes them a little harder as it cures. If the threads become loose over time, drip a little Chair-loc into the hole to expand the fibers.
Bees Wax is great for threads in wood too. Also, the larger the diameter of the screw the more durable or will be, and more accurate.
Plus, if you glue a 6” diameter disk of ply or thin steel to the screw, and divide the circumference into 8 (for the 1/32” pitch screw) or 10 (for the 1mm pitch screw), you can now work in very accurate tiny fractions.
@@G58 Good tip. I had a sentence in the original video telling folks they could use the slots in the screw to count half turns and quarter turns, but we had to cut it because it put us over a minute.
@@WorkshopCompanion Cool. Thank you. Will check out your other vids.
Does this guy not look exactly like Pinocchio's father?? I guarantee you he has an animate wooden child hiding somewhere.
@WorkshopCompanion at least we know you cut it with precision
"If you think in meters" is a phrase I hope never disappears.

No much chance. It's interesting to consider that the first colony to rebel against the English monarchy and leave the Empire is one of the last to remain dependent on the length of King Henry I's foot.
@@WorkshopCompanion exactly! I'm a filthy metric-lovin Euro, and it drives _me_ nuts! 😆🤪

I appreciate a youtuber who considers his global audience and offers metric as well. Thank you
Most welcome.
Note, however, that the USA never lost a war until it went metric.
@brucewelty7684 doesn't change the fact that the imperial system and its units are deeply silly. The meter being subdivided into units which are 1/10th the next largest unit makes a whole heck of a lot more sense then the foot being divided into 12 inches, the yard being divided into 3 feet, and the mile being divided into 5280 feet. for my money, at least
I have a philosophy that I feel fits this: if you can't make it precise, make it adjustable
@Tekagi im looking for the bit where the commentor claimed that
Exactly, not the same, but I've been sewing for many years. Needed a new belt but couldn't find one that was as adjustable as I needed for my fluctuating weight. So I got some buckles and made an adjustable belt, one side closed off.
Now my sister comes to me asking to make her and her friends some all the time. Materials barely cost enough for me to charge them more than 5$ and the sewing is pretty simple so it's not even a laborious effort. And I have a belt for the rest of my life until it wears out, and can make a new (and maybe even better) one when it does.
No. It’s precisely adjustable.
Tolerance , some call it tat
@@marktimmer2212 tolerance is not equivalent to being adjustable. Tolerance is the amount of wiggle room your precision has, mostly due to the limitations on how consistently precise you can make things

Does this guy have a TV show? I 100% would watch him
You're already watching it! Lol
Even better, he has a UA-cam channel
@@netts2315this isn't a television show
This guy is the shop teacher i always dreamed of having but never did. I would pay to have him teach me stuff like this even now at 44 years old! A person with this knowledge and ability to teach in such an excellent manor is absolutely priceless and rare.
I'm turning 50. Me, too.
UA-cam is a beatiful place to learn things in hobbies you like.
Amen🙏
Good news - he makes videos you can watch and its like being right there!! 😂
Sadly, they don't even teach Shop at my high school. And now the tradesmen
are in short supply.
I respect anyone who doesnt go "achtually one unit is better than the other" and just googles the simple question to provide both answers, but this guy went the extra mile and found a whole screw for using with metric. That's dedication to your craft.
Actually one unit IS better than the other!
... depending on the application. That's why you should use both. Both are great in different ways. Base 10 is good. Base 12 is good. Heck, Base 2 and 16 are also good, we wouldn't be talking to each other here without them. Number systems are pretty sweet.
From an engineering perspective, metric system is superior
Everything this guy says is intelligent and brilliant and i cannot get enough of this channel!!! Thank you!
I'm wildly impressed with how you changed those screws into taps so quickly. It's so obvious it's beautiful. Thanks for sharing!
Most welcome.
Tbh this method works but not too well, especially in soft wood.. I would personally drill a small hole (or route/chisel, whatever) and glue a nut matching the thread in..
I did this when i was 18 i needed a 5/8-18 tap to over size a damaged oil drain bolt on my car. Just took an angle grinder to a grade 8 bolt and i worked perfect. Its a pretty obvious idea
@@Simon-ho6ly Two of the stops displayed in the vid were made in the 90s, have seen moderate use for almost 30 years, and the threads are still serviceable. One was made from ash, the other from maple.
Use it in metal and it's a great thread chaser! Taps will often remove too much from a damaged thread but using a bolt with a slit will leave more intact (Also commercially available if you deal with that often)
I am a computer scientists by trade but I love this dude. He sounds like the dad we all need
So am I! Funny enough, I was just saying something like this to my wife the other day... He just looks and feels like a person I can implicitly trust with this. But also at the same time if he started talking to me about his days programming octal machine code, I wouldn't bat an eye 🤣
My dad specialized in databases and shit.
The sheer amount of drywall work and construction shit he had me do as a kid is wild
People who do a job like him, or you, developing logical systems and whatnot, have a relationship with logic and efficiency. This guy really reminds me of my grandpa who would always make a point to explain all of the usefulness of everyday physics in levers, pulleys and whatnot.
@@soundaholixx My great granddad built a house with his bare hands. Hooked up the gas work and everything.
Still standing 100+ years later, little worse for wear but just needs resurfacing.
The other day we were tearing down the garage wall, we found he used the straightest mesquite he could find around the farm, shaved them mostly square and treated them with his special brew.
Used motor oil and primer. Still sturdy as all hell, still holding up a second story with no creaks or shaking in the wind.
On the other hand, we've had to remove several uh... incorrect, usage of various gauges of wire, use of extension cords to run power underground to sheds, and the lack of gutters on both sides of the barn. (has lead to the south wall sloping at about a 12-15 degree angle) Some of the roof panels, being made of corrugated tin, didn't overlap correctly and probably led to some slow leaks into the walls over time. Surprisingly no mold, but our county has always been pretty dry most of the year.
Some of the insides of the walls of the sheds had scorch marks around the outlets and exposed wiring.
Amazing and ingenious wood worker, but should have asked someone with experience in electrical work before homebrewing his electrical and roofing solutions.
The kind of guy that ran a successful graze farm for nearly 70 years, despite thinking that the reason his tractor lurches forward while shifting was because the shredder blade was "pushing against the grass" and not sheer inertia imparted on the shaft.
@@blackwoodsecurity531Love this story. Expected "my great granddad was perfect in every way," but instead got the truth about what he knew well and what he could've used a little advice on 😊
Can I just say this guy is a wealth of knowledge. And you can see his passion for teaching
Quality and precision are two of the reasons I made my own jigs and tools.

He certainly grabs the attention
You could also embed matching nuts into the piece if wearing out the wooden screw thread is a concern
There are threaded inserts just for thatpurpose. Or, as another viewer noted, you could use Heli coils. I like the threaded wood, however, because it provides sufficient friction for the screw to stay where you want it. The screws get looser with use and age, but if you shoot some Chair-Lok into the hole to swell the wood just a little, it tightens up again.
The amount of precision lost as wooden threads wear is minimal, but for longevity, agree. Eventually the wood will wear (esp. Just you use a tap as a bolt), and you'll soon have a 3/16" hole and your machine screw on your shop floor.
Use a similarly threaded bolt dropper and replace your homemade tap with a new screw.
Then again, if you are into hacks, as this guy is, then before you drive your homemade tap, drill a 3/8" diameter hole (typical nut for 10-32 bolt takes 3/8 in socket). Drill 3/16" deep. Then, hammer in a 10/32 nut.
For that matter, save time and energy by avoiding making your own tap: first drill 1/4"completely through the stop. Hammer in a nut on both sides, as per above. Voila. No more steel on wood threads. Doubtful your nuts will ever spin or wear.
Coils good, too. But again, hacketty hack hack.
I’ve never heard of someone “tapping” a wood hole before.
Embedding a nut is far superior.
Doing it this way will also minimize the margin of error when the wood expands or shrinks
I just randomly saw this video with no prior interests in woodwork.. now im subbed and ready to build a cabinet.
This is 4/4 of these shorts that are short, to the point, and informational. And they are well produced. This might lowkey be the best channel on UA-cam.

That, ladies and gentlemen is a master of his craft. Bravo.
This is the best pro tips for woodworking I've seen on UA-cam so far!
After watching a dozen or so of your videos, I would love to come and spend a couple of weeks just watching you in your workshop. Of course while you narrate everything 🤗
He is so smart. A National treasure
We don't need more smart people, we need more considerate people. Because of the way he teachs gives us comfort, that itself is priceless.
@@CHICKENNUGGET69360 He's a good man. And thorough.
I hope many ppl see this channel and carry on this knowledge. Too many trades die out or knowledge disappears because were obsessed with college
and it's the people knowing trades that actually get jobs, while all those kids with social studies and philosophy degrees end up working for starbucks or on wellfare
I'm so glad this popped up in my shorts. I don't do any sort of wood work or carpentry, but I absolutely love this man and content. This is what I signed up for!
This is only the 2nd video I've seen of you so I'm assuming I'm gonna get flooded with them now real soon.
My Uncle has several patents for tools and he owns his own shop. He doesn't like to stop till he comes up with some new much simpler or easy to use a tool to do the job, most the time for much cheaper.
He is one of the very very few people I respect and to this very day I think the most precious moment I've had with him, he was giving me a tour of his workshop and we were discussing how cluttered it was. He mentioned that he knew he was full of junk. . . I mentioned that it wasn't junk if it still had use and he just lit up and told me how thankful he was to hear that. . . And now I'm crying.
You have such a nice voice, idk where I’ve heard your kind of voice before but it feels so nice and calming, just super welcoming and charming
He sounds like the actor Curtis Armstrong to me lol
hes like a real life gepetto from pinocchio
He sounds like the voice you hear when you're staying up late and fall asleep watching TV, then you wake up, hear this guy, watch him for a little bit, then the calming effect of his voice makes you drift back off to sleep.
I'm certain his lineage must have some gnome in it.
Danny DeVito when he talks calmly
He doesn't only have an enormous amount of knowledge but also the rate ability to present it in an interesting and memorable way.
Finally someone explaining in metric too!
Two thirds of our audience thinks in metric. It would be a major mistake not to include both systems.
I love you so much for thinking about out of US viewers and integrating a metric system advice ! I'm very low on money but very interested in woodworking, using my old grandpa tools, and those DYI tools tips like that are a blessing for me, thank you so much !
Most welcome. And metric isn't just an afterthought for us. Two thirds of our global viewers are meterminds. The fractionophiles are in the minority.
I consider this the best solution to the issue of emphasis, solving all the problems that arise during the production of work. I made one for myself and am very pleased with it. Thank you, buddy.
Most welcome.
A screw, or anything with threads, gives you infinite adjustability! You sir, are a legend!
Really appreciate that you cover both Metric and American Customary units.
I am happy that you never forget about the rest of the world, and then you explain us in metric system as well....thanks a lot !!!
Most welcome -- but you should know that the "rest of the world" is two thirds of our audience. It would be a massive mistake for us not to include metrics.
I'm a blacksmith, and this also applies perfectly to what we do. People tend to want rustic looking hammer Mark's everywhere, but in truth have to put them there intentionally! 😅
I took a shot at blacksmithing a couple years ago, and I was shocked to see that the hammer produces a flat surface!
This is by far the most well composed informative UA-cam short I’ve seen. Jolly good show
I just found him and from what I've seen he is an EXCELLENT teacher and knows what's worth teaching about the given subject. peerless man.
Good show, Jolly good show
He's been around for a long while. He does a bunch of tips and tricks for Shopsmith owners. Always twirling his hammers. 😆
In a million years I never would’ve thought of this idea. Definitely using this one! Thanks.
My late dad was a professional cabinet maker. I inherited his enthusiasm and a small part of his talent.
One piece of his advice I've always found true is that many jobs are worth building a jig for - and few jigs are ever a waste of time.
As for precision, I once showed a lab technician how to make a microtome from a fine-pitch machine nut and bolt and razor blade - admittedly only half as precise as the device from his lab supplier but a tiny fraction of the cost.
"Homemade tools can be as precise as professionally machined tools, if you build them out of professionally machined hardware."
What a good lesson.
Used to be a machine tool repair tech, and have some machining experience. The ability to compensate for your tools is what makes a craftsman.
I work in optics. Precision for is is measured in microns, this is the main technique we use to achieve it. Great advice.

What you do is absolutely amazing do not stop it unless you can't
This is great. I was a woodworker for years but I switched to being a machinist. The “precision tools” they sell to woodworkers are morbidly overpriced for what they are. This guy is right in the sense that when you use accurate parts like a machine screw which is more than accurate enough for woodworking of any kind you can build something just as effective. You have to think like a machinist to make things like these or just watch videos of other people making them. Trust me, you’ll save yourself a boat load of money in the long run. You’re not just limited to wood jigs/fixtures too, aluminum can be cut and shaped with all your woodworking tools that use carbide teeth. Get yourself some taps and and a good set of calipers and you can make anything you can imagine without paying an arm and a leg 🤙🏻
This then relies on the precision machining of the machine screws- which is likely extremely accurate haha. Great tip :)
Hey. Most machine screws are made with precision in mind because they are usually meant for prefit applications, meaning the hole they go into is already grooved so the threads have to be manufactured with millimeter precision. Also, most machine screws are fully threaded; the threads extend the entire length of the screw so it further lends itself to the applications suggested in the video.
Also with use the wood will wear. but you can probably throw some glue or resin down the hole and tap that to get more rigid threads. Also just make one of these fresh everytime. seems you really just need some scrap wood
yeah... he didnt really make anything precise... he bought a precise tool.... a machine screw. btw it will totally wear the wood over time and create slop.
@@Domieboy glue a nut to the end of the wood block. Now it's metal on metal.
Another of Nick's brilliant tips! Fantastic sir.
Woodworking aside, you need be in a movie. What a beautiful character!
Any tool you make yourself not only increases your own skill but will end up being some of the best tools for your skill, and will naturally increase in quality as you do, unlike store bought
One handy trick to make this better is to use a permanent marker to color in one of the six sides of your hex nut so you always know you made a full rotation.
You really know your stuff, thank you!
Welder fabricator here. Glad I ran across this, can't wait to try some of this... would be nice to see ideas for something like this jig that's versatile and portable
