Hey everyone- the most common question on this build is why aren’t there wrench flats on the arbor as well? You could do that, but it wasn’t needed for me because the arbor is in the mill when I install the saw. If I want to install it outside, I can hold it in the bench vise.
Another common question is why is the registration diameter on the cap instead of the arbor? Because that was the way that occurred to me to do it such that it would accommodate different saw thicknesses. It’s still less than 1 thou TIR this way and more than good enough for hobby slitting saws. I’ll never claim this is the best way to do anything, but don’t get overly obsessed with details that may not matter for your application, either. Things don’t have to be perfect to work and we’re just hobbyists here.
RED, ORANGE, BLUE, VIOLET, GREEN, BROWN, PINK, MAGENTA, TURQUOISE, YELLOW, GREY, WHITE
This is one colorful comment you might not want to delete.
:
I bought a really expensive super fancy pants .0004 TIR straight shank saw arbor from TMX, and it had the same design in this regard. The thread was actually a separate cap screw, but the registration diameter is on the cap, not the arbor.
Also, fun fact, I made the arbor from this video first, bought a fancy TMX slitting saw, and then the saw didn't fit. I thought it was my fault so I bought the TMX arbor and it turns out that the slitting saw hole was out of round 🙃 I had to go at it with a Dremel before it would fit on the TMX arbor. Yaaay.
Registration on the arbor vs the cap is a tradeoff between theoretical best concentricity and z height; easy enough to put a recess on the cap if you're willing to use a screw in it instead of threading it, but then the cap needs to be tall enough for the registration diameter to nest into it when using a thin saw. With it on the cap it can nest into the arbor where you already need material. I did it on the arbor when I made one, but I was more annoyed by runout than by clearance at the time.
“Because I’m a monster”. I lol’d.
that arbor genuinely looks like it literally wasn't moving. VERY impressive.
My grandpa made himself a caliper with brazed carbide point so he could scribe with it. I have no idea how, but he made it crazy precise. It's a family heirloom now.
Your design lends itself to being made double ended. Why not make the other end fit smaller sized slitting saws. 😉
Brilliant idea!
I agree!
I intend to make one with a Morse taper on the end such that it fits directly in my milling setup of an Emco.
That's not a bad idea until you think about clearance.
@@mattiaconti3682 I don't understand? It would be the same diameter along the whole length.
Pro tip for future you, stamp the wrench size on parts you make.
That's a good idea!
Or make them all the same size and paint the wrench Kubota orange. Damn spell correct.
That is A time saver....
That’s a great idea!
That's a great idea! I write the sizes on the tools, but stamping makes more sense.
For extra monster cred, use Whitworth wrench flats, and a metric screw thread, with your imperial shank size.
I think you just described my import 1985 Enco knee mill. Took some comments from the wizards of Practical Machinist for me to believe the combination of threads the machine actually has.
@@chrismorris8695 I own a lathe which uses metric and imperial screws and nearly every screw and bolt has a different head.
Some are slit some cross and some allen head.
@@Sven_Hein Are you willing to sell one of your two lathes?
@@ChristophPech I had connection issues and it posted twice.
Sadly there's no lathe for sale.

@@jeffdayman8183 I suspect she gets the Tappy Tap Tap line from AvE, but it could be the other way around. I also suspect she has been getting hand gesture cues from ToT.

I made the mistake of playing the "quality of life" drinking game while watching...every time Quinn says "quality of life" you take a shot....so now I'm 3 shots down in one video and so is my quality of life lol 😆🍻
Drinking games on my channel are frequently fatal. I should have a warning about that.

I will join you as a monster; I use my calipers in whatever they fit to be used for, one can always get new calipers, but not always a new scribeline
That's a win, I think it's the most concentric slitting saw set up I've seen, really nice work. All the best for 2021.
I was in training some 40 years ago. The person that trained me on the many machines that would work on wood all ways tell me in our set ups that for the quality of life you should do this. I always thought if I didn't do it his ways he would put a hurting on me. I would laugh. But now I see what it means in the way you used that fraise . I am impressed with you ability to teach. Thank you.
They're your calipers, so use them however you want! :)
And for us Monsters in training, your shot of the vise clearance at the end shows a way to hold round stock in a vise at an angle using a simple jig. This is by far the clearest example of a how to on slitting saw arbors I have watched so far. 2021, off to a good start.
I love your funny comments. Breaks my concentration but makes watching more enjoyable. Well done keep it up.
Because I am old, I tend to mess up order of operations and forget operations in a setup as well. I have taken to making a check list of everything I need to do to complete a part. While the documenting part is tedious and boring (no, not that kind of boring), it makes the machining part fun and carefree, not to mention my success rate has gone up.
I've not used a slitting saw yet, but have observed that most videos of them show significant runout which offends my OCD tendencies. Loved the project and seeing that saw run in near concentricity. It made my day. I can live with the imperial collet size and metric wrench for tightening, working on most things now days seems to require both systems anyway.
Thank you for posting this on my birthday. Nice present.
Happy birthday! 🎂 🥳
I really like the little projects you do that involve making tools and helpful shop gadgets. I mean, it is a total pyramid scheme of making tools with which you might some day make tools to maybe someday make useful stuff, but it is educational.
Scribe marks with your calipers! Yikes!!! You are such a rebellious sort... love it! Nice arbor tutorial. Thanks.
Bought a horizontal band saw for completing some parting operations that would have been done on the lathe. Life is so much better now.
No, we are not stuck with you. We come here by choice and enjoy the trip. Use your calipers how ever you want. They are yours. I have calipers that have been used for marking for at least 35 years and the points are just fine. It's not like you are gouging metal out. You are just scratching the Dykem. Dykem is pretty soft stuff.
But you don't want to mount the calipers in the tool holder and use them as a parting device. 😁
Quinn, you're not a monster. You're just a Canadian living in America, which means that you get to mix metric and imperial all day long. Please never change.
“Universal” usually means “One size fits nothing”🤔
Nice job on the arbor👍🏼
Lovely! I particularly like the 14mm wrench (spanner) flats on the 5/8" arbor, it's just the sort of mixing that I would do, and be proud of!
Yeah, people who complain about the continued use of imperial measurement are just those that can't handle *both*... :-)
@@Roy_Tellason speaking as one of those people...... aaaah.... you got me there.
Watching with my blondiehacks mug, coffee tastes much better.
Great job of machining and lots of clearance. I had the same crappy slitting saw arbor and made my own but not for the exact same reason as you. The saw would tighten the screw so tight I could not remove it. The first time I heated the arbor and used a pipe wrench and such to remove the screw. The next time that was not enough to move it and the cap stayed on. So I used an external thread with a nut, not as much clearance but I can get hold of it to remove it. I also put in a key for the saws that have a keyway. I hope you will keep us up to date on how your arbor performs and whether or not it tightens the fastener too much as I just might want to copy it. Thanks for the video.
I did the same thing and never could get the thing apart. Maybe Never Seize next time?
Many thanks to you Quinn.
On the end cap might be a cool idea to make a roto broach and broach a hex internally. Building the roto broach would be a good project as well as making your set of arbors out of tool steel and heat treating them and finishing them either with a tool post grinder. Of course then you would need to make either a nice wood case to house them in your tool box.
So enough with my content ideas.
Nice job Quinn.
Must be a monster too. Wouldn't know what to do without my trusty dial "scribelipers".
Continue to be a monster it is the feeling for the steel and creativity that counts. Something you have in abundance. An old timer from Sweden
That's pretty spiffy!
Thanks, and Meow to Sprocket.
The way we used to make similar was to have a counterbored cap and use a suitable Allen screw to hold it and the saw in place. That way you gain more clearance under the saw.
You're not a monster Quinn.
Mr Pete, however, once put metric threads to an imperial sized nut and that's just evil. 😁
I GET why people are mad about marking with the calipers. I really do. However, I still do it. I end up breaking my calipers by dropping them, or smashed in some other way before I wear them enough to matter anyway. This is why I keep a couple pairs of Starrett or B&S calipers around, so I can just keep working when I forget the calipers on the carriage and bump them onto the floor!
I left a pair on the gear change box of our tiny lathe. The carriage being power fed trapped it against the housing and folded them in half. Barely even loaded the motor.
You are a Wonderful person and you are on earth for a special reason.
Love your videos and your personality.
Dear Quinn, your videos have become a highlight of my Saturdays. Happy New Year for you and please keep them coming.
Gotta make one of these I ran into that clearance problem just the other day. Crappy arbor B-Gone!
Every arbor I ever purchased either tightened itself to death or instantly unscrewed itself. I want Hydraulic Press channel to crush them all.
Happy New Year! Quinn.
and let's hope we can add some "huge quality of life improvement" ourselves in twentytwentyone.
I don’t do metal machining, but I love watching your projects, thank you for the detail, humour and learning opportunities you provide. Happy New Year.
I've had a set of those Dewalt Extreme drill bits for quite a while now, they are great cutting tools. I can tell you that from my experience you can go straight from the centre drill to the finish size (note: the biggest I have is 13mm) without a pilot and without any complaints from the drill bit. Of course, the correct size pilot (must not be larger than the spigot) does reduce the load quite a lot. Stepping up through he sizes is just a no-no with these drills as without anything to hold/guide the central spigot, the drill wanders horribly. Just try the biggest one on some scrap steel and see.
Those slitting saws are great for all kinds of jobs. I have a little model builder's table saw that uses slitting saws, and I have a lot of those, so it was obvious that I needed an arbor for the mill too. I placed the mounting flange for the saw blade on the arbor so I could turn both faces in one go. I think this reduces run-out introduced by the screw type you made. No idea if this is really necessary but it works great. I also made an (extra) cap that consists of a counter sunk bolt with a fairly thin ring for clamping which allows me to get real close to my vise.
If you're a bad person for gently scribing with a caliper, then I don't want to be a good person. I'm still not sure why that procedure is supposed to be bad, and what the preferred method is. Have a good year!
I can think of a few reasons why it's bad but frankly I'm a great believer in do what works for you, I do similar with calipers.
The thought behind it being bad is because calipers are precision measuring instruments and your putting unneeded wear on a measuring surface. My opinion is it's only bad on nice name brand stuff like Mitutoyo or Starrett. I have cheap Amazon calipers I use for fast layout. You can get vernier calipers for under $10, which basically make them disposable.
Are people actually upset that Quinn uses her calipers for scribing? The internet never ceases to amaze me.
I apprenticed almost 40 years ago. My master would give us apprentices a hefty slap on the back of the head whenever he saw one of us abusing the calipers as scribes. Times have changed and prices for calipers have come down along with prices for various other implements used in measuring semi-precise features. I won't gripe too much when I see Quinn use her calipers in a way that they were not designed for, but personally, I won't ever use my own calipers in than fashion.
@@lotharerkens8154 I understand why folks are not cool with using calipers for scribing but what is the practical alternative?
Great little arbor. Second time watching, thought Blondihacks was a "he". My apologies.
@@Nomadboatbuilding scribe.
Used my caliper to scribe a line this evening. Perfect!
Thanks Blondihacks, I enjoy the channel, have learned a few things and I appreciate, your honesty in showing mistakes. Cheers
Excellent job.
Peter, how are you.
Happy New Year Quinn! Really enjoy your work and attitude! I spent 31 years in the cutting tool business and miss it. Now I can get my fix watching you! Thank you!
Fresh out of High School I worked in 2nd operations in a factory cutting slots in the piece that holds the blades in X-acto Knives. That reminded me.
7:37 Let's add some colourful commentary: Happy New Year!
👍 I made my own because I wanted to be able to get closer to the center (depth of cut) and more height clearance to the arbor lower end. Plus I had the materials on hand and I'm a cheap bastard.... I bought about $2k, 40+ pcs, of NOS premium quality US and UK made HSS slitting saws for $85 on e-bay and made two arbors for them from 4140 - 1/2" and 1" centers.
I come for the puns and I am never disappointed!!
As to your wrench flats, there is a chart in the machinery handbook on acceptable standard tolerances for both fasteners and wrenches to ensure that all wrenches will fit all fasteners with acceptable grip.
As soon as I get my mill and lathe setup I think I will give this a go, just need to extract the machines from the packing boxes.
Perfect. I have a need for a 1/4” arbor and will follow your design. Thank you. 👏👏👍😀 Andrew
Thank you, will try it. Happy new year, keep upp that good work and you filming. 👍❄
Part looks great. I love this channel.
I also love how the caliper scribing is essentially troll bait at this point. I personally have a cheap(er) set of calipers I use to scribe all the time, and I have a nice set for actual measuring and whatnot. Keep the trolling coming and thanks again for the great content! I'm learning a whole lot watching your channel.
Everything I do is troll bait at this point. 😀
It's not troll bait. It's trolling. And a very public bad example that's permanently recorded and publicly shown to all future viewers.
At least she's not incessantly saying "Let me know in the comments" which seems to have taken over from "Like, share and subscribe".
@@XTL_prime Yeah, you're right. I'm not sure why I said troll bait. It's straight up trolling indeed.
Really nice project, Quinn. Simple, but elegant design work.
Well done, by the way, I have calipers that I would never use to mark material with and I have calipers that I would mark my material with all day long and never look back. Let the haters hate, it make their lives meaningful.
Happy New Year! Looks like a great solution. The more I watch your channel the more I want to be able to machine things to improve them but have too many other "hobbies". Maybe when I retire.
Thanks Quinn Happy new year
Sometimes, I use a section of a bolt instead of cutting threads. I Loctite it into one part so it stays put. You end up with rolled threads made of heat treated steel, so it is stronger than if I made it out of one piece of steel. Your thoughts?
Another low profile tightening method: drill 2 holes on the face of the cap and use a pin spanner wrench to tighten.
Nice arbor. So nice to have imperceptible runout in a slitting saw.
I once left delete-able comments, then I realized you actually read your comments. I stopped after that. Awesome video. I really didn't see any runout on your arbor or saw.
Thank You for making learning so enjoyable.
Hey I finally found another person who uses their calipers to scribe with though I mainly use them on plastic but I have used them to scribe some mild steel sheet metal
I’m pretty sure they’re YOUR calipers.....🙂
Love your video. Not a machinist so I have no idea what the problem is with marking with your caliper, but I'd venture to say you are not a bad person at all.
I have no training at all in your field but I sure like your video. Thanks for entertaining me.
Happy New Year Quinn. I enjoyed the latest video, as I have with all your work. Thanks for allowing us into your machine shop. Enjoy the year 2021 and be safe and well.
I bought something similar to this for my angle grinder, no idea why. It just looked cool.
It is literally terrifying.
Nice job! i definitely see one of these in my future!
Excellent work.
Nice work, I’ll definitely be trying one of these when I can get back to my shop.
Happy new year to you and your family.
Always useful are slitting saws.
ahh this video was...a cut above...and we all saw what you did there....but we arbor no ill will :D
awesome way to start a sat afternoon thanks Quinn
Quinn- I love your videos and find them very instructive. One of the things I personally appreciate is that you make “mistakes” just like those of us with who aren’t pros and you make it clear that they aren’t (usually) catastrophic.
PS - I also love the quick puns you routinely throw in.
Oh hey writing the blade thickness on the cutoff saw in sharpie is a really good idea. I learn a ton by watching how you work, in addition to the main theme of the project.
Learned new color today, teal. Probably one and only machinist in the world that use teal color. Thanks.
Hi Quinn, nice job and interesting video -as always - and nice to see the saws being used! I made arbors for my saws in a similar way, with dedicated arbors for every (inner)diameter in order to minimise their height.
A note on the saws, they have legacy and a history worth to mention in these COVID times, they were used for manufacturing prototypes for intensive care ventilators in the 70-ties (:
Cool! Thanks again- they have been super helpful. I’ve used them in many projects already
My American made Starrett calipers that test perfect against gage blocks again and again don't get used for marking, but my cheapos are constantly used for marking. The cheapos are good to within a thou and that is all I ask if I am using layout anyway. Tolerances are a beautiful thing. Your arbor has far better Tolerances than blades are made to, so you are golden.
Quinn, Please don't loop the sandpaper like that when you are polishing. It can grab and suck your your hand in faster that you can let go of it. Check Adam Savage's hand injury on tested from a few months ago for reference.
Never could figure how my (wood) circular and table saws had better designed precision than machinists' slitting saws. Yours is a good design, and you may have answered the question.
Nice video! Sometimes the best tools are the ones we make ourselves! Thanks for sharing!
Nice work Quinn, thank you...
Layout with digital calipers. Its why I buy Harbor Freight calipers. They are perfect for layout and if I am in a hurry I use my Mits
Happy New Year, Quinn, and thanks for a practical project. Les in UK
I very much enjoyed this little project. Thank you!
Faustian bargain.....lol...I still recall your xmas recital and chuckle every time. My wife quit asking me what's up...
Phrase of the day “quality of life issues” (-:
Oh you used your calipers in Arghhhhhpttth! Brown Green lavender Pink Chartreuse Mauve and yea Periwinkle!
Ooh, lovely! A nice tip yet again. Thank you and stay safe!
Old arbor "isn't going to cut it"...classic.
Of course those that get hung up on exacting semantics will not join in our fun with words because they will point out that it is the blade that should be doing the cutting...
Brilliant. Happy new year.
thanks! gives me a head start how I wanted to make one, if I get around to doing it haha. my hacksaw is urging me to do so soon!
Same issue, so I'll be making one of these next. Great video as usual.
Excellent, looks great
Happy New Year to you and Sprocket 😊
