Machine your own Low Profile Slitting Saw Arbor

This video shows one of many designs for a low clearance slitting saw arbor you can make yourself, and have forever.

Good design!
What I like to use as a material for the shank is case hardened linear shaft, it comes fairly straight and nicely centerless ground.

You give excellent info Joe, and I thank you. So here's a tip for you:
I use Heat treatment quenching oil as a cutting lubricant. It is designed to have a extremely high flash point so it doesn't smoke when you cut with it. I get it from Brownells and it keeps my basement shop smoke free.

One of those things that are obvious AFTER you see it done: The head of the cap screw can go INSIDE the bore of the tool. Thanks.

[charles]

very much appreciated especially pointing out the technical issues of what to look out for. - like the square inside corner at the seat of the saw blade and how you overcome the issue.
great work.

I'm really glad you made that comment at 3:45 about "chewing sounds". Despite making very accurate arbors ALL of my slitting saws run eccentrically. I suspect the manufacturers are not as careful as we are, tolerance wise, when they grind them! I'll make another one just to see if I can eliminate that effect. Cheers from NZ - your videos are the ultimate mentoring program for us hobbyists.

What a great tool holder!
Well there is a one advantage lets call it if you put long screw from back and make threads inside the cap.You can put a tailstock center if you are going to use a slitting saw on the lathe.That way you get rigid setup.
I know, i know slitting saws arent exactly a lathe tool but beggars cant be choosers and if you got milling attachment its a tool you can use if you are too poor to afford milling machine.

I have just about finished making the internal key, piston type as i have never seen one before . And then you show one ! I did not realise they were even available . Cheers .

[DCFusor]

Sweet one - I need to make one of these myself. Thanks for taking the extra effort to do high fidelity voiceovers. They really make these videos more enjoyable.

Great job, excellent machinist!
I love the way you completed this task with such precision, checking the temperature and cooling down the material. I worked for 4 years as a machinist on conventional machines, surface grinders, and CNC lathes, mostly handling technology, programming, cutting, measuring, and finishing

[johndevries]

I like how the low profile is attained by sliding the cutting blade arbor OD into the main arbor ID. This makes it robust and usable with varying thicknesses of cutting blades. Nice design, Thanks for sharing.

Thank You again Joe. I have to machine up an new arbor, for a new design I'm working on, and this Arbor design, will be a major help to me with this job.
Just a Dumb Question from me Joe, I'm a 64 year old, that has worked in my trade (Mechanical Fitter-Machinist (manual), etc), all of my working career.
I have noticed on a number of occasions in your Great videos, that when you are using a Centre Drill, to start a hole in material, that you drill into the material, so that the Tapered/Beveled section that the centre drill hole makes, is larger in diameter, than the diameter of the following twist drill (see at 7 Minutes and 10 Seconds, in the above video).
I remember back to the mid 1970's, where my Tech Teacher (Mr John Saunders), told me to ensure that the tapered section of the centre drill hole diameter, should be smaller than the following twist drill? Have things changed over the years, or does it make no real difference?
Best regards, JB, Australia.

Thank you, Joe! This is exactly what I was searching for for a hobby project! It's awesome that pros like you are willing to share this kind of thing.

[JanBinnendijk]

When i was much younger... (25) i came up with the same design.. and this design has served me very well over the last 27 years...the only thing is.. mine is a bit smaller.. but these tools pack a punch!.. Keep up the good work!..

[garthbutton]

Without a doubt I have learned more tips and tricks from you Joe, thank you for sharing your craft🤗

[timmerlives]

Love your videos Joe. Almost every time I use a slitting saw the nut is always in the way. Watching this build, it occurs to me that my level of “ machinist “ knowledge is very limited. Turning wrenches for cars... I got that. But machinist, I’m just a rookie. Anyway, that’s why I always respect any skilled craftsmen that truly knows their trade. You sir, KNOW YOUR TRADE !!

[jimad]

I never knew the slitting saws were hollow ground. I was gifted a bunch of them by the widow of a wonderful machinist, and I've always taken baby cuts fearing a binding accident. Makes my day to learn this!

[darkhorsestudios]

I've been watching your videos for years, and as usual, another great project Joe . There are so many people out there making videos regarding "machine shop tools/builds/how to's etc. yet only a few are good educators as well. Its a whole new level if you can put your content across in such a way that enables absolutely anyone to be able to understand what you're doing and what you're talking about.

I made one arbor similar many years back, and an old tool and die maker told me to put it into the mill and then true up the face and it will always run true, It definitely worker for me,

[RockingJOffroad]

Nice project! I know it is a fairly simple job, but as usual, your attention to detail shows !

1 addition. Mill flats on the shank so it can be held when the cap screw is being tightened with the extra torque it provides.

You are an Excellent Teacher Joe.
Thank you.
