You, sir, are a joy to watch. I learn several things in each video. I appreciate your frugality and ingenuity.
Oh wow, that's a huge difference. I mean, you said ( i think the last time you talked about this jointer) that the motor was loud, but i had no clue it was THAT loud. :))
Another improvement would be a noise optimized opening.
On professional planers, the opening between the tables where the cutter head comes through is more of a comb than a continuous mouth.
That way less air gets trapped between the cutter head and the table edge thus generating less noise.
That’s so cool. Big shout out to the guy who bought you that conical cutter head!!
You should hook up a Kill a Watt power meter and measure the two motors, especially when jointing a wide piece of hard maple or oak. The induction motor might be capable of pulling a lot more than 1 HP when the slip angle is high.
Kill a Watt?!? Apparently you haven't been watching his videos on Raspberry Pi based current monitoring! Much better data from those.
Many continuous-duty motors have no problem to deliver ~3 times the nominal power for short amounts of time, although this might be less for a single-phase motor then for a three-phase motor.
And of course, this is not the case for motors that already have a dubious horsepower figure. There's a large difference between a motor that lists a continuous duty output shaft horsepower, and a motor that lists a short time peak electrical input power.
@@mlindholm Wouldn't that be overkill for just making a quick test? He's used pi's for years but it's not like he threw the kill-a-watt into the garbage bin once he started using it
@@Koushakur Same same only different - multiply by the voltage and it gives you all the dead Watts you need.
@@marco23p Yes. The motor Service Factor is how much you can go over the rated continuous HP.
The noise of the cutter head is generated when the straight knife passes the infeed table. One way would be to make a bigger gap at the table. But this would bring other issues. That's why a lot of planers have a toothed edge on the infeed table. That decreases the noise since the knife of the cutter is no longer passing by a straight edge.
Yeh I was thinking that, the cutter head is like an impeller stirring the air up and creating pulses of air that are just god awful
As a citizen of the BIG SKY I consistently applaud ALL citizens of CANADA. You rock. I have a RIGID planer jointer that I am very proud to own, but yours sure looks like it can go the distance.
Amazing difference. Always love your shop project videos.
All your videos just make me smile. Thanks for them all.
I love watching your content .I Have been watching for years now and learned a lot from you thank you.
Great video. I love that you work in your slippers and your problem solving abilities are excellent.
Massive difference!! Great job! Isn't it great to have such nice helpful folks!? 👏👏👏👏
Fantastic work, Matthias! Nicely done! 😃
Your ears are going to thank you!
Stay safe there with your family! 🖖😊
I just love the sound of big induction motors. Thanks for posting!
Good seeing you at work again Matthias.
Finally, great upgrade! Building of this jointer was the first thing I saw on this channel, and fell in love with it. I thought how great it would be to build one, just with induction motor and maybe even with helical head :)
Beautiful job sir. It’s nice to see all the other tools working together to fix the other tools. One big happy shop. Make On Brother
these are my absolute favorite videos of yours (where you're doing some kind of woodworking engineering on your tools), a return to form :D
I like that table saw maneuver. It's either mad table saw skills, or just mad. Not sure which.
Cutting freehand on a table saw like that will catch up to you, I simply don’t care who the operator is. I’m a professional woodworker who used to do that on occasion until one day using that technique hurt me bad. It happened so fast I didn’t know what happened for the first few seconds after it happened. Impossible to see it coming and prevent it, even if you think you have reflexes like a cat.
Best of Woodworking AND Engineering. Right up my alley. Love it.
your videos & content is always interesting to watch + you learn quite a lot from it 😀
keep up the amazing work Matthias 👏
Watching you lay out the belt gaurd was very satisfying. Thanks for the content.
Nicely done. Love your execution of projects.
Pretty ingenious. Going with a wooden pulley for the new motor was brilliant. Much quieter. Very interesting video.
I love your machines. Excellent result on this one! You'll have the best home built jointer in the world when that head gets in.
You are a genius. I've never considered a wood pulley, and truing the pulley right on the motor. Neat!
Been thinking this video was coming for quite some time. Really good upgrade!
Hey Matthias,
really nice video! I have been waiting for this one, and I really like the result. Looking forward to see the next video about the upgraded cutterhead.
Greetings from south Germany
You're an inspiration, Matthias.
It's always pleasure and inspiration to see how you are able to overcome obstacles in your projects :)
Awesome video. Can’t wait to see the new cutter head when it arrives.
I'm excited for the swap out of the cutter head 😊
Time for me to get busy. Thanks for your inspiration. "want" a bandsaw and jointer. Pretty ambitious for a 70 something.
Brilliant work as usual. I need to buy some plans and make one of those.
Awesome show today Matthias..
I remember you found teething the table to be unneccessary with the old design. It might be time to reconsider this now.
That said I am surprised 1hp is enough power for this. I would have guessed one would need at least 2 hp to keep it going nicely, especially with broader and harder workpieces. My 10 inch jointer has a 2,5hp three phase motor and that is plenty enough, although I haven't dared to take off more than 1,5mm at once with anything wider than 5 inches.
Thank you for sharing and nice work as always.
Greetings
Also Matthias
Been thinking of this for my jointer since the first startup.
amazing, you are a teacher, greetings from Chile
Homemade pulley, with a rigged up lathe with a piece of firewood for a tool rest. All the while wearing fuzzy slippers. Another excellent video! Thank you!
that wooden pulley matches your woodgear brand perfectly
nice job!
Washing machines also use belt and pulleys around those sizes, could be a good place to source parts
Exactly what I thought!
You will love the Sheelix cutter head. They rock.
Impressive and inspiring as always!
What a solution!! Excellent stuff
You are such a pragmatic and practical man, it’s just a pleasure to watch you tackle a problem
What an improvement!!
Excellent. Sounds like a real jointer. I would have been tempted to make the bottom pulley convex so its self centering. Not sure if that would have worked. Looking forwards to seeing it with the new cutterhead.
What a difference that made!
Exelente, más potencia le hacía falta para un mejor Desempeño.. saludos cordiales de Cancún Quintana Roo México 🇲🇽 bendiciones..
I know engineers that could learn alot of you. Keep it simple and dont overthink everything.
I just replaced head on my Ridgid planer and my oh my does it cut nice. Just be prepared for a very slight "scalloping" due to the individual carbide cutters.
Very clever and ingenious
I was expecting an idler pully, but your solution was elegant!
McMaster does indeed ship to individuals in Canada; they have been for a couple years now.
This Old Tony is going to have a lot of fun with this video. LOL!
My one thought on the new setup, is whether a link belt might be better, assuming you can source a cheap pulley for the cutter head. With the length of that belt, might see stretching issues.
Great video, as always.
The old motor does sound cool
Next items in his bucket list are :
Induction motor made from plywood cutoffs
V belts made from scrap pallet wood
Amazing work btw, I am a big fan of his work.
I am always amazed by your ability to asses and correct problems ! One more informative and entertaining video !
Hey Matthias, McMaster-Carr does sell to us north-of-the-border sweaty masses. Their shipping is super fast too. Not free, but sometimes it’s nice to tap into that massive catalogue.
Always improving 👍👍
Thats gooing to be one heck of a jointer in the end
Thanks for another great video! I still want to make one of these.
A helical head ($$$) would run quieter and give a longer lasting smooth cut. Most of the noise now is from the three flat blades slapping the air so when you turn on the dust collector, you are now slapping turbulent air making even more noise.
My couch potato quarterback opinion 🤣
A good source of ribbed pulley's and belts is the automotive industry. A quick trip to the local wreckers (junk yard) will provide an amazing range of pulleys.
Also, very interesting that the sound of the cutter head is amplified with the dust collection on. I am guessing it has something to do with airflow over the spinning head.
Those tend to be the next size up in terms of rib sizes. Also, none as big as I needed.
Yes, might be an interesting video in itself on silencing machinery. I hate those bloody universal motors, I don't know how Matthias has tolerated that one for so long especially inside a house. I wonder how difficult it would be to sound insulate that universal motor.
@@jefflormans5441 universal motors are small and bloody fast. Once those cutters are hitting the work the noise difference is a wash. Most universal motor noise is the brushes on the commutator. Planers are one tool I use ear protection operating.
It's like the spinning impeller blades rapidly block and unblock a sound chamber making it effectively change size. Think acoustic guitar. Maybe some strategically placed sound-deadening mat such as Dynamat would quiet it a lot more.
@@jefflormans5441 Worst thing about the Dewalt planer is how loud it is. Ugh!
2:30 I am going to make something out of wood. Liked! Great as allways! Thanks for all the nice videos! Greats from Germany
I have been watching you for years and didn't know you are in Canada
These are such good videos
I've seen adjustable V belts at stores that are adjustable but not sure how effective those would be for you. That motor looks about the same size as my 1hp Delta Unisaw bullet motor from 1944 and oh boy do those things have a lot of weight behind that 1hp!
Ahhh. Now it sounds like the jointers I used 50+ years ago, in high school shop classes.
I watched your shop filter I use the thin furnace filters and a old sheet as a pre filter
Well done as usual! I was curious to see if the new motor drew more power from the larger pulley or went over it's factory rating? (I'm not criticizing, this is excellent work)
You could add an idler pulley to the belt also.
That wedge lock system looks like something that would be very reasonable to make completely out of wood for anybody with a lathe. Specifically the ones that don't mind using it. Would probably beat any of the other wood pulley fastening methods out there as well.
Like the idea! Although two things concern me:
1. the strength of the wood will probably not suffice to endure the high pressures at the key
2. Using hardwood (which seems the most logical thing for me to endure the stress) for the cone part on the motorshaft may result in rather large movements of the pulley due to shrinking and expanding.
Do you have any idea how to work around that? Otherwise I might actually try it one day, even with the little grooves for the v-belt in the pulley.
@@franzsadler1429 something like Baltic birch plywood could give reasonable hardness while a theoretically being more stable with regards to movement.
Heaps better on your ears. Thanks for sharing
the reason that the jointer is louder with the dust collector on is because the knives force air pulses through the gap and turning the dust collector on amplifies the amount of air in those pulses. very similar to why blowers are sometimes added to sirens to make them louder.
It’s always satisfying when a gear puller works perfectly after fighting for hours with a hammer
It’s amazing how much quieter that is now. Also interesting that it makes more noise when the dust collector is turned on To me it sounds as though the cutter head makes more noise. I guess that’s the air flow passing over the cutter May also be that the air flow is being pulled different directions over the cutter head as apposed to just the cutter head pushing the air ?? Lol
Matthias, I ordered your box joint jig plans. but to make that had some other stuff to finish. Finished a wood extension to my table saw, make a new box / stand for the table saw, now thats built my out feed table is not the way or size. So ill build that table out of solid hardwood, then im gonna start working on the box joint jig. My next thing I want is to either make a 12" planer or 15" have not decided yet. Ty for showing this stuff its amazing!! :)
12" is plenty. It gets difficult keeping really wide tables flat.
@@matthiaswandel ya I honestly thought that to. My father , and I just sat here , and re watched this video he was in awe you made it. I said dad this is the dude I learn all my stuff from haha.
when you use that kind of belt (serpentine belt),you have to put a rogue pulley in the way.best place to install that,is the middle of two pulley,a bit to left or write,just make sure its on the circuit.(go to the near car repairing shop,you will find all this tools in perfect condition).
i love your works.
Super motore a induzione 👍
I didn't realise how used to that sound I was after all these years, great improvement. Looking forward to the next upgrade!
Now it sounds much more like old factory-built jointers I know. Not so much about noise level (but reduction is significant), but also about a "tone" in which it hums. From angry wasp to bumble-bee.
Nice upgrade! It might also be possible to reduce noise from the cutterhead by modifying the table. Some jointer tables have a row of small gaps instead of a straight line at the edges facing towards the cutterhead. As far as i know this is also meant to reduce sound from the cutterhead by giving the air more room to escape when the cutterknifes pass the edges of the table.
Concerning your motor: why is that motor so big having only 1hp? When you presented your fathers selfmade tablesaw, it also had a motor that seemed to be really beefy for the 3 hp it has.
You made a series of really interesting videos about induction motors. If your into it, I'd like to see you adressing this topic of motor-build-size in connection with hp in another video eventually!
HP is a measurement of torque and speed, this is a low speed motor so it has crapton of torque instead.
Older technology. Thicker wires and thicker insulation, lower temperature ratings, stator/rotor made out of materials that saturate at lower field strengths, older understanding of how magnetic fields should be shaped in a motor. all of this combine to require a larger frame for a given power rating.
Also, larger overengineering factors too.
That motor could probably run at 150% indefinitely.
My grandfather had an _ancient_ 5 HP motor running his air compressor. It was about the size of a wine cask, and 3 times heavier.
But, it was still happily running a century after its birth.
Let's see how many modern 5HP motors are still running 100 years later.
McMaster-Carr in Canada: go into any fastenal and they will cross reference any MC part number. About 90% of the time they have an equivalent, and its usually a fraction of the price.
you could always drill two apposing holes and tap them, then you'll be able to use two long bolts to "press the pulley off"
Merci

A tuned resonator (tube + bottle) near the sound source may reduce the noise level
With how long you've been at it and all the workshops you've had through the years I'm surprised you've never gotten into any metalworking.
One of the great mysteries of the universe: Why is Matthias saying, "Ah shit," one of the funniest things ever
😢 Ouch. McMaster is so convenient for projects like this. Their online catalog interface is the best I've ever seen. Sorry to hear they don't ship to you in Canada.
McMaster-Carr - - - Maybe its time for you to rent a post office box (or one in a place like a UPS Store) in the nearest US border town. :
My big takeaway: Cutting that taper in plywood freehand on the table saw.
nice improvement, tinnitus sucks!
It's interesting how much louder the spinning blade gets with the dust collector pulling more air past it.
-MarkupCenter- , I mean McMasterCarr, does ship to residential as long as you're a registered business/sole proprietor.
yes, but you can't register new accounts
@@matthiaswandel I think you can - you should double-check, I just placed an order a few months ago and had no issues. They can be expensive and shipping is always a surprise cost - but it's never outrageous. They often are the only place to get some things. And I like their CAD models which can be imported (and 3D printed) for prototypes! Of course, the wooden pulley is more fun!
@@matthiaswandel Surely a US viewer would be willing to receive and then ship it to you? I'll volunteer if no one else will, but I'm in Texas. Someone closer to a primary border crossing probably makes sense, like Michigan.
@@matthiaswandel I'm in Ottawa and have an account. Happy to help out if you ever need.
These MMC comments miss the point: if MW just bought what he needed, he wouldn't be MW, that's just not his style. The whole reason we're here--1.7M and counting--is that he doesn't just buy stuff like the rest of us schlubs.
You should consider putting a tensioner pulley on your belt, it'll help with the belt flopping around.
Браво ,сега вече има високи обороти 👍
Very nice!!!
I guessed you would make wooden pulley as soon as you mentioned putting a bigger pulley on. Believe me, it wasn't a stretch of the imagination.
Reminds me to your sirene build :)
indeed. The air getting sucked past the cutter head, with the blades interrupting the flow, is quite similar to how the siren works!
