- Sunday Notes 2 is a focus on physical senses in the shop, while operating machines or tools, showing an example of the search for a suspected problem developing and catching it before major damages accrue, on our Wilton belt sander.
One of the joys of being your own entrepreneur is being able to do preventive maintenance when necessary. I'd report things to our millwright who would submit a requisition for the parts, then be turned down by the front office as "not need." Keep up the good work, with well working machines.
Absolutely great attention to detail. You are the man.
After installing the belt sand we can hear some noise under pressure. Thats normal and much more better than befor. Thanks allot for sharing us these moments
It makes me feel a lot better to watch experienced craftsmen work and see that even they don't get snap-rings/circlips off in one try
I totally agree. I just replaced the arbor bearings in my Unisaw tablesaw which was making a slight growley noise. Come to find out the bearings were packed with sawdust and were starting to lock up. With new bearings in the old cast iron beast she purrs like a kitten. I try to keep my machinery running smooth. Thanks for the video Keith.
Excellent video. Thank you, I didn't even notice the hour go by.
While watching I was thinking how a power tool can get progressively noisier without notice until that one day is sounds like crap, and then you mentioned that in the video. It's a happy feeling when you bring a machine back to like it was when new and say, wow that made a big difference.
Sunday Notes is a great series!
When I'm checking on how the CNC machines are running at work I always place a hand on the machine, I can feel how the tools are cutting and whether they are getting worn, I don't need to stop the machine, open the door and take a look. Great video as always Keith.
Sunday sander surgery, with Dr Keith Fenner. Glad to see you made it through the storm. Just a little snow and wind here in southern VT, I heard it was bad down on the coast.
Keith teaching us how to be "touchy feely" ;) Awesome video as always.
So nice to watch a machine repair video at normal speed with real voice descriptions of the work, thank you Keith :)
Great stuff Keith! Thanks for another great video, Cheers, Doug
Nice catch on the designed to fail bearings, before they ruined the shaft or bearing mounts.
Great to see your Manual Machining, Welding & Repair videos.
Thanks for taking the extra time to film this! Thanks for sharing all the satisfying parts of doing the job right.
I just enjoyed a quality 1HR of master machine repair/rebuild. Thanks for all you do for us Keith... "you the man". If it ain't broke don't fix it is pennywise pounds foolish. You just saved an expensive quality machine, that you can now be sure that it will be there to get the big jobs done. Hats off to you again.
In my very young days in the navy, there was a saying: If everything works all right, and nobody knows why, Then you don't dare mess with it.
Great new series. Thanks
I had to chuckle when you caught the tub of imitation white lead and ended up with two fingers in it. Never fails either fingers in the can or upside down on the floor. I need to do an overhaul on my big belt grinder soon hope it goes as well as yours.
Funny you mention things you inherit from your dad. Those grinder nut come lock ring nut pliers you have. My dad has a pair exactly the same that I have never seen in Australia anywhere else. His pair were brought back from Italy for him. Something, amongst other tools of his I was told that were to be kept in the family. I’m sure most of us that enjoy your videos, can relate to with similar memories.
My dad was in the navy and did a mediterranean cruise, might of got them there or at Hughes aircraft. ;{)-------
Thanks for your new series. Nice to sip my Sunday coffee and watch an interesting video.
Excellent video and I now see why these bring the money they bring extremely well built
Lovely job of the strip down & rebuild nice to see a real craftsmen at work
Enjoyed watching from one tradesmen to another here in the uk
Nice job well done, had issues with teaching investigation techniques to senior technicians overseas 😉. I always use new grub screws when fixing hubs to shafts as the grub screws loose their cutting edge.
Nice repair Keith. Good for another 100,000 miles!
Enjoyed the Video,its a shame about the Bearings!Your audio is pretty good ,we could hear the Storm outside!Hope you make it thru without any storm damage.Thanks for sharing!
I enjoyed this in particular because the first of your videos I ever watched was your overhaul of that bench grinder many many moons ago.
+1
(...and because some call me perfectionist, or worse, when not accepting bearing vibes and wobbly shafts and brandnew tin machines in general when I can get a used cast one ten times better after a little love.)
the second time I've watched you replace bearings on a machine. Both were foreign made. Good to see we can make improvements and make them better machines.Thanks Keith. Say Hi to Vanessa for me.
I do auto body repair and have for many years, when a cars wheel bearing is damaged I can feel it when I drive the car. Yes I have also learned to use all my senses when repairing a car.
Nice work, Keith. I am in the machine repair business. It is amazing to me how many short cuts the manufactures make just to save a buck. Down the road we are replacing parts that should have never been a problem. For example several manufacturers' have made this machine and no one has found a way to make it without almost total dissemble to replace the belt. Crazy!
These machine rebuild/maintenance vids are some of my favorites, I get as much or more satisfaction from bringing a quality older machine back to like new spec. (or better than new in this case) than just opening a box from the store - though that has its moment of satisfaction as well-lol I have a little Delta home use model disc/belt sander and its showing signs of acting up, looks like im gonna have to do the same procedure though I dont know if the home model is worth it or if parts are even available - no harm in taking it apart for a look. Enjoyed the video, thanks Keith-!
Thanks Keith, I am looking at buying one of those Wiltons or the Jet equalivent, so now I know how they are built. I like this series keep it going. Thanks again!
That sense/gut feeling, that sound, that thing that tells us we want to go home tonight will get us there. It has kept me alive for a good long time and I hope it continues to do so. Good show today my old friend. Look at you now with 105K subs. Well done fella. Yer famous bud !
Wow, in order to remove part B one must first remove parts C thru Z. Great video indeed, thanks for taking the time to show....Ken
When you spun the bearing on the disc end and said, _Oh yeah! That one sounds good, don't it!_ I laughed out loud. You cracked me up.
Enjoyed the excellent and educational repair. I always liked to have on hand a couple of adjustable link belts in my work truck just incase I would get in a pinch and break a belt the took some time to change like on your Wilton and some equipment that had a drive shaft running thru the belt from a crank pulley to a pump like some of our old graders. (Austin Western)! Now that's going back a ways.lol. Thanks Ed K Cleve. Oh.
One thing that I admire is your reaction to Murphy's Law in the shop. My reaction is to spew a stream of expletives and yours is to chuckle and laugh. You seem to have life in perspective and I will strive to be more like you when Murphy makes his appearance. Yet another great and informative video. Solve the problem and get'er done!

Excellent points Keith. Glad to see it was a relatively easy fix to the senses.
i like the way you take care of your machines. Belt drive machines need to be kept in spec too "Getter Done".
Nice example of pre-emptive maintenance, always difficult to reduce the sound pressure (Noise), most of the noise is from the lapped joint, and flapping of the belt. I have had some success with inserting heavy density foam in a metal perforated case, close (within10.0 mm) to the belt inside faces and pulleys. Also some 2 to 4 mm sound deadening bonded to the sheet metal components. With regard to its Taiwan heritage, although part of China, but not the mainland, their quality is far higher, I have a XYZ bed CNC mill, USA control system ( now UK owned) mechanical builder is King Rich, and they have a strong following with great service and spares here in the UK. Again great channel and excellent content and presentation.
great fix Keith , Glad you got to it in time to save the shaft .. AWESOME !
Good catch Keith. Being in tune with your equipment and knowing when something is off can really save you a few bucks, injury or extended downtime. Same goes with vehicles or any other equipment. Don't turn the radio up to ignore an issue like the old saying goes. Great video!
I've got 16 employees, they never pay any attention to noises made by the machines. They've been told but.....
Very nice and detailed video. I'm not positive and I'm sure, someone will tell me if I'm wrong but, I don't think Wilton deals in machinery anymore. Only hand tools. I have a Wilton cold saw that was made in Italy. I needed a replacement part a few years ago and there were none to be had. I eventually found the saw several years after I made the replacement part. It was badged as a Jet and looks identical.
Hearing those crusty old bearings reminds me of the roller skates I had when I was a kid.
You do very fine work.
Regardless of bearing suitability that is sure a nice machine! You made it better than factory!
All that grit getting into a shielded bearing will do a number on your balls!
I've seen bearings freeze and the shaft starts turning in the inner race. The froze bearing works like a lathe and turns down the shaft pretty as you please. Thanks for the video.I enjoy this series!
The rain added a nice ambiance.
Great job Keith! I love this kind of video.
Pretty cool video! Awesome how fast you did this repair. When you say that you have 40 years of experience, I believe you because we have the proof right there.
I like particularly the sound take: I watched the video with my Sennheiser studio headphones on the head and I was feeling like been there in the shop with you. I heard the rain falling but not a noise coming from somewhere to guess but really over the top.
Great video, only thing missed was resurfacing the platen.
Very well made. Shame about those bearings. Looks like its sorted now and will give you many more years of service. Great video. Cheers
Great video, hope to see more of these on the sunday specials. If you look after your tools they'll look after you :-) keep up the good work and getter done !
Awesome video, as always. I really enjoy watching this, among the other machining related and videos you make. If I had a chance to apprentice with you, I would devote my time to being the best machinist I could be, as I see you have. The quality you strive for is amazing and you do it
Well built belt sander, lots of cast iron, I was equally impressed by the same era wilton band saws, built like a tank.
I worked 35 years as a mech. cert. welder, and machinist in a coal power plant, I also learned how to use my bodily sences to trouble shoot machinery .. Very rearly di they fail me.. Wisconsin Bear good video..
Solving the world's problems one job at a time...sometimes even your own.
Good stuff Keith, enjoyed!
ATB, Robin
Loving it! Thanks for another great video.
Big improvement! Good ear. Thanks for the video.
home bakes cookies, a fresh cup of Joe and the Fenner Show, best Sunday of the year , so far.
i agree, a short cut thats hidden deep in the machine. ya wont know it till its too late.
thanks Keith
you forgot the growl lol. Thank you. This is one of them times when if it is not broke don't fix it does not apply.
I watch everyone of keith"s videos especially his last 7 partner the boat forks I was impressed on how much tooling or setup was done way before he started to fix them. As far as the belt goes for The Wen I thought it was a poor design in having to remove so much of the machine. I don't know if all of the types of machines r the same way
Very good! I sure did enjoy this vlog Kieth.
Nice unit Keith, I have a Comet sander/grinder I found on Craig's list on similar design as yours, it appears to be built in same factory as the Grizzly and I even got a few parts for it from Grizzly that fit to a T. I also have a Grizzly table saw and 16" planer and have been very happy with them, they are also made in Taiwan. While looking at Delta and Jet at the time they are also made in Taiwan but at a much higher price and the quality is comparable so it was a no brainer for me to buy the Grizzly. Love the videos!
rayman954 maybe you don’t know but Wilton is own by Jet. I have at work a Wilton (like Keith has) and a Jet belt grinders and are exactly the same machines.
I have seen the same situation with bearings on many machines I own. mine are woodworking machines but the same issue with dust and trash assures the bearing wears out long before it's time. I always replace the bearings with plastic sealed bearings and the problem is resolved.
I enjoy your new Sunday series!
I would have replaced the upper bearings too, while the machine was apart. Never Seez is difficult to remove from hands. But an excellent product. Many thanks, Kieth.
I did the upper bearings in my true grit videos. ;{)-------
totally agree, that's this way tha I acquired most of my equipments, worthless for many, totallyn recuperable for me, this way, I acquired all my woodworking equipment. a brake lathe, a valve refacing grinder, a drill bit grinder, an engine lathe , an industrial compressor, etc...
Couple 1/4-20 tapped holes in the belt drum for a puller and the judicious application of a hole saw to the cabinet to make an access to the disk guard bolts might be a couple handy upgrades. :)
DAMN Genia - you had to completely disassemble that thing. :)
I find myself bobbing my head from side to side to the intro. music.
You might consider car wax on the cast tables to prevent/ slow rust on the machined surfaces.
Thanks for the vids
I have found Boeshield T-9 to be perfect to protect and make slippery all my metalworking and woodworking cast tables. Sprays on, and dries in minutes. Does not transfer to wood so staining/finishing is not ruined. Comes in a spray can.
keith, this series is brilliant, I am so envious I don't have a shed of stuff to pull apart, refurb aand rebuild like you.
Go grab a belt sander from Harbor Freight and you, too, can have that 'Doesn't quite feel right' sensation for the rest of your life.
living in uk we have the real estate, not the outlets and ups take 3 days....................but the sentiment remains constant
I gots the shed and stuff, c-mon down!
Eddie the Grouch 😁
I listen to the sounds my workers are making in the other room and know if I should check out what they are doing 😀
You make it look so easy!
Nice fix to get out af a gritty situation.
Excellent as ever! 👍 Maybe tip for the next rebuild/service (if you can remember in 10 years 😁), welding the nuts at the undersite of the base, so that your can remove and put back the boults withn ease. 😁
my thought exactly
I like this series.
A shame to have to do a full tear down to service those but lucky all the bores and shafting was still good so you could easily get it back in operation. Seeing that rack of t-slot cleaners reminded me you got any 13/16 and 1-1/8 ones to fit my machines? :-)
T slot cleaners? I thought that was the job of a screwdriver and air nozzle.
great video , thanks ,,
Left hand thread, oh you got it... Never mind... 😂 great work Keith 👍 definitely agree that rubber sealed bearings were the best choice, the shielded bearings lasted a while though
you have taught me so much! thanks
Excellent, keep'em coming...
FWIW I have the same machine except it is an older Rockwell/Delta made in USA unit. It is a beast IMO especially for my home/hacker shop :).
For anyone with a similar machine that has a problem with the belt walking (often a "feature" of cheaper belts) a single layer of duct tape placed in the center of the rollers helps tremendously in overcoming this issue. The single layer creates a tiny convex drum profile that keeps he belt in the center more easily.
I would love to hear what anyone else might have to say about using a vacuum or other dust removal for these types of sanders/grinders. I hate having the metal dust flying around yet I don't know of a good way to employ a vacuum considering the particles are potentially flammable????
I wonder what that fine metal dust would do to the vacuum over time. Maybe screw up ITS bearings?
Sense of touch!
after cleaning the surface rust off the table.. you might think about using some car wax on it to prevent additional surface rust.. my brother would do that to his rockwell table saw.. everything would just glide across it.
Oh great....Now I gotta go check out the 2 similar ones I have.
Great lesson for everyone thanks
I too think of dad when using things I inherited.
I suppose white lithium grease would do just as well.
Or Cosmoline type which is a waxy grease I think.
Thanks
Only someone like you would decide to completely tear down their sander on a Sunday.....I guess that's why I watch all your vids.....and I learned that "shielded" isn't....
no bolts or nuts left over mean did not put it together right. ;)
The only thing I would change would be to use a straight edge between the rollers to check the table (with the too short Allen bolts) so that it is neither proud or recessed and fully supports the sanding belt. It is a shame you had to replace inappropriate bearings that probably only saved the manufacturer .20 $ in cost that the purchaser would have paid anyway.
All that's left now would be the two ball bearings in the motor. Then it's all new again.
I did check the feel and sound of those bearings, and looked the motor over good, being a 3 phase the quality was pretty good. ;{)-------
Instructions to change bearing: simply dis-assemble entire machine.... Looks like the same procedure just to change the belt too!
Did you buy that sander new? It could be possible that those bearings have been replaced before with "whatever is on the shelf". I see things like that all of the time. I am actually impressed that those shielded bearings hung in there for any length of time. That aluminum oxide grit can trash a bearing in less time then it takes to finish one job.
I mentioned in the video I was the original owner. ;{)------
At 12 minutes in, watching this quick bearing replacement escalate, I’m making a bet with myself about whether or not it ends up involving a fresh coat of paint =)
hi keith @ 18:19
i think i saw a washer/shim fall away....but i didn't see you replace it on the build
Wow that's the same sander as mine only difference mine is a Delta. looks like they came from the same mold wonder if they are related? Thanks for the great video now I know what I have to look forward to already did the top bearings.
