When I made this video I had no idea so many people would watch it and of course very few people have the tools I have. *** As a result of your feedback, I am developing a simple and inexpensive method to balance your bench grinder. When I complete the project I will publish the new video for everyone. *** - บันเทิง
Wish flanges like that were available for purchase. Good work!
I just finished making a commercial version Glenn. Just have to finalize pricing and they will be available. If interested you can be added to a waiting list by sending me an email info@rogertoolscanada.com
@@LetsRogerThat I need 5/8" arbor. I hope you are making some of those. I will email you. Thanks!
@@LetsRogerThat I just emailed you about that. I need 5/8" arbor flanges. Hopefully 5/8" was in the plans.
@@GlennLaguna I’ll design them for you. Gilles
That was one hell of an impressive fix 👍
I truly like your threaded exterior washer, it is easy to do fine tuninh that way.
It all makes perfect sense to me. Nice trick.
First problem is that PAL grinder, but I do like your method of adding weights to the flange.
I was able to balance my Baldor by dialing in each wheel, a quarter turn at a time with no additional weights.
Interesting. But to do it this way and so perfectly you need a very, very well equipped workshop. Is there a simpler way?
Absolutely here’s a video with a much better method th-cam.com/video/F3fVgcvmex4/w-d-xo.htmlsi=j26bZeWTDhQbcZSm
Add another item to my list of things I've never done, should probably do but might not ever get around to doing... lol
But that beautiful workbench of yours deserves a great bench grinder haha
@@LetsRogerThat, I was considering putting my bench grinder on a separate stand, back to back with a bench drill.
also me, But somehow we seem to have time to watch these help videos... Thats my issue...
I typically use my 2x48" belt sander to do grinding. I did use a bench grinder before that. Seems it only gets used now to grind the tungsten electrode points. But this problem is why I never like using the bench grinder.
I like your fix. Making those hubs is a time consumer, but worth the time.
I watched one video where the guy ended up epoxying lead to the side of the wheel. He chased down every issue with the OEM manufacture having washers that made the wheels wobble.
Project Farm channel did a video on cheap to expensive bench grinders. The one thing I noticed with every one of them, the wheels ran a swash plate wobble. You would think expensive brands would have very well made wheels, and hubs to make them run true. I didn't see that.
I made a similar weight hub for my surface grinder. I saw an article on the internet about using an accelerometer and measuring the signal, but the author was using an antique audio signal analyzer, and they want too much for that tool on eBay. So I used my Oscope, but since the motor runs with 60Hz, and that noise signal is everywhere in the shop, the ~3600RPM vibration signal was washed out with noise that created all sorts of beat frequency harmonics in the scope signal. I even tried the FFT function to see if I could measure it. Anyway you would take the rms reading of the accelerometer signal, and run it through a spread sheet calculator putting the test weights in 2 different locations on the balance hub, and it would spit out a correct weight to put in one location to balance the wheel.
I remember watching all the videos you mentioned. And I tried analyzing the vibrations on my surface grinder as well. But in the end I designed and fabricated a new spindle for my surface grinder and purchased accessories from Sopko in the US. I’d reached the end of my ability to resolve the issues. It wasn’t cheap but my surface grinder works really good now. Thanks for your comments. Really enjoyed your feedback. Gilles
@@LetsRogerThat I watched your spindle rebuild. That fits part is still something I need to understand more about bearings, then this morning I ran into bearing clearances of C0-C6, seems most affordable bearings are C3, so sloppy.
@@f.hababorbitz anything better than what I got costs $500 and up per bearing. It wasn’t worth it for me as a hobbyist
"What you are going to need to do first is go to the foundry"
😂😂
I don't have a surface grinder, metal working lathe.
I just a man in a shed.
I hear you. Im in the process of making an inexpensive system that is full proof and requires no tools at all. I think you’ll find that more useful
Very nice work
Thanks Rusty
I see a lot of negative comments here, I think they come from lazy people without imagination who only look for what's easy. I bought a Dewalt DW758 8” bench grinder (USD$275 in my country) and it was a big disappointment for me to put it to work, it vibrated terribly. Worried, I began to investigate the reasons and solutions. I did it!! with just an angle grinder, a drill and a homemade belt grinder. I can't guarantee that the pieces I made were perfect with those tools but they do work perfectly, now I have zero vibrations and I am very satisfied! Thank you very much for sharing your knowledge, it was very useful to me. Greetings from Ecuador 🇪🇨
I’d wear a mask when facing the grinding wheel…lots of bad dust..
How to fix 100$ tool with 5k$ tool :D
😁 I should’ve picked that as a title.
Good explanation, but the average home user doesn't have the machine tools to make or dress the parts shown.
Yep you’re correct. Before I had all this stuff I made some but they weren’t as fancy. And they worked pretty good. Gilles
Wish there was a video where it didn’t require having access and functional knowledge of a machine shop.
Let me see what I can do for you Manny. Challenge accepted. Gilles
Hey Manny, here is a video that uses easy do it at home methods. Let me know if that helps. Gilles th-cam.com/video/F3fVgcvmex4/w-d-xo.htmlsi=L-M8Mb-ptGRSqXNs
@@LetsRogerThat Thank you very much! Much appreciated!
Hopefully you can find the part the gentleman mentions. But one place you can try is McMaster Carr in the US, they carry all kinds of stuff. Let me know if I can be of further assistance. Gilles@@mannyo2909
@@LetsRogerThat Thanks Gilles, going to start with just redressing the wheel and see if that helps at all and then ho down the rabbit hole of trying to find those flanges he mentions in that video, so far only can find a European seller and they don’t ship to North America. I appreciate your help and time.
Who has a surface grinder in their garage. Or a lathe.
I never thought I would but here we are. 😊
Otherwise buy 10k$ machines to fix 200$ junk. I rather not use a bench grinder.
Its like buying fishing gear. Buy a crappy real and a good rod. Then you gotta buy a good reel and good lures and a good tackle box. Tough for the wife to argue😁
