A better surface grinder attachment (for belt grinder)

[@bwillan]

Jer, you may not make many videos in a given year, but the ones you do publish are outstanding in their simplicity and elegance. The engineering and fabrication community on youtube could learn a lot from you.

[@lsdave]

100% Been following Jer since before the belt grinder. He is SUPER talented at design. Lots of people building stuff on KZbin, but few builds are as elegant and clever.

[@nirgosh]

Great design, great explanation of the design considerations, every bit has a reason to be, choice of materials, stress testing... Amazing work man!

[@calmeilles]

Everything @bwillan said. It's *always* a delight to see what you produce, Jer. ❤

[@MariusHornberger]

What an amazing idea and build! Proud to be a long-time Patreon supporter of yours. The whole grinder has been on my to-do list for a long time. Finally, I got the space to build it. And hopefully I can do it with TIG as well

[@Jer_Schmidt]

Yessss!! I can't wait. Thanks Marius!

[@b5a5m5]

I hope yo u make a video of it! Always excited to see a new one from you.

[@AquaPeet]

Marius!! Another one of my favorite engineers :D

[@CosmasBauer]

Wow this is amazing! Especially the infeed mechanism. I love your belt grinder design as a whole. It is so well thought out!

[@Jer_Schmidt]

Thank you!! This means a lot coming from you (I'm a big fan of your work too)

[@rcbax434]

I worked in the high-speed packaging world for over thirty-five years, with hands-on experience; with some machines spitting out pieces at over one thousand a minute. Over that time I saw some awe-inspiring stuff and... things I would not connect to electricity. In a career spanning the time I did you get to know and appreciate innovative and amazing ideas born of and from a place of creative genius. I admire the thought and the well-executed process you possess. I know what I'm saying is worth exactly what you paid for it, but I am just amazed and awe-struck at your creative spark and ingenuity... Just pure genius!

[@musamor75]

You have echoed my very thoughts, except I don't even have your experience. I'm sue you must have seen a hell of a lot of machinery and mechanisation. Therefore your comment carries plenty of clout.

[@charleswelkie265]

You reminder of the old adage, "Perfection is our goal; excellence with be tolerated". Thank you for sharing your designs and thought processes with the rest of us.

[@cristinaperez5757]

glad you are back!! all the support in your journey, we see you

[@ellliottt]

Here, here! 👏🏻

[@virtualburton]

agreed! you do you.

[@christianp3388]

Wish you well. You be you.

[@mikededmon]

Same! Hoping you're doing well. Here to support you in any way I can. This new table is really cool!

[@6rilllir6]

what are you talking about ?

[@mcremona]

2025 will be the year that I finally build one of these

[@Jer_Schmidt]

👀

[@alonsorobots]

If I could do it as my “learning to weld” project, you certainly can do it too!

[@MichaelJeffers75]

I bought Jeremy's plans between 1-2 years ago. I really like his design with the only exception of the rigid forward facing idler bracket. So I copied HouseMade's pivoting idler bracket to make a Schmidt's House remix. I favor having more option than is needed because one can never predict the future.

[@AlwaysBored123]

That flex mechanism for the table is mind blowing. So simple and elegant.

[@tonywatson987]

Simple, sturdy, accurate and elegant design - but a LOT of deep thought has obviously gone into eliminating backlash, chatter and angular misalignment. Well done, Jer!

[@2handsomeforlaw]

You are making the world a better place piece by piece ❤

[@tooolboxx]

I don't have the equipment nor the shop to build any of your projects. But I thoroughly enjoy watching all of your videos, and have been doing so since I happened on your first one years ago. I have re-watched several of them, especially your cabinet build. It is nice reading all the comments and knowing that your work is appreciated.

[@guillermo7777]

I have been watching ever since you build a concrete work bench and the storage cabinets, your videos are one of the best on carpentry the good old days and now the belt grinder machines, keep them coming, Jer greeting from Santa Cruz bolivia

[@BSpinoza210]

Jer.....Jer.....you realize what you've done here, right?! What this will mean for bringing precision, surface grinding, metalworking for the home shop, and the variety of projects this will open up for even home making? I no joke think you might have revolutionized the market for basic shop and industrial machinery. EDIT: OMFG JEREMY, YOU BUILT AN INFEED RIG ON A MACHINE WITH A FLEXURE, ZERO BACKLASH MOUNT?!

[@mumblbeebee6546]

Between yourself and Matthias Hornberger you invent more useful stuff than I could ever have hoped for. Not just invent - _develop_ anticipating user comments, testing assumptions, getting data to back up your designs… Truly nice additions to the Hammer and Lathe :0)

[@mbfhh]

My god, you're amazing. Watching this made my night. The extreme torture test for the flextures was astounding-definitely you get the, "beyond a shadow of a doubt" award.

[@superordinate]

You've done the work of an entire engineering team! You are superhuman, Jer!

[@MrJohnnaz]

Genius, best half hour on You-Tube I have seen in a while. Tom Lipton would love the use of those flexures.

[@jamesdownes1974]

So many clever design decisions here. I’ve not seen anything like that parallelogram flexture before. Excellent video as always, Jer!

[@JackmanWorks]

Great to see you back again Jer

[@jayoliver3734]

Fantastic work Jer. I’m always appreciative of how thoughtful and in depth your videos are. Between you and Marius H I have faith the future of practical engineering is in good hands. Cheers!

[@mattw7949]

That build montage was the most satisfying ever. Those money shots of the parts laid out on the table with proper OCD orthogonality and proportional spacing made my day.

[@DrJuan-ev8lu]

Yes, not only is the design ingenious, but documentation of the build is award winning. Clear and to the point. I notice many have commented how they appreciate and enjoy watching his videos ... even though they are not into knives or metalworking.

[@jaredrattray]

Your gen2 belt grinder has already taken my workshop to the next level, i use it all the time, but this is going to be a game changer! I cant wait to build this. Other projects be damned, this is up next! Thank you!

[@grilsegrils9330]

How much material cost and work hours can be expected on this tool. Is it a 2000, 5000 or more expensive tool/machine?

[@jaredrattray]

@grilsegrils9330 I used scrap steel where possible but I think maybe around $600 total and that included a set of wheels. I used an old motor i got for $50. The scrap yard is your friend.

[@alexrains1893]

Jer, this is absolute genius and the perfect accompaniment to an already incredibly considered design. Thank you for all the care you put in and for being so kind in sharing your work to your community. We Love You.

[@alexrains1893]

HEXAGONS ARE BESTAGONS!

[@revilolavinruf]

Honestly, I'm blown away. When my home made grinder no longer does what I need, I know what I'll be building! most versatile grinder I've seen. And it feels I've seen 'em all!

[@kurtbilinski1723]

Another very well thought-out and versatile accessary from Jer - well done, sir! Plans ordered!

[@BombasticVirus]

omg i dont even do metal working and I watch every vid of you and you always make me be amazed how perfect your machine is, you literally time tested the parallel mechanism. i sure want a machine like yours one day if I were a company that produce tools I would 100% hire you on a full time job just for you to be around and develop your ideas for tools in your out time frame, even if we wont use that tool for sales

[@solarguy6043]

In my view, quality beats quantity every time. I know the YT algorithm likes more frequent releases, but don't change anything. Your channel is great as it. This is, hands down, the best DIY belt sander on the internet. This is also better than most commercial belt sanders.

[@kramerdesign9443]

Unreal, Jer is still showing every other 'maker' on KZbin how it's done

[@garethwyatt626]

You have the nicest comments on KZbin and well deserved. We need more videos 😅 another fantastic design and video. Keep it up

[@myahmitchell]

Another great video! Always get excited when I get notified about one of your new build videos!

[@cdamianidis]

Subbed for woodworking and will likely never touch metal, but my god i love your videos. You epitomize an engineer. It tickles me to see you test and prove. The amount of thought you put in leaves me in awe.

[@dasroteklavier-svenhaarman9262]

I cant cheer that enough. Great work, would love it in my workspace. Im very impressed again. Im a pianobuilder, precise work is my daily business. Greetings from Germany.

[@monkeysausageclub]

I only thought the other day I'd not seen a video from you in ages. Always worth the wait. Great bit of engineering.

[@B-SPOKE]

Jer, as to be expected of you: a well thought through piece of kit. Well done sir. Also, thanks for being mindful on metric folks.

[@Evolucion7]

Another beautiful, extremely well thought out, addition to the best belt grinder any has ever designed. Excellent work, as usual.

[@2dividedby3equals666]

To call this great is a huge disservice. It is very clear that you don't settle for anything other than as close to perfection within humanly possible. I've said this before and I'll say it again, you're one of the most talented people i've seen. I hope to get there someday! Thanks for sharing and take care!

[@Demasx]

The thoughtfulness of the design and explanations is a pleasure to watch

[@bmay8818]

I love seeing what really smart people come up with, so it makes me happy every time I see something you've made. This is an excellent design!

[@josuelservin]

I really love machines that can help make themselves! And making something complicated is really easy, making it simple is so much harder, and I appreciate the elegance of the design.

[@WISPAH]

Great to see you again! Hope you've been well.

[@kylebija]

You even made metric plans! You think of everything! Love your channel.

[@benkilgore]

Every time you post, I am blown away. Use of the flexures to remove backlash is pretty clever. It would be interesing and informative to see some measurements of the results you can achieve with this.

[@thisquietplace]

These videos are always on another level, great job! Hope you're doing well

[@hanshans387]

I bought the gen2 plans ages ago and this is the kick up the butt i need to finally fabricate it, thanks Jer! I'll get the surface grinding attachment when it's available too, it looks awesome!

[@Therapistinthewhitehouse]

Good to see a vid from you. I was only thinking about you the other day. Happy new year.

[@jorickferies2299]

Thanks for sharing your work, nicely done, i didn't realize the possible capabilities of beltgrinder yet !! Awesome job 👌

[@JulianMakes]

Beautifully designed and made bravo.

[@AlexA-tl6kg]

I have no need for a belt grinder but still LOVE these videos. Thanks for publishing them.

[@braincraven]

You are a most brilliant engineer. Nice design

[@theinfernalcraftsman]

Very nicely done. Great simple engineering design. The grinder is on my list of builds I really want to do.

[@erwinfleischer9586]

Jer i bought al of your plans , great work you do , my Grinder ,with all attachments work great , but with your new extension make it great again 😃

[@roBLINDhood]

Looks amazing!! Glad you are still making things and sharing them as you are very talented at both.

[@FareedHameed]

amazed at your ingenuity and attention to detail

[@Maker-G]

You forgot to say “if you can’t make it perfect, make it adjustable” but truly this just seems perfect. Excellent work, and thank you for sharing it with all of us ❤

[@woznaldo]

A really well thought out system. I love that you tried several prototypes and the final result is a marvel. Well played Sir.

[@TheHasix]

Hands down, this is the most versatile belt grinder ever. All the attachments, parts, and details are very well thought out. Thank you for your work ,truly inspiring. It would be great if you managed to get all of it into production. Good luck

[@andreaslundback]

Wow! What a masterpiece of engineering! As simple as possible and highly functional. I have designed (very much inspired by yours) and built my own grinder and it works great. Now I will for sure buy your plans and build this grinding attachment. Thank you for sharing and inspiring!

[@aaronbuildsa]

The flexure mechanism is just .. *chef's kiss* so elegant!

[@AquaPeet]

It's a freaking marvel of engineering. Heck, YOU are a marvelous engineer! :D

[@acraig5075]

Looks fantastic. I can appreciate the amount of time and effort that must have gone into this.

[@benkeller3]

I continue to marvel at your ability to make complex things simple. Thanks for taking us along for the ride. Bytheway your plans that I have bought are very well done.

[@mikebell611]

I ordered the Gen2 and other plans last week. After I get it built, I'll get these plans also. Nice work Jer. Can't wait to get this project rolling.

[@Chris-pb3se]

Excellent design and execution

[@bobnoxious1983]

Great Engineering Jer. I'll be buying the plans for my Gen1. It really is 1 of the best machines in my workshop. Keep making plans luke these every few years,it gets me back to my workshop!💪🏻

[@samvandellen3695]

I was having a discussion with my wife yesterday about the progression of skills, and how much more capable we are becoming in our various endeavors. Even your earliest videos showed an impressive set of skills, but you've clearly been putting everything you've learned so far to work, and the results are truly spectacular.

[@kpotter78]

Jer! You are a frickin genius! Thank you for sharing with us! I have been trying to find/design a decent and affordable surface grinder attachment for years! I bought your plans for the gen 1 grinder a few years ago and built it in my garage through covid. The only thing i don't absolutely love about it is that i cheaped out and used a treadmill motor for it and it bogs down and overheats quite often. One of these days when i get the funds ill out a good motor on it. Thank you for sharing your designs with the world! You are greatly appreciated!

[@109joiner]

Jer, you are one of my favourites, along with Marios Hornburge, Matthias Wandel, Pask makes, and a local lad to me, The Yorkshire Workshop. You are a great among greats.

[@carycleland9506]

Ever since building your grinder, I have wanted a surface grinding attachment. You have made my day. I will definitely be building this.

[@madshusdal2133]

Thank you Jer! The plans are looking fantastic!

[@jwil6902]

I’m always amazed at the incredible attention to detail you have in every aspect of a design. From the spark shield to the position of the reference pins on the mag chuck, you consider things that could and probably would be overlooked by other designers. Great work Jer!

[@tsstn]

Jer, I've been watching your videos for many years now. In fact I bought one Made in America, American flag from you to put on my own grinder, perhaps you remember. Your attention to the smallest detail is commendable. I truly wish more consumer products had your level of thought applied. You are simply brilliant. I have not yet seen a better or more useful design of a 2x72 belt grinder. If you could reproduce them en mass they would be the Hilti of Home Depot tools. The Snap-On of Harbor Freight. The best above the rest. Nothing really compares. Beautiful work Jer.

[@SnappyWasHere]

I love the explanation of how you got to this design and why it is this way as much as the table itself. Good to see you’re still building stuff!

[@andrewzimba7432]

Your designs are so well thought out Jer. Thanks! Order made.

[@AnonymesAss]

He dropped another video so I dropped everything else so I can watch it! Always a pleasure! Your eye for detail and precision is just a joy to witness! Greetings from Germany

[@tlanfer]

I love the flextures. So simple, so effective.

[@keithviolette5870]

Jer, great work again! Brilliant use of flexures for the fine feed.

[@youruniquehandle2]

Hey hey, Jer is back! Glad to hear from you again and another great project.

[@joewhitney4097]

Great addition to your already great belt grinder Jer. You have a fantastic nich in tool design. Keep up your great work. We enjoy it a lot. Thanks for sharing.

[@DrJuan-ev8lu]

Totally pro!!! Totally. And there were three things that really surprised me, the use of flex plates instead of machined ways, getting away with only one ball race carriage on each track and deep setting the magnets under JB Weld. Re the magnets: I thought that epoxy mix had steel particles which would partly shield the field. And I would expect better holding power if the magnets were right at the working surface directly in contact with the work. But I can see how epoxy fills in the empty spaces around each magnet to allow easy removal of debris. And JB Weld will give you a long wearing surface compared to the rare earth magnet material. Those magnets tend to chip and crumble. You did a great job developing this attachment. Bravo!

[@TalRohan]

Sweet design, very logically put together. It works so much better than any attachment I have seen for belt grinders. Your entire system is well worth building to be honest.

[@graemewhite5029]

I built my grinder a good while back after being inspired by your earlier videos, I can't believe how useful it has been. I also made a rudimentary angle table for sharpening the blades on our wood chipper, but now I have to upgrade it to this linear table as that will give me a more consistent grind. Thanks Jer.

[@NathanNostaw]

You have done a fantastic job on this design. Some great features and so much thought in every design choice. Thank you for sharing it.

[@AndrewJones-h3c]

Mate, bloody ripper, I'm in! I thought my Jer Schmidt belt grinder was good by itself. Can't wait to get to build this. Thank you so much for sharing your brand of genius! Dude, you need some merch stickers so we can credit you when our friends come to our shops!

[@sapelesteve]

WOW! Fantastic work Jer! Good to see you posting again & hope that all is well. 👍👍

[@veronica5896]

I just watched some of your old videos the other day because i love them so much! I love hanging out with you!

[@veronica5896]

Omg - you are a freakin genius!

[@QuestionsNotAnswers]

Fantastic design

[@tonywatson987]

That sprung pendulum parallelogram is a stroke of genius - no sloppy joints, perfect alignment over that short distance and rock solid! Looking forward to the in-depth video of the thought processes that led you to design that.

[@dansarfert3585]

Always a pleasure to see your minds work materialize. Stay well my friend!

[@tmpace9]

Everytime I watch one of your videos I feel like it's a masterclass for tool making. Fantastic as always

[@muledeerdude]

This is brilliant. I am very impressed with how much thought was put into this.

[@MattsAwesomeStuff]

Knocked it out of the park again. I love how we skip immediately to version 6, with what seems like decades worth of refinements to your design. You're absolutely meticulous in considering and optimizing every little possible thing. I'm glad there's people like you in the world.

[@Forexfox99]

Grinding mini cleavers and it doesn’t matter how I use my surface grinder I cannot stop a grind line appearing where I have to move the blade. This idea solves that problem. Well done!

[@peterwadham9788]

Another excellent product well done

[@mbfhh]

Voice sounds great!! I can only imagine you're applying the same over engineered perfectionism plus charm and humor there as your other endeavors. Excellent work on all fronts

[@joell439]

🎉🎉😎🎉🎉 Jer, Great to see you're doing well and still creating clever tools. I've really enjoyed building and using the Gen2 grinder and look forward to building this accessory. Thank you!

[@jizmb39]

Couldn’t believe my eyes when I saw you had a new vid up. Thanks for all you do. We all super appreciate your attention to detail. Glad you’re still here.

[@gsmith128251]

I have watched you for years now and you just keep amazing me.

[@tjkoker]

Jer, as always it is great to see that wonderful mind of yours at work. A great addition to the belt grinder you've designed. Can't wait for the final prototype and plans. Cheers!

[@eatenkate]

You are the person i try to channel every time i have to build something (:

[@mahinschatz]

I'm glad you continue doing this! Great Idea and great realisation as always. Greetings from Germany!
