With the new CNC router and its spoil board with T-tracks, I needed a new clamping system and had many very useful ideas.

Nice work. You could use a different colour filament for a different lenght of a screw. In that case You could quickly visualy see all possibilities even if they are mixed in one box.
Marius: You have an amazing creative mind. Thanks for sharing your ideas!
yea the play school colours are great from seeing in a box of parts or even on a messy bench
I was thinking the same thing. Red for shortest purple for longest [in ROYGBIV order] for the handles and bases or even just the handles.
Your creative problem solving never ceases to amaze me! The cross grain, the tiny magnets to hold the washer. Great ideas all! I don't know what your plans are, but you'd kill it in mechanical engineering. A little statics, and strength of materials class and you're off to the races. Or you could kill in in the trades/maker space as well. You're funny w/o knowing you're funny. You're great at explaining your thinking, and you're edits are spot on. You could be the young-Diresta! :)
I think Marius said in some of his videos that he was a mechanical engineering student. Probably got his degree by now.
@@con-f-use I remember an episode where he said there was a lot of schoolwork. But I couldn't recall in what. Thanks.
@@con-f-use yea I remember that too
thats great ! one soloution i thought of the spoil board is to glue a 6mm mdf top to 12mm ply that way you have the best of both worlds strong ply t tracks and a surface you can flatten
So glad you are back to uploading regularly for a while. Love your videos and appreciate all the hard work you put in!
I am late to the party here, but you can use a 50/50 mix of polyurethane and a thinner and then wipe on multiple coats to the slot area on the underside and you will greatly increase its strength and durability with minimal increase in size. Great work as always.
T-slot head bolts are available from e.g., Rockler. They're easier to use and, since the nut (knob) is now on the top, one bolt length is (usually) all you need.
Wouldn't you have the head bumping into the part that's sticking out with diffrent workpiece heights?
@@dennisbengel11 No, the head would be down in the T-slot. It shouldn't bump anything. Look at these clamps, then pretend the nut is on the top and the bolt head is on the bottom, but too wide to just pop out of the slot. You can buy those special T-slot bolts and they're made for this purpose. Google 't slot bolt'.
I took carriage bolts, ground the sides of the head, and it slides in and out easy and the knob is on top
Marius is one of very few people on UA-cam who actually makes 3D printed objects that are useful. Very clever and useful
Thanks. Love the ideas. I'm so happy to see your current videos back online.
Great engineering and top notch results as always! And such a nice young man too. Your folks must be so proud.
I always appreciate your content! You're skills at solving problems are impressive!
Great video. It’s nice to see someone who has the tools has the ability to use them as well as you do. Thanks for sharing.
This 3D idea it's amazing man congratulations nice work
Marius, It’s great to see you developing your skills in CNC and 3D printing, because I’m sure they will be valuable skill sets for your Engineering Career!
Fantastic problem solving - I love it
Fantastic stuff! I do enjoy your methodical approach and your ability to find solutions! Also I would use color to easily identify the length.
If you have problems with the MDF wearing out, you could make them stronger with some cheap aluminium flat profile. My guess is that 2-3 mm will really spread the load. You may have to recut the pieces of mdf tho...
use plastic
I would try stabilizing the MDF with epoxy. Since the wearing zones are just the borders of the tracks, a very fluid epoxy could soak into de MDF.
🔥
Nothing else to say. Mr. Hornberger, yet again, expanding the old game, by bringing in the new game, to make a better game for all. Bravo.
To reduce wear on your flat surface you can use the trick I use for mine, I just use printing paper. It's very consistent on its thickness, so I just place a few sheets under the wood so the bit eats the paper surface instead of the flat surface. If I have a very large project, I have a roll of butcher paper that I fold over a few times to make the thickness I want.
This clamping setup is definitely a well thought out solution that should cover a broad range of needs. Well done!
One thought to help with increasing the strength of the MDF would be to have your toggle nut and MDF spoil board clamped from above with a magnetic toggle nut and fender washer. It may not provide much strength since it is on the top but could delay it some since the clamping pressure would be stabilized and also supporting the MDF from the top.
your Engineering Education (along with your natural talents) is really shining through.... Congratulations!
Marius, I used very similar techniques on an Excellon circuit board router about 40years ago.We would often use tooling pins to relocate parts back on the machine for further processing. We also were able to ‘step’ larger pieces to allow accurate drilling & routing on work that was larger than the capacity of the machine.
I so enjoy watching you, you and my son are alike. You both have a mind that will take you far. Keep up the good work.
Oh, my goodness, this is fantastic! I will keep this in mind when I finally spend the money on a CNC machine. Marius, you have such a bright future in product design!
Future? You mean now....
Nice to have more content from you again, great solutions!
Wow. Awesome work Marius!
This is the true power of home 3D printing. Nice work Marius.
Your work holding strategies are incredible!
gotta say.. at 10:17, when you tilted the ramp up, I got emotional. What a great idea that you came up with! so many nice improvements!
If anyone can make a Corona-Cure it's Marius! We believe in you Marius! There is no problem complex enough if you put your mind on it!
So many options on fasteners and clamps, I like variety. I'm a fan of nylon and brass bolts/hardware when the job has small parts. I have a bad habit of running the expensive end mills into the steel ones on really tight jobs. These are always the last tool in that size that I have on hand for a job that needs to be done right at that moment.
You're a really generous, excellent maker-dude!
I think those are the best clamps ive ever seen.
I love watching your videos. Great job!

Your content is excellent Marius. Seems to me I subscribed to you when you had less than 10K subs. It is easy to see why your channel has grown so much and is so popular. Your creativity is awesome.
great stuff Marius! thanks for sharing all these awesome ideas.
So neat and beautiful at the same time! Great job!
I am really impressed. Amazing.
German ingenuity at its best, well done marius, good job ty
You have a wonderful problem solving ability. The company that hires you when you graduate will be lucky -- and I expect several companies have thought of that already.
If you use a knob with a long internally threaded shaft to go over a bolt that links into the table, it might allow a large enough adjustment range without tool path interference with short workpieces.
Very creative ideas and well executed. Good video. Thank you. Cheers, David
Absolutely fantastic mechanical mind. You Sir, are an Inspiration, a master of the magnificent! Good on you....!
Totally going to make this for my shop! I also use nylon bolts for the hold downs in case I crash the router. That doesn't happen very often anymore, but I run a shop at a school, so it does still happen with students' tool paths. I definitely recommend nylon bolts! They save end mills
That's a great idea!
Twisted minds think alike!
I wanted to make a few this weekend anyway for my new X-Y table.
Well thought out Marius, a pleasure to watch
I love your use of 3D printing to problem solve
Like the quality of your prints. You are a talented designer.
Nice designs and well thought out. Thanks for sharing!
I hope you're planning to manufacture and sell these. These are a great idea, and I'm sure some company will snatch up your idea and start selling them.
Even just an Etsy or Shopify. Patent would probably be a waste, if you could just beat the competition to most of the demand.
I doubt the idea is novel enough.
Sure, you could be a lawyer to make it looks like it's super clever and whatnot, but it's just a glorified ground nut
Great job! Already saved in my to-do list :)
Your magnet idea and demo is fantastic!
Your 'open end' idea is so efficient!
Your 'end grain' reinforcement is amazing. :)
The flexible heights is brilliant!
wow! This idea is really cool! Thanks for teaching me.
Simply brilliant. Don't let the tool companies Rob you of your idea.
Brilliant solutions. Well done.
This deserves a patent. Smart solutions.
Dude. That's awesome. You're smart af
I'd buy those for sure.
Those are beautiful tools. I even like the color choices you made - the orange and yellow goes well together.
Now you just need to machine the clamps out of aluminum and anodize them a similar bright color.
Maybe for the surface you could glue thin plywood on top of thicker MDF. That would give you plywood at the top of the track to take the clamping pressure, but the MDF would keep it flat.
Very good. Will try this on my 3018 cnc machine
Well done and well thought out designs.
Mega idee
Da hatte jemand schon öfter Probleme mit der Befestigung wenn du so kreativ werden durftest
Klasse Video wie gewohnt von dir
Bist n Bomben Typ
For the different screw lengths you could use different filament colors. That way you can know by sight which ones you need.
Great video.
Brilliant work sir. Very very helpful...
You need to patent all of that!! Brilliant!! 👍👍
Google “clamping set for milling machine”.
1-use studs of various lengths instead of of bolts. A threaded rod cut into small sections of various lengths is a good source of diy studs. You do not need grade 8 steel studs for clamping wood. You can buy knobs with pass-through holes. They work just like nuts but you can tighten them by hand. Or use nuts to lower the vertical projection of the clamping setup
2- there is good chance one of the standard size T-slot nuts commonly used by machinists will match your slots. They are not expensive and will last forever. Sliding those nuts in/out is not a big problem. But I in exchange for small inconvenience they offer large support area =great holding power.
3-the ramps need steps to prevent it from sliding apart under force. Look closely at the ramps used by machinists.
Very clever design
Pure genius, yet again 👍🏻
You’re a smart cookie. Good ideas and good video.
Very well done. Great ingenuity.
Very cool design 👍
great improvements, thanks for the video!
Thank you so much! Those parts are awesome.
genius - as always 😁👍🏼 great problem solving!
The technical term for the "spokes" is "knubbel". Awwesone Job.
Brilliant and great use for 3d printer
Very nice job
Turn the bolt over make a 3d printed holder/knob for the nut. Use a grinder to shape the bolt head like the drop in nuts. Then use the metal t-slot as intended. You made great 3d designs.
Great ideas Marius. I'm going to pinch that ramp slot idea for my milling machine clamps :-)
Amazing problem solving. I am always impressed.
The first think I thought was to: Put in a bolt, head first, shaved on two sides and use a wing nut. Then no issues with length. Another thought... use all thread (instead of bolts) and you can tighten from both ends.
Was my first thought too, but that very likely interferes with the tool path
This design is both simple and very effective. It just automatically works without the user having to try anything. Proper engineering.
You could get the benefits of a plywood base if you just glue MDF on top without losing too much Z-travel and still get the easy machining of MDF.
Awesome stuff Marius, great clamping system! 😃👍🏻👊🏻 ..... perhaps in addition to labeled bins for storing the bolts, if you had also printed different colored T-track nuts for the different thickness ranges they would be more quickly identifiable if for some reason you have multiple sizes out of the bins at the same time.
I always enjoy your videos, without question, BUT... you do make my brain overload as I take in what you've done, and try to fit it into what I would like to do! :o) Keep it up.
I have read about hardening MDF with alcohol-based shellac. Put it on heavy and let it soak all it will take. Since it is alcohol based, it doesn't cause the MDF to swell. Another option would be to apply thin strips of countertop laminate to the load bearing surface of the T-track.
Just a quick idea, if you get small long strips of metal or hard wood, you can glue those to the underside of the T-tracks. They can always be salvaged once you need to redo the MDF boards
Thank you so much for sharing your ideas. It's so refreshing to see a young man using his brain to the fullest. I know your parents are very proud! PS everytime you say sh** it makes me laugh. It's my go to word also! Thanks again!
Great project!
You are a genius!! In my personal experience (10 years professional use of CNC) the problem with MDF is that changes a lot in thickness over time and you always have an ugly CNC. 4 months ago I bought a new CNC with hard ABS and since then I never had to plane the surface and the thickness is constant on all the 4 meters of my machine. Maybe, as your cnc is small, you might not have thickness problems.
nice idea, thanks.
you could reinforce the underside of the tracks in the MDF by using thin strips of metal so the little yellow clamp will be pulling against the metal instead of the MDF.
lit!
just finished watching, these look really useful.. those clamping speeds are insane :O nice work
What do you think about (diy) vaccum holddown tables? :)
Hi Marius. If you apply loctite to a piece of threaded bar and the nut you can use through hole star knobs then the length of adjustment is above the table. Great videos, keep it up please.
I also thought about that but I wanted to avoid that method, because then you have threaded rods sticking out that could interfere with the toolpath. Now I always only have the thickness of the knob sticking out.
Very interesting video, keep them coming.

Nice job Marius.
Great work! Regards
Great job! Use HDF to replace the MDF. And you could have used different colors in 3D printing the different sizes.Then you could store them all in one place.
you're pretty awesome dude!
I would go back to closed slots cut in the clamp boards, and make enough of them to go on all of the screws. That way there are only two separate things; the stair, and the screw/knob/clamp board assembly.
If you add an extra wing nut under the current 2-spoke star and fix the work piece with them (rather than the 2-spoke stars) then you could use the longest screw for everything. You wouldn't need to worry about which length to pick.
Awesome design!
As you were doing so much manual work on the little wood pieces I was wondering why you didn't simply 3D print all of it... watched 1 min more and you came to the same conclusion ^^ Feels like I am watching myself working ;)
Nice problem solving 👍
if you want a better material for the bed, just use thinner pieces of the MDF type but get the denser material masonite and layer these with a very tough glue, making a much stronger material, the laminating multiple layers does make them tougher due to the material being used to bond the layers, and you can alternatively use other substances in the layers too, that have fibers or something giving more strength if need be.
You could also invert the design by having the bolts anchored in their printed tee-housing facing up, and then having through nuts in the clamping handles. Longer bolts would do for all the lengths required. Though you'd have to be aware of where the bolts are sticking up to stop the router head running into them, I guess.
You just said the reason why I didn't went that way
