Oh man it's awesome construction! I think I will use something like this, thanks for share! Also for one side (bottom, I think) you can use one pair of bearings in the middle - more simple to adjust and cheaper.
It's just 1 inch square aluminum tubing, 8 skateboard bearings, 1/4" bolts with nuts and washers and an MDF block of wood for the carriage. I would recommend using a drill press to get holes for the bolts parallel and straight up and down.
I tried that too with skateboard bearings, worked great for about two weeks then the bearings started to break down and not spin anymore, because the way they sit pushes the bearings sideways too, then they break down. I just used the cheap skateboard bearings maybe the better ones would last. They have something like v groove bearings at lowes for sliding glass doors that work great for cutting just wood, but have to much play for cutting metal.
Thanks dood, fantastic video. Again v groove bearings cost faaaaaaar too much. it may have been done before but at least you shared it. I will be using this on my next CNC table build. Your the man.
+Paul Frederick You got that right. I don't know why V-groove cost so much, and 5 years after this video I am unable to find metric 8, 10, 12mm 90'' bearing for a decent price. poorman DIY linear gude is solution. Long live Alanator, someone unknown wheel invetor who invented this and poor man linear motion guide.
will this be strong enough to hold up a skill saw or a router over a 9 foot length with enough rigidity so I can make a slab flat. I want to use it to make a jog so I can use a router to flatten slabs for table tops and to use it to cut boards and plywood sheets square. it will have an x and y axis
the only problem is using aluminum without steel guids will cause the bearings to pickup any defects in the aluminum like dents or divits, good simple design for a budget for sure either way
No I haven't been able to return to my CNC project because of other projects I've been working on. I was commissioned to make a Tardis and I also recently got married and made a photo booth for my wedding. I hope to return to it soon though. I might try this on a smaller CNC project where there is less weight being pushing the bearings apart and won't wear out as fast.
@WildSideLittle Thanks. No it didn't move at all. I tried to get the upper and lower bolts as close together as possible. When I put the carriage on the square tube it was a little tight because it was pushing those bolts apart ever so slightly. I decided not to go with this idea only because drilling holes to mount the tube at 45 degrees might not be so exact. I'm doing 6 bearings now around a square tube that lays flat. I need to post another video! Time to get off the pot!
Awesome idea but is there concern with only the corner of the bearing in contact? I would think that it would wear a groove in the aluminum square channel fairly quickly.
Good idea! I think you should use steel because the aluminum might wear when you tighten them up for slop. My two cents. Or the wood for holding them might change size with humidity and there for more or less slop.
Hi friend i like the video .. i could use this system to build my cnc machine with nema 23 of 8 kilograms of torque? This sistema could work for a cnc machine to cut aluminiun 1/2 inches thicknes? I appreciate your help...
I was hoping that this would work but I think you are right about the wear rate. I need to find some inexpensive options for the CNC table I want to build for my everlast plasma cutter
I thought of this as well but the problem is mounting the whole rail... the angle is at the bottom and while it can be done of course it seems that makes the whole idea problematic... what was your solution?
I think it's a terrible design, I hate to be a little rude, but that surely wouldn't last long once you put weight on there. Even if the bearings are deep grooved they won't love the momentary load from running on such a slope. Also, the aluminium rail will just get chewed up really bad after you put weight on their and use it a couple times. The rail material should be harder than the bearing.
This method works as-is however add 40 lbs. and over-time this will will have issue quickly, the bearings need to be angular contact ball bearings but even those are expensive.
Crap - I don't know why your vid's aren't showing up on my daily list. :( Oh well - I'll just have to keep checking back! Anywho, that is freakin awesome man - good thinking on it and I bet it will last for some period of time - the track should wear out before the bearings.....
There is a better way to do this. You can make the bearings ride on the flat suface of your square. By using two L pieces one on top and one on bottom and just mount the bearings to that. Not my idea saw another guy do it. Looked like it would be solid.
With time your bearing lost precision because this type of bearing is not for angular force. this solution is not for long time and high forces. but is a low cost idea!
Took me 10 years to find this amazing video, well worth the wait
this maybe the simplest idea but work well, champion at this cost and performance.
super super super heart touching idea thanks for sharing
Thank you so much

Good, what type of bearing? Thank,s

Excuse me... what´s the ticknees of the tube.... and what bearings did you use ? Excellent idea... congratulations!!
Great idea! V groove bearings cost way too much.
only thought is that you have all your bearing mounted on points. so you wear rate might be high
per russ25052 - same thought
I was hoping that this would work but I think you are right about the wear rate. I need to find some inexpensive options for the CNC table I want to build for my everlast plasma cutter
Great! Very easy to build! How did you adjust bearings to avoid backlash?
excellent design !!!
Thank you! Cheers!
Sweet! I was looking for a simple gantry solution for a new studio camera stand I am thinking of making!
I thought of this as well but the problem is mounting the whole rail... the angle is at the bottom and while it can be done of course it seems that makes the whole idea problematic... what was your solution?
its not poor, its awesome for accuracy and strong !!!
I'm thinking about pairing a CNC with my everlast plasma cutter but I would only be using it as a hobbyist so I'm on a shoestring budget.
Very nice idea indeed. Kudos for creativity
Hey, that's cool. That would work with aluminum angle as well as square. (even less material).
Food for thought.
What about dimensions of this wood peace and what size of this screw and net and bearing ?🤗
Great, simple and totaly functional.
Did you use these on your cnc machine. Did they work OK, any problems. It seems a good solution as v-groove bearing are pricey.
Keith
Sir does it work in curve tracks?
Thanks for the question. possibly yeah if you get some flat steel bar and curve it and put a hinge in the middle of the carriage I bet it would work.
Cool, I am going to try this, where is a good place to buy the skateboard bearings?
I think it's a terrible design, I hate to be a little rude, but that surely wouldn't last long once you put weight on there. Even if the bearings are deep grooved they won't love the momentary load from running on such a slope. Also, the aluminium rail will just get chewed up really bad after you put weight on their and use it a couple times. The rail material should be harder than the bearing.
My thoughts exactly. Those bearings are gonna get chewed through in no time flat. A for effort though.
Hey, good Idea. What size and kind of washers or spacers did you use?
Thank you so much
This method works as-is however add 40 lbs. and over-time this will will have issue quickly, the bearings need to be angular contact ball bearings but even those are expensive.
Brilliant!

0:22 cat required for cnc, thats what the second "C" stands for.
Great and beautiful idea
Thanks. It was just a regular small washer for a 1/4" bolt.
how do you adjust it for play?
Simply awesome!
I think I can use this for a camera slider setup can you please lit the parts that you used :)
your cat was hunting something :) !
how u make adjustments?
Superbbb👌👌👌
Thank you!
very smooth
Macaulay Culkin, are you ?
What is this bering model?
Genius!
Thank you!
Трубу фрезировал?
Нет не молотый. Я купил квадратную трубу в магазине.
Thanks
GREAT IDEA!!
minh dang can cam on rat nhieu , viet nam
@WildSideLittle backlash is eliminated on your lead screws!!!! This is your gantry rail.
saved the day!
square iron bar slide
smooth cat
Hi alligator.
Thenks friends for video
Thanks!
Фигня все это, подшипник работает на ребро ,он быстро сделает своё дело
thanks for the vid ,iam going to tray
thanx man i did it you can see my videos on my channel
I decided to spend money and buy the real deal...
I got mine from VXB.com. 100 bearings for $45.
che bel gattino!!
SUPER SUPER
at the park!... ;)
GENIAL ...
=) el gatoooooo
