Step 1 - Linear Slide Bearings for CNC Machine

[ItsALLgoingDownHill]

Dude, I fucking love you.

So how do you tighten the slide? What about brinnelling of the ball bearings?

Isn't it easier to form a box slide.

take square stock that will form the way, and some slightly smaller stock that will form guide rails and gibbs. Take 2 of the rail stock and a drill hole at each end. Rotate stock 90 deg, and drill/tap 3 additional holes. Next get 2 plates, and use the end holes in the guide rails to drill holes that will allow a "U" section.to be formed.

@steveBB30 Make the inner width slightly wider than than rail+gib stock. Bolt last plate down on top, and tighten up until rail too tight to rotate, and is so constrained to slide/rotate between plates. Insert gib stock, and remaining holes take set screws the tighten gibbs against side of way , the clearance gap added between the guide rails, allows a little adjustment if you want to rotate the box a little, or loosen/tighten up the action. Don't need rails to be perfectly parallel either.

RPM on the drill is way too slow

[anajonesr]

@pardomtlca Thanks. I've gotten way better tools since then. :)) However, the RPM may appear slow due to the video and FPS.  The rpm was at the tool's maximum.

Would be a better, and more precisely for some part if round bar is moving between 4 bearing ? For example I make two of those U made during this video and put second on other side of bar, then U get bar surrounded with one bearing at every 90 degree ? ? I hope U understand me ? :) Cheers

[anajonesr]

@milek021 Yes, I did this initially, but the bar needs to be hardened steel to minimize the flex that will occur. I selected aluminum angle since it can be made to hug another supporting material and is much more rigid.

@pleabargain Thanks

[anajonesr]

@pleabargain Back then, that's all the wife would let me have. I needed to improvise with a vice grip.

Why is there a baby in the background?

[anajonesr]

@jmgully12 I have kids.

[jmgully12]

@anajonesr haha kk it was just funny to hear you talking about this and then hear a baby noise loll

[anajonesr]

@jmgully12 Thanks. It sometimes got on my nerves, but overall, the users seem to think it's funny, so I relaxed about it. You may even find them running around in some videos, but I do try to minimize the interruptions as much as possible.

hi. how thick is the aluminium block? I can buy 2mm and 3mm only. 

[anajonesr]

@chupascz The aluminum comes in the form of an angle and is 1/8" thick.  3mm should be fine, but 2 mm will be a bit too small.

[chupascz]

@anajonesr thank you.

[chupascz]

@anajonesr thank you

[rjarcher]

Thank you for posting this video. Ive just ordered a book on building a cnc router. I'm in the same position as one of the other commenters i have a small business but can't afford to buy a cnc router.

[anajonesr]

@rjarcher Thanks for the kind words. Let me know if you have any questions throughout the build.

[atomspace]

Thank you SO much for making these vids and for your website. I have a small business and we want to make some small signs out of pvc but can't afford to purchase a cnc router. This is a great alternative.

[anajonesr]

You're very welcome.

A bit of creative video editing to speed things up would be good.

[anajonesr]

Thanks peterwilson69 for the comment. I will do some editing to all of my videos to improve the experience.
