A bit of creative video editing to speed things up would be good.
Thanks peterwilson69 for the comment. I will do some editing to all of my videos to improve the experience.
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.
You’re very welcome.
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.
Thanks for the kind words. Let me know if you have any questions throughout the build.
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.
Why is there a baby in the background?
I have kids.
haha kk it was just funny to hear you talking about this and then hear a baby noise loll
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.
Back then, that’s all the wife would let me have. I needed to improvise with a vice grip.
Thanks
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
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.
RPM on the drill is way too slow
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.

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.
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.
Dude, I fucking love you.
