This would have been much more interesting, if you had done a precision test, right out of the package, so we had something that we could compare the end results with. And maybe sped up the cleaning, just a smidge. Otherwise a great video.
We did not get a run-out check as bought. How do I know cleaning and de-burring increased accuracy and decreased run-out ? It may have made them smoother and easier to open and close, but more accurate ? I doubt it.
It would have been good to do a pre maintenance check. My goal was to get as much precision as possible out of budget chucks, but good suggestion for next time!
Umm. You just disassembled, wiped grease, sprayed a WD-40. How does it make any difference to a precision? No accuracy tests before disassembly. So what do you tried to show?
@@ПетрИванов-ы6е in my experience, heavy grease like that catches and holds onto find bits of grime and grit over time, causing a buildup over time that can adversely affect the accuracy of the unit. I’m addition to properly lubricating them, I disassembled them in order to evaluate their internal machining and in doing so discovered that two of the chucks had poor internal machining while one had fantasfic internal machining. The WD-40 you referenced is actually a WD-40 branded white lithium grease spray, not your run-of-the-mill WD-40. It’s a fantastic light weight grease and doesn’t get clogged up with grit as badly as heavy grease does, while still providing excellent lubrication. That’s just my experience though, your mileage may vary. The link to that product is in the description. As depicted in the video, I also located and removed several prominent burrs. A burr is a small shard of metal that juts out along the edge of a machined surface, left over from the manufacturing process. These could also affect accuracy and operability. I do appreciate the suggestion to include a pre-maintenance data point for accuracy in the video and will incorporate that suggestion in future videos. Thanks for watching.
Although it was an interesting disassembly video, I was anticipating "...turning my cheap drill chuck into a precision tool...", with your video but was greatly let down. Again, not by the video. The video made for a great review and research video but the title was a let down.

Thanks, good feedback for next time.

Sorry to let you down, Eddie. I’ll fix that.
