Best Mini Lathe mod ever!! No more chatter!

Рет қаралды 28,855

Ай бұрын

This is arguably the best modification you can make to any 7x14 mini lathe to increase the depth-of-cut, decrease tool chatter and improve dimensional tolerances and improve surface finishes!.
Before this modification, I was turning a max D.O.C of 0.030", which is okay for this caliber of lathe, but it was not without chatter, galling and loads of other surface imperfections.
Another huge benefit from this mod is the ability to easily do parting operations, especially in difficult to part materials like steel and titanium. It's such an easy modification, I don't know why it took me so long to do it!
Accessing those two socket head cap screws to rotate the cross slide is as easy as loosening and rotating the QCTP to 45 degrees to expose the mounting holes.

Why didn't you just tighten the gib?

@Brute4rce1111 15 күн бұрын

The gib was really wonky on the top slide. It was undersized and had a bow, and would bind when moving the slide. On top of all that, You can see in the beginning video that it was missing a grub screw. It was completely stripped out. And lastly, whoever drilled the grub screw holes, drilled them too high up, causing the gib to roll down and create a lot more friction and wear. All of this created a rocky top slide with little rigidity, and lots of broken carbide tools :(

Yep, exactly! These little lathes definitely have potential if you accept their out-of-box faults and change them. On this lathe I have upgraded to Nachi tapered bearings, all steel headstock gears, and now this tool mount. Also, mounting the lathe bed to something substantial helps to increase rigidity 👍

Thank you for the video. I just couldn’t grasp how you adjust the angle on the slide. Do you have to remove the qctp to access the two screws holding the slide? Sorry, apprentice here.

If I loosen the qctp top screw, I can then rotate the tool post at an angle that will enable me to access those two screws. It's nice because I don't have to remove the whole tool post in order to rotate it :)

He can still mount the top of the compound. May have to mod it a little. Most of the time you do not use the compound feature. Actually many top machinist in have a solid tool post because it offers the most rigidity and change to the compound if they need to cut a taper.

With how loose that compound was initially, I think they forgot to put the gib in (or you loosened it way off for "illustration purposes" :) )

@Brute4rce1111 28 күн бұрын

It still had the gib in it, but I did loosen it to exaggerate the slop of it all 😄. I've had nothing but issues with it and it seems like a lot of other mini lathe owners have had similar issues too. On mine, one of the three gib adjustment screws was completely stripped out and the slide looked like it was slightly warped. This really exaggerated the slop it had. No matter how I adjusted the slide, it always felt either too tight or too loose.

Why do you loosen the gibs and then act like it is loose!!!

@Brute4rce1111 2 күн бұрын

@@mcgam2000 To exaggerate the slop for viewers. Ultimately, the slide was in bad shape and the gib would bind when I tried to adjust it properly. The gib holes were drilled too high, causing the gib to roll and bind up instead of closing the gap. I could still use it, but without adjustable fine feeding of the handle. I would just set the desired cut angle, cinch down the gib screws tight and start my cut. Definitely not an efficient way of turning!

@mervynprice7009 8 күн бұрын

Why is it that you people always take bigger cuts to prove that you have improved your lathe. The proof of improving your lathe is in the finish & ease of working. Deeper cuts just reduces the working life of your bearings & everything else by increasing the rate of wear. If you really want to improve your mini lathe, then you should have been adding to the number of gib screws. Adding stops to prevent the cross slide from moving whilst you are tacking an end cut & to the cross slide to prevent side movement during longer cuts.

@Brute4rce1111 8 күн бұрын

It's to show that overall rigidity has been improved. I no longer have chatter on heavier cuts, thus saving expensive carbide that would have chipped. It also speeds up my workflow if I have to turn down a part since I can "hog" out more material in a shorter timeframe. Regarding the spindle bearing wear, it's no problem because I have upgraded the headstock with large tapered roller bearings that have a dynamic load of over 9000 lbs.
