Product Vevor BS-0 Dividing Head - review ish…

[Brent H]

So I purchased a Vevor BS-0 or 1 to help making gears and such as my 12” dividing head is very heavy with an 8” chuck. Mailed from BC it arrived today - impressive 5 days across Canada BC to NB

Box opening and there are 2 loose screws - they seem to fit nothing other than possibly the dividing plates? Here is the box markers:

So the dividing plates were all right and range from 31 to 49 holes (have to confirm) and you get 3 with 6 lines of holes. I had to clear swarf out of 2 of them but they look fine

The index plunger was stiff and needed some tuning up - might need a better spring (like a bit more load pressure). The pressure clip that holds the clock arms in place was too big for the application and I had to grind off about 3/32 to 1/8 off the outer edge to get a solid fit and no interference with the clock arms. I changed out the allen screw holding the plunger with a set screw and changed the stupid Phillips head lock screw with a allen head cap screw.

Size difference is huge which will help my back as well as allow full use of the mill height.

It dialled out at 0.001” run out and I will be checking things out further. It has some backlash (0.020 ish) so it is important to keep your turning direction consistent. I will have more to say as Input this unit into fabrication

I debated hard on H/V rotary table or dividing head. Looks like a decent unit Brent.

I have the same model from Vevor as well (bought feb 2024). While I wouldn't describe it as a fine piece of engineering, or machining. I would describe it as adequate for the money. The one I got anyway, there are mixed reviews on them as with all things MIC, so I would give yours a really good going over before your return window is closed. I've had mine all apart to clean and deburr. Fit and finish is on par with what you'd expect for a $372 delivered dividing head from mainland China (expect to file burrs off everything), but dimensionally I didn't find any huge issues. Runout was under a thou on all the rotating surfaces (I think a pin in the chuck was slightly over though, I can't remember), and it was pretty square as well. I did not check it all through it's rotational envelope, but square at rest was pretty good, and the trunnion fit was tight and not sloppy. I didn't blue it, I didn't really want to know that bad lol. Tight was right......The pin to plate fit is very sloppy though, and the sector arms are what I would call complete trash, but they would still do the job they need to so. But it's one of those things that leaves an impression. Put time and effort into the fit and finish on the things that your hands touch the most. In this case, I think they did the opposite.

So far I've only used it once, and it worked great. Although that was only a make work job drilling cross holes in a pin I could have done in a collet block. I have a couple model engines I'd to build at some point, and they will need gears, so that was the reason I bought it. If I ever get through some other projects and get to them that is.....I will probably at some point want to make a new pin and sector arms though, whether I actaully get around to doing it is another story......

I'm on the fence about buying one of their 8" rotary tables too. I've been trying to find a reasonably price used one and so far have not found any used ones (10-12") worth buying, and have missed out on the ones that were. The 8" is a bit small, but would fit the job I have a need for one on right now. A 10" would be perfect, but if I could find a 12" like your STM I'd take it too.

@Dan Dubeau - I would agree with your points on the unit. I will see how it does on some heavier cuts. The screws that should fit that dead centre mounting thing are too small so I will have to fit some 6m x1 screws. I may have more to report after I play with it more.

Ok, so some things got better. After removing the indexing plate there is the ability to engage or disengage the worm drive. This allows you to remove all the backlash as well as run the head with a gearing system (if you wanted).

As I mentioned earlier I ground back the edges of the clip that retains the hands.

I removed the 3 jaw and the threads were quite crap at the inside edges. Just needed the paper thin material filed out.

You can see the wavy washer effect. That filed out fine and all things thread on fine. Looking forward to its next project.
