VEVOR Gem Faceting Machine Product Review

[@CarlDi3trich]

Just an update on two issues that I licked without resorting to a fabricator. Issue number one is the 90 degree angle. Once you remove the brass fine tuning cuff on the mast the manipulator sits about 15 degrees below the table. This can be fixed with simple steel washers. I'm using washers with a 15mm inner diameter which fits the mast perfectly. The washers are 2.5mm thick so it takes about 4-5 of them to get above the table. Add more as needed for the size of your stone. Issue number two is getting the pen to move freely when making a girdle. All this requires is removing the steel bit that fits into the tooth wheel. Just be careful to keep all the pieces together for when you want to use the wheel.

I love how you did all your work arounds! So if you get the pieces you need to facet, are you willing to give that a go too? Im glad you got it at a good enough price to use it as a flatlap. Thats awesome. As long as its working for you! Nice work station! Thanks for sharing!

Hello @offyarocka I recently got this same machine, i love your video and it is helping me set it up properly. however, the digital display does not turn on, and i am not sure how to provide energy to it, is it battery operated? if so, how do i open it to put batteries in? i appreciate your help.

[@offyarocka]

Hi Omar, thank you for the kind words. Yes the digital display takes a watch battery that goes in at the top. You will need a set of needle nose plyers to pull the battery holder out. ✌🤠✌

Apparently there is also and issue with being able to cut a girdle with that mast which is a bit disappointing. But it goes ok as a flatlap ✌️✌️✌️

Hey could you please explain more about not being able to make 90 degree cuts on this machine?

[@pigeonbloodruby5330]

A couple ideas to stop the thread from working it's way out. If there is room add a thin jam nut. Removable Loctite. Form a perfect fit, break it loose and maybe there's enough friction to keep it in place. Take a hammer and flatten the to outside diameter. Or use a pair of vice grips to crush the O.D. Leave the threaded bolt inside to prevent over crushing. Force the threads to have a slight interference fit. Tks!

[@offyarocka]

Thanks for sharing those ideas, I am a big fan of loctite, used to use it alot when i worked as an engineer. The system im using now is really good, the spray bottle holds 5lts vs 300mls of the canand the irrigation tap is really good for getting the water levels just right. I got the idea from a bead maker that Lapidary Dave put me onto, www.youtube.com/@lopackistoneandmetal3955

@@offyarocka OK, you upgraded the water system better than the original! I like his use of the hand pump sprayer, very nice! What type of engineer are you? I've watched some of Daniel Lopacki videos before. Specifically the home made flat lap. I would love to try hand polishing some 'pearly' shaped gem fire agate like the ones Daniel has (~10 carats). I don't care much for the brownish ones, but I'll practice on the inexpensive ones. Do you know anyone with some still in the rough? Daniel also mentioned the location that he thought they were from. But I couldn't understand what he said. Do you recognize where they came from? kzbin.info/www/bejne/qV69pmRuhMmAna8 Thanks for the tip!

[@CarlDi3trich]

The manipulator arm is useless out of the box. It requires a fabricator to fix if you can find one that will work on it. The machine is only really useful as a flat lap like the Diamond-Tech. For all those asking there aren't any replacement arms that work with the machine. You will need to save up for a better system or have a friend with a lot of machining tools if you want to facet.

[@offyarocka]

Yep that is the guts of the review right there. Did you get any kind of refund or discount on yours?

[@CarlDi3trich]

@@offyarocka They just offered to replace it. Not sure what "it" is. The whole machine? The mast assembly? Dunno...but I said "If it fixes the 90 degree issue then sure!"

[@CarlDi3trich]

@@offyarocka So they sent me a whole brand new machine. No charge. But it's exactly the same as the old machine. So I sent support a mail outlining that the issue isn't that the machine is broken. The issue is that it's built wrong. I also sent them pictures and recommendations on how they could have manufacturing fix this issue simply ( raise the table by 2.5 inches ).

[@togetheragainrecords]

I bought one of these brand new while living in China (where it is manufactured) Great for a flat lap only I had the manual mast (no digital dial) that had the protractor measurement settings It has a lot of “play” and is difficult to set the exact angle as the pointer is not fine pointed enough to measure correctly Yes I cannot cut 90 degree girdles either (without modification of the machine) This is very disappointing and I feel like I wasted my money on this machine I would recommend not to buy this machine if you want to learn facet cutting sapphire/diamond Only buy for use as a flat lap (Wish I never bought it, currently looking for an upgrade) Great video Than you for sharing

[@offyarocka]

Thanks for stopping by and checking out this video. Another way you can get into faceting is through your local gem and mineral society club

[@stephenslater3312]

Dont waste your money. Its fine for cabochons, but useless for facetting. the bearings on the swing bit are to loose, and no way to set and keep an angle.

[@offyarocka]

that was my biggest issue with the mast was not being able to lock in the angle. Thanks for stopping by

[@stephenslater3312]

@@offyarocka My brother made me a lock so that was fine, but when trying to zero angle it was not consistent. We even made a v block to put quill in and zero, but the moment you moved to cutting angle and back zero would be off by up to 3 degrees.

[@offyarocka]

@@stephenslater3312 that would be so frustrating.I wonder if getting a better mast might help, like a non vevor one?

[@stephenslater3312]

@@offyarocka Possibly, but another problem is getting the girdle round, you cant move the mast back far enough to get at 90 deg. Different mast might be ok if there are some s/hand or broken machines about that are cheap enough. I gave up and saved up got a V5 arriving next year.

[@DonariaRegia]

@@stephenslater3312 You can stack two master laps to bring the lap height up for girdles. The main problems with these particular assemblies is wearing surfaces, tolerances, and micro-adjustment. Even if there is no play out of the box with use there will be due to metal against metal wear. The worst place to experience wear is the index lever, no angles are repeatable and step cuts won't be aligned. The quill is not removable, making proper inspection of the stone difficult during all stages. The front quill bushing will wear quickly due to rotation and from both the sweeping motion and pressure applied during use. The wearing surfaces on the mast sleeve will also lose tolerance. A handy person can bore each component and press in bearings, but without a protractor assembly this particular machine won't be of much use except for cutting cabochon girdles.

[@alanmillward64]

Totally useless for faceting. You can't cut a girdle at 90degrees. There isn't enough room. The one I purchased seized the bearings the fouth time i used it and there was a lot of rust.

[@offyarocka]

I agree totally, i was a little dissapointed i couldnt facet stones with this. That sucks about the bearing going to have a look at mine to make sure that doenst happen to me.

[@aeonsmiffy]

Has vevor responded to the fact, this machine is useless for faceting? I’m about to purchase one but won’t if it’s not any use. Any advice, appreciated.

[@offyarocka]

@@aeonsmiffy I did contact them about the fact you can not facet with this machine and because I baught it from ebay and not their online store the were less than helpful. i even tried to get the part needed to lock in the angle on the mast from them and the were actually pretty rude and would not help. The response I've gotten from the Facebook groups I posted this video in from other people who have baught one has been the same, its an ok flatlap if you get it for half price but rubbish for faceting. I hope this has helped . Im planning on making another video were I use it as a flatlap in the future.

Like a lot of cheaper products............it looks like the real deal but is garbage. Some items are ok, others not which is why these reviews are good. Let someone else try it first lol.

As far as this facetor.....I suppose if you were a machinist, tool and die maker etc you could probably do something with it but ill pass.

It has turned out to be an good flatlap. I have cut quite a few rocks on it and the have turned out great. I've been looking at those vevor smelters too, i'd love to try out some casting.
