Hi Lenna, I'm so glad that you enjoy my style of online teaching. I hope you've learned a ton from watching OJA videos. Thanks for your support! : )

Thanks for the video :) I would say that the polishing cones and the wheels made my life soooo much easier. Most of my work is actually carving fossils ivories (Mostly Mammoth ivory), antler and bone. I use the cones, wheels and I also have a kind of micro cone mandrel that holds 3mm wide polishing cones. We really appreciate your videos John, keep up the good work!

I just want to mention: Metal powders created by abrading them are extremely bad for your lungs (As you can see in the video, John has said he wore a dust mask during grinding and keeps the pieces well away from his face) and I want to remind people to wear a mask and or use a vacuum cleaner with a good filter in it and work in front of the suction head to avoid getting metal powders in your lungs. The small cut off wheels also have epoxy, fibreglass and abrasive grit in them.

Thank you so much for this video! I really need to get a flex shaft. I've been using Dremel rotary tool and it's excellent but I've been holding the whole tool in my hand which goes numb quite quickly while working. Flex shaft will give me much more freedom. There's also so many bits I haven't been using yet, so excited to try them!

Prof. John, I only have a Dremel but I have all the attachments. ..do I really need a flex shaft or can it wait until I havey cabin workshop up and running? Should be by summer when I will have it all kitted out for hot work and any heavy duty stuff. I'm managing with the Dremel so far and my torch but really want a proper kiln and forge and I am not the best at waiting (I know, its like instant gratification but I get all excited about projects and am a bit of a kid when I have to wait to try stuff out! lol!

I agree with John. For myself, I have a dremel, a foredom and a special dental micromotor machine (Kavo K10), but before I had all of that, I was using a 10 dollar clone of a Dremel (Without flex shaft, since it was badly made, the one I had) and it served me for 4 years :) If you are in no hurry, you can order a good flex shaft from Aliexpress for really cheap.

@Foxiepaws A - Wen makes a good rotary tool, the entire kit is only ~$20 - that’s for the tool, attachments, and a 4’ flex shaft. I have a brand name Dremel too, and the accessories are completely interchangeable. I’ve had no problems with either the Dremel or the Wen, but you can’t beat the Wen price: www.amazon.com/WEN-2305-Rotary-Tool-Shaft/dp/B003BYRFH8

What is the best attachment for super fine polishing. Very little scratching. Just hairline. It’s for my Rolex. I have very fine surface scratching. I need to bring back the shine. What can I use

@OnlineJewelryAcademy

I would recommend that you take your Rolex to a recognized Rolex dealer and have them send the watch in for refinishing. You don't want to do anything to an expensive watch that could potentially decrease its value or void its warranty. Thanks for your support! : )

Hi. Great video. What are other uses for the separating disc? Thanks!

@OnlineJewelryAcademy

2 жыл бұрын

As mentioned in the video, separating discs can be used to remove sprus from castings. You can also use them to grind surfaces flat for soldering. You might also use them to carve a decorative textured surface. Thanks for watching the video. 😀

It seems like hearing protection might be useful for some of these grinding and sanding tips.

Does any "washer" have to be on top, or are they ever underneath? And if so, or not, why? Thanks

The washer helps to keep the screw from slipping. It works best when it's on top in my opinion. Thanks for your support! : )

You can wear a mask during both procedures. However, if you use wet/dry sandpaper under water, no mask is necessary when you sand. 😀

Hi Kaye, Based on your description, I believe you are describing an item similar to the one in the photo for the video. Just be sure that you have screw in mandrel that are threaded in the correct direction. And, be sure that you are running your flex shaft in a forward motion. Otherwise, the element on the end of the mandrel will unscrew itself and fall off. I hope this helps. Thanks for your support! : )

@artisankatstudios7902

7 жыл бұрын

You should put it in a vice grip or a clamp (Making sure not to bend the shaft) and make sure the sanding piece is twisted all the way down. When you start to use it (Until it wears down to a cone shape top), just use light pressure. I had the same problem until I twisted it down well.

pendant motor or micro motor; why choose one over the other?

@OnlineJewelryAcademy

If you mean flex shaft vs. Dremel, I would choose the flex shaft because there are more accessories for it. This includes different types of hand pieces; including hammer hand pieces and quick change hand pieces. Thanks for your support! : P

There are many good presenters on various subjects on KZread, but your presentation clearly shows you are a great educator. Clear, concise and informative. But I am cringed when seeing you hold the parts by your fingers when cutting or polishing them. The parts or the flying wheel can fly off accidentally injuring you or the Dremel operator. The 30,000 RPM Dremel can cut off your finger in a blink of an eye. Why not laying down the coil on the table and holding the wooden rod while cutting the coil? I would use a pair of piers to hold the brass piece while shining it instead of holding it by your fingers?

Thanks for the compliment. I'm glad you're enjoying the OJA's videos. But, I'm not using a "Dremel" tool in the videos. The speed of the tool is not as great as you stated. Second, I did not demonstrate with any attachment that has the capacity to "cut off my finger in the blink of an eye." Thanks for your support! : )

difference between a "mizzy wheel" and the last white wheel you used, it's all a bit confusing....we need to know why we'd use one instead of the other, etc. (tough question, I know...). Please illuminate us with the REAL info, the whole "whatever you choose" thing is soooo misleading, mixed up. There just MUST be a reason to use one item over another... I hope! Thanks!

The mizzy wheel is a very course grinding wheel. The silicone white wheel is not quite as abrasive. If you look up the various attachments on a jewelry supply website in a supply catalog, you can read descriptions of their qualities and what they can be used for. But experimentation is really the best way to become acquainted with these tools. Dremel sells a set of attachments for their tool that includes many items similar to what was shown in the video. Thanks for your support! : )
