I finally got my cutter out for the first time, and a couple of the cutters don't slide out. Or they did, when i got kind of vigorous with it, but now they won't go back in. Plus the top and bottom didn't separate, so I couldn't hold the metal in there very well. Luckily my husband is learning machining so I sent the cutter to school with him, and I am sharing this video with him too so he can see what I want. Thanks again!
Clever Kim You might have damaged the cutter when you labored to get the pieces out of the holes. If there are nicks in the holes, they can prevent the cutters from sliding through the holes. Your husband will undoubtedly be able to fix it. To avoid such problems in the future, be sure to keep the tool lubricated. And, if you have a hydraulic press, you can use the disc cutter in the press to ensure that the cutters go straight through the holes of the tool. Good luck. And, thanks for watching! : )
Hi Professor. OMG I was doing this soooo wrong! I didn’t realize the two pieces come apart and I was dragging the sheet metal in and out of the slide and cutting my fingers OMG THANK YOU as always for your wonderful tutorials, you are the best.
Glad to help. Thanks for watching the video! 😃
Hi, this was a helpful video, thanks. I just bought a 21 disc cutter with convex, concave and round tools, obviously the round tools are the cutters like the ones used in this video, but what of the convex and concave tools? do you have a video explaining how to best use those? I've done some searching around but can't find any.
Can you help?
Hi Fran, Without seeing the tools I can't be sure what they are. They sound like they are some kind of forming tool. Have you tried to contact the vendor for information? Sorry I can't be of more help.
Thanks for your support! : )
Hi John, thank you for your helpful viedo again, I am using pepe tools round disc cutters. Do you have any idea can avoid concave disc, I mean get a more flat disc. I am cutting 20 gauge sheet metal. very easy to get a concave disc. Thank you very much.
Hi keke shen, In my experience, there is always a bit of rounding on the edges of the discs. I typically will anneal the discs and flatten them on my anvil with a dead blow mallet to flatten them. Adding this step does create a bit more work. But, at least you don't have to saw out a "perfect" circle and improve it with a file. Good luck with your creative pursuits.
Thanks for your support! : )
@@OnlineJewelryAcademy Thank you so much!! john, It helps.
I watched a video where a woman put bur oil lightly on each cutter when she was using them..this she applied with an artist paint brush, again very lightly..do you do this ? And what a great idea to place over a roll of tape ! Thank you.
Hi Deby, No, I never lubricate the disc cutter when I use it to cut. It won't hurt the device to lubricate it and it will prevent it from rusting. I use lubrication when I drill. But I don't bother lubricating the disc cutter when I use it.
Thanks for your support! : )
Thank you so much
Would that work for Sterling Silver 1mm Sheets? Thank you.
According the a gauge thickness chart like the one found at this link: www.fastenermart.com/files/sheet-metal-gauge-thickness.pdf
you are working with 18 gauge sheet metal. Most disc cutting tools can handle this thickness. By the way, you might want to take a look at this video as well: www.onlinejewelryacademy.com/disc-cutter-demo-video.html
Thanks for watching! 😀
hi, can i use bees wax or vegtable oil as cutting lube?
Bees wax is an excellent choice. 😀
hi! Is it best to anneal the metal before punching??
It is better not to anneal your sheet metal prior to cutting discs. I hope that this information helps you to achieve your creative goals with confidence.
Thanks for your support! : )
@@OnlineJewelryAcademy Thank You! :)
I have designed a disc cutter for a specific application to cut 1mm 1008 grade steel, but it's not working out, it is just kneading the sheet...for that thickness and material, does the punch and dye needs to be larger and thicker than normal? thank you
First, I want to tell you that I have never used a disc cutter to cut steel. I've only used one to cut metals such as gold, silver, brass, and copper. Generally, the thickest gauge of sheet metal that you can cut with a disc cutter is 18 gauge (1.02mm). You're probably having trouble cutting the steel because it's as hard as the cutting tool. I'm sure it's possible to cut steel disc. You probably just need a lot more power to get the punch to go through the metal. If you don't need more than one or two, you could use your jewelers saw to cut them out. Otherwise, I think you should speak to someone who operates an industrial metal shop. Good luck with your project.
Thanks for your support! : )
Thank you very much for the info! I was able to cut steel only after I made a aprox. 70° angle cut in the punch and then tempering it...however, it is still kneading a little and loosing the cut easily, maybe I will have to make another punch with a harder metal. Thanks again for the help and your content!
1mm mild steel is beyond the capabilities of this type of punch. For steel punch designs take a look at what they are using in iron workers. You might get away with using a hammer with 1mm mild steel and this style of punch but a hydraulic press will work best.
3 mm cutting possible please reply me
Most disc cutters are capable of cutting an 1/8th inch (3.1mm) disc. And, you can always saw and file a 3mm disc. Good luck with your projects. 😀
Thank you for
Just a note of caution... using a steel hammer to hit the punches is not a good idea. Most disc cutters are made from heat treated steel and there is a very real danger of shattering the punch when hitting it with another piece of heat treated steel (the hammer). A brass or copper mallet is the best option. Alternatively you could place a piece of copper or brass between the hammer and punch. At the very least it will keep you from beating up your disc punch (or hammer if it's the softer steel)
Thanks for your excellent comment. We didn’t have a brass mallet in the studio when we filmed the video.
