855. Learn How to Control Chattering on a Noodle Bowl with Hsin-Chuen Lin 林新春 示範如何控制跳刀

So, in case you are wondering what did I use for getting my bowl to stick it onto my bat, it's very simple. It's just water. Um, after I brush the water, I can just put it on here. And once the water dry or one water contact with that the ball contact with the bat you will create a slip in between and the slip is using the slip as a glue to glue them together. So if you want to use water or slip method to get your piece stick onto your back the best way is to learn how to tap sandering because once you have a water in between so that's how I stick my piece on. Um, now my ball is sticking on the bed very firm without moving. Otherwise, you could use just the clay coil to stick them on. So, I'm using my D-shaped tons cover look to drum. Tons carbide tool is my preferred tool now because they don't wear out easily. They don't get dull easily. They stay sharp for a very long time. So once you are using the tons carvite tool, it's hard to get back to the normal material unless I'm doing a um chattering or unless I am um doing some special trimming. Otherwise, the tons carbide tool now is my favorite tool to use. And for the carbide tool, normally you want to trim your clay little bit on the firmer side cuz the tool is very sharp. So, it can go to the clay easily. If you trim it on the softer clay, you might get unwanted chattering. The unwanted challenge is caused by first you might spin your wheel too fast and secondly you might trim your clay too soft. uh especially on the groggy clay because when the tansai they are very structural and when you cut the gro and the soft clay and when it hits the gro the grub is harder so it's harder to go but once you move to the soft spot the soft clay is going to make a dent so you cut the grub and the soft clay gro and soft clay so it kind of create a vibration that's why if you keep on doing it, you will get the unwanted cherry, especially on the groy clay. So, what you want to do is slow down the speed of your wheel and uh try not to cut your clay too deep at a time and try to get a a angle that if you find out you start to get the unwanted chattering, try to use different part of a tool. Maybe just like using the corner. So you will have less resistance instead of using the whole blade. If you use the whole blade, you might create the unwanted char easily. And also when people are using the tool to cut it, they always hold the tool this way like the tool is on 90° to the surface of the clay. 90°. That way you are kind of like scraping scraping the clay like this is this is your blade and we holding the clay this way. See that that you're scraping so you get the chattering mark. So you might want to slightly tilt tilt your your blade slightly tilt so you are shaving it up instead of scraping it. Scraping it is easy to get. See that? You hear the sound right? That is chattering, right? Chattering. Okay, chattering. So, slightly tilt tilt your tool and spin the wheel slow little bit slower. Slightly tilt it. If you find the uh chin start to come in, tilt it. Maybe use different blade, different part of your blade to cut the clay. Maybe one portion of it instead of using the whole blade. Because you are using the whole blade, you might have more surface area touching the clay which you have a more resistance and easy to cause your tool to vibrate. Slightly detailed it and you are shaving the clay off. And also not try not to cut the uh thick clay. cut it too deep at a time unless you have a lot of to remove it. This tool is very sharp so it's very easy to get the ruler clear easily and also get your finger closer to your tool and maybe one other hand to brace it. Okay, the other hand I usually use my thumb to brace the the head of the trimming tool. and cut a smaller thinner ribbon off. Now you can see that I don't create any of uh the unwanted chatter mug. The silver stay smooth. But if you want to do the chattering intentionally, what I will do is just do the opposite. Like I don't put my other hand to brace it and I speed up the wheel faster and I hold my tool loosely faster. And I hold my tool loosely and longer. And you can see that my tool start to vibrate and it start to create the cheddar mark. See the cheddar mark? Because my tool is very sharp. So it's easy to get cheddar mark if you don't hold the tool firmly and uh closer to the head. Now I want to remove the uh the mark the cherry mark and sometimes it's very hard to remove the unwanted cheddar mark because it's you already have the uneven surface and you tend to go into the uneven uneven and exaggerated. So you to go slowly and then cut it slightly deeper. Like I said, you want to reduce the speed of the wheel to now here see this part here I already removed the cheddar mount you can compare here this is the cheddar mount this is on cheddar mount and let's do go down a little bit further There. Okay. Now we can see that I removed the that chatter mark. Okay. So this is the trim. I show you how to use uh how to avoid the unwanted chattering and uh also for on purpose chattering. If you want to do the cherry [Music]
