![]() 230 forum posts 44 photos | I make a lot of small screws and have always turned the silver steel to size using a graver, not sure if I can turn steel down to small enough size using the compound but I will give it a go just in case I have been busy making a mounting so I can use the graver on my Myford, still got a couple of handles to make and do something about the horrible screw but I needed to be able to mount the tool rest to be able to make the handles but nearly there now , I will make the handles tomorrow using the graver, I know there's a device to be able to make handles but I haven't got one and anyway I enjoy using the graver. |

I make a lot of small screws and have always turned the silver steel to size using a graver, not sure if I can turn steel down to small enough size using the compound but I will give it a go The graver rest looks great, nice work! I have successfully turned screws as small as BA12 (1.3mm?) on a Super 7, but it took quite a bit of practice and scrapped parts to get the feel for it, as well as grinding a HSS tool with an almost dead sharp nose radius and lots of rake to minimise cutting forces (a tangential tool would do a good job actually). I would think that as you're already proficient with the graver it will be faster to stick with that technique, even though it is possible to use the compound/carriage feeds to do it. |

That was my thinking hence getting the tool rest sorted, I do have the tangential tool so I will give it a go but I think it will take longer to do it using the lathe than it would with the graver.

125 forum posts 14 photos | Looks good! Can i ask if you made the tool rest part? or alternatively is there a supplier? Did have a brief play with graving~ just resting the tools on a blank tool bit jutting out the toolpost. Impressed me enough to want to return to graving more 'properly' at some point. |

Hi Samual no I didn’t make the rest and I don’t know if they are available, the ones for wood turning are to big but I do happen to have another one spare but slightly different, pm me if interested. Dell PS I decided to just add straight handles because I had a couple more clocks turn up yesterday so I need to get to the backlog. |
