Ok...rather than start in my usual way of explaining what I'm making and how I'm going to go about it, lets just start with today's positive.... MY FIRST SUCCESSFUL CLOCK WHEEL! ...after years of failures Chuffed to bits!!! Hopefully this will go in Parslows clock which I purchased the plans for back in November. I have all materials...just a case of working at it. More to be posted soon I hope. Chris |

Next, an attempt at pinions! I used some 8mm silver steel, turned it down to 5.69mm OD. I put the full cut on of 1.49mm and at low speeds of about 120rpm, started cutting with lots and lots of oil and a slow feed. The steel was not supported by a tail stock and so under the microscope, you can see slight vibration marks. A lot of hard work in polishing these pinions has started to bring any marks out the pinions nice and clean. The end has been centre punched a touch too far, so I'll need to turn a couple of mm off the end before I drill and ream then part each pinion to size. I've turned up 1" of pinion so have enough to make quite a few of the 8teeth that are called for however will need to make another lot up. It would be nice to try a tail stock but a. I don't have one for my 4" vertex and b. the tail stock and centre would get in the way of the cutter without some thought, Anyway, the fruits of this evenings labour. |
