Hi,
I`m sorry for the questions, I`ve got a few things going at the same time - all based on the same engine/build.
I`ve cut a few gears now for clocks (wheels) and my last attempt with Stew was succesful. I will continue with this method of wheel cutting when I resume my clock build...when that may be! However, I`m now after cutting a spur gear and I`m really happy now, after much headache, about how I will cut the gear. I`m going to use the calculations in John Stevensons article to make my cutter to get the correct profile. I`m actually all ready to go, I`m just not absolutely clear about how to make the cutter profiling tool.
I can see all the measurements, I`m just not clear how to mount the buttons. Again, I can see from John`s article it is using grub screws but I think a picture would be helpful just to clarify! Is the distance between buttons adjustable or does the bore for the buttons just have to be cut accurately so that they are the correct distance apart.
Does anyone have a picture of a gear cutter profiling tool? Just to be clear, I`m not asking for the gear cutter itself or even the profile of the cutter, I`m just confused about the tool for holding the pins/buttons to offer upto the gear cutter blank.
