Hi everybody, a Very Merry Xmas and a Happy New Year.
I have made a furnace, and want to turn a ramp or helix for its swinging lid. This is in order to make it lift up as it swings to the side. The lid will be in the way of the crucible of molten metal if it opens conventionally with an upwards movement. I realise that I could fairly easily fabricate a ramp, but you see, I've got new servo motors on my lathe, and I'm sure it is capable of machining a ramp onto a bit of round bar.
All I need to get me started are some ideas about how to do it. I haven't been able to find a ramp wizard.

You just might be able to cut a short thread and use that.

Thanks for that idea, I hadn't thought of that method. A short thread with a coarse pitch and a large depth might work. I'll do some experiments and let you know.
Cheers
Dave
