Having tried "stealing" the dome from a door knob - well it seemed like a good idea at the time
, I ended up buying a radius turning tool for my C3 lathe.These are the parts as they arrived:
They're covered in red grease so need cleaning before use - don't use Methalated Spirits - it attacks the red paint
Fitting to the lathe requires the removal of the compound slide:
Once the turning process is finished the bar looks like this:
My lathe needs a little TLC, so the end finish isn't the best but it cleaned up well with a little emery cloth.
Sharp eyed viewers will see I had to "engineer" a solution to hold the part, having cut the bar too short for the tool - I had forgotten how far the bar needs to extend so that the tool doesn't interfere with the chuck
Parted off and cleaned up, the finished dome is thus:
Next job is to cut out and shape the backing plate.
