I could not understand why the domed boiler end would not fit into the cylindrical boiler shell. After all, I had carefully measured the required diameters, and precisely made the wooden form, and I used a heavier hammer to finish the bending the flange. But the bent over flange still remained too big to fit into the cylinder by about 1mm.
A phone call to my expert friend Stuart provided the answer. Of course! When you make a 7″ disk fit into a 6″ space (roughly speaking), the material has to go somewhere. The material thickens up!
So back to the lathe.
AND ON A DIFFERENT SUBJECT…..
Reader Tim sent me some photos of this lathe which he has aquired. Looks like a quality machine. And I look forward to seeing it after restoration.
