Should you really get the biggest lathe possible?

Jason- Inside and outside, last job I can remember ( 40 yrs ago ?) it was the mould for large plastic sphere halves , about 1 mter dia. with a center piece.leaving about 10mm gap. Invoved inside and outside spherical, flanges and bolt pitching. All to a very good finish and by hand, ie. no CNC. These sort of machines were common in my youth. Unless I.ve been dreaming, wouldn't be surprised!

Hi Roger

My DSG doesn't have the auto trip but I do like your arrangement. That's another thing on the to do list

Many thanks.

David.

In the photo above,the blue machine,it is known as a vertical borer,or vertical boring mill, or in some countries a vertical lathe. the big advantage is the job can be loaded onto the rotating table far more easily than securing it to the faceplate of a large lathe,also it can be set central without struggling with clamps at the same time ,set it central first then clamp it down, also the borers can be built far larger than a lathe, modern vertical borers as per photo are set into the ground so the table is level with the ground ,easier to work on and set up,a lot of that machine is below ground on a very expensive concrete pit.
