Viewports |

Here is the obligatory before and after shot. A lump of raw viewport material and the first three completed ports. After discussion with people at psubs, I put the first two back on the lathe and skimmed off another 1mm from the inside diameter of the bore. This will allow a clearance of 1.5mm between the lens and the frame. I have another one almost complete. I’m adding two extra ports to the design, so I have eight to do in total, plus the hatch port which is different. I also used a tungsten carbide changeable boring tip on the third one and it was much better than a normal one. I was able to put the speed up to 260 RPM which speeded things up. |
