Through Hulls |
25/06/08 |
Here I’m starting to make the through hulls. I’ve cut, faced and turned this piece of 316L stainless to the right length. Then I centre drilled it and drilled it through to 8mm at 1120 RPM. Here I am about to drill it through again to 15.5mm at 470RPM. The hole will be reamed out to 16mm. |
