Update on the mill and lathe

Having used the mill a bit more, I have made a couple of adjustments and completed some bits I had planned for the lathe.

Guards

On both the mill and the lathe I've added some simple clear guards to replace the cumbersome factory supplied ones.


These are magnetic, so I can easily move them about to suit where I'm working. To me, it nearly always feels like guards that come with machines have been designed by someone who has never worked at a machine that is even close to the one the guards are fitted to.



Obviously I don't want chips heading towards my face, but I wear glasses or a face shield, so the guard is not the primary protection in that area. I find that more hot chips hit my hands, which are by necessity closer to the machine and largely unprotected. Most commonly, this is while using the handwheels. My solutions sort that out.


R8 Spindle

Since I've had the WM18 mill, I have been disappointed with the poor engagement of the keyway in my R8 tools. Never having used this before, I did not know what to expect, but I decided it should be better. The collet chuck would engage but not very positively, the Jacobs chuck arbour would fit at any angle!


Over the weekend, I decided to take some time to check that there was not a fault. It did not take me very long to find the issue.



I now know that the key is a simple grub screw and it was nearly all the way out the wrong side! I added a little medium strength thread lock and put it back in, to a depth that felt right. It now works as I imagined it should.
