As you ca see I have machined them all at 90 degrees to where they should be :-( This was very disappointing I did take them down to my local model engineering club so everyone could have a laugh at my expense, luckily they were a bit more supportive than that. After several weeks of being glum, one of the members suggested cutting the covers off with a slitting saw. So I did! There was just enough meat on the slitting saw to remove the covers in one cut. This slitting saw is rigid enough not to be deflected during the cut. Plenty of swarf generated but I had lots of material to play with. Due to the low cutting speeds the cover did not fly off to the far corner of the workshop. As you can see there is a small curl of material still attached I had to file this off in the vice usin...
