Hi Guys,
Following the drawing in the previous post, here are pictures of the finished items.

First the two screws used to support the aluminium sleeves. I've knurled these with a fine diamond pattern knurl. A little easier on the fingers that a course one.

And a picture of one installed on the "X" slide dial.
Thanks for looking Guys.

1st attemp at a slot drill !
Hi Guys,
I've just been having a try at grinding one of the two slot drills that I cut the damaged ends off ! I've shown it in the first picture. I've simply used a Dremal and cutting disc to remove the broken end. The cutter is now about 8 mm shorter than it was.

Whilst the finger did allow me to initially set the grinding angle using the cutter flutes, I found that it was very difficult to re-establish the same position in order to make a second grinding to take another cut. The finger simply wasn't rigid enough. In addition it caught on the side of the wheel forcing it out of position. Not good for getting the flutes equal lengths.

Previously I had made this collar that fitted on the tail end of the collet holder shaft in order to micro adjust the amount of cut. In practice I found that the zero backlash on the "Y" slide was quite able to make fine enough adjustments of cut, so I pressed it into service as an index ring by drilling four holes at 90 degrees to each other.
The next step is to make a peg that will fit into the holes and give me a positive step for two or four flute cutters. I also intend to replace the thumb screw with a Allen hex grub screw so that the collar can be locked onto the collet shaft.
I'll post pictures of the modifications as I do them, so at this moment in time any helpful suggestions appreciated.
Thanks for looking !
