Hi
I have been working though this. Here are a series of drills I'd done with the machine out of the box. Either a flat relief or going the wrong way

I ground a pointer and installed it in the drill holder and offered the point to the grinding wheel

As I had suspected putting it into the setup jig the there was a gap between the end of the pointer and the touch plate in the jig.

Looking at it the other way round if a drill bit was set against the touch plate the extra material would need to be ground off before the grinding ceased. This would then mean that the cutting lips would be ground beyond the intended location on the flutes.
This should be easily resolved as the grinding wheel can be moved along the motor shaft. However, on my unit flat on the shaft, that the grub screw bears on doesn't allow the grinding wheel to be moved far enough. That is, after the pointer has been set to the correct length on the setup jig, the tip of the pointer should be just rubbing on the grinding surface.

I have tried with the grub screw being clamped directly on the motor shaft and not the flat and using the machine like this I get perfect results with drills from 3mm to 12mm.
I now need to work out how to get the split point to work. I think there will need to be a compromise between the position of the grinding wheel for the basic grind and the split point.
So when doing split point on the Sealey do you reset the drill bit in the jig after doing the basic grind? The Chinglish instructions that came with my clone don't advise to do it but some YouTube videos say you do.
