Last year I purchased a dowling jig. It is pretty good for 8mm and 9mm holes. But it has nothing to support small diameter drills.
I currently need to drill 3mm holes into a defined target. My attempts at dpoing so freehand have been unsuccessful.
What I need is a sleeve to fit inside either an 8 or 9mm drill guide tubes. I have tried plastic plugs (rawlplugs) and tried to find a suitable ballpoint pen case.
I need inspiration.
TIA,
Alan
