A:
Equipment: Mini lathe, medium size drill press (for most pen brass tubes are over 12mm)
Tools: safety shield, mask, earmuff, turning chisels, pen turning mandrel, press tool, pen blank drill vise, verneer caliper, long nose plier, punches, etc.
Material: pen blanks, CA glue, abrasives, polishing sticks, carnauba wax stick.
Bushing: except for the 7mm pen/pencils, you may need extra bushing for different pens.
Drill bits: please choose as recommended 

It takes time to reach precisioin and success.  We recommend you to start from 7mm slimline pen/pencils due to following reasons:

1. Most pen kits are hard to remove parts from barrels.  Please cehck and simulate assembly before you Really put parts together.
2. The larger tubes will create thinner barrel walls.  Please choose and check pen blanks carefully if any crack, or the barrel will get broken while pressing parts.
3. You may sand the parts a little bit down to prevent breaking.  If the part is too loose please put a little bit CA glue on the joint area.  In any case please keep finishing area nice and clean.  You should press parts very straight, if not, the side pressure will crack barrels.
4. Turn the barrel down to about 0.3mm larger than the bushing diameter.  Sand the barrel diameter down to bushing in 600 - 1000 grit, and polish by stick and carnauba wax.
5. Bushing will be worn out during sanding work.  Please change it periodically or barrels will be too thin.
6. Sharp turning chisel and correct curring angle are important to keep barrels from breaking.  
7. Suitalbe barrel diameter will keep pen clip in good shape.  If your barrel is oversized, you may break pen clips.
8. Keep pen blanks in true round or square.  No matter cutting by machine or hand saw, you may fine it hard to cut precisely 90 degree.  Cut it 0.2mm longer than brass tube and shave down to squre by trimmer.   
9. Do not change the tube length, or the refill will extent too much after assembling.
10. Choose low-odor and non-fog CA glue.  Make sure to work in dry place.
11. Pen craft requires higher precision in turning work.  We suggest you to choose a good quality mini lathe with true center.  A poor quality lathe will produce off-center barrels, which means different thickness outside the tubes.

Before you can really master pen turning craft, we recommend you to turn at least 100 pen kits of different kind.  We are not obligated and do not refund for ill-made finished pens.
