MANDRELS:
A mandrel is a round steel rod that you slide the wood blank with the brass tube inserted onto. Unlike most other companies who offer only one size mandrel we sell two sizes. The A mandrel (sometimes called a "7mm" mandrel) which is 0.247 +0 -0.002 inches in diameter and and other mandrel which has a larger diameter, the B mandrel. This is 0.291 +0 -0.002 inches in diameter. We use the B mandrel on some kits because the thicker diameter helps prevent whip while turning and allows for a much better result.
BUSHINGS:
These are round pieces of steel that slide on the mandrel between the mounted pen blanks. You must turn the wood down to the top of theses bushing to achieve the correct wood size. Each kits has specific bushing. The letter after the bushing number indicates which mandrel to use the bushing on e.g. A or B.
DRILLS:
We sell unique precision industrial drills called parabolic flute drills. These cut faster, more precisely, and last up to 10 times longer than ordinary drills. These drill wood, plastics and Dymondwood effortlessly.
