Papermaking PAPERMACHINE – DRYING Introduction

"web" at the dry end of a paper machine is only half that at the wet end. Thus, the "falling rate" stage is due in part to diminished heat transfer. This occurs because water evaporation away from the hot surface creates a layer of dry paper in contact with the roll. Dry paper is a …

Introduction: Types of Cylinder Head Port/Seat Design

from carpenterracing Cylinder head ports fall into two basic designs: the Straight Shot port and the High Approach port. In a Straight Shot port, the design allows for a line of sight from the inlet directly to the front opening of the intake valve. Sometimes this design gives a lower flow value but because it is straight, we attain higher velocity of fuel/air entering chamber.

Sharpening Chisels

Always start out a new -- or, dare I say it, an abused -- chisel with a hollow grind on a benchtop grinder, as shown (photo). I use 36- and 60-grit wheels because I want to shape the steel quickly and avoid heating up the tools. Overheating, usually indicated by a blue hue of the steel, causes the cutting edge to dull more quickly.
