Check out our Wedding Thankyou
...And our new Baby Announcements
Born in Omak, WA "returned" to Goldendale to finish out my hundred
year plus, stint...
|Went to Washington State University|
|Worked @ Goldendale Aluminum 8 years|
|Got my Pilots license in 1993, Plane in 1994 Mooney
Profession - Senior Mechanical
Design anything that moves... that doesn't contain a whole lot of concrete
or too many electrical thingys.
- Powered Deck Trimmer
- Designing a machine to automatically trim(sweep) Soderburg Aluminum
Reduction Cells. Performs this hot, dirty work "Like a Video Game" from the cab
of a hydrostatic, air conditioned vehicle. Unit is equipped with proportional electric
hydraulic PID feedback control system which monitors brush motor torque and automatically
adjusts the height of the brush head to maintain consistent brushing action. Currently
using a PLC Direct PLC controller to improve
reliability and brush life.
- Custom Tapping Vehicle
- Designing a new self-contained tapping vehicle with on board air
compressor and Diesel engine. Existing units are battery powered and must be tethered to
air hoses. New tapping vehicle will be equipped to draw metal directly into a transfer
crucible, thereby eliminating an existing pour operation that transfers metal from tapping
to transfer crucible. Eliminating "the pour" cuts gaseous fluoride emission
dramatically, eliminates unsafe and floor damaging, molten metal spills. Not pouring
reduces metal reoxidation thereby contributing to project payback..
- Diesel Powered Mobile Crustbreaker
- Current section air crust breakers are tethered to a plant air line
resulting in limited range, and dependence on varying plant air pressure. This inability
to move around the plant requires numerous spares to distributed throughout the cell
production lines. The current prototype is mounted to a standard Hyster fork truck frame.
A modified hydraulic system with regenerative cylinder extension and accumulator energy
storage(during upstroke) are employed to afford greater breaking power while maintaining
the fast cycle time of the air powered units. Controls are integrated into a single
joystick equipped with a top mounted toggle switch.
- Spading Machine Overhaul and Hydraulic Upgrade
- Remove outdated, unresponsive hydraulic pilot, joystick controlled hydraulic control system and replace with modern, proportional electric piloted load sensing
hydraulic system. The
new system is a nine function hydraulic stack with internal load sense shuttle network and
proportional flow control spools providing finer control while eliminating about forty
hoses and six discrete valves. The system allows adjustable load sense pressures for
each direction of each hydraulic function. The flexibility of
electric control signals may allow the elimination of one of the three existing joysticks.
Two ergonomic, multifunctional joysticks should be able to perform the same
function with much less operator fatigue
