==Overview==
{{Sawmill}} Design

==Design==
'''Z Height Leveling'''
*Turnbuckle attached to upper z adjustment peg

'''Evenness of Z Height Raising Along 4 Posts'''
*Build 4 inch winch drum - each revolution winds 1' of wire

'''Log Taper Adjustment'''
*Disconnect mechanism for connecting rod between front and rear z-risers to create a height differential between the two ends of the log

'''Edger'''
*Adjustable from 1-3 blades in standard version, up to 6 for 6 2x2 lumbers in one pass
*In 3-blade configuration, top edger blade is controlled by a crank that can be adjusted while sawmill is running

'''Gantry'''
*Box truss design

'''Carriage''''
*Clearance of 1/8" around gantry

'''Hydraulic Hoses'''
*4 Hoses
*Mast at either end

'''Trailer Hitch'''
*Telescoping piece of tubing in frame
*Hitch retracts for sawmill operation

'''General'''
*Counterweight for hydraulic motor on one side of gantry - balancing
*Saw and collar - typically from same manufacturer

'''Vertical Motion'''
*One crank with a worm gear controls one side, connected to second side via connecting rod
*Vertical adjustment - 4 worm gear sets - [http://www.bostongear.com/products/open/index.html#]
*Bronze bushings - for vertical adjustments

'''Horizontal Motion - Crosswise'''
*Crank with indicator
*Sprocket with chain to another sprocket with pinion, riding on rack
*Rack faces down
*Sprocket and pinion sheltered from dust
*Connecting rod connects to other end
*Link rod contains a telescoping slip joint with pin, to retain of modularity of track lengths

'''Horizontal Motion - Lengthwise'''
*Festooned hydraulic hose
*Hydraulic motor rides under the gantry
*Engine moves carriage via a spool over which a wire is wrapped

'''Horizontal Dimension'''
*Set by guides that are rolled out with a single crank

'''Automatic Feed'''
*Separate hydraulic motor - with a riding bidirectional valve that trips its lever to other dimesion upon reaching end of track
*Wire drives carriage
*Have a safety trip in case of running into metal objects in wood
'''Dust Ejector'''
*On top of blade guard
'''Set Works'''
*Set relationship of saw to the log to make the next cut
*Dimensional sawmill needs setting in 2 dimensions
'''Log Holding'''
*2-stage dogs - one for staring the log (high center of gravity), and second for low center of gravity
*May want to flip log if it's difficult to hold towards the end

==Outstanding Design Issues==
*Hydraulic hose cabling guide
*Multiple edger blades in future
*Crank edger adjuster

'''Action Points'''
*Saw collar
