Sawmill Design 2

What if we use steel sections to eliminane need for building a track?

10x4" I-beams in the 20 lb/ft range are available - see PDF page 132 in Structural Steel Sections

Use 30" hydraulic cylinders for y and z motion in a cantilevered configuration along the steel section x axis. Absolute simplest design is obtained, if 40 and 20 hp hydraulic motors are used for a 20" and 10" sawmill blade.

High performance, 60 hp sawmill at about $1000 in parts. Another breakthrough, as similar power costs at least $25k.

Calculations

[Hydraulic motor power] = torque (in-lb)*RPM/63k

• Take [5000 RPM, 166 in-lb motor] for

Bill of Materials

• Four .6" hub v-groove bearings - $25 each
