在连杆两端打孔，一端安装衬套。 Drill holes at both ends of the connecting rod, install a bushing at one end.

衬套内径: 5mm, 外径: 10mm

Bushing Inner diameter: 5mm, Outer diameter: 10mm

步骤 5：安装同步带轮和连杆 Step 5: Install Synchronous Pulleys and Connecting Rod

在大同步带轮 (60齿) 上打孔安装螺丝。将小同步带轮 (20齿) 固定在电机轴上。将连杆通过螺丝固定在大同步带轮上。 Drill a hole on the large synchronous belt pulley (60 teeth) for a screw. Fix the small synchronous belt pulley (20 teeth) onto the motor shaft. Fix the connecting rod to the large synchronous belt pulley with a screw.

步骤 6：制作垂直轴支架管 Step 6: Fabricate Vertical Shaft Holder Tube

切割并打磨金属圆管。在管上开槽，并打孔安装插销。 Cut and sand metal tube. Make a slot on the tube and drill a hole for a pin.

步骤 7：制作上锯片夹持件 Step 7: Fabricate Upper Saw Blade Clamp

制作金属夹持件，用于固定锯片上端。 Fabricate a metal clamp part to hold the upper end of the saw blade.

步骤 8：制作机身主体框架 Step 8: Fabricate Main Body Frame

切割并粘合多层塑料板，形成“C”形的机身框架。 Cut and bond multiple layers of plastic sheets to form the "C"-shaped frame.

步骤 9：固定驱动机构到底座和框架 Step 9: Fix Drive Mechanism to Base and Frame

将电机/驱动机构底座固定到机身框架底部。使用螺丝加固连接。 Fix the motor/drive mechanism base onto the main frame base. Secure connections with screws.

步骤 10：制作并安装工作台面 Step 10: Fabricate and Install Work Table

粘合多层板材制作工作台面，修剪并打磨边缘。在中心为锯片开孔，安装衬套。 Bond multiple layers for the work table, trim and sand edges. Drill a hole in the center for the saw blade and install a bushing/insert.

步骤 11：将工作台面固定到底座 Step 11: Fix Work Table to Base

在底座上打孔，安装衬套，然后用螺丝将工作台面固定到底座上。安装橡胶脚垫。 Drill holes on the base, install bushings, then fix the work table to the base with screws. Install rubber feet.

步骤 12：安装垂直轴和锯片机构 Step 12: Install Vertical Shaft and Saw Blade Mechanism

将垂直轴穿过上下轴承座，连接连杆。安装上锯片夹持件和弹簧，调整锯片张紧度。 Insert the vertical shaft through the upper and lower bearing blocks, connect the connecting rod. Install the upper saw blade clamp and spring, adjust the blade tension.

步骤 13：制作并安装控制箱 Step 13: Fabricate and Install Control Box

制作控制箱外壳，安装并连接 PWM调速模块 (电流 10A, 电压 12-40V)、电压显示屏、开关和接线端子。 Fabricate the control box enclosure, install and wire the PWM Speed Regulation Switch (Current: 10A, Voltage: 12-40V), voltage display, switches, and terminals.

步骤 14：最终组装并连接电源 Step 14: Final Assembly and Power Connection
