摘要：我已有一台较大的锯床，因此想再做一台轻便、便携且带有可倾斜工作台的锯床。我会用它搭配窄锯条处理小型工件，切割小半径曲线。而且我还能把它带到我们的俱乐部去。

看点：小型带锯机，可倾斜切割，切高170mm。

1. This is my third home made bandsaw (previous two). When I found Matthias's plans, it became clear that I should build a similar machine.

这是我制作的第三台自制带锯（之前还有两台）。当我看到马蒂亚斯（Matthias）的设计图纸后，我很清楚自己应该打造一台类似的机器。

2. I have a bigger saw and wanted to build a light, portable saw with a tilting table. I will use it for small work with a narrow blade to cut tight radiuses. And I can take it with me to our club.

我已有一台较大的锯床，因此想再做一台轻便、便携且带有可倾斜工作台的锯床。我会用它搭配窄锯条处理小型工件，切割小半径曲线。而且我还能把它带到我们的俱乐部去。

3. This saw is based on Matthias's saws, scaled to smaller size. I took some ideas from both of his recent saws. The saw has 220 mm wheels (8.5") and the cutting height is 170 mm. The motor is from my lathe, which now has a 3-phase motor.

这台带锯以马蒂亚斯的锯床为原型，按比例缩小了尺寸。我还借鉴了他最近两款锯床的一些设计思路。这台带锯的锯轮直径为220毫米（8.5英寸），切割高度为170毫米。电机是从我原来的车床上拆下来的，那台车床现在已经装了三相电机。

4. The frame is glued layers of spruce and is very stiff.

机架由云杉层板胶合而成，刚度非常好。

5. For the wheels I glued oak segments to the edge of a 18 mm plywood wheel. The rubber tire is glued after turning it round. The wheels are mounted on a 20 mm steel shaft with a pulley as a hub. The pulley is fixed on the shaft with a conical collet. On my big saw we made flanges, welded and turned on the shaft. It is much easier to use those pulleys for wheel hubs. Everything can be home made. I turned a recess for the wheels to support them and bolted them on with 3 bolts.

制作锯轮时，我将橡木嵌段粘在18毫米厚的胶合板锯轮边缘。橡胶轮缘在车削成圆形后进行粘贴。锯轮安装在一根20毫米的钢轴上，并用一个滑轮作为轮毂。滑轮通过锥形夹头固定在轴上。我之前的那台大锯床，是在轴上制作法兰、焊接后再进行车削加工的。而用这些滑轮当轮毂要简单得多，而且所有部件都能自制。我还车削了一个凹槽来支撑锯轮，并用3颗螺栓将其固定。

6. I also have rotating shafts on my big saw (as opposed to wheels rotating on fixed shafts). I have good experience with this. I made the upper wheel with a rotating shaft as well.

我的那台大锯床也采用了旋转轴设计（而非锯轮在固定轴上转动），这种设计的使用体验很好。因此，这台带锯的上锯轮我也采用了旋转轴结构。

7. My motor rotates counter clockwise as seen from the pulley, so I oriented the motor with the pulley on the back of the saw to get the right direction.

从滑轮一侧观察，电机是逆时针旋转的。因此，我将电机的滑轮朝向锯床背面安装，以确保锯轮转向正确。

8. The tilting table is supported with trunnions. The trunnions are supported from the right side. On most saws the front trunnion is held with a beam to the left of the blade, but it takes too much room in a saw this small and limits the cutting height.

可倾斜工作台由耳轴支撑，且耳轴从右侧进行固定。大多数锯床的前耳轴会通过一根横梁固定在锯条左侧，但这种设计在这么小的锯床上会占用过多空间，还会限制切割高度。

9. I can adjust the supports with 4 nuts on the right to get the blade to line exactly on line with trunnion pivot point.

我可以通过右侧的4颗螺母调整支撑结构，使锯条能精确对准耳轴的旋转中心点。

10. This was a very interesting project. Of course small saws can be bought very cheap, but this saw is much better in quality.

这是一个非常有趣的制作项目。当然，市面上能买到便宜的小型锯床，但这台自制锯床的质量要好多了。
