零成本全木制747模型制作过程
在小区看到几块装修木头废料，
碰巧刚看完乔-萨特《未了的传奇-波音747》电子书，萌生了做一架模型的念头，于是把木头捡回家。![](https://wkrtcs.bdimg.com/rtcs/image?w=544&md5sum=9c3a09b76b653a45b1bd2007110ba8b8&sign=2444244dcc&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","w":"544","h":"408","dataType":"jpeg","c":"word/media/image1.png","imgOriW":3264,"imgOriH":2448})
到了周末，先在网上找到一份相对清晰的图纸。
![](https://wkrtcs.bdimg.com/rtcs/image?w=431&md5sum=9c3a09b76b653a45b1bd2007110ba8b8&sign=2444244dcc&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","w":"431","h":"314","dataType":"jpeg","c":"word/media/image2.png","imgOriW":431,"imgOriH":314})
先把图纸在屏幕上放大到合适的大小（我放大到500%，刚好可以充分利用这几块木料）然后用半透明的纸蒙在屏幕上，用铅笔轻轻描下轮廓（如果有打印机的话，就更轻松了，缩放到合适的大小，直接打印），然后用剪刀按轮廓剪下，贴到木料上，再沿着纸样在木料上描下轮廓（不想用纸样的话，可以直接根据图纸的比例，在木料上画出轮廓，这样比较麻烦）。![](https://wkrtcs.bdimg.com/rtcs/image?w=541&md5sum=9c3a09b76b653a45b1bd2007110ba8b8&sign=2444244dcc&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","w":"541","h":"406","dataType":"jpeg","c":"word/media/image3.png","imgOriW":4160,"imgOriH":3120})
下一步就是体力活了，手锯锯下，木锉整形，最后砂纸打磨。

机身也一样，先锯出轮廓，然后用美工刀按照飞机的三视图削出立体形状。 747的‘驼峰’是其最明显的特征。747-400机翼上还有个小翼，直接用三合板锯出来，然后把机翼和小翼的结合处都用砂纸磨出45度角，增大粘合面积。

纸样和对应的零件
下一步，在机身上机翼位置，先用电钻钻出个小洞，然后把锯条伸进去，开槽（没有更好的电动工具了，只好这样开槽），水平尾翼则简单些，直接锯出一条缝，后期可以用小木料填补。

装上机翼后的样子。注意切割机翼的时候，翼根要多留出5mm，刚好可以插入到机身的开缝中。

全部部位用木工白乳胶粘合。
747有四台吊装的普惠公司的发动机。用木头直接削出来。用三合板锯出吊舱支架，用白乳胶粘合。然后粘到机翼下侧的对应位置上。

![](https://wkrtcs.bdimg.com/rtcs/image?w=546&md5sum=9c3a09b76b653a45b1bd2007110ba8b8&sign=2444244dcc&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","w":"546","h":"410","dataType":"jpeg","c":"word/media/image9.png","imgOriW":2560,"imgOriH":1920})
24小时彻底干燥后进行下一步：上油
用硬毛的画笔（我用的油画笔）把硬质木蜡油均匀的涂到机身上。这一步可以封闭木材表面的气孔，防止将来空气湿度随着四季变化时造成木头开裂变形。现在看到机身上已经有光泽了。（这张照片上4台发动机还未粘上）![](https://wkrtcs.bdimg.com/rtcs/image?w=546&md5sum=9c3a09b76b653a45b1bd2007110ba8b8&sign=2444244dcc&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","w":"546","h":"410","dataType":"jpeg","c":"word/media/image10.png","imgOriW":2560,"imgOriH":1920})
再下一步，用刷暖气片剩下的银浆漆均匀的刷一遍。
![](https://wkrtcs.bdimg.com/rtcs/image?w=541&md5sum=9c3a09b76b653a45b1bd2007110ba8b8&sign=2444244dcc&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=75&ipr={"t":"img","w":"541","h":"406","dataType":"jpeg","c":"word/media/image11.png","imgOriW":4160,"imgOriH":3120})
银光闪闪的样子。（刷过木蜡油和银浆漆后的毛笔可以用汽油清洗一下，否则干后就笔毛就粘接在一起不能用了）
换个清爽点的背景。下一步打算在机身上刻出机缝，舱门、窗口等细节，用颜料涂装一下。等涂料到手后再继续发帖。
缺点的话，就是有点匆忙，机身打磨不够，上漆后依然能看出有些坑洼。不过对于第一架静态模型，已经很不错了。爱因斯坦做的第三个小板凳才够及格好吧！

这架747让我重新体验到模型的乐趣，上小学时，最讨厌体育课，最喜欢手工劳动课，当时基本都是剪刀、胶水处理的硬纸板模型。上课时不但做自己的作业，还主动替其他同学完成作业。
747基本完工后，马上入手了一套简单模型工具和一辆虎式坦克，打算入坑。

对我来说，这架747真的是零成本。各种工具家里都有，白乳胶、木蜡油、砂纸是以前做家具时剩下的，银浆漆是上周重新刷暖气片时留下的。不过入坑后估计钱包会很受伤的。
目前仅仅开始素组，看时间和兴趣是否能持久下去，如果能继续，打算先买几罐油漆，学学手涂，真的烧起来的话，再过渡到全套的喷绘工具。
