四、钻排孔法 用手电钻,装夹尽可能大的钻头,从方木中间排着钻孔(见图二),孔与孔之间二交量为钻头直径的2/10左右。在方木全长上钻完孔就相当于在中间铣了一个长槽,方木即被分为两半。再用扁铲一类的工具,在方木两侧将其撑活动,直至取出。笔者用此法曾从300mm厚的钢板上掏过梯形窗口,应用得很顺利,故用此法起取锤砧座周边的方木当无问题。
Four, drilling row hole method With a hand drill, the largest possible bit of drill bits, row of holes from the center of the wood drilling (see Figure 2), the hole between the two cross-hole diameter of about 2/10 drill bit. Drilling holes in the full length of square wood is equivalent to milling a long groove in the middle, square wood is divided into two halves. Then use a flat shovel a class of tools, on both sides of the square wood will hold its activities, until removed. I use this method has been drawn from the 300mm thick steel trapezoidal window, the application is very smooth, so use this method to take the hammer around the anvil wood when no problem.
