DIY帶鋸、平麵銑和sawmill

1.Sawmill

看了Wood-Mizer LT28開圓木，有如刀切黃油。該機是單臂懸梁結構，X軸是方鋼上下焊有1“圓鋼做導軌，鏈條傳動；Z軸也是方鋼外套滑軌用起重絞盤調高；Y軸是懸臂上裝電點火汽油引擎和帶鋸。帶鋸條是Raptor的0.042x1-1/4“x132”。下麵的Timbert M100也是同樣鋸條但鋸寬為26“，用subaru 7HP引擎，整機隻要3000刀。walmart 132"x0.035x1" saw blade $92.27:http://www.walmart.com/ip/11-ft.-Bimetal-Band-Saw-Blade-EA-1-79652CLB113355/46814061

油管有不少DIY的。目前看來，用廢舊摩托輪是較好的方案，似可借用其鏈條傳動，或直接用其汽油機。208cc/6HP電打火 150+28.5： http://www.northerntool.com/shop/tools/product_200638383_200638383

帶鋸，如555的鋸木速度是1500-3000FPM，另有建議鋸木/鋁為1000，鋸鋼/銅為100-150。電機一般為1725/3450rpm，減速比可取1：2或1：4。例如ebay 1"bore 2.5"OD pulley.
