e********t 发帖数: 9607 | 2 我有jig saw和circular saw,切直线我从来都用circular saw,快又直。jig saw只有
在薄板上锯孔我才用。
我只切过shoe molding的斜角,shoe molding只有半寸高,circular saw从上面一刀就
能切断。
如果需要切更高的base molding,比如3寸高的,可以平放着用circular saw切,
circular saw的锯片最大可以调到跟水平面倾斜45度角。 |

h*****t 发帖数: 6890 | 3 有一次拍 Harbor,回来发现照片上有水的反光。新手,呵呵。我经过学习,才知道需要
加上一个 circular polarizer。
我想给我的 Nikor 50mm f1.4G的头配一个这样的filter试试。前面有个贴子说 B+W的
好,我分不清哪种较好。
1. B+W 58mm Circular Polarizer with Multi-Resistant Coating, $74
2. B+W 58mm Kaesemann Circular Polarizer with Multi-Resistant Coating, $98.
99
3. B+W 58mm XS-Pro Kaesemann Circular Polarizer with Multi-Resistant Nano
Coatin $92.99
请大家给给建议。 |

h****z 发帖数: 2009 | 4 在装laminate,买的circular saw锯不动,只好用手锯,一晚上锯两条长边就不行了,
而且锯不直。买过一个电动circular saw,手持不好控制。另一个电池的circular saw
,根本锯不动。大家给推荐一个吧。 |
|
w*****g 发帖数: 3922 | 5 这个问题有点泛,但也不得不问。
我想铺个大概500sqft的laminate,底下带pad的。看了一些视频和书,觉得自己可以做
。省钱省不了多少,但可以练练手。
基本工具就那些,但因为要横向和纵向切割地板,所以需要用Circular Saw。因为之前
需要一直比较心灵手巧,但从来没有做过这种活儿,所以家人担心我用Circular Saw会
有潜在的危险。
现在想听听用过Circular Saw的朋友,用这个对于一个纯新手来说,是不是有比较大的
可能割到自己。或者有没有什么可以替代的工具来切割?
另外铺laminate是否如视频上一样的简单?有没有更多的trick和tip需要做了以后才能
体会到?
谢谢谢谢。 |

e********t 发帖数: 9607 | 6 任何电动锯子都有危险性。circular saw如果保证锯片够锋利,一般情况是安全的。
circular saw带个扳机,你必须一直用力扣着它锯片才转,好像table saw和miter saw
是一直都转的(没用过不敢确定)
circular saw安全的保证是工件用木工夹子夹在桌子或者锯马上,尽量不要完全靠手力
按着工件,一个夹子就几块钱,但是能使工作变得安全、高效、准确。 |
|
C*******d 发帖数: 15836 | 7 至从我买了Miter saw之后,就从来没用过circular saw。不过如果你要是割一个大板
子,还是要用circular saw的。
对于快速精确切割小方子和板子,Miter saw绝对更好,对于强调便携或大板子切割,
circular saw必不可少。 |
|
z*********n 发帖数: 94654 | 8 circular saw便宜,其实不矛盾
买了miter saw还可以买circular saw
问题是,想图便宜能不能买了circular不买miter,呵呵
决定还是买齐了,呵呵,工具对头事半功倍,对于上班族,时间就是金钱
省出来的时间去打球爬山比啥都好

还有 Circular Saw 可以控制 切口深度, Jigsaw 不可。比如,除旧地板,Circular
Saw 可以调到 只切 3/4“ 而不伤 Subfloor, Jigsaw 就用不上。 |
|
j******a 发帖数: 552 | 10 circular saw:轻便手持,可以上下左右到处锯,但锯缝不太平整,深度小,手持需要
一定的力度稳定,注意安全。
miter saw: 重,摆在水平面操作,切缝平整,适合切角度,因为锯片大所以切缝深,
操作方便,安全,效率高。
最好都用110v,够劲。活多,质量要求高,miter saw必备。活少,circular saw。
circular saw很便宜,两个都买最好。 |
|
y****i 发帖数: 12114 | 11 切大板子还是table saw安全些。
circular saw切大板子,就算不提安全隐患,要切直也不太容易的。
circular saw的优点一是便宜,二是哪儿都能用用(万金油型的工具),缺点就是危险。
在电动工具里,circular saw的危险程度高于table saw(从前是table saw最危险,但
是table saw的技术改进了不少,比从前安全多了)。
电锯这东西,除非你买那种不切手的电锯,不遵照安全规范使用,都是危险的。
做好防护,在良好的工作空间使用,使用正确的锯片,遵照规范使用,用的时候集中注
意力,电锯也不危险。 |

j***b 发帖数: 5901 | 16 Circular saw is more useful, because you can carry it to site and make cuts,
instead of making cuts first and then carry lumber to site.
Circular saw is not as precise as miter saw for certain purpose, but if you
are handy, it can be made to be precise enough. |

Light rays which are reflected by any surface become polarised and
polarising filters are used to select which light rays enter your camara
lens.
• They allow you to remove unwanted reflections from non-metallic
surfaces such as water, glass etc.
• They also saturate colors and increase contrast.

g*****9 发帖数: 4125 | 43 You need a miter saw and table saw (cut long side)
Or you can can get a large radial arm saw that can cut both directions (RWKR
favorite)
Anything with a cord will be powerful enough for what you need.
If all your cut ends and sides are going to be under trim pieces (baseboard), you can get away with only a corded circular saw. But takes some practice to cut length wise.
