看到的一些关于铜桨的资料，分享一下，健康第一：-
Before going any further, it is imperative that before you start working with beryllium copper, you fully understand the health and safety aspects of this material. Beryllium copper ("BeCu") is toxic, and in its solid form presents no great hazard. The danger lies in the dust that is produced when BeCu is worked or machined. BeCu dust causes serious lung damage and is carcinogenic. For this reason, it is strongly recommended you do not use power tools to prepare BeCu propellers, as the last thing you want in your workshop is a fine mist of particles in the air that you will end up breathing in, and that will persist as dust for months or years. 开工之前，你要搞清楚铍铜合金对健康的影响，铍铜合金固态形势下，它并无害，而当它成为粉末的时候，它是有毒的。铍铜合金粉末会对肺部产生破坏，并且它致癌。由于这个原因，修整铍铜合金浆叶是不要用暴力工具，你最不想要的就是在你的工作室里到处都是铍铜合金的粉尘，而且这些家伙会残留几个月甚至几年。 I keep a seperate set of files for propeller preparation, and do most of the work on my propellers using various grades of wet-and-dry abrasive paper used wet, as the water flushes the wet-and-dry clear of dust and also traps the dust in the water. Also, files tend to clog easily when working BeCu, and can cause deep scratches. If I can avoid using a file, I do. However, to remove a large amount of material from the blades of a propeller you need to use a file, swapping to wet-and-dry for final finishing and balancing. 我准备了专用的锉刀来修正浆叶，很多工作我都会把砂纸打湿再来使用，水可以避免粉尘。同时，锉刀经常会打磨过了，从而留下很深的痕迹。我尽量避免使用锉刀。但是打磨掉大量的金属，你需要交替使用锉刀和沙纸。
