ORIGINAL: EgosumDominus Quite often I feel as though I am wasting my time with these posts. Try to give professional advice to someone that needs help...and low and behold..people with bad advice show up with suggestions I made very clear as to why one should not do that. But lets get a little further into the reasons for my thought process. Galvanized pipe is toxic. As my early post stated, dont use pipe with the galvez process. It will rust over time. But I did not say that it is toxic and has been related to cancer, lung desease, birth defects etc. For that I regert. Welders for the most part will not touch it. Many welders have died from Galvez poisoning...builds up in the system and kills your ass. And thats the end of science class. Sorry to be so harsh, but its peoples health I am concerned about. Including yours. As a welder Myself, I understand the toxicity of galvanized steel, it's also why I pointed out that the material I was recommending is such after your initial post. In this application though, and the frequency in which I, Myself, have to replace gear, the threat of adverse reation or contamination seems minimal. And in the spirit of this conversation, I'll go on to point out (as a furniture design major whilst in college) that there are many woods that are quite toxic. So, to add to the safety issue, We shall now address that factor in considering gear construction (due to the penchant to use wooden handles as an insertable object). Please stay away from any plywood, most all plywood contains formaldehyde. Blackwood, ebony, and cocobolo can be very toxic. Which kind of sucks, because ebony is such a wonderful and weighty material. Also unfortunate exclusions are teak, wenge (dammit!), and rosewood, which is crappy for this kind of application anyway. Padauk, a rather pretty deep orange wood with great grain and weight/feel (it's almost waxy) is very toxic. I learned this firsthand after a student was using an orbital sander on a piece and the shopmaster flipped on all the dust-collection systems and closed the shop for an hour. Not to mention that harvesting such woods sometimes contributes to the deforestration of our planet's rainforests. Keep in mind that even machining these materials is ill advised by any woodworker as the dust is pretty gnarly.
