First off, I have loved your thread so far as it reminds me why years ago I went got my certs. It is so fun watching people discover their talents and developing their skills as they move along. Big props to you! I look forward to seeing this gantry completed,

Now, if I missed this somewhere in your thread please ignore, but when working with galvanized material you need to be especially careful as the by product of the zinc oxide coating coming off in fumes is the same chemical compound that was used in WWI nerve gas. It will destroy your lungs and in large enough quantity can lead to serious consequences. You need to keep your head out of direct fumes and good ventilation at all times.
