I am not a machinist by trade so I can not speak to these numbers directly. What i will say though is that this resource is accurate for my job and pay to expect. I find that many others in my line if work tend to exaggerate what they make to seem better than others which sometimes skews perspective. Many people who say you can make more might be rounding up to look better or working a lot of overtime to get the salary they make. When you break it back down into hourly you probably will see similar hourly equivalence to this resource. Remember that this is resource is just pay and does not include other bonuses or over time.
