First off, the second end plate was drilled today with some minor complications similar to the first. The major one being overloading the spindle on the mill/drill. I had not realized how much load was actually being put on the motor during the drilling operation until noticing the motor was too hot to even touch. To see how bad it actually was, I took a heat gun to it.
Well you live and you learn. Fortunately nothing ended up being fried but it is definitely not good for the mill/drill.
After drilling the plate, work was done on machining both diameters and chamfers on the barrel. This was done on the lathe with a boring bar in the quick change tool post. The raw barrel was not very concentric to start with so it was difficult to get it as centered as possible to make the cut. In the end it will work out but it was not where it should be in relation to the drawings. However, the two cut diameters and chamfers are concentric to each other as the first one was used and the clamping and reference point to machine the other.
