The milling on the frame pieces is complete. I added half-lap joints to all of the parts so they lock together flush. As seen in the left side of this image. I just need to drill and tap the front and back pieces. I'll go back to the machine shop tomorrow to get the L-channel aluminum cut. So far the plan of doing all of the machining myself is going quite well. I don't see anything else in the project that I can't accomplish on my own. The machine shop simply has some really expensive tools that make certain tasks much easier, and now that I know how to use them I can just chug along.
