Nicely organized and with a realistically stepped set of demonstrations, I learned quite a bit, adding some new wrinkles to experience in hand (from coppersmithing). Also useful was to see that stuff I'd learned the hard way, through much T-and-E, eventually was on the right track, and so was a confidence builder.
I would've liked more on stretching and shrinking in the formation of compound curves (usually referred to as 'saddle shapes') than was offered.
I've found Covell's DVDs consistently helpful, feeling I learned quite a lot from all of them. He's methodical, well-paced, projects confidence in his work process obviously built on long practice. He is sensitive not only to catch, but also to articulate; when timely, numerous (seemingly small) details and wrinkles sometimes easy for novices to miss. He then illustrates how, when neglected, they can have significant negative impact on successful outcomes, whether when pattern-making (forgetting witness marks), allowing contaminants through hasty weld preparation, preliminary fitting-up, or in premature tacking of mis-aligned butt-edges. In this particular DVD, I would have liked a closer look at just how lever operated mechanical shinkers/expanders actually function, since the process both of shrinking and expending sheet metal, while involving a lot of brute force, has also a complimentary subtle side too. Not everything can be explained in one DVD; for instance, TIG welding demands a DVD all its own, but explanations of underlying principles can be a help in tool selection.
The video parts I was able to view were fine, however you sent either a damaged/inoperative disk. I returned it together with a request for a non-defective replacement. I want to review a later section but was unable to, as the disk stopped operating well before I reached the place (TIG-welding copper) for which I'd ordered the disk. I received and viewed this disk last year, and still hope to reach you by some means to repeat again my request for a replacement. William P. Reimann, Cambridge, MA.
