Abbreviated Transcript:

00:07 In this video I machine my version of the "Impossible" Dovetail. This is a popular woodworking project, that I learned about from watching Jack Houweling on his YouTube channel.
01:06 One of the key things required for the project to succeed, is that the parts be able to fit together regardless of how they're oriented when they go back together. For that to occur, its critical that the initial stock be perfectly square,
01:46 A quick check over at the other corner confirmed the alignment of the spindle, and then I made a start on removing the bulk of the waste stock. Now the way I'm choosing to tackle this project means that it hinges on the availability of a narrow taper dovetail cutter to remove the rest of the stock.
02:30 There's a lot of contact with the work piece, and it's both conventional and climb milling at the same time, which is far from ideal. But it did a great job, and had no trouble cutting through the soft aluminium, in fact it took out most of the waste stock in a single pass.
02:47 One small negative was the little burr at the top which suggests its rubbing rather than cutting at the very top of the cutter. But other than that, the rest of the cut was quite good, and a quick clean up pass on each side, left an excellent surface finish.
04:11 The walls of the cut were ok, but the bottom surface was a bit ordinary, and nowhere near as clean as the aluminium. In any case, the end result was adequate for the project, and the two major pieces came together quite nicely.
04:3 The burr on the brass piece was making the fit a little tight, so again some 120 grit paper sorted that out, and the fit was much improved.
06:26 Once the diameter was sorted, I parted off and then used these gravers to form the dome section on the other end. The final piece to make is the stand, which I started by roughed out the basic shape on the scroll saw.
07:45 Its a bit of extra work, but its a very convenient way to get small shapes into position for soldering, that might otherwise be difficult to hold in place as they're heated. Now the brass sheet is supplied with a hard temper, so its already work hardened.
