Abbreviated Transcript: 0:00:08 I'm about to drill and tap some small retaining screw holes in this bezel, and I've got quite a bit of time invested in the part, so I'm taking it very carefully. 0:00:16 This wheel crossing jig is perfect for laying out the positions. The wheel is held on with double sided tape, and the holes and turning marks on the jig mean that it's easy to centrally position the work by eye. 0:00:37 A light center punch marks the hole locations, and then the work is positioned on the mill on a piece of melamine, so that it can float around and find its own center under the drill bit. 0:00:51 Now this mill doesn't have a depth stop, so I'm using the digital readout to control the depth, and the fine handwheel to move the quill. For a mid sized benchtop mill, it has quite a sensitive feel. 0:01:07 This hole is about 3mm deep, and I want the thread to go right to the botton, so I've modified this 10BA plug tap to be even shorter. It now has almost no taper at all and should give me what I want. 0:01:18 The light feel of the pinvise means I can tell if I'm getting close to breaking the tap, and it slides on this rod in the quill, so vertical alignment is sorted. A quick de-burr with a hand held countersink, and the job is done. If you'd like to see how these holes are used to fasten the chapter ring in place, then be sure to check out this other video. And if this is your first time visiting the channel, thanks for dropping by. 0:02:17 I'd like you to know that I post regular project videos about shop made tools, as well as a longer term clockmaking project, so be sure to subscribe. And have a look at the clickspringprojects website too, for more toolmaking project info. Thanks again for watching, I'll catch you on the next video.
