One clear message to take from that video, something that isn't always apparent to someone starting working with machine tools of any kind, is that you can often spend much longer making a fixture and setting up than you do machining. However, that fixture and set-up time are the difference between a successful job and one that flies out of the chuck or ends up with gouges across the workpiece where it slipped in the machine vice. Of course, a big lathe and 12" 6-jaw chuck also help!

Hi Neale, thank you for your thoughts. I see what your saying 100% I have never made the fixture type in question but lots along similar lines.
Many thanks

I like the idea, but it is a boring (not a deliberate pun) video. I would bore a big hole in the pallet and use a bullnose in the tailstock to position and hold the workpiece while you clamp it down. You can then check the original hole in the workpiece is central with a dial guage, if it matters that much.

Thanks mekanik, perhaps one day I will get a lathe. That would cause another project extending the workshop!
Many thanks

I think your Triac should manage it, my little benchtop CNC would, the trick is to get your tooling, feeds & speeds, DOC and cutting lube right.
- NickYou think that's too expensive? You're not a Model Engineer are you? :D
