Maybe indeed Moorey! There’s lots of different types of media yet to try before I declare it not suitable for the type of work I had in mind for it. I’m prepared to persevere a bit.

They are commonly used in the restoration of Pinball machine metal parts as well and parts are usually in them for 3 or 4 days.

I've had the larger version of the tumbler for a few years and it's certainly not a perfect answer but I have found it very good at cleaning up brackets and fixings if given enough time.
Also found that adding the tumbler liquid seems to help the process.
Seems to work brilliantly on flatter surfaces - brackets, large bolts, washers etc., less so on intricate smaller parts but that mat be down to the media type / size.
I've left them in for a good 6 or 8 hours and quite happy with the results - always dubious about leaving something running overnight but may give it a go one day when feeling brave.
Size of the media makes a big difference - I found that recessed bolt heads etc. weren't good but then got some much smaller cones and results were then much better - downside being they easily get stuck in any nuts or recesses etc.
Haven't tried many other types of media yet but I have got a bag of walnut shell for polishing and some fine glass blasting stuff which may be good for more aggressive work (but not great for the tumbler itself!).
Cheers,
Andy

Good to know Andy! I am still experimenting with different media and times will post on here either way good or bad. I have been just following guidelines too from manufacturer. There are many different uses for these types of machines but they are probably not the number one choice for cleaning small parts. I thought I could be doing something else instead of dodging missiles from the old wire wheel! 🤣🤭

Had a very short spell in the garage yesterday due to other commitments but managed to reunite engine and frame.
