My British made tumbler is well over 30 years old and spares are readily available. It's still going strong although I've worn out several pots. I'll post a related picture soon that will make your eyes pop out. :D
Looking forward to the pics

I'll be interested to hear more when yours arrives.
I had an email today saying that my tumbler has now been despatched and I was given a Royal Mail tracking number! :D :Party:

Pardon my ignorance,but what should you put in the drum to clean coins and what is the difference in end result between a tumbler and an ultrasonic cleaner?

Good questions. I am shy of ultrasonic cleaners as I worry they can damage your hearing (without you realizing, until it's too late) - I know someone who may have damaged their hearing in this way. I plan to try some sharp grit, water, and a gnatsthimblefull of fairy liquid in my tumbler when it arrives. I don't plan to use it on anything of financial/historic value of course.

I’ll be interested to hear how you’ve got on with this beast.

Basically a tumbler/polisher cleans by abrasion, whereas an ultrasonic cleaner uses high frequency to pop little air bubbles on the surface of the item to dislodge crud.

I think it comes with a bag of something, but I may use some 10mm gravel? Though open to recommendations from those who know best. :thumbsup:

So theoretically a sharp sand might be ok?
I only ask as the word “abrasive”,concerns me slightly.It’d be interesting to see some before and after photos and what coins or artefacts may benefit from this?

Using sand or gravel works but produces dust and it will need to be replaced relatively frequently.

Apparently in the States, people use small stainless steel ball bearing as the media, and this cuts down the amount of dust significantly, plus they last much longer.
