Thumlers make some serious tumbling equipment. The MP-1 sits somewhere between the toys reviewed on our site made by other companies and the Thumlers a-r1 model (also reviewed).
We would class the MP-1 as a top of the range entry level model to the world of tumbling. Primarily this is due to cost and size. Whilst it’s not a traditional full 3lb capacity machine (rather a 2lb barrel is included which is slightly larger than the 3 children models) its cost is slightly higher and indeed pushing on the boundaries of the full 3lb models by both thumler and lortone.
It is an ideal starter kit for anyone wishing to embark on a new hobby as it contains the grits and polish required to complete a full cycle. The drive belt and wheel are fully exposed, whereas on the real toy models, the moving parts tend to be covered for safety – which is another reason we say it stands apart from those tumblers classed in the kids range.
It runs quietly (with exception to the rocks knocking around as usual) – and is simple to operate. The exposed bearings make it very easy to maintain with a couple of drops of oil on the bushes from time to time to keep it running without wear and tear.
In summary this is a small tumbler – not a toy – but not quite hitting the mark as a professional useage device.
