Thread: A Heath Robinson Tumbler for under $30

So I did what any good "Near" would do ...... I redesigned it and came up with the Heath Robinson S/S Tumbler Mklll

Out went the caster wheels ....... And in came the skateboard trucks ($15 courtesy of a kids skateboard from the warehouse).

Also added was a stiffening board on the base of the bucket.

Once redesigned I have been able to tumble heavier loads while reducing the load on the wiper motor.

The Heath Robinson S/S Tumbler Mklll can take about 4kgs of the dirtiest of dirty and filthiest filthy range find brass.

And in a very short time turn it into the shiniest of shiny brass ready to be filled once again.
