Tumble-Bee 2 x 2lb rock tumbler vs Thumler's A-R2

Both are two-barrel rotary tumblers, but they are not the same size. The Tumble-Bee 2x2 runs two 2 lb barrels; the Thumler's A-R2 runs two barrels that hold about 6 lbs of rock each, with a fan-cooled, overload-protected motor built for continuous duty. Buy the Thumler's if you tumble often or in volume; buy the Tumble-Bee if you want a smaller, lighter machine for two small batches at once. No current prices were supplied for either, so compare store prices on each product page before deciding.

    What reviewers say

    Tumble-Bee 2 x 2lb rock tumbler

    Owners of Tumble-Bee rotary tumblers generally report steady, reliable running and quieter operation than plastic-barrel machines. The two-barrel layout is the main draw, letting people compare grits or materials in one session.

    Pros
    • Quiet running compared with many plastic-barrel tumblers
    • Durable rubber barrels and lids that seal well
    • Two barrels make grit-stage comparisons easy
    • Motor holds up over multi-week tumbling cycles
    Cons
    • Small 2 lb capacity limits larger stones
    • Belts and bearings wear and need occasional replacement
    • Long run times before results show

    Thumler's A-R2

    Owners of Thumler's rotary tumblers generally describe them as sturdy, quiet workhorses that last for years with basic care. Common complaints center on the slow rotary process and the small barrel size.

    Pros
    • Durable motor that runs for days without overheating
    • Quiet rubber barrels compared with plastic alternatives
    • Good results on small stones, coins, and brass
    Cons
    • Slow; a full polish can take four to six weeks
    • Small barrels fill quickly with larger rocks
    • Lid seals need careful tightening to avoid leaks

    Questions and answers

    Which is better for polishing large batches of rocks?
    The Thumler's A-R2. Each of its barrels holds about 6 lbs of rock, against 2 lbs for each Tumble-Bee barrel, and its fan-cooled motor is rated for continuous running.
    Which is better for sea glass and small stones?
    The Tumble-Bee 2x2 suits small material well, and its two 2 lb barrels let you run two grits at once. The Thumler's works too but is oversized for tiny batches.
    Can I run either tumbler for days at a time?
    The Thumler's A-R2 is rated for continuous operation and has a fan-cooled motor. The Tumble-Bee lists only a thermal overload protector, so long unattended runs are less certain.
    Which comes with more to get started?
    The Thumler's includes a grit pack with pellets and 5 lbs of mixed rock. The Tumble-Bee includes oil, an Allen wrench and a spare belt, but grit and rocks cost extra unless you buy its kit.
    Is the Thumler's worth more than the Tumble-Bee?
    It has roughly three times the capacity, a fan-cooled continuous-duty motor and starter grit and rock. Whether the price gap is worth it depends on how much you tumble; check current prices at each store.
    Which lasts longer?
    The Thumler's is built for continuous duty with a fan-cooled motor and is used in labs and industry. The Tumble-Bee is a lighter hobby machine, though its spare belt and overload protector help.
