I have a very old thumblerDonated from 75 year old friend that his dd used when he was a teenager. How do you tell if you have a low or high speed? Are there certain amount of RMP's that I can count?

The "high speed" models are 300 rpm. (and I personally don't believe the high speed is needed)

Default Low-high speed, pro-con.

So for those whom would be buying a rotary tumbler, (or replacing an electric motor). What would be the the positives and negatives on low-speed- V.S. high speed motors. Please let me hear of theory's and experiences.

Ya'll got me curious. I've had my Thumler's Tumbler for nearly 40 years. Replaced the Canadian motor some years ago. I just looked and the motor nameplate reads RPM/TPM 1550. 115 volts, 1/50 hp.
I think TPM is turns per minute in Canadian.
When I bought this it was listed for lapidary use.
On their website it is listed as model B with a 15 lb capacity The others are much smaller and I would not consider them for brass.
At least 100M has gone through mine. Mostly pistol, but plenty of rifle.

Bradam -

The only wet tumbler I've ever used is the Thumler's Model B high-speed. Here is a description of the RPMs taken from the STM website:

"This is the High Speed heavy-duty version of the Model B Thumler's Tumbler, using the 1/30 horsepower 3000rpm motor to clean your brass fast when using stainless steel!"

An earlier post by 25-5 says the speed of the older Thumler's is 1550 RPMs. Having never used an older Thumler's, I can't compare the two in terms of tumbling time and results.

The description from the STM website infers tumbling time is faster with the hi-speed tumbler over the older model but I would be interested in hearing from those with personal experiences in both models for a statement of comparison.

Low speed or High speed. Which motor did you install?

I have the hi-speed, but 25-5 installed the low speed from his description.

I replaced the motor with one of the same specs. I was not aware of a high speed option. I have no need for it anyway. I tumble with dry media and a few fabric softener strips with a timer set for three hours. They come out clean and shiny. If I want real shiny I add brass cleaner. Since I shoot them and don't photograph them, I skip that bit.

I see that 25-5 uses his low speed Thumler's for dry tumbling. I'm not sure what difference the motor speed makes when wet tumbling.

If anyone knows, maybe they can chime in and inform us.
