I apologize in advance for the basic questions.

 

A while back I bought a tumbler from Harbor Freight and some resin media.  It's a vibratory type with a roundish bin for the media.  I tumbled some old chassis with it, including brass womp and FCR and old flexi chassis.  It worked OK, but I guess I was expecting better and quicker resuilts.  It took several hours for each batch and some of the areas on each chassis weren't completely done.   I'm think that small media might have helped getting the crefvices better and maybe a different type like walnut shell.  I tumbled everything dry, but I read in this forum that some folks use water and soap with the media.

 

Is a cheap Harbor Freight tumbler sufficient?  Is resin OK for slot car chassis? if not what is better?  What about dry versus wet? and when would one use each?  I'd appreciate any information you're willing to share.

A couple need more work but it was a huge improvement

Looking back, I don't recommend doing a lot of individual parts with sharp edges like these

It just doesn't seem to do as good a job as when they're attached to a complete chassis.

Pablo-

 

1- What liquid soap did you use?

 

2- Can you get a new gasket for the tumbler?

 

Cheers

Dan..I have the same vibratory tumbler,,I tried the ceramic triangles ,but the walnut shells work the best..it's not recommended to use liquid in this tumbler as it goes to bottom killing the motor.

Buffalo Arms Thumblers Tumbler---Dawn dish soap in small qty--- ceramic media. I"ve been using the same stuff for 7 years now--works great and polishes everything very nicely in a couple of hours.  I usually leave it overnight though as it's easy to do and doesn't hurt a thing!  Nothing does a better job or any  easier!

With vibrators the walnut media is great.  Another option is adding brasso (or a similar product) to corn cob media.

I have used a lot of stainless steel media.  It's fine for many uses, including this purpose.  The reason you use stainless steel is because it's used wet.

Tide HE (Low suds potential) works also.

I learned that from the great Steve O'Keefe, a lifelong idol of mine. He made me realize important things in life, such as :

I bought a Mid South Shooters tumbler and it blows away the Thumbler, by far! Bigger drum and way cheaper too! I also have the large Harbor Freight vibrator tumbler, it is the wet one, not as good. I use it to deburr parts. Would like to sell it......

Rick, are you bailing out of the "construction" business? I realize there isn't a fortune to be made in it but you are one of the best! :)

Thanks for the input everyone.  I appreciate it.

 

I think I'll get some walnut shell media and try that for now.

Why does it "blow away" the Thumblers tumbler? Do you have one? Sounds like you've got the cheapo harbor freight which is junk! The one I saw on the website was $180.00. Which model did you get?

My Thumblers tumbler is $163.00. ????

It much larger and way faster. I have an AR12, I think is the number. Thumblers have gone up in price in the last couple of years.................

That's the current price from their website! I only paid $135 for mine delivered with all the media and solution. The "speed" of cleaning has more to do with your media than how fast it turns!  I wouldn't ever need one larger--I've tumbled 5 chassis at a time-- and it could do more. :)

My Thumbler was about $170 ( $185 now)  when I bought it and the Mid South , I paid $168. ( price now is higher, wait for a sale) The RPM makes a HUGE difference in time, it really does. Mid South could prob hold 10-12 chassis.............

Ok, that's actually a Frankford Arsenal brand.  I like the tumbler body on that one.

You bought the WRONG Thumbler's Tumbler!!  That's all--- should have got the large RED one.  It's cheaper and does a much better job!! :)

 

It's the Thumbler's Model B  Tumbler!! Not the one you have!!  :)

 

It's like anything--the right tool for the job works great!!

I just purchased a Frankford Arsenal tumbler from Cabelas. I had a bunch of club points that have accumulated, so I figured this was a good way to use them.

 

Still experimenting with what media works best with what metals.

 

More later!
