Tumbling Questions

[J Tiers]

The HF triangular media works the best on rust removal,w/o alter the shapes or threads.

That stuff is so BIG that it seems virtually useless on many things. The triangles are well over a half inch in size, IIRC. The case hardware I referred to earlier was only 2x or 3x larger than those huge triangles.

I would expect them to be unable to reach into any but the coarsest threads or details, threads for 5" dia bolts, for example. Anything smaller looks like it would be battered into pulp in a tumbler. A good amount of liquid might prevent the worst of the battering.

They make round media, square media, triangle media. Big, small, huge, tiny. There is a "right" size for every task.

1/2" triangle media is great for larger parts or heavy grinding.

In your application Jtiers I would have used a round cylinder shape 1/8 by 1/16th. Rice-media I call it.

Very good.

But the other poster described HF (Harbor frieght) media and the only ones they ever have in stock are the huge ones.

In fact, looking at their website, they only list two types in "tumbler media" ...... big triangles, and "spark plug media", which appears to be grit. But they do also have walnut shell media (which they list as "blast media"). They also list a couple types of "resin" (plastic) shapes, listed for for vibratory cleaners.... if you look harder, they have rock polishing abrasive.

I don't suppose they even know what the stuff is used for...... or they would offer different options, and list appropriate stuff in each category. Their tumbler is tiny, and they list it for "rock polishing".

Problem is... Harbor Freight.

I'll see where we order ours from, tomorrow.

No sweat..... there are sources here in town.....

But as long as sand from the shed does the job, I am unlikely to get too excited about them

Yah think HF is a problem?

I have used these, gets into all the nooks and crannies.

Also, use a tumbling soap.

I am "somewhat disappointed" with the quality of certain things I have purchased from them including the engine hoist that failed under load and the hydro-press that came unwelded under 1/10th load.

That however, would be a rant or 400 for another day.
