Anyone make / use a stamp mill?

My local yard will not do this as far as pound per pound trade. Lucky you.

Over the years I've developed good relationships with most of the yards but still manged to sour one yard.

I cut up a large Bucyrus for scrap, it had a Cummins KT-450 engine and the yard was hoping this engine was coming in on a load of scrap.

That engine was pure gold.

Unless you have a proven claim that is producing high grade, just use a pipe mill to crush, test and produce samples for assay. I take mine into the field on expeditions to create and test samples right in the field. Build or buy a custom crusher once things are proven up. If your doing this constantly for mining claims then by all means buy or build a crusher.

How much does your pipe rod mill weigh?
Do you use a steel cable to mover your equipment in the forest / woods?

If you do use a steel cable how do you attach your
steel cable and use?

This would run one big stamp mill with a rod mill after it.

Found a chuck of 2" steel square stock for mounting a 25 pound hammer head on, both steel items where found at a scrap yard. Time to think about rollers as a guide for the square stock.

Did you buy or come across plans for your stamp mill?
Thanks.

I did come across this link / PDF:
Stamp milling a treatise on Practical Stamp mill and Stamp mill construction.

Darn looks like this link does not go there. Sorry.

Here is an interesting article which mentions the use of stamp mills…http://www.bodiehistory.com/milling.htm

In Africa they are quite common. Parts are readily available and you don't need to be a rocket scientist to build one.

Lucky you as in the USA they have not been made for a very long time.

If you had some good ore, should save a lot of time.

When I used to live in Northern CA I used to visit Auburn every now and then…If you are ever in the area you should check it out…https://en.m.wikipedia.org/wiki/Gold_Country_Museum

I remember that many years ago, they used to have an operating stamp mill on display at the fair…But that was so long ago…

Lots of stamp mill parts around if you know where to look. I know a lady out in Nevada that has one for sale.

Here's a local stamp mill from slate mountain mine that was restored. Running it with a tractor but sometimes they use a hit and miss engine.

A single or double stamp mill that is portable is a little more viricidal and portable then a stamp mill that weights many tons.

There are examples of single stamp mills out there the classic is using a Dolly pot with either a weighted lever or a bent over sapling to assist. The museum in weaverville has a hand crank one stamp mill. Most historical small 2 stamp mills are still fairly heavy even the tiny ones. The stamp faces and shoes were replaceable, the companies that made them are long gone so you would have to custom make replacements.

Mass / weight will make the stamp mill more reliable and effective. The hand crank stamps where effective for sampling for general assay use. With todays improvements in fabrication / welding the small hand crank sized units should be easier to both build and refurbish after a ton or a few tons of material.

Some people still use a sledge hammer after all even today. A small stamp mill would reduce this work factor even if it last for just a ton of material.

A stamp mill is not always needed however it is a option for some areas and thus the interest.
