Slater Atlas Stone Mold - How it all started

 

My name is Steve Slater creator of the Slater Atlas Stone Mold.

 

In 2001, a man named Knut Bjorvatn (pronounced Canute Beovoten) and his friends from the Cincinnati Strongman Club inspired me to design our Atlas Stone Molds. Knut had the first set of Atlas Stones that I have ever laid eyes on, or should I say left my skin on, as the stones were pretty rough.

 

A few years later, Knut moved back to Norway, and I purchased four of his atlas stones. The lightest out of the four Stones weighed a massive 255 lbs. All was fine, until I went to shoulder the stone during my upcoming competition training. Struggling in doing so, I started to research how to make a lighter stone. After brainstorming, with strongmen, machinists, foundry workers, concrete specialists, contractors, employees, and customers at our family hardware store, I came up with a way to create nice, lighter atlas stones by using the now developed Slater Atlas Stone Mold.

 

The first stone I made was about 176 pounds, and worked very well for me and the local strongmen to shoulder for reps. As I started to make more stones, I sometimes caught myself becoming a little obsessed when it came to making stones; Trying to discover the best techniques to create a first class product. Eventually, I was able to produce atlas stones that are smooth, with just a little texture on the bottom. This is for added grip, along with a slight flat spot so they do not roll away from you.

 

 Starting in 2003, I was asked by Dr. Terry Todd, the director of the Arnold Strongman Classic, to make the woman's world record stone. This stone would weigh 300 lbs, and would eventually be lifted to a 36" platform by a Texan lady named Jill Mills, the Worlds Strongest Women at the time. This Stone was made from an 18" Slater Atlas Stone Mold with lead added to the center. This lift took place on stage in the Greater Columbus Convention Center, as an exhibit during the Arnold Strongman Classic competition. This stone is now on display at the Joe and Betty Weider Museum, located in the H.J. Lutcher Stark Center at the University of Texas.

 

In 2007, The Manhood Atlas Stone Lift was introduced into the Arnold Strongman Classic Competition. Dr. Terry Todd once again give us the challenge of making the world record atlas stone. The previous world record atlas stone was 511 lbs., set in 2003 by a Hungarian named Laszlo Fekete. A round lead core weighing over 200lbs was added into the center of a 21" Slater Atlas Stone Mold, making a 522lb stone (11lbs. heavier than the previous world record). The core was so heavy that it had to be supported in the mold by attaching a tripod onto the core, suspending it into the center of the mold.  We then poured extremely strong concrete mix imported from Denmark into the 21" diameter mold, surrounding the massive insert. The Denmark mix was the strongest mix available; With the PSI of over 16000lbs. Using this concrete made it not only the heaviest Atlas Stones in the world, but also one of the strongest.

 

Steve McDonald from Pennsylvania was the first to set the world record over a 48" bar. In 2008 we added more lead to bring the weight of the stone to 525 lb. Zydrunas Savickas of Lithuania set the a record of 3 times over the bar within 60 seconds. In 2009 for the Arnold Strongman Classic, we added even more weight to bring the stone to 529lbs. Travis Ortmayer, known as the Texas Stoneman, put the massive stone over the 48" bar once in a world record time of 13.01 seconds. In 2010 Brian Shaw of the USA came to the Arnold Strongman Classic to amaze the strength world by placing the now 533lb stone over the bar 3 times in 53 seconds. Derek Poundstone did the same in 60 seconds and the “Stone Man” Travis Ortmayer did it in 82 seconds. From Russia, Misha Koklyaev placed the stone over once in 17 seconds.

 

Paul Uhl, director of the Fortissimus World Strongman Challenge, chose to use Slater Stones for the competition. He has graciously named the stone event the Slater King of the Stones World Challenge. Now, our stones are used in the Worlds Strongest Man Competition, Americas Strongest Man, and have been featured on the Today Show twice. 

 

In addition to providing stones for competition, many of the best strongmen personally own our stones. Derek Poundstone, a world champion strongman, is the owner of a 555lb Slater Atlas Stone made from a 21" Slater Atlas Stone Mold, which he hoisted over a 46.25" bar in 22 seconds. Travis Ortmayer owns a 600lb Slater Atlas Stone. 2011 Worlds Strongest Man Brian Shaw is the owner of a 629lb Slater Atlas Stone which he has lifted. All of these world record stones were made from the 21" Slater Atlas Stone Mold.

 

Although we are enlightened to create stones for the world’s strongest men, it gives me great pleasure to make stones for whoever has the desire to train with Atlas Stones, no matter their level. This being said, this is why we manufacture in all sizes; To appeal to those at any strength and conditioning level.

 

I remember the excitement I felt the first time I lifted Knut’s atlas stones. A bit of this excitement goes into each and every Slater Stone Mold and Slater Stone made, for anyone that has the determination to give this raw form of training and competing a go.

 

 

We offer accessories so you can make a certain stone size weight either lighter or heavier than just a concrete stone. You will see weight guidelines with both foam and lead added. The foam we use in the form of balls are manufactured from high grade marine foam so it will not break down and will continue to hold up in the stone. If you would like a custom foam insert made please let us know. We use lead as a weight comparison because you can use more concrete in the mix increasing the strength of the stone. You may purchase lead ingots from many plumbing suppliers also. We always suggest that if you use an insert or add anything into the stone it is best to add our Concrete Strengthening Fibers to the mix for added crack resistance strength.  You may view the Density Comparisons of Heavy Materials list at the bottom of the page to see different weight comparisons. For many added stone making  tips check out the new How to Make Atlas Stones DVD.
