About Us


 On the cutting edge of milling technology, we are IC WOOD (Inner Circle Wood)!


Hollow Logs and Radial/Annular Lumber 

We are an Up-State NY based start-up company that uses patented technology to manufacture Hollow Logs and Round Lumber. 

In the beginning we weren't quite sure how Hollow Logs and Round Lumber would be used. But shortly after showing our products at an international woodworking fair we quickly realized we had made something completly new! 

We now supply products accross the nation to a wide variety of distributors and non commercial customers.  We also provide consultation and support for those wishing to start their own Round Lumber business. 

 Every product we sell comes from hazard trees that are taken down in cities and towns of Up-State NY.  We make it our business to be good caretakers of our planet by re-purposing downed and hazard trees. 



We supply logs for many Mammals, Reptiles, Birds, Insects /Bees...

Endangered Species,  Vertebrate and Invertebrate,  to Zoos all accross the USA!





We supply natural play elements for dozens of Schools, Parks, Residential Customers, and Playground Distributors!


Bark Free 24"x36" Knotty Pine Log 

Seen here below is a core taked directly out of a log, notice it's relative smoothness even without sanding or finishing. The same texture can be expected on the inside of our hollow logs. 


 We have sold drum shells and Round Lumber in over 20 countries around the world!


The process is so efficient that very little is wasted, notice the picture below and the concentric annular lumber all from the same log chunk!



With this exceptional hollowing technology we create very little waste,  we actually remove the core of the log in 1 solid piece which can be cut into concentric pieces of round lumber. 



Just to recap, what are hollow logs and round lumber used for?

  • Natural Playscapes, Natural Playgrounds, Crawl Log Tunnels

  •  Zoo Animal Enrichment (puzzle feeders, hollows, natural nesting logs)

  • Animal Furniture (cat tree, dog house, pet cave, natural retreat)

  • Nesting Boxes (hornbill, porcupine, etc...)

  • Garden Planters (with plastic insert or natural)

  • Architectural Support Members including Pillars and Columns

  • Specialty Lumber /Staves/Furniture/Building material

  • Log Treehouses

  • Drum shells, Slit Drums, Hollow log caskets

  • Speaker boxes




Why would Zoos want hollow logs?

A diverse array of animals ranging from primates to armadillos use Hollow Logs for a wide variety of applications including nesting, climbing, hiding, scratching, and exploring.  ICW offers Hollow Logs to encourage the natural behaviors that animals exhibit in the wild.  Stimulating species-typical behaviors through enrichment improves the well being of animals in captivity and improves the success rates of species reintroduction and captive breeding.


Currently many animal care-givers obtain logs hollowed by natural processes. These naturally-hollowed logs are decaying and may contain harmful fungus, disease, and insect infestations.  Besides, it is difficult for zoos/others to even find enough of these natural hollows to satisfy the needs of their animal enrichment programs. 

Why would you use logs in a Playground?

 "Natural playgrounds" are play environments that blend natural materials, features, and indigenous vegetation with creative landforms to create purposely complex interplays of natural, environmental objects in ways that challenge and fascinate children and teach them about the wonders and intricacies of the natural world while they play within it.[citation needed]

 The technological age has changed the ways in which children play, arguably contributing to childhood obesity. It is therefore up to parents, communities and schools to re-introduce to children what it means to play in the outdoors.[9]

 Play components may include earth shapes (sculptures), environmental art, indigenous vegetation (trees, shrubs, grasses, flowers, lichens, mosses), boulders or other rock structures, dirt and sand, natural fences (stone, willow, wooden), textured pathways, and natural water features.[10]


Kids are Enriched by natural log hollows!



Real logs stimulate creativity and mental well-being by introducing texture, color, smells and the all natural feel of real trees.  Our Natural Crawl-Through Tunnels give kids a unique opportunity to explore wood as never before.  They get to see wood grain, growth rings, and even get to see what a tree looks like on the inside as it grew!  Bark, wood grain and the smell of real wood make our Hollows and Rounds a great option for kids to explore.



Naturally Kid Safe!




Why you solid wood/log be used for Speakers or Drum Shells?

Aside from being aesthetically pleasing and unique, using actual tree rounds as speaker enclosures is beneficial to the overall speaker design because it results in an almost seam-free cabinet, thick and acoustically dead enclosure material, and non-parallel internal sides which help to reduce unwanted frequency amplification and reverberation.

I think that the appropriate question to ask here is not "why build speakers out of a tree", but rather, "why not"?

** Where do we find logs?

There are many ways to find chunks of log and tree trunks. In the past we've found our logs in landfills,  craigslist ads, and also word of mouth. Finding logs this way is a great way to get free or cheap logs for hollowing. However currently we've found the easiest way to aquire recycled logs if from tree service companies who take down hazard trees in villiages and cities.  

Here is one of our main suppliers:

* International Society of Arborists



If you're wondering what the diffence between what ICW makes and what natural decay/pests make here is a little comparison:

Naturally-Hollowed Logs vs. Natural Hollow Logs


"Naturally-Hollowed" tree hollow or tree hole is a semi-enclosed cavity which has naturally formed in the trunk or branch of a tree. These are predominantly found in old trees, whether living or not. Hollows act as a resource or habitat for a number of vertebrate and invertebrate animals.  Hollows may form as the result of physiological stress from natural forces causing the excavating and exposure of the heartwood.  Forces including wind, fire, heat, lightning, rain, attack from insects (such as termites or beetles), bacteria, or fungi.  Also, trees may self-prune, dropping lower branches as they reach maturity, exposing the area where the branch was attached.  Many animals further develop the hollows using instruments such as their beak, teeth or claws. (Wikepedia 2014)


"ICW Hollow"   man-made tree hollow, the result of a new milling technology.  ICW has developed an eco-friendly patented technology for creating Hollow Logs and Round Lumber from solid log chunks.





Hollows Around the world

 Conservation of hollow-using fauna is an issue in many parts of the world. In North America, recovery of the Eastern Bluebird (Sialia sialis) has required nest boxes due to the loss of natural hollows. The scarcity of dead, hollow-bearing trees in Scandinavian forests is a key threatening process to native bird life. In Sweden, almost half of red-listed species are dependent on dead hollow-bearing trees or logs.[1]


 In Australia, 304 vertebrate species are known to use tree hollows in Australia: 29 amphibians, 78 reptiles, 111 birds, 86 mammals.[2] Approximately 100 of these are now rarethreatened or near-threatened on Australian State or Commonwealth legislation, in part because of the removal of hollow-bearing trees.[1][8]


Threats to hollows include: native forest silviculturefirewood collection, rural dieback (such as frominundation and salinity), grazing by cattle, and land clearing. Additionally, pest and introduced species such as the Common Myna and Western honey bee (Apis mellifera) compete with native species for hollows; domestic and feral cats and black rats prey on hollow-using animals and have been damaging especially to island populations; and some native hollow-using species have increased population densities or expanded their ranges since European settlement, such as the GalahCommon Brushtail Possum and the Little Corella and compete with less common native species.[1]


Asian Black Bears, also known as Himalayan bears (Lat.: Ursus thibetanus), in northern parts of their range, such as Russian province Primorye, China, and both Koreas, prefer spend winter periods in large tree hollows, where females also give birth to cubs. Threats include massive deforestation in these countries, combined with direct poaching of wintering bears—with selective destruction of the best hollow trees.[9] In Russia, attempts (sometimes successful) are made to restore such broken trees.[10]Unfortunately, only a small portion of all damaged trees can be restored in Primorye, where forests are basically logged without taking to account needs of large fauna.
