   I first saw a sample of that lighter-weight MDF about 5 years ago. I believe it's made with fibers of western white pine, but I don't know that for sure.

   Yes, there is such a thing as HDF--fiberboard comes in a whole range of densities. Here's an industry site that can probably answer your questions in more detail:

   *Light weight MDF does exist and it's a great product for some applications. It's trade name is TruPAN Ultralite. The material is made in Chile from radiata pine trees. It's texture and workability are pretty much the same as the MDF you are used to, but it's substantially lighter, so you don't have to have a friend help you lift a sheet onto the table saw. If you want to learn more about the product check out http://www.trupan.cl/. Hope that helps, Clay Baker, http://www.workingbetter.com

   *We have been playing with tru-pan for a few years in the university shop where I teach. Nice stuff, if you have the right application.Most tools hardly notice it. Very easy on tools. Cuts, routes, and sands with hardly any effort.Hates water. Don't EVEN try a water based finish on it. Will expand and contract with humidity changes.Will break easily. Find an application that put no bending stress on it.Very consistant in thickness, at least in my experience.The best use I've found for it? Experimenting on.Dave

   *Yea it does exist, i just used some like everyone has said its just like reg. mdf but lighter and it does chip easier so be careful in handliing it especially after you milled it

   *What it's about is...is not breaking your back lifting and moving it! Seriously though, we have used it in 3/4" thickness and it seems to machine the same,keeps it's edge etc., but it requires more finish appication, it seems to soak up more,requiring more coats.
