Using Treated Pine - What is the "H" rating?

I needed to purchase some treated pine for 2 different projects. One was for some internal framing, which I wanted to protect against termites, and the other was for a gate post which would be outside and in the ground.

After talking with my local timber merchant I found I needed "H2" for the internal and "H4" for the outside gate post.

Here is a list of the different "H" ratings and their applications:

"H1" : To be used indoors, above the ground. Not resistant to termites.

"H2" : To be used indoors, above the ground. Resistant to termites.

"H3" : To be used outside, above the ground. Resistant to termites.

"H4" : To be used outdoors, in ground or ground contact. Resistant to termites.

"H5" : To be used outdoors, in ground with water contact. Resistant to termites.

"H6" : To be used when in constant contact with salt water.

Hope this clears things up a bit when deciding on the timber you need for your next DIY project. Make sure to ask your timber merchant for a more in depth description and application for each type.

Rapidrench - Adjustable Ratcheting Socket

There have been many new tools released that promise to replace multiple tools in your workshop, but this one - the Crescent Rapidrench -  looks like it can do just that.  This one tool can (to a certain extent) replace a complete socket set. Here are some spec's:

• 7/8" adjustable jaw opening to accommodate 38 different bolt/nut sizes
  
• R2 RapidRench works on various fasteners and sizes
  
• Jaw design extends into deep areas
  
• Tool exceeds ANSI specs
  
• Comfort grip for reduced stress on hand
  
• Chrome finish for durability and corrosion resistance
  
• Reversible ratcheting mechanism

At the moment this new tool seems near impossible to find here in Sydney, Australia.
