Anyone know any good books for different measurments?

[Stu]

I basically wanted to know if anybody knew of any general books that had different measurments and conversions of timber wet and dry with different species with measurments like hoppus ft and m3 etc?

[Perkins]

I could do with that info myself.

All I know is that approx.28 hoppus foot hardwood or 32 hoppus foot softwood weighs 1tonne.

just to clarify...that's not "all I know"

Do you have the blue book? Forest Mensuration: A Handbook for Practitioners about 25 quid and it will teach you a lot of what you need to know. It's worth having the field guide one which is green as its waterproof and spiral bound for taking out into the woods.

 

Decimal Hoppus tables

Decimal cube tables

Top diameter tables

Yield class tables

 

There all good books to have.

 

It's worth getting your self a girthing tape in metric and an imperial decimal one (Hoppus) to take out and have a play with. A Clinometer is also a handy tool to have although they are expensive. You can use a cheapy compass clinometer which will do the same job. You do tend to get your eye in i recently looked at a stand of Norway and said 50' timber hight 65' total. Looked at it with the clinometer and i was spot on. When it was on the deck it came out the same too.

If you use a smartphone (iPhone, Android, etc) there are loads off conversion apps available in the app stores/markets at little or no cost.

Thanks.

 

I got mine from the treesource bookshop. They do the field guide too (which is the easier one to read first). The other books are mainly tables which make sense once you've mastered the techniques. If your boss has a woodland marked for felling (thats not been started yet) check the cubic meterage on the felling licence and go measure it on your day off and see if you come up with the same answer.

 

If your doing softwoods (you can do it with hardwords but its harder) you can work out the volume of each tree and know exactly what your felling.

I got the field guide, still complicated lol but im understanding it, how do you work out how much m3 you do in a day or is it just a random guess cause the way the contractor i work for does it is by weight

Practice practice practice, and experience.

During your breaks work out the volume of what you have cut. If it is logs the following formular is pretty accuarate:

pie* Diameter squared/40000 * Length.

 

If you are felling and snedding Table 11, page 112-113 in the forestry measurement book will give you whole tree volumes.

 

Between these two i have managed without getting bogged down, which is good as i is only a bear of very simple brain.

 

Good luck

seems like a complicated formula lol its hard to get your head around, do you have to use the mensuration book all the time to work out volume and can you do hard wood with it? i found the best bit of info was the chart that gave different weights for different species when freshly cut.
