Well, it's been almost two years since I promised to do this (http://www.arboristsite.com/showthread.php?threadid=4177), but I've followed through and developed a log calculator for handheld computers. As I was finishing, I heard Arbormaster came up with their own, but I'm still happy to have finished this.

It's for free. It's easy to use. Just download and put on your Pocket PC and open with Pocket Excel. It works on desktop computers too that run Excel or a compatible spreadsheet program.

To use it, just enter the tree species ID number from the second sheet, enter the log length and diameter, and the formula spits out the weight in pounds. If you want it in kilos, that's easily changed....but you can do that yourself. :)

Are there any other programs that I should work on? In the past week, I've written an extensive database program that allows someone to enter in a day's work (customer, crew, arrival/departure, travel/prep time, unbillable time, work performed, material and equipment used, etc.) and have reports printed easily, ready to send to the customer with a bill or show to the bank.

If my dad asks me to (and he has), I can show him every hour and instance where someone was shoveling, pruning, salting, blowing, mowing, raking, etc. I can display the number of hours X employee has spent traveling and preparing. It's really awesome what databases can do!

Anyways, I'm working on a lot of new stuff now, especially for handheld computers, and I'd love to get input on what industry people would like to see and use.

I get a pop-up saying "file format is not valid". Thanks anyway Nick. Now build us a robot to handle all of the wood.;)
 
Stumper, you can view it using the Excel Viewer from Microsoft. It's free from their website: http://www.microsoft.com/downloads/...49-91DA-4110-8595-4A960D3E1C7C&displaylang=EN

Maybe a LEGO robot....

Just so you know, the data is from the back of the rigging book that accompanies the Arbormaster video series. There are some other species in there that I found from a firewood chart, but I'm not supremely confident with those numbers. Those are marked by a "?" in column C of the Species sheet (it's hidden by default). The biggest improvement I could make would be to add more species and weights, but I'd have to find a better green wood weight table.
 
I'm not too sure about the weight on the osage orange..I deal w/ this wood alot and its as heavy as anything else if not heavier...Your chart seems to calculate it as being quite light though.....?>>:confused:
 
Great sheet, thanks Nick! Glad to see you roll back in here, especially after all i read!

Seeing as ya asked............. A fall force calculator in feet and pounds? Or some kind of speed chart per foot of drop, to use as multiplier for different weights in pounds?

Been wanting one of those for a while! That, this log weight calculator and the leverage of lean calculator at TB would make quite a combo, and come closer to the ArboMaster Software perhaps?

Thanx Nick,
(and for the Excel viewer link too to pass on)

Yeah...I'll have to check those things out. I'll be happy to pull out my Physics textbook and see what formulas I should use. My brother is also in advanced Physics, and I can just ask him.

Osage-orange is one of those that was not in the printed tables, and I used the weight I found on a University website, but I think those weights are undervalued.

Edit: I deleted those trees and reposted the file.
