Workmate Sawbuck by Tinkerjim on August 20, 2013
Food Living Outside Play Technology Workshop Workmate Sawbuck by TinkerJim on August 20, 2013 Table of Contents Workmate Sawbuck . 1 Intro: Workmate Sawbuck . 2 Step 1: . 2 Step 2: . 2 Step 3: . 3 Step 4: . 3 Step 5: . 4 Step 6: . 4 Related Instructables . 5 Advertisements . 5 http://www.instructables.com/id/Workmate-Sawbuck/ Author:TinkerJim Emeritus Professor of Mathematics. Intro: Workmate Sawbuck With two simple wooden crosspieces, a Workmate becomes a solid and stable sawbuck. Step 1: The jaws of the Workmate clamp and hold the sawbuck vee pieces securely. Step 2: These photos show in detail how the Workmate jaws hold the sawbuck pieces. They are gripped from above and below in a wedging manner and 'alternate' in such a way that great lateral stability is realized. http://www.instructables.com/id/Workmate-Sawbuck/ Step 3: The vees shown here were made from 13" lengths of good 2x4. They are actually "X" shapes with two short legs, the latter being long enough for the Workmate jaws to grip from below as shown in the previous step. The short legs on the prototype shown here are about 1-1/2" long. The angle between the legs is about 85° which is the largest angle our Workmate jaws would accommodate. Four 3" deck screws hold each crosspiece together - two from one side and two from the other. A tight clearance hole was drilled through the 'top' piece to preclude splitting which would adversely affect rigidity. Also, waterproof glue was used to ensure absolute rigidity (but mostly because this tinkerer likes to use glue !). -

Investigation of Feller-Buncher Performance Using Weibull Distribution
Article Investigation of Feller-Buncher Performance Using Weibull Distribution Ebru Bilici Forestry Department, Dereli Vocational School, Giresun University, Giresun 28950, Turkey; [email protected] Abstract: With the advancement of technology in forestry, the utilization of advanced machines in forest operations has been increasing in the last decades. Due to their high operating costs, it is crucial to select the right machinery, which is mostly done by using productivity analysis. In this study, a productivity estimation model was developed in order to determine the timber volume cut per unit time for a feller-buncher. The Weibull distribution method was used to develop the productivity model. In the study, the model of the theoretical (estimated) volume distributions obtained with the Weibull probability density function was generated. It was found that the c value was 1.96 and the b value was 0.58 (i.e., b is the scale parameter, and c is the shape parameter). The model indicated that the frequency of the volume data had moved away from 0 as the shape parameter of the Weibull distribution increased. Thus, it was revealed that the shape parameter gives preliminary information about the distribution of the volume frequency. The consistency of the measured timber volume with the estimated timber volume strongly indicated that this approach can be effectively used by decision makers as a key tool to predict the productivity of a feller-buncher used in harvesting operations.
