I am a novice to the world of machinery and related hydraulics, but I am investigating the idea of attaching a small (3.5ft to 4ft) rotary mower to the end of a rubber-tired backhoe, to be used as needed in place of the bucket. Think in terms of a poor man's batwing mower...
If anyone can...
I am wanting to attempt attaching a small rotary mower, powered by hydraulic motor (not PTO), to a rubber-tire backhoe in place of the bucket (such that I can change from mower to bucket as desired). I am trying to make a poor-man's batwing mower, realizing all of the limitations of my desired...
Greetings.
Does anyone have experience with TDR for geotechnical applications (e.g., detecting shear plane in a borehole)? Or perhaps TDR knowledge and microcontroller interfacing?
I am looking into designing a SIMPLE, portable system for use in the field. I would appreciate any suggestions...
Railroad rails have been used for years on highway embankment failures as a method of repair, with the rails functioning similarly to cantilever beams/piles. Rails have standard 39ft lengths and come in different weights: 130-133 lb/yd and 136-140 lb/yd.
Assuming proper embedment into rock or...
I am seeking information concerning the application of surface, shallow geophysics to highway and roadway projects. In particular, I am interested in electrical resistivity methods and typical cost estimates. I am somewhat experienced in the use of electrical resistivity, but not so much for...
I am contouring data points (water level elevations in monitoring wells) using Surfer 7.0, and ultimately incorporating the contoured data into AutoCAD LT. My current procedure is as follows:
I generate a Post Map/Contour Map Overlay in Surfer, then export as a DXF file.
I then open the DXF...
I want to learn how to copy an existing Layer (Layer1) in a drawing (LT2000i) into the same drawing as Layer2. I am not able to do this no matter what I try.
Example: Existing layer with contours and data for 1999, to be saved as a different layer ("copy", different name for 2000)...
I wish to know of any rules of thumb for staying away from (or getting close to) residential and commercial foundations during shallow (less than 20 feet) excavating.
I frequently need to excavate contaminated soil in the vicinity of buildings, and do not want to undermine or otherwise...
I have searched previous posts and have not found an answer to my problem. I wish to copy a layer within a drawing (LT 2000)and save it within the same drawing. As an example, I want to copy "May Water Levels" and save it in the same drawing as a layer named "June Water...

I am plotting values of Sodium (Y-axis) against values of Calcium (X-axis) in a X-Y Scatter Plot in Excel (no trendline).
I wish to apply a "label" or identification for each of the two sources of data (i.e., the ID of each well from which the two data sources were collected). I am...
Regarding typical electrical resistivity profiling or sounding, I need to determine the contact resistance between a metal electrode inserted into the earth and the earth material itself. I am sure there is a way of doing this with a DMM or megger. However, I am unable to do this with a DMM...
Forgive me if this is an improper forum for my question. I would like to determine which popular PIC microcontrollers, including the BASIC Stamp(tm), are most suitable for incorporating into datalogging and similar projects. I am interested in assembling dataloggers to sample temperature and...
I am in need of a simple field test for determining the contact resistance of probes/pins being used in electrical resistivity investigations. I need to determine the contact resistance between the probe/pin and the surrounding earth material. This would apply to the non-automated type of...
