8-28-2013 Project #3

Centers



Tonight I started my third project. Here is a shot of the technical drawing:



 This one got a little more technical in that I used the cutting tool in two different positions. The object was to make two pendulums. The photo below shows both  pendulums. The one on the right is the bigger of the two and is complete. The one on the left shows half of the part milled. The part milled will become the pointed end, while the other end will become the shaft.


Here is another shot of the completed pendulum standing up on end:


Tuesday, Sept 3, I will finish the 2nd pendulum and show you what it looks like in comparison to the first one.

August 28, I finished the other pendulum:

8-27-2013 Project #2

Step Shaft



Tonight I started my 2nd project and got 3/4th finished in 3 hrs time. Getting better.

This project is called a Step Shaft

Here is a detail showing what it will look like when done:


And here is a photo of what it looks like after tonight's work:


Tomorrow evening I will finish the 2nd side (bottom end in photo). I have a 0.40" piece to mill and then I have to deburr the edges at the end.


8-26-2013 Project 1 Completed

Tonight after spending about an hour in the classroom going into book material, we went out into the shop to continue work on our Project. Here are photos of my alignment rod that I finished:

Project #1:

Tonight I created my first cutting tool bit and then learned how to use a lathe and started on my first project. 

Here is a photo of my first cutting tool I created:


Once this was done, I moved on to my first project. The first project is an Alignment Rod:


Here is the result from the first night of cutting done after I made the cutting tool:

(End view showing first section milled)

Tonight (8-21-2013) I finished one half of the rod:


Here is a close-up shot of the end:


Not bad for a guy who has spent the past 23 yrs designing architectural plans on a computer. Next week I get to do the other side of the rod.

Welcome!

The process known as Machining:

"In the process known as machining, a machinist is a person who uses various types of machine tools to make or somehow modify parts, generally metal parts. This is done by using machine tools to cut away materials and produce work. Machinists produce work that conforms to a specific set of instructions such as engineering drawings, pr blueprints. Within the title of machinist, there are specific skills that are need for job positions such as die maker, tool maker, pattern maker and mold maker."

"Machinists use metalworking equipment, such as lathes, shapers, grinders and saws, to form either unique and carefully shaped individual pieces, or multiple pieces of specifically tailored metal. Machinists work for large concerns that use metal in their final products, such as heating-vent manufacturers or automobile factories, or they work for specialty shops that take specific orders for needed parts and equipment. Machinists must be able to read blueprints and be familiar with laser and optical measuring devices that can test the degree of precision of their work. Some specifications call for shaping a piece of metal to within one-one-thousandth-of-an-inch accuracy. Machine shops usually employ between four and fifteen machinists, so those who work in this part of the industry should be comfortable working in close quarters. Machinists often know more about the metals they work with than do the clients who order pieces made from these metals. The machinist can and does act as an advisor, if the client makes false or misleading assumptions about the materials being used or the finished product. Quality machinists have good vision, endurance, an eye for detail, excellent hand-eye coordination, a love for quality and precision, and respect for the tools of their trade. Working with metals can be dangerous for someone who is careless or easily distracted. Indeed, the biggest concern with being a machinist is the daily threat of serious injury. Few professions place employees in such regular contact with high-powered and potentially destructive tools. Surprisingly, however, the average injury rate in this profession is only slightly above the national average. Machinists must wear protective safety goggles and earplugs, and they must carefully decontaminate themselves after working with high-viscosity lubricants, as many of these lubricants are quite toxic. These worries, however, only slightly diminish the satisfaction machinists derive from shaping something out of nothing in an expert and craftsman-like way every day." (www.princetonereview.com)

I started attending Wallace State Community College this past Monday, August 19, 2013 in the field of:
Machine Tool Technology

On this blog I will be sharing with you photos of my projects and metal creations I make during my Course of Study.

Enjoy! Updated weekly. Comments welcome!
