I recently purchased a Donegan OptiVISOR. The lenses are made of glass and are available in six levels of magnification, from 1 1/2 to 3 1/2 times. The level of magnification affects the focal length, that is, the distance from the lens to the work for proper focus. I chose a 1 3/4 magnification that has a focal length of 14″. A 3 1/2 magnification has a focal length of only 4″. When choosing a lens, it is important to consider both the level of magnification required and the focal length of the lens. The lenses are precision ground and polished to the same standards as eyeglass lenses.
The frame is constructed of sturdy plastic. The headband size is adjusted by turning a knob at the rear. The front of the headband is covered in leather where it touches the forehead.
I will use this tool for precision soldering and other miniature repair work. These are proudly made in the USA.
This book will not teach you how to hammer a sheet of steel into a vintage car body. It is more of a utility type book. Basic sheet metal forming to make boxes and other useful shapes is what you will find inside. The book starts with tools and shop safety.
How to plan and layout a project is covered in detail.
Methods for forming and joining the sheet metal are discussed. There are also some project plans, including a simple bending brake that can be built from hardwood.
There are 112 pages with lots of illustrations and useful information. I thoroughly enjoyed reading the book. My copy was purchased from Amazon…
I purchased a Harbor Freight 6″ belt and 9″ disc combination sander many years ago. I didn’t like the included stand, so I didn’t use it. My sander has been sitting on the floor for a long time. I finally decided to build a proper stand. I used three 24″ pieces of 2″ x 4″, 3/16″ wall rectangular tube that I cut with my bandsaw. I cut a 9 1/2″ x 15″ piece of 1/4″ plate with my metal cutting circular saw.
I welded the stand together.
I painted the stand with Krylon® spray paint.
I drilled and tapped 1/4″-20 threads into the bottom of the feet. I attached rubber pads, 2 on each foot, using 1/4″ screws.
Before mounting the sander to the stand, I changed the motor mounting bolts to 3/8″ x 1″ carriage bolts. This allows for adjusting belt tension without wrench access to the underside of the sander.
I mounted the sander to the stand using M8-1.25 bolts screwed into the factory holes in the base of the sander. The wheels set just off of the ground. The sander is tipped up onto the wheels to move it around. The heavy steel makes a very stable base.
