Broaches from Colonial Tool Group Inc. We pride ourselves on the services we provide, relationships we build with our customer base and our world-class products. For all products manufactured, we help our customers achieve the lowest cost per piece by educating you on the best practices for your broaches and by providing in-field service staff, technical resources to assist in trouble shooting, and consultation on part processing, machine evaluation, handling etc. Colonial has the capacity to manufacture tools as small as 6mm in diameter to as large as 300mm. One of the most common broaching operations is cutting splines or serrations in machined holes. From standard involutes to special splines, Colonial is the supplier you want to help you achieve the lowest cost per piece. These broaches are used to finish round holes to close tolerances with good surface finish. Implementing our own patent #4850253, we can hold +/- .005mm with a .4-micrometer finish.
Toggle Clamp Sanding Block I made this quick-release sanding block from four pieces of 1/2-in. -thick birch plywood. The top three pieces are glued together. Wrap a quarter sheet of sandpaper around the bottom piece and slip on the top assembly. The toggle clamp (www.rockler.com #20787, $9) locks the top assembly to the bottom. All four pieces measure 2-1/2-in. wide by 7-in. long. Introduction to Machine Tools This document will introduce some of the basics of machine tool use for prototype fabrication. There are graphics and sections of video that can be accessed throughout the document. After brief explanations of some machining operations there will be hypertext links to short (about 30 second) video clips. All links in italics access video.

Advanced Tool Sharpening Many people create HSS lathe tools using nothing more than a bench grinder and get perfectly acceptable, if not downright excellent, results. For most normal sized projects with moderate tolerances that may be all you'll ever need. As tolerances get tighter, or improved surface finishes are required for decreasing part sizes, better tools are needed. You can't shave tenths and simultaneously get a great finish with a dull tool. My goal is to show you some practical techniques that can quickly be applied to improve the edge quality of your tools. It should be mentioned that my focus is exclusively on generating extremely sharp edges and you can't blindly apply that type of tooling to every situation. So when do you need these tools? When there's a need to control size at the tenth level or below. The exact details of what happens when we "cut" metal is also outside the scope of this page, but the reader is encouraged to do some additional research. Crusty Old Machinists The Shear Tool
Scientific Cutting Tools :: The Cutting Edge Tools - Tailstock DRO - Academy of Lagado Tailstock Digital Read-Out [March 10, 2014][March 23, 2014 - note][April 5, 2014 - addendum][May 12, 2014 - note][Aug. 24, 2014 - Model 2] This project is not original with me, and is in fact based on a very similar project by George Race. For a link to that project and other related projects look here (scroll down to Tailstock > Depth Gage). Revised Model 2 This revised Model 2 was made because the original Model 1 was interfering too much with the compound rest. This new design moves the DRO to the top of the tailstock. A measured drawing is available for Model 2 at the links below: To make it easier to bend, the aluminum flat stuck was held in a vise and bent before it was cut to length. The back of the DRO was removed, and two mounting holes were drilled and tapped for socket cap button head screws. The clamp to hold the end of the DRO was made by re-using the clamp from the Model 1; this required the clamp to be milled down to fit the revised application. Original Model 1 Quill Bracket
Eco Gadgets: DIY Battery Made From Recycled Aluminum Can - Ecofriend Eco Gadgets: DIY battery made from recycled aluminum can Eco Factor: Portable battery made from old aluminum can, saltwater and charcoal. The billions of batteries discarded every year pose a serious threat to the environment and to the scarce freshwater reserves, which provide potable water to billions of people. Rechargeable batteries do reduce the scare but not as much as environmentalists would really love. Instructables user “Egbertfitzwilly” has posted a nice DIY which allows you to make a battery at home using commonly available materials. The battery uses a casing made from a recycled aluminum can, electrodes of copper and an electrolyte made from burnt charcoal and a saltwater soaked sponge. Enjoyed this post?

Learn CNC - CNC Information | Learn CNC | CNC Programming G-Code Little Did I know… There was a steep learning curve with CNC. Building a frame for the machine is only a small part of the project. Today it is much easier. For some reason I figured if I just build this machine it would spit out parts whenever I wanted it to. Other things I had to learn along the way: CAD Software Designing Parts CAM Software Preparing parts for machining Simulating Machining Machining Basics Cleaning parts So, where am I at today? Today I have multiple CNC machines that I work with.
Micro 100 Tool Corporation Shop Made Tools - Page 104 I have went through all 133 pages of the postings and there is a wealth of information here. Some of the items are flat incredible and kudos to their makers. Mine is much more modest though I find it quite handy.I don't know if power tapper is the correct term for this tool and the tool certainly is not original with me. Previously I made a version of this to hold the little 1" diameter dies and I finally got around to making the tap version. I re-purposed the black anodized handle. Many years ago the handle was being discarded at work and being the pack-rat I am I hauled it home.
Notes on Sprockets and Chains A sprocket is a toothed wheel upon which a chain rides. Contrary to popular opinion, a sprocket is not a gear. Chain Construction Chains have a surprising number of parts. Chain Dimensions Chain types are identified by number; ie. a number 40 chain. The roller diameter is "nearest binary fraction" (32nd of an inch) to 5/8ths of the pitch; pin diameter is half of roller diameter. Plate thickness is 1/8th of the pitch, except "extra-heavy" chain, which is designated by the suffix H, and is 1/32" thicker. ANSI Standard Chain Dimensions Bicycle and Motorcycle Chain Dimensions Selecting a Chain Two factors determine the selection of a chain; the working load and the rpm of the smaller sprocket. Maximum Pitch = (900 ÷ rpm ) 2/3 The smaller the pitch, the less noise, wear, and mechanical losses will be experienced. Sprockets There are four types of sprocket; Type A: Plain Plate sprockets Type B: Hub on one side Type C: Hub on both sides Type D: Detachable hub Pitch Diameter = P ÷ sin (180° ÷ N) Back

Socket and Screwdriver Bit Organizer | ToolGuyd Lee Valley has started carrying a rather interesting tool storage system that consists of a tool board and repositional adapter pegs. The tool boards are made from ABS plastic and measure 7-1/2″ x 11″. You can mount them to horizontal or vertical surfaces, such as the wall or your benchtop, and can also place them inside drawers and tool boxes. Each board has 450 1/4″ slots. The recesses can fit standard 1/4″ hex screwdriver bits without needing any additional accessories, and optional adapters are made to fit 1/4″, 3/8″, and 1/2″ square drive sockets. You can also buy tool clips that are meant for holding tools such as screwdrivers and other small cylindrical hand tools. There are ribs on the inside of each slot to ensure that screwdriver bits, adapters, and tools won’t wiggle loose as you move tools to and from the board. Prices: $6.50 for each tool board, $3-4 for 12 socket adapters, $3.50 for 6 pairs of tool clips. Buy Now(via Lee Valley) Related Posts: Craftsman Unimax Tool Set
