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 ( #20787, $9) locks the top assembly to the bottom. All four pieces measure 2-1/2-in. wide by 7-in. long. HomeShopTech Getting Started Checking Basic Mill Setup © Frank Ford, 2008; Photos by FF Before you start to work with any tool, it's important to make sure that it is ready for your use. Unlike simple tools such as screwdrivers, hammers and wrenches that don't need routine attention, virtually all machine tools have loads of controls and adjustments that affect their performance. Particularly in a shared tool environment, it's important to check the equipment so you'll have a safe and productive work session. When you approach the milling machine, you might notice that the person who used it before you had changed some important adjustments. Vertical milling machines generally have adjustments for tilting the head both side-to-side and front-to-back. Clearly, there'd be no chance of drilling a vertical hole with the head in that position. Before starting a job where accuracy is at all important, it's necessary to make sure the mill head is aligned square with the table. Well, maybe not.

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

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

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.

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

Backyard Workshop - Home MIMF • View topic - Jason's vacuum thermoforming adventures While watching some youtubes of folks doing vacuum forming at home, I noticed some guys actually pressing the plastic down with gloved fingers to get edges pulled down completely. This seemed like a bad idea, as I was sure that it would create this spots or ugly deformities, but the plastic is already cooled enough that it's not a problem. I tried pushing the edges with a piece of wood, and it turned out pretty well. To improve upon that idea, I made a ring, just slightly bigger than the base of the pickup mold, to press the last 1/4" to 3/8" of plastic down evenly around the edges. This worked so well, that I busted out four more identical covers! This whole adventure didn't end up costing much. Not shown are some of the bigger failures, including blistering and tearing of the plastic, due to overheating. If I was going to do this again, I'd build a bigger table, maybe 12x12. Fire away with any critique or questions! -Ruining perfectly good wood, one day at a time.

DIWire desktop machine bends wire into 3D sculptures Over a year ago, Pensa Labs caught our attention with its impressive DIWire Bender, a small machine that bends thick wires into elaborate 3D shapes by following simple vector drawings. Since then, the company has been refining the wooden prototype we saw before into a sleek fabrication device that's fit for consumers. The result is a more compact, easier-to-use DIWire that can turn pieces of wire into creative 3D sculptures while sitting comfortably on a desktop. View all At about the same time it revealed its invention back in May 2012, Pensa Labs also made the DIWire's software and physical design openly available through its website. The new DIWire measures 16 x 10 x 8 in (40.6 x 25.4 x 20.3 cm) and operates as easily as most desktop printers. After connecting the DIWire to a computer via USB, users simply drag and drop an SVG file into the included software to get started. For now, you can watch to video below to see some of the inventive creations that can be made with the DIWire.
