Routers for Router Tables New-Breed Models Spare You the Expense of a Router Lift
Compliments of Fine Woodworking TOOL TEST Routers for Router Tables New-breed models spare you the expense of a router lift BY ROLAND JOHNSON ABOVE-TABLE ADJUSTMENTS MAKE THE DIFFERENCE A table-mounted router can be very versatile. But it’s important to choose a router that’s designed expressly for that purpose. The best allow both bit-height adjustments and bit changes from above the table. A router that makes you reach underneath for these routine adjustments will quickly become annoying to use. 54 FINE WOODWO R K in G Photo, this page (right): Michael Pekovich outers are among the most versatile tools in the shop—the go-to gear Height adjustment Rwhen you want molded edges on lumber, dadoes in sheet stock, mortises for Crank it up.

That gives more precise control over a variety of work, us- ing bits that otherwise would be too big to use safely. A table allows the use of feather- boards, hold-downs, a miter gauge, and other aids that won’t work with a hand- held router. With a table-mounted router, you can create moldings on large or small stock, make raised panels using large bits, cut sliding dovetails, and much more. Until recently, the best way to marry router and table was with a router lift, an expensive device that holds the router and allows you to change bits and adjust cut- ting height from above the table. -
Practical Implementation of the Stream Function Method for Design of Arbitrary-Geometry Gradient Coils
Practical Implementation of the Stream Function Method for Design of Arbitrary-Geometry Gradient Coils R. A. Lemdiasov1, R. Ludwig2 1Insight Neuroimaging Systems, Worcester, MA, United States, 2ECE Department, Worcester Polytechnic Institute, Worcester, MA, United States Introduction Over the past several years a variety of theoretical design methods for the construction of gradient coils have been developed. For instance, in [1] D. Green et al. minimize a weighted combination of power, inductance, and the square difference between actual and desired field. Representing the current as a Fourier series they find optimal coefficients that minimize the cost function. Our work is a continuation of last year’s research reported in [2]. In this paper we describe an alternative implementation of a stream function method to design gradient coils. Using this method we are able to determine the current distribution to achieve a prescribed magnetic field distribution in the Region of Interest (ROI) that is largely independent of the shape of the current-carrying surface. We will demonstrate the successful implementation of our approach as well as experimental results. Theory As mentioned above, a cost function Φ can be introduced in the form K Φ = 1 ()() ()− ()+ 2 +α ∑W rk Bz rk Bdes,z rk Boff ,z Wmagn (1) 2 k =1 () () where W r is a weight function, BZ is the z-component of the total field, Bdes,z r as well as Boff,z are the z-components of the desired and offset magnetic field, and α Wmagn is magnetic energy with being a weight coefficient. In (1), the first term denotes the square deviation of the magnetic field from the prescribed field, and the second term is the magnetic energy of the coil. -

Hand Saws Hand Saws Have Evolved to fill Many Niches and Cutting Styles
Source: https://www.garagetooladvisor.com/hand-tools/different-types-of-saws-and-their-uses/ Hand Saws Hand saws have evolved to fill many niches and cutting styles. Some saws are general purpose tools, such as the traditional hand saw, while others were designed for specific applications, such as the keyhole saw. No tool collection is complete without at least one of each of these, while practical craftsmen may only purchase the tools which fit their individual usage patterns, such as framing or trim. Back Saw A back saw is a relatively short saw with a narrow blade that is reinforced along the upper edge, giving it the name. Back saws are commonly used with miter boxes and in other applications which require a consistently fine, straight cut. Back saws may also be called miter saws or tenon saws, depending on saw design, intended use, and region. Bow Saw Another type of crosscut saw, the bow saw is more at home outdoors than inside. It uses a relatively long blade with numerous crosscut teeth designed to remove material while pushing and pulling. Bow saws are used for trimming trees, pruning, and cutting logs, but may be used for other rough cuts as well. Coping Saw With a thin, narrow blade, the coping saw is ideal for trim work, scrolling, and any other cutting which requires precision and intricate cuts. Coping saws can be used to cut a wide variety of materials, and can be found in the toolkits of everyone from carpenters and plumbers to toy and furniture makers. Crosscut Saw Designed specifically for rough cutting wood, a crosscut saw has a comparatively thick blade, with large, beveled teeth. -

February 2004 Fleam
True Japanese Dovetail Saws 2 new rip-tooth dozuki saws are efficient dovetailers. utting dovetail pins and tails is primarily a ripping C operation. So it has always bewildered me that almost every Japanese saw sold for dovetailing had teeth designed for crosscut- ting or cutting plywood. A few specialty importers do sell Japanese backsaws with a rip- tooth configuration, but these are made mostly by hand and cost between $140 and $1,500. Why, I wonder, isn’t there a machine-made dozuki that sells for about $35 – the cost of a de- cent crosscutting dozuki? Well, I don’t have the answer yet, but the two new rip-tooth dozukis on the market are considerably less expensive (between $70 and $80). To check the quality, I com- pared them to a premium rip- tooth dozuki that I’m quite fa- miliar with – the Kaneharu rip- ping dozuki, sold by Hiraide America for $182 (see the Sources box for more information). Sure they look like standard dozukis, but these saws have rip teeth.We by Christopher Schwarz compare the Kaneharu (in use) with new saws from Harima-Daizo (left) Comments or questions?

Types of Tap
Types of Tap HAND TAPS ISO 529 These are straight flute general purpose tools which can be used for both machine or hand tapping. They are generally the most economical tool for use on production runs, but are best on materials that produce chips, or where the swarf breaks readily. Where deep holes are to be tapped, in materials which produce stringy swarf, serial taps may be needed, especially for coarse threads. ISO 529 hand taps can be supplied in sets of three; bottom, second and taper leads, or individually. BOTTOM TAPS have a chamfer (lead) of 1–2 threads, the angle of the lead being around 18 degrees per side. They are used to produce threads close to the bottom of blind holes. SECOND TAPS have a lead of 3-5 threads at 8 degrees per side. They are the most popular and can be used for through holes, or blind holes where the thread does not need to go right to the bottom. TAPER TAPS have a lead of 7-10 threads at 5 degrees per side. The taper lead distributes the cutting force over a large area, and the taper shape helps the thread to start. They can therefore be used to start a thread prior to use of second or bottom leads, or for through holes. IMPORTANT NOTE ON TERMINOLOGY! In the U.K. bottom taps are often referred to as ‘plugs’. In North America second taps are often referred to as ‘plugs’! This can easily lead to confusion. To avoid problems when ordering it is best to use the terms bottom, second and taper. -
MITER SAW SAFETY (Reviewed 9/27/2007)
MITER SAW SAFETY (Reviewed 9/27/2007) 1. Tool Use and Care • Use clamps or other practical way to secure and support the work piece to a stable platform. Holding the work by hand or against you body is unstable. It allows for work to shift, causes binding of the tool and loss of control. • Do not force tool. Use correct tool for you application. The correct tool will do the job better and safer at the rate for which it is designed. Do not use the tool for purposes not intended – for example; do not use the miter saw for slicing meat. • Do not use tool if switch does not turn it “ON” or “OFF”. Any tool that cannot be controlled with the switch is dangerous. • Disconnect the plug from the power source before making any adjustments for changing accessories. Such prevention safety measures reduce the risk of starting the tool accidentally. • Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges, are less likely to bind and easier to control. When mounting saw blades be certain that the arrow on the blade matches the direction of the arrow marked on the tool and that the teeth are also pointing in the same direction. • Inspect guards before using. Keep guards in place. Check moving parts for binding or any other condition that may affect the normal operation of safety features of the tool. If damaged, have tool serviced before using the tool. Many accidents are caused by poorly maintained tools. • Do not alter or misuse tool.
