Bob Fritz
KITPLANES readers will remember Bob Fritz (1947-2011) for his acclaimed Home Machinist series, but his accomplishments go well beyond that long-running feature. Following a stint in the U.S. Navy, Bob put his degree in mechanical engineering to use and was a tireless advocate for effective and consistent quality control. He brought that discipline to his work for KITPLANES. An avid diver and motorcyclist, Bob's love of flying was a surprise to no one.
The Home Machinist (Part 8)
In his continuing series, author Bob Fritz discusses the ins and outs of threads including how to avoid seizing, types of threads, sizing, drilling holes, using a tap-drill chart, and matching fastener dimensions.
Build Your Skills: Composites (Part 7)
Author Bob Fritz explains how to set up a vacuum-bagging operation in your home shop, using readily available equipment and supplies, which will get you great results on small- to medium-size parts. The object is to mechanically squeeze out excess epoxy for a good-ratio part with maximum weight savings and strength.
Build Your Skills: Composites (Part 6)
In this series installment, author Bob Fritz takes you through the basics of a three-day project you can really use: lightweight fiberglass wheel chocks. The article covers materials, cutting, patterns, foam cutting, eliminating bubbles, and pitfalls to look out for during the build; by Bob Fritz.
The Home Machinist, Part 7
This milling project offers home machinists a great way to get the feel of their equipment and gives them a plug protector for their in-cockpit iPaq as well; by Bob Fritz.
Shop Safety
This article covers what you should have learned in your high school shop class, but didn't, and more. It discusses safety glasses, proper treatment of chisels, gloves, jewelry, shop coats, hand tools, urban myths, safe shoes, hardware, biomechanics, capturing wayward chips, machinery placement in the shop, air-powered tools, cleanup, pneumatic cutting tools, and other common sense advice; by Bob Fritz.
Sport Pilot Airplane
Bob Fritz reviews Sport Pilot Airplane, a new book from Carol and Brian Carpenter, which covers Light Sport Aircraft from selecting an airplane to pilot and aircraft requirements, meteorology, aerodynamics, flying characteristics, transition to new aircraft and FAA paperwork; by Bob Fritz.
Build Your Skill: Composites, Part 5
In this series installment, author Bob Fritz takes you through the basics of building a carbon fiber tank, including measuring, layout, patterns, cutting, epoxy-flox application, sanding, sawing, epoxying and finish work.
Simple Green
Extreme Simple Green - Aircraft is a new product designed to clean your aircraft safely without damaging finishes. Its effective in removing oil and other dirt from the exterior surfaces as well as the interior, and is used by Boeing on its family of airplanes. Its available at specialty stores and aviation supply houses.
The Home Machinist, Part 6
Paying attention to the working environment and maintaining machining tools in tip-top shape can yield a more polished finished product, while also making the fabrication process easier.
A Futuristic Anachronism
Ultimate experimenter Paul Lipps has used his own homebuilt, a Lancair 320, as a test bed for his many innovations, which include reflexed flaps, an ultra-long pitot tube for more accurate readings, a solar-powered fan for the cockpit, a cowl scoop for ultra cooling of the magneto, extremely close clearances between the spinner and the prop, and a one-of-a-kind propeller.
In Case You Missed It
Aero ‘lectrics
Jim Weir takes a look at the performance of a DIY ground-plane antenna versus a factory-built rubber duckie on a handheld GPS receiver.
Buzz Words: Understanding Dihedral Effect
While certified airplanes have to meet Part 23 requirements for positive dihedral, amateur-built airplanes are exempt. Ed Kolano looks into the details of dihedral, and how you can use it to your airborne advantage.
Minimax to the Rescue
It's not easy to find a tug/tow bar assembly substantial enough to handle the job adequately and still be portable enough to be carried aboard.
