Customer Projects: A BB-firing Gatling Gun Model by Michael Gegere
A ruler shows the small size of the barrel mechanism—only about 10" long.
This beautifully finished Gatling gun fires #7-1/2 birdshot about 20 feet. The carriage features hand made wooden wheels and details like a screw elevation adjustment. The vertical gravity feed clip holds 60 shots. The wooden display base is about 14" long. A Plexiglas cover keeps dust off the display.
The Shop Secrets—Measuring video is now available on DVD.
P/N 5329-DVD Shop Secrets video now on DVD—The Shop Secrets video by Mike Rehmus covers how to use and maintain measuring tools in your metalworking shop. Up until now it has only been available in VHS tape format. Mike has now released the 112-minute video on DVD. We are now out of the VHS versions and they will no longer be offered. If you’ve been waiting for it to come out on DVD, now is your chance. Order P/N 5329-DVD ($40.00—same as before). This video makes a great companion to Mike’s recently released video on set-up and use of the Sherline lathe (P/N 5335, $49.95).
Shop Tip of the Month—4-jaw Chuck Spacer Plate by Allan Marconett
The chuck plate with slots for the chuck jaws. Photo 2 shows the parts being held, and Photo 3 shows some finished parts.
Problem: How do you keep small parts flat, parallel to the chuck surface and not let them fall into the chuck while you tighten the jaws? Here’s a good way to solve those problems from Allan Marconett. (See also www.sherline.com/tip42.htm for more photos.)
Cut a plate out of aluminum to allow small parts to be machined while being held in the Sherline 4-jaw chuck. The example photos show a brass slide valve being machined, with packing all around. The plate gives a flat support, the slots allow the jaws to get in close to the stock being machined. Holes can be drilled or machined through the plate, as it is expendable.
The plate is a simple 2" x 2" square of 1/8" thick aluminum plate (could be round!) that may be cut out with a bandsaw. Notches in the support plate keep small parts from falling into the chuck during setup. It gives a smooth, parallel support for small parts held in the chuck. Size is unimportant, and thickness can be changed to fit needs. 0.350" slots are cut in from three sides to clear the width of a jaw. Allan leaves about a 5/8" square of material in the center. You can leave less if needed for smaller parts. A three-jaw version could also be made with slots 120° apart.

• The special Saturday open house held
June 28th was a success, bringing in a number of people who could
not visit the museum during our regular weekday hours. A number of senior
groups from local retirement communities have also discovered the museum and
are bringing group tours filled with retired craftsmen. The recent addition of
51 internal combustion engine models from the collection of Paul and Paula
Knapp has been a large part of the attraction for visitors.
• An electric stair lift chair has been added to the museum so that handicapped visitors can now have access to the major displays on the second floor.
