How old are your DualVee guide wheels?
As part of their 60th Anniversary celebration, Bishop-Wisecarver Corp., Pittsburg, Calif., is sponsoring a video contest in search of the oldest running application using DualVee guide wheels and track.

DualVee motion technology was created by Bud Wisecarver in the late 1960s as a way to provide reliable linear motion for applications that were subjected to harsh environments.

“Our company was founded on imagination and ingenuity, so last year we celebrated by searching for the most-creative application using DualVee,” said Pamela Kan, president of Bishop-Wisecarver. “As we wind down from our festivities this year, we want to acknowledge our long history with one of DualVee’s most signature features — long life.”

Submit videos are via e-mail by 1 p.m. EST on June 17, 2011. Judges will review each entry, and on June 30th, the winning video will be announced. The winner receives a four-day, three-night vacation for two to Northern California worth up to $2,000.00, plus airfare. The winner will have a choice to visit San Francisco Bay, Napa Valley, Monterey, or Lake Tahoe. For contest information, rules, and required entry form, please visit

Tool refresher - Part 2
Vise-grips: Generally used after pliers to completely round off bolt heads. If nothing else is available, they can also be used to transfer intense welding heat to the palm of your hand.

Oxyacetylene torch: Used almost entirely for lighting various flammable objects in your shop on fire. Also handy for igniting the grease inside the wheel hub out of which you want to remove a bearing race.

Table saw: A large stationary power tool commonly used to launch wood projectiles for testing wall integrity.

Hydraulic floor jack: Used for lowering an automobile to the ground after you have installed your new brake shoes, trapping the jack handle firmly under the bumper.

Band saw: A large stationary power saw primarily used by most shops to cut good aluminum sheet into smaller pieces that more easily fit into the trash can after you cut on the inside of the line instead of the outside edge.
