For some reason I have been doing more jigs than a Irish Folk Festival lately. Maybe it’s because I retired less than two years ago and finally have the time to enhance the capabilities of my shop. Here’s the latest, a push block, The Rip-Snorter:
The center block is fully adjustable. It slides horizontally on two steel 1/4” guide rods. The center block is connected by a single, central threaded insert and locking knob. Tightening the locking knob pulls the central block upward and secures it against the length of the top deck. Using guide rods greatly simplified construction, is friction free, and only serves to keep the center block aligned.
The “dog bone” handle allows the locking knob to pass freely underneath and tighten easily in any position. All 5 insert are 1/4’ 20 TPI.
Popular was used throughout. Dimensions were devined by guess and by golly. The main deck is 3/4” stock, 5 1/2” W x 2 1/2”H x 6” L. The rail side support is 5/16th thick, detachable, but not intended to be sacrificial. For ripping any thinner strips, I use a commercially available ball-bearing jig.
The opposite L support is downward adjustable and stabilizes the push block on stock narrower than 5 1/2” wide. It will accomodate stock up to 2” thick. It is 4” x 6” with a 1 1/2” foot. The foot is connected with inter-locking rabbits to increase gluing surface.
Traction is furnished by strips of an old, 1/4” thick mouse pad, rough side down.
Disclaimer: Any similiarity to anything else on Earth, living or dead, is completely coincidental. The Rip-Snorter is presented for entertainment purposes only. Consult a physician to make sure you are fit to rip or still ripping after 4 hours.
Follow Up Note: I have been using the Rip-Snorter since I built it in Sept. 2012. After months of use, I can endorse it. I love the control it provides of both pieces of ripped wood. I puzzled over the dimensions working from a picture of the commercial version. I got them right. The rods, sliding center block, and single locking knob work exceedingly well. It’s very easy to adjust and lock. I’ll be very interested in any enhancements, post them here!
