- INCRA LAUNCHES FREE PROJECT PLANS -
If you’ve taken a look at our new Build-It System’s page, you’ve noticed quite a few free downloadable jig and
fixture plans. These plans make it easy for the first time user of the Build It System’s modular components to
quickly assemble some pretty important jigs for the shop. From segmented ring jigs, to crosscut boxes, tenoning
jigs, coping sleds and more, these plans also provide some interesting food for thought and can be used to begin the groundwork for designing your own custom fixtures for the cutting requirements in your shop.


The New Build-It System’s modular components take all of the frustration out of the process. The Build It System’s Panels are pre-drilled, countersunk and counter bored to accept all of the necessary components for just about any jig or fixture you can imagine. INCRA’s expandable Miter Slider guide runners can be attached without making a single mark or drilling any holes. Then, Build It T-Slot Panel Connectors can be added to permit easy expansion of the platform size and to provide T-slots to make adding and adjusting your jigs critical components like fences and hold downs a snap. And, if one of your Build-It System Jigs looses its usefulness in your shop, you can reuse and reconfigure the components quickly for your next jig design.
While we all know the safety and efficiency benefits of jigs and fixtures, it is all too often that we put off building a jig simply because of the time required to design and build the sliding platform. Before the Build-It System that meant beginning with a blank piece of sheet stock carefully measured and marked for a series of neatly aligned and properly placed holes required to mount the guide runners. Then, another set of holes for mounting the jig components (fences, t-tracks, hold down fixtures), followed by some anxious assembly and hopeful alignments, which don’t always work out just like you planned. Before you know it you’ve spent your entire day in the shop working on the jig instead of your project.


I’ve personally enjoyed making and using each of the jigs shown in the plans, some of which were assembled and in use in less than 30 minutes. And for those of you who have seen some of the small pieces I cut for my puzzle boxes, I can assure you that jigs like these are the ONLY way to safely and accurately reproduce the results. Thanks to the Build It System, I’m looking forward to taking advantage of a little more time in my shop to work on the projects that I enjoy most. The free jig plans you’ll see included on the Build-It System’s page are just the beginning of a concerted effort at INCRA to provide a place for you to gather more than product information. Let’s face it, were it not for woodworking projects, who would need tools in the first place. So you can look forward to even more new Build It System Jig Plans in the future and beginning this week we have also added a NEW section to our website devoted to Woodworking Project Plans.

Our first couple of plans provide a bit of a bonus, in that each plan includes a beautifully designed project AND plans for a Build-It System Jig. Each of these two plans, submitted by Lloyd Johnson, revolves around a decorative technique known as mitered lamination. This technique produces some of the most striking visual patterns I have seen in a woodworking project and is really quite easy to add to a variety of project types. In a nutshell, the technique revolves around crosscutting a series of short pieces from a strip lamination with the miter angle set to some number less than 90 degrees. Every other one of the resulting pieces is then flipped over and the parts are glued back together. This first pattern is referred to as a first generation lamination. The process can then be repeated with the resulting glue up to create second or even third generation laminations with ever more intricate patterns.
The use of mitered laminations in woodworking is a relatively new technique first introduced in Clarence Rannefeld’s book, Laminated Designs in Wood, published in 1998. Mr. Rannefeld’s descriptions, while very detailed, wonderfully illustrated and quite accurate, included many mathematical formulas to allow the craftsman to predict the results of the amazing patterns that could be created. He also included plans for a fairly complex jig that looked like it would have required several days to produce. These formulas, along with the complicated jig, scared away many who might otherwise have tried the technique. What we needed was a little interpretation, and this is where Lloyd Johnson comes in.
Lloyd created a computer software program called “Lamination PRO” that provides an easy to use method for designing and visualizing the infinite variety of decorative patterns that can be created using the mitered lamination technique. That means NO MATH. I found the program quite intuitive with a simple set of buttons to set the program in motion. You can choose the wood types from a drop down menu that includes everything from the exotics like Bloodwood and Ebony to every type of figured Maple.

The program lets you choose the angle and width of the crosscuts as well as your blade kerf and the graphics make it as much fun to create the patterns on your screen as it is to create them in your shop. You can learn more about this exciting program at: www.woodturnerpro.com/software/lamPro.html
You’ll surely enjoy Lloyd’s Cutting
Board project
. It allows 3 design
variations that all begin with the same strip lamination. I particularly enjoyed Lloyd’s simple Build-It System jig design that features a unique “incremental positioning” element for locating each of the crosscuts. I think this project is
the perfect entry point for someone
wanting to learn more about this
technique. It uses very little stock,
insures a high level of success and is certainly going to be a desirable item in your circle of friends.

The Sweetheart Clock project takes the mitered lamination technique to the next level by cutting the final lamination into radial segments that are glued to form a circular disc. The final decorative element details can be either turned or cut using a circle-cutting jig at your band saw. No doubt the “timeless” beauty of this project will make the additional challenges worth it.

While you don’t need Lloyd’s program to try out the mitered lamination technique in building any of the two projects on our project page, you can download a free 30-day trial version and try it out for yourself. Lloyd’s site also includes a variety of plans and additional software for designing and visualizing segmented turnings. You can visit his website at www.woodturnerpro.com.

If you or anyone you know has a jig or fixture design that would be a candidate for the Build It System components or if you have a unique project that features the use of any of the Incra line of Precision Woodworking Tools send a photo to perry@incra.com and lets see if we can add your name to the list of contributing craftsmen that are appearing in our Gallery, Projects or Build It System pages at www.INCRA.com.
Keep us posted on your unique shop layout or any special project you may be working on by dropping me an email: perry@incra.com.
