The Wavy Larry- my jig

I’ve had several LJ’s request pics of the jig I made for the wavy Larry board. I’ve snapped a few pics and sent PM’s with bits and pieces of info individually. Mikethetermite asked for some info a few days ago and I decided to bit the bullet and take the time to do it as a blog. Here goes-

On my band saw table I have a sacrificial board- 3/4” plywood squared and framed to the table. The back frame piece unscrews and swings up to put the board on and off the table.


On the surface of the board I draw a reference line where the saw blade teeth cut.

Then measure any distance from the blades side cut to the diameter you want to cut in your wood.
For these pieces I picked a 3” diameter/arc. You can make these larger=less curve or smaller=more curve.

Drive a nail hole at this reference point.

The real jig part of this project is a small board with a 90 deg backstop to hold the wood while rotating through the blade. From the backstop measure 1/2 the width of your stock, and strike a center line. Measure down this line about 1/2” longer than your diameter. I measured mine 3 1/2”. Drive a nail at this reference point.

Place the jig with nail onto the sacrificial board nail hole reference point.


Swing the jig through the blade to cut off excess but not through the backstop.


Whith the jig at about 45 deg in front of the blade, measure from the end of the jig (where the arc was cut) out a distance equal the width of the stock. The stock I used was 1 1/8” so I measured out this distance and drive a nail at this reference point. This will be the set for repeating cuts.


The first cut has the square end on it, so I set it just beyond the reference nail, so when the glued up board can be squared up without making the outer pieces too small. The important thing here is to stack cut your contrasting woods. This gives the exact same cut in both stocks when they woods are alternated the cuts match perfect.


Swing through the blade. I use both hands on the stock, but for taking pictures I needed a hand.


After this cut, slide the pieces forward to the reference post swing and cut, repeat.


I set the pieces in order as they are cut.


Lay the strips side by side.


Take the second cut pieces and swap them for alternating pattern. Then the forth, six…you get the idea. I know there aren’t six here but you will have more for the real deal.


Okay, here comes the wave. Turn the upper row 180 deg.


The rest is gluing. Larry glues up all at once. I am chicken, I glue row by row, using cauls. If needed I run them though the planer to clean the edge surfaces for gluing the rows evenly together. That’s just me.


This is by no means any fancy jig, it’s is quick and simple. It works for me. Hope this answers some of the questions. Wake up…it’s over…..LOL

That was a fine blog and well presented… I may change my jig to yours and make a whole heap of different sizes to do different curves…
You are truly working outside the box… I am so happy for you…You are now the teacher instead of the student… NICE.

Lisa, I’m new to LJ. I’ve been visiting a lot of WW sites, but this jig I have to save. I inherited a band saw but haven’t tried to use it yet. When I get the hang of it, I’ll come back for this.

Thanks for the excellent blog and pictures,
