« Part 1: Plane iron sharpening jig Part 2 of Helpful Jigs series Part 3: Using the lamination jig »

Too cold to spray finish and waiting on blades, so here is a quick blog on a technique to make matching curves for bent laminations.

NOTE: The desired final thickness of your lamination is equal to the diameter of the bottom bearing trim bit you use in this method.


Blanks for the jig. 4 pieces of 3/4” ply to make a 3” deep jig.


Cut and faired 1/4” template is used to get initial curve on a piece of 3/4” ply.


Flush trimmed curve is used as bearing reference for 1” diameter bit. One uncut blank is screwed to the bottom of your initial curve.


Bottom bearing bit routing a channel in one uncut blank. Important that your router stay tight against the curve, as you are cutting the opposite side of your jig at this time.


Plowed out groove is 1” wide. Cut down the center and use the milled edge of the groove as a reference for a flush trim bit.


You now have both sides of your jig with a matching complementary curve.


Screw the remaining rough cut pieces of ply consecutively together, flushing the new plate each time.


Jig ready for strips of wood.

I will cover the surfaces in box tape to keep glue from sticking. CDX is not the best jig making material but I had half a sheet in the shop so I used it.

Good stuff. I’ve never done bent laminations, but I’ve got some coming up this year.

This is for Flair Woodworks shop stool build off. Just a little pre-work. I will be posting the entire process on my FB page, https://www.facebook.com/efcabineture , on the day of the build off, Jan 25.
