Building a Spill Plane

We thought it would be helpful to detail a bit the process for making a spill plane here for those who may have purchased the Plan Kit and would like to learn more about the process.  Begin with a billet of a hard, quarter sawn, close grained wood.  Beech, Cherry,  Birch, and Maple are all good choices.  Avoid soft woods, as they will not hold up well to wear.  Also, open grained woods should be avoided because they are not a uniform hardness throughout.  The billet should squared up and sized at 10″ in length, 2″ high, and 1 3/4″ wide.  Quartered grain runs side to side, with face grain showing on the top and bottom.  The width is 1/8″ wider than finished size to allow for the saw kerf when ripping the left face off.  Once the billet is sized, lay out the screw holes, and drill and countersink for the screws. Be sure to drill 1/8″ deeper than the screws since that will be lost during the ripping operation.  It is also good to countersink the heads far enough below the surface to allow for finish planing of the side when assembled.  We use a template to lay out the holes, but for a single plane, simply using the full size plan as a pattern will work well.

The bottom is then cut using a dado blade to create the fences on each side.  W leave a 3/8″ fence on the right side, and 7/16″ on the left.  The left side is then ripped off using a table saw with the saw fence set at 3/8″.  By removing the side, the mortise becomes much easier to cut.  Cutting the mortise is also done at the table saw, by tilting the blade and using the miter gauge set for the appropriate angles.  This can also be done with a hand saw and layout lines.  Notice in the second photo below that the bed cut is deeper and penetrated into the fence, which allows for the blade to do likewise.  This will be cleaned up with a float after reattaching the face.  Remove the remaining waste using a chisel and floats of rasps, making the surface flush with and parallel to the fence.

Removing the throat waste, using care not to damage the sides.

After the waste is removed, the sides of the body and fence can be dressed with a hand plane, and reattached with the included brass screws.  We recommend pre threading the holes using a steel screw first, to minimize the chance of twisting off the softer brass screws.  Use a wax based lubricant to reduce friction when driving the screws.  Once the side is reattached, the bed needs to be extended into the sides of the plane using a 1/8″ edge float.  It is critical that the cutting edge of the blade extends into the fence on both sides of the sole, and that there is some wiggle room to allow for lateral adjustment of the blade to ensure it is square to the sole.

Next, the wedge needs to be made.  Start with a piece of stock 7/8″ wide and at least 7″ long, (to allow for holding and adjustments) with the quarter sawn grain direction running the same way as the plane body.  Rip the bed side to the angle shown on the print.   the breast side is a compound angle, and needs to be held in some type of fixture to use on a table or band saw.  Shown below is the fixture we use.  (The wedge blank shown should be longer if possible.)  Alternatively, a hand saw and plane can be used.  Regardless of how it is cut out, it will need to be refined with hand planes for an exact fit to the body and blade.

After fitting the wedge, the blade can then be bedded.  This process is accomplished by coating the back if the blade with a dry erase marker, fitting it into the body, and setting the wedge.  Tap the blade down through the plane to loosen the wedge, and remove. Any high spot will show up as places where the marker is rubbed off.   These high spots can be carefully leveled with a bed float or fine rasp.   This is a trial and error process, and should be repeated until there is even rubbing across the iron, especially at the bottom.  A hollow area in the middle is not a concern, but any low spots at the bottom will likely cause chatter in use.  As can be seen in the photo below, there is a high spot in the center that must be leveled out.

Once the bedding is complete, the escapement hole can be drilled.  This hole is parallel to the bed of the plane, and tangent with the front of the blade when installed in the plane.  Layout the location of the hole on the side of the plane body by transferring the bed line across the top and down the side.  Mark the height according to the print.  Make an wooden “blade” the same thickness and taper as the real one, and install this into the plane along with the wedge.   This will ensure there is no damage to the drill that can result from using the steel blade.  Use a drill press with a Forstner drill bit and a method to hold the assembled plane at the correct angle.  Drill through the side of the plane, and as far as possible through the wedge without hitting the far side of the body.  This creates part of the shape needed on the bottom of the wedge.  Notice the wedge is longer than needed, which allows for the drill to be completely buried in the wood to minimize the tendency to lead off.  Also notice the drill is breaking out slightly on the bed side.  This is what you are after.

Mark the bottom of the wedge front where it meets the sole, and remove.  The bottom of the wedge can now be cut away approximately 1/8″ above this line, parallel to the sole of the plane.  A round rasp can then be used to complete the contour left by the drill.   Be sure to leave the leading edge of the wedge sharp where it contacts the blade so shavings do not become entrapped.  the top of the wedge can now be contoured to your liking.

The escapement hole should be funnel shaped on the inside to eliminate places for the spill the snag.  All surfaces need to be smooth.  Test the plane using pine or similar straight grained soft wood, watching for jamming or irregular cutting.  Modify as needed to get a smooth cut and straight, finely curled spills.  Round over the ends of the plane, and clean up all surfaces in preparation for finishing.  We like to use Minwax Antique Oil finish, topped with paste wax. You now have a very unique wood plane;  the only plane where the shavings are what is used!

Spill Plane Plan Kit available now.

For those who wish to make their own spill plane, but lacked both the plans and the ability to manufacture a blade, Red Rose Reproductions now offers a package that supplies everything the user needs to make their own, except for the wood blank.  The full size plans are copies of a hand drawn “C” size (18″x 24″)  print.  This includes the plane body, wedge, and for those interested in making their own, the blade.  Also included are six color photos of various aspects of the plane, and three pages of construction notes intended to help guide the builder through the process. The blade, made of O-1 tool steel, is hardened and sharpened for immediate use.  Nine solid brass screws, used to fasten the left face to the body, round out the kit.  While not step by step instructions, all of the relevant information to build the plane is included.  We suggest intermediate to advanced woodworking skills for this project.

Spill Plane plan kit

For those who wish to order the plans only, this option is available at check out.  Also, the blades are available separately for those who would like to make  additional planes, although we would suggest building one plane the first time to work through the process.  They make a very unique gift, even to those who are not woodworkers. The spills themselves are fun to give away, and make great mantle decorations.
