In April 2024, I attended Tremendous Woodworking New England on the Connecticut Valley Faculty of Woodworking. On the occasion, I sat in on Andrew Hunter’s Japanese handplane presentation. Andrew is a devotee of Japanese instruments and referred to as out a number of shortcomings of Western planes. His major level (as I took it) was {that a} Japanese airplane’s cutter sits at roughly 2/3 of the best way BACK from the entrance of the airplane, giving it a really secure lead into the reduce. A Western airplane’s cutter sits roughly ¼ of the best way from the FRONT of the airplane, and beginning a reduce requires pushing ahead on the heavy rear portion of the airplane whereas just one/4 of the airplane is balanced on the floor of the workpiece. So as to add one other variable, it’s that entrance 1/4 of the airplane that’s most vulnerable to put on.
Later we chatted about how such modifications would possibly come to move. Being a device maker, I had concepts. Alongside the best way, Andrew stated “You need to make that.” Ultimately, I made a decision to present it a go. Due to Tremendous Woodworking for posting movies of the presentation. It made it straightforward to return and take notes. The entire occasion was superior.
The modifications included transferring the cutter to the rear of the airplane, bedding the blade at 39° as a substitute of 45°, and sharpening at 28°. My proof of idea began with a $3 storage sale discover; a Stanley #24 burner (transitional), purchased only for the iron. The #24’s metallic elements can be the idea for the brand new airplane. I sharpened and tuned it to verify it could take a shaving, then tore it down. I used the donor physique as a sample to chop the advanced mortise for the re-mount on a ramped airplane physique in Douglas fir and the outcomes have been wonderful. It took tremendous high quality shavings and received a glassy floor on white pine and cherry. I’ve to suggest in opposition to utilizing doug-fir for a hand airplane primarily based on the splinter danger!
What follows is a step-by-step information to constructing Stan Li, the Asian Fusion Handplane.
I “received” a calmly restored Stanley # 27½ from a web-based public sale website for about $20. The “restoration” of the physique appeared to be performed with a belt sander, nevertheless it was going into the fireplace anyway. Once more, I sharpened & tuned it to verify the heart of my construct labored of their authentic type. Don’t skip this! You’ll want a pointy blade in a while, and discovering out it really works gives peace of thoughts for the trouble you’re about to place in.
Tear down your donor airplane, taking notes and photographs as you go. Take note of the place of the body relative to the mortise and hint it on the physique earlier than you unscrew it, it’s going to assist later. You’ll be duplicating the mortise from the donor airplane with one change; a tighter throat. My 27 ½ had a forty five° mattress and a ten° throat, with a 15° put on on the base. The mattress and throat projected to intersect simply above the only real, with the damage serving to open up the mouth (fig. 1 beneath). The damage and mouth can be opened slowly as soon as the iron may be set within the physique as a information.
The mortise additionally had a notch to simply accept the casting’s extension for the cap screw. ¾ in. again from the mattress, there have been 2 brass threaded inserts for the frog screws. That is one place the place Stanley determined to not reinvent the wheel. The inserts and screws have been a loose-fitting 1/4-20. Three screws have been holding the body to the physique—one behind the tote, one by the knob, and one simply in entrance of the mouth mortise. The donor physique got here in at 15 in. x 3 in. x 1-3/4 in.
Begin with a clean that’s the correct width, however thicker than the Donor. My 3-1/2 x 3-1/2 x 18 in. Q-sawn onerous maple block was bought as a 36” baseball bat turning clean on ebay from MoBat Firm. They promote as 3 in. x 3 in., however they arrive in heavy. I dressed it down to three x 2-1/4 in., with the quarter-sawn grain strains working throughout the 3-in. measurement on the top of the clean so as to hold modifications in thickness to a minimal. I let it sit within the store for a number of weeks and it stayed straight and true.
Minimize your Iron body down as a lot as you dare—I misplaced about 5 in. I deleted the rear part for the tote, then drilled a gap and filed a flat to make use of the knob on the rear. For now, drill a 1/8-in. gap that may change into a pilot gap for the knob screw. Do that on the drill press for correct placement. On the entrance, I eliminated the seat for the entrance knob. There’s a screw gap that remained simply in entrance of the body opening that I’ll use for last meeting.
The important measurement to get the brand new airplane to operate is the thickness of the physique at 90° to the body on the mouth as measured from the donor airplane. The brand new block is thicker as a result of we’ll reduce a 6° ramp on the rear of the airplane to decrease our mattress angle to 39°. (The tote received’t be cozy at this angle) Minimize the ramp utilizing a tapering approach on the jointer. Make a check taper utilizing some scrap and rely your passes. As you method 6° decelerate and go 1 move at a time. I took 9 passes, measured utilizing a Wixey digital angle gauge and landed at 6.01°. A last move with out the backstop cleaned up the small snipe on the entrance with out altering the ramp angle.
After figuring out the place of the body on the ramp and slicing the mortise, you’ll use mild passes on the jointer to mill the only real of the airplane “up” to the mouth at 1 3/4 in. beneath the ramp floor. Resist the temptation to slip the body right down to the place you received’t must mill the only real. Tearing out the only real on the mouth is a far worse and extra possible consequence. Don’t ask me how I do know this. The jointer additionally opens the mouth barely with every move because the mattress and the damage develop additional aside and it’s a managed means of tuning the mouth.
Place the cut-down body on the ramp and tape it in place. Utilizing the donor physique as a sample lay out your mortise on the facet of the ramp and ensure you have sufficient meat beneath the place the mouth will land. When you’re positive, screw it in place. Use undersized or quick screws now so that you’ll have stable meat later for everlasting mounting. Hint the body on the ramp and take away it, then use the donor physique as a information to put out your mortise for the mattress and throat. Don’t fear concerning the put on but. Keep in mind to make use of solely the ramp as a reference floor.
Begin by chopping out “inside” the mortise leaving about 1/8 in. in all instructions to keep away from splitting in the course of the fast heavy chopping. You’ll be able to drill out waste to the extent that you’re snug and even use a hole chisel mortiser in case you are so geared up. Decelerate and method your structure strains. Keep contained in the strains for now (depart the strains simply seen on the floor). Cleanup and refinement will get you there later… keep away from going over.
Refine the mattress with chisels. As you get deeper put a stable straightedge throughout the mortise to reference a combo sq. and pare right down to 45°. Widen the mattress till your airplane iron suits with about 1/16” to both facet… it ought to be near your structure strains. Don’t attempt to good the Bbed but, transfer on to the perimeters and the throat. Your depth at this level ought to be in need of the complete thickness of your donor physique. The added depth will come from extending the mattress to satisfy the damage.
Take a small, flat block of one thing (I used aluminum) and refine floor on one thing flat like your tablesaw with sandpaper on it. I drilled a gap for my fingser to grip into. Soiled up the sanded floor with a pencil and rub it on the mattress. The soiled elements of the mattress are excessive spots that should be pared away. Take away the pencil marks with a chisel, rub once more, take away the excessive spots, and repeat till you get a uniform soiled floor if you rub the Mattress, which is now flat. Double-check that you just’re nonetheless at 45°, get again to it in case you’re not.
As soon as the Throat and the Mattress are assembly on the backside, set up a line for the Put on. Use a slicing or wheel gauge to hit the purpose of the Put on on the donor block. Switch the mark firmly onto the throat of the brand new physique. Cowl the within of the throat with inexperienced painters’ tape and mark it once more, then peel the tape beneath the mark. This would be the higher touchdown of the Put on. Switch the mark up and across the physique till you hit your structure strains on the perimeters. Measure the angle of the damage on the donor and lay it out on the brand new airplane. Mark the road absolutely throughout the facet of the airplane so you should use it as a visible reference for holding your chisel.
Clamp the physique to your benchtop. You continue to have meat beneath the place you’ll be chopping to so there’s no want to fret about blowing by to your bench. Start chopping the Put on right down to the Mattress, then prolong the Mattress to the Put on and repeat till the Put on angle is right and the mattress has been prolonged to satisfy it. You need to nonetheless be effectively above the underside of the airplane physique.
To put out the notch for the cap screw tongue rigorously lay a strip of inexperienced tape on the donor physique proper as much as the road of the Mattress. Flap the ends for simple peeling and safe it across the edges to the perimeters. Mark the corners/ edges with a pencil. Rub a pencil on some scrap and get a fingertip filthy. Rub the finger on the taped floor to get the positions of the notch and any screw holes. Take the tape off rigorously and switch it to the brand new airplane physique. Centerpunch the screw holes and chop the notch proper by the tape.
On the drill press, stage the ramp relative to the quill and drill small pilot holes in your punch marks. In case your frog was held to your donor physique with wooden screws observe up with the suitable pilot gap for these screws. Measure how a lot your screws will prolong into the physique, particularly on the rear of the airplane. Not all of that meat can be there after you mill the only real again as much as open the mouth. In my case, I wanted so as to add threaded inserts for machine screws. I used a 3/8” forstner bit and set the depth to simply beneath the floor of the ramp. I examined the drill and insert on scrap, near an edge and finish to verify I used to be not going to separate something. The enjoyable a part of woodworking is that there’s at all times a last-second alternative to damage one thing you will have a bunch of effort and time in! The inserts have been seated with a hex bolt and a hammer. Now it’s time to suit the body & frog.
Utilizing quick screws to depart a little bit of undisturbed meat within the physique block for last meeting, mount the body to the ramp. If all went effectively the surface tracing ought to be useless on. Add the frog and line it up with the Mattress. Drop in your iron meeting. It ought to land at a degree the place you may nearly run the iron advance up and into the chipbreaker slot. Take out the iron and head to the jointer.
Set the jointer for the lightest reduce potential and go to work. Maintain the physique as much as the sunshine to see if you’re getting shut. My jointer has a segmented cutter and sadly leaves slight scallops so I alternate feed instructions between passes. On the ultimate passes, feed the airplane into the cutter so it received’t tear out the forefront of the mattress. When the mouth turns into translucent you might be shut. Get the mouth open and re-fit the iron and lever cap. The mouth can be too tight. Take away the cutter and take one other move or two… re-fit, repeat. If you assume you’re there attempt to take a shaving.
My first shaving choked on the mouth so I went again to the jointer for an additional move. Second and third have been the identical. My fourth shaving got here off completely straight, an indicator that the chipbreaker was not participating the shaving, the reduce was additionally a bit dished. The offender was a slight bulge simply behind the mouth the place the iron and lever cap utilized stress. I used a chisel to trim away the bulge with the blade meeting put in. I took one other move, the shaving was good and the planed floor was glassy & stunning. The airplane pushes simply and pulls as effectively. I’ve restricted expertise on the pull facet so I’m wanting ahead to getting it into the palms of somebody like Andrew.
With the operate shut, flip to the ending. Take away the body and clear up the surfaces. I needed to scrape the highest, ramp, and sole to take away jointer marks. I chamfered corners, cleaned up the top grain, and added grip grooves on the perimeters. A lightweight sanding on all however the sole and a wipe of sealcoat completed the job.
