Router Plane - #5 Completing the Body & the First Handle

There is just a little bit of work yet be done on the drill press which is to drill the hole for the ¼ -20 insert and install it.  This is where the thumb screw will go that will lock the blade in place.  The dark grey piece is the blade, the gold colored piece is the brass insert and the thumb screw is in line with the brass insert.  More on why this insert is brass rather than steel later.

The body and base that were band sawn out earlier is clamped to the fence on the drill press.  A small drill bit is chucked up and aligned to my center punched mark as shown below.  A pilot hole is drilled through the wood and the steel tube.  When that’s done an intermediate larger drill is used then replaced with the final hole’s drill size.  Then the insert is run in the same way as the others.

Next the body shape is redrawn using the template and cut out using the bandsaw.  After that the disk sander is used to clean up and smooth out the curves.  That’s followed with a pad sander starting with 120 grit paper and ending with 320 grit.

This is what the body looks like right off the bandsaw and when almost done with the sanding.

Last bit of machine work on the body is to go back to the router and put the same chamfer on the bottom outside edge as was done in Post3 Fitting the Tube, Shaping the Base, Glue-up & Layout.  In this photo you can see where the part of the base to the right of the router bit has been chamfered while the rest has yet to be done.  You can also see some scratches left over from the disk sander that still need to be taken out.

Now it’s back to do the final hand finish sanding removing all the disk sander scratches and softening the bodies top edge.  The top photo shows that done and the bottom one is a closer look at the 45-degree bevel on the top edge.


The softening of the bodies top edge is not hard but it is at such a small scale I really need my magnifiers to see what I am doing.


Making the handles are next.  They start out as a roughly 2” square piece of cherry about 3 ½” long.  From there the centers are marked and the piece is put in the lathe with a drive center in the headstock which is on the left and a live center on the right.

A roughing gouge is used to turn the piece round then some layout lines are added based on a revised handle profile.  The revision is based on me holding various plane, file and router handles to see what would work. 

After some time turning and holding the piece as I worked it down the design changed a bit so I went back into SketchUp and made revisions based on what had been turned on the lathe.  Here are the next two versions.  They are the same except for a small difference at the stem.

Those two versions are printed out at full scale and one is glued onto a piece of 5mm underlayment so I can make a template.  A template will let me make multiple handles very nearly identical.  The left photo shows the pattern glued on while the right one shows it after I drilled a 1¾” hole.  That bit is used since it’s the closest one to the 1 13/16” diameter of the actual handle. 

Once some minor fitting of the template to the handle is done I have something that should allow me to make repeatable pieces.  At least that’s the plan.  Later there will be a second template to take care of finishing the top when the tenon on the right end or the top of the handle gets removed.  Right now, I need the tenons on both ends to facilitate the turning process.

Next is drill a hole in the base of the handle.  That’s where a piece of threaded rod will get epoxied in and used to attach the handle to the insert in the body.   Process is to remove the handle, take out the drive center, install the scroll chuck, flip the handle end for end then tighten it in the chuck while using the live center to center the handle on the axis of the lathe. 

With the handle centered and securely held in place the live center is removed and a drill chuck is installed with a 5/16” bit marked with the hole depth.  The lathe is started and the drill run in until the edge of the tape hits the face of the handle.  Here everything is set ready to start drilling.

After the hole is drilled the handle is reversed so the bottom is clamped in the scroll chuck and aligned with the live center in the tail stock.  Now the curve of the top is continued until the tenon is removed.  Here just a tiny piece of the tenon is left.  Once the tenon is removed the piece is sanded up through 400 grit paper.

Last bit of lathe work is to mark the final length and part the handle off.  The photo below shows where the parting tool has just started to break through into the previously drilled hole.  At this point I quit turning and cut the piece off with a fine-toothed hack saw. 

A sharp knife is used to clean the rough splinters up and a hand counter sink completes the handle.  With the master done and patterns created all I have to do is make three more that match up with this one.  Easier said than done.

Below are almost all the things used to make the first handle not including the lathe of course.  😊 At the back are the remaining three blanks ready to be turned.  Right center between the patterns and the drill is the finished first handle.
