Porch Swing/Glider - #9 Finishing End Rails, End Stiles & Base Stretchers

Finishing up the top and bottom rails consists of ripping them to final height using the table saw and cutting to length with the chop saw.  Next is rounding the ends which after layout gets rough cut on the bandsaw followed by cleanup on the 12” disk sander.

After doing cleanup on the disk sander a pad sander is used to smooth the curve and ease the transition to the flat areas at the end.  Below is a photo showing what the curve looks like at each of the steps.

Routing a radius on the ends and the rounded edge is next.  The bottom rail may get some more rounding after the foot pads are added.  I will have to wait until they go on to make that decision.

After that the screw holes, any knots or other flaws get filled with plastic wood.  When it dries all the surfaces get sanded smooth.  This is what the rails look like at that point.

Up next are the four vertical stiles that connect the end panel upper and lower rails together.  The top drawing below shows where they go.  The bottom drawing shows the tenons that will get cut on the top and bottom to go into the mortises in the rails.  There will also be a through mortise cut for the cross rail.

The tenons get cut with a stacked dado.  The top photo shows the first cut which is the tenon height.  It is just a smidge shorter than the mortise is tall so I have a little wiggle and adjustment room when it comes time to glue up.  The bottom photo shows the face being cut.  In this case they are cut just a couple hundredths wider than the mortise since there is maybe a hundredth of an inch variation in the width of the mortise.  This gives me a little material to fine tune each tenon so I get a snug fit.

The fitting is done with a couple of hand planes.  The one on the left is used to cut a small bevel on the leading end of the tenon to make starting it in the mortise easier.  The right plane is a shoulder plane that does the real fitting.  It is different in that the blade is the same width as the body.  This lets me get right into the corner when using it keeping a nice crisp inside corner.  Since the tenon thickness is cut close the last little fitting does not take long to get a nice snug fit.

Once all the tenons are fitted a test fit is done shown in the top photo to see if there were any problems and fortunately weren’t any.  If you have seen many of my posts you know I am a big believer in making notes to myself on the parts either in chalk or pencil.  The bottom photo shows my notes and numbering for the tenons so there was no question about size or which tenon got fitted in which mortise.

When I went out the next morning to cut the through mortises in the stiles, I had a little surprise and not a good one.  Overnight a little pitch had drained out of the piece.  Most of it scraped off easily enough but there was a bit of residue left.  I don’t know for sure how that will impact the finish stain but it’s probably not good.  For now, it will be left upright to see if it’s all done or if more drains out.

Cutting the mortises will be done with the mortising machine.  The left photo shows mortiser with one of the stiles clamped in place and a stop at the right set so all the other pieces can be aligned at the same position.  The top right photo shows where the mortise will be cut, the mortising chisel and the steel square used to align the right edge of the chisel to the cut line.  With this end located a stop is set.  The same procedure is used to align the back side of the chisel with the back cut line and the left side of the chisel to the left end of the mortise, setting a stop for it too.  The bottom right photo shows the first hole drilled.

The sequence of drilling is to do opposite ends then space out holes leaving less than the width of the chisel.  Full width holes are drilled so the forces on all sides of the chisel are the same.  If one side is open then there is a possibility of the chisel drifting to that side and not drilling a plumb hole.  Last, the in-between webs are drilled out.  Uneven side pressure is not a problem as both sides are open.

After all four stiles are cut with the above setup next is to cut the second row.  The same alignment process as before is used to set the front face of the chisel but the side to side and location of the stile is already set from the previous setup.  The cutting process is the same as the first row.  In the bottom right photo, the remaining thin center strip has been cut away.  It’s easy as a cut on each end frees the center section seen leaning up against the back fence.

The next pieces are the two base stretchers.  The drawing below shows where they go.  In general, they are made the same way as the stiles that go in the base ends with a tenon on each end.  Main difference is they are a lot longer and a bit more awkward to swing around.  In the bottom photo the tenons are being cut and after that the long edges get softened with a routed rounded edge.

One difference from the stiles is the stretchers don’t have a mortise cut in them but they do have a notch for a runner attached to the swing.  Here in the top photo, it is being cut with the stack dado.  The bottom is a close view.  The blue tape is there to reduce the splintering as the blade exits the stretcher and the clamp helps keep the long piece in place.

Last since the tenons extend through the stiles they need to have the exposed ends rounded using the router.  Because they are so long to route them, I need to stand on a step stool to get to them.
