Shop Stool

I made a stool for my shop with a piano style screw height adjustment. The basic plan was published  in Woodsmith #201. I made a few changes which I will describe in the post.

I started on the legs. I changed the leg pattern to make a broader foot and a wider top where it attaches to the hub to increase the strength. I laid all four legs on a single piece of 5/4 red oak - nesting them to reduce waste, and allowing the dado that accepts the hub spline to be cut along one side of the board to be cut simultaneously for all four legs. I then detached the legs from the board one at a time on the bandsaw by just cutting along the outer side of the leg.

I then detached the legs from the board one at a time on the bandsaw.

After detaching a leg I immediately drilled a half 1-1/8 inch hole on the back side of the leg for the foot rest recess, then a 1/4 inch pilot hole was centered in the recess for attachment of the footrest ring. This hole had to be drilled before the finished leg shape could be completed on the bandsaw to allow the hole to drilled at the correct angle.

Splines are used in the stool to attach the legs to the hub and strengthen the segments of the 8 sided footrest blank. I used walnut to provide contrast with the oak. I resawed the walnut to end up with a 5/16 thick spline for both the Hub and the ring. If I make another, I will use a tougher wood - probably brazilian cherry or cocobollo.

Here is what the footrail looks like after the glueup. You can see where the walnut splines stick through the dado cut in each end of the 8 segments, each angled at 22 1/2 degrees. I made the ring and legs thicker than specified in the plans (1 1/4 inches) to allow me to use a thicker spline.

Here is the Hub with the walnut splines already glued in. The Hub is 4 inch x 4 inch - made of laminated red oak. The hole through the middle was drilled before cutting the dados for the splines. I drilled the hole from the top all the way through to ensure that any drift wouldn't adversely affect the two part screw mechanism. Being as careful as I could (checking square on the drill press table), I still ended up with about 1/8 inch of drift from top to bottom. That would have been too great an error if I had tried to drill from each side and meet in the middle.

I made the seat thicker than specified - 1-1/4 instead of 1 inch. Since it would be dished out in the center I wanted a little extra thickness for attachment to the top of the screw plate. I also didn't glue up a square but rather figured the lengths I would need to extend just past the perimeter of a 14 inch circle.

The plans called for making plywood 12 inch plywood rings and then attach veneer to the face of the plywood. Rather than do that, I just used leftover 5/4 oak scraps to construct  a beefier version with a square center large enough to accommodate  the seat plate on the top of the screw mechanism.

I then used my bandsaw circle cutting jig to cut the circles in the seat and sub-ring. I made a square hub that fit inside the sub-ring and the foot rest ring to allow the hollow rings to pivot on the center pin on the jig.

I just my router table with a 1/2" round-over bit to shape the outside edges of the legs and to give the footrest ring its final shape. I finish sanded to 220 grit.

With the base pieces all sanded, I did some assembly. Applying glue to the dados in the legs, and clamping the footrest ring to the mating half round drilled to accept it in the leg. After the glue set up, I used the pilot holes pre-drilled in the legs to drill through the foot-ring and installed 1/4 inch carriage bolts. I had a bit of trouble during assembly with the glue setting up quickly on the Hub splines. If I do it again, I will glue each leg in 4 separate operations.  Allowing an hour of dry time between. I would clamp the leg to be glued in the vise and set the hub spline into the dado. Then use a shaped clamping caul that allows a bar clamp to exert adequate force to hold the joint together.

Next it was time to do the seat sculpting. I used my portable circular saw to cut 1/4 inch deep kerfs in the center of the seat. Always aligning the blade to run through the center of seat, and keeps the rear and front edge of blade at least four inches from the perimeter of the seat. This gave me a depth gauge to go by when using a sweep gouge and mallet to remove the majority of the material. My orbital sander with 60 grit paper removed the gouge marks quickly. I then sanded with 80, 120, and 220 grit discs.

I then applied Watco Danish Oil Finish. I find that the fruitwood shade really brings out the red hues in oak and doesn't affect the walnut color at all.

Now I just need to attach the steel nut flange to hub, and the screw base to the bottom of the seat. The stool has an adjustable height from 24 to 30 inches.

CedarChest For “Little Fish”

Katie asked me to make her a cedar chest for a wedding present. I guess I started something when I made one for her older sister when she got married. I went through my woodworking magazines and gave her of choice of 8 different ones that I found. She picked the one featured in issue #203 of FineWoodWorking - a blanket chest designed by Peter Turner (http://www.petersturner.com/). I changed a few details (wood species, use of a flap stay to protect future grandchildren children, and the finish), but the basic design was left intact.

The legs and rails of the basic chest are joined together with loose tenons. The most time consuming task was to cut the 64 mortises that held the frame together. I had never used these before and was pleasantly surprised in the flexibility it add to the construction process. I made several small layout errors due to the 3 degree angle between the legs and the rails. These were relatively easy to fix by just trimming the loose tenon used in the joint.

To accurately cut the mortises, I made a fence for my router base. I just consisted of hot rolled steel rods that would fit in the holes provided in my router base, an oak fence that I pinned the steel rods to, and a fixed and removable spacer to space the router bit from the edge of the work.

I just consisted of hot rolled steel rods that would fit in the holes provided in my router base, an oak fence that I pinned the steel rods to, a fixed spacer screwed to the fence and a removable spacer that could be attached to the fixed space with three wood screws.

The mortises were all cut in pairs to provide adequate strength for the 1 inch stock used. I built an adjustable fence for my router with a removable space that allowed both mortises to be cut with a single fence setup. I just had to remove the spacer for the second mortise. This ensured that the spacing of the pair of mortises was consistent across all parts, and ensured that the parts joined with the loose tenons would all fit together.

Since the end grain area was so small, a platform to rest the router base on was made by clamping blocks of wood to the side of the stock .

The panels in the chest are the same thickness as the frame pieces. To allow for wood expansion/contraction with humidity changes they must float within the enclosing stiles and rails. The surface of the panel was cut to provide about a 1/8 inch reveal after the panel was inserted between rail and stile or leg. Here the cuts are made on the table saw.

The end panels fit into a dado cut into the wide side of the legs. A block of wood clamped at the end of the groove provides a reference to rest the mortising chisel against to get a square cut.

After dry fitting all the parts for a side to ensure a good fit, glue was applied to the loose tenons and 3 degree clamping cauls were used on the end of the legs to provide a square clamping surface.

To keep the the floating hardwood panels from moving within to rail/stile area (and to keep a consistent reveal), brads were inserted into a hole drilled at each side in the center of the panels, cut off and filed flat. Keep in mind that the maximum wood movement in solid panels occurs across the grain - hence the pins in the center.

After allowing the glue on each side to dry overnight, I used my oscillating sander to create a smooth contour between the joined leg and rail parts.

Now came the big glue-up, joining the end panels and rails to the side panels. I used titebond III for its longer open time. I was still nip and tuck with the number of joints to glued and clamped - lucky I had a helper. I also used a diagonal clamp to pull the frame into square.

Angled cauls kept the clamps from slipping.

Since I had sanded the interior surfaces before glue-up, I could now apply oil to the inside of the chest. I wanted to do this before I inserted the bottom, because the bottom panels were made of aromatic cedar, which would remain unfinished.

This shows the bottom being glued up. The panels were rabbeted and later pinned as described previously for the side panels to allow for wood movement. Bottom was made from 3/4 Inch stock.

A final hand sanding with 320 grit sandpaper prepped the outside for the oil finish.

Since the sides are angled at 3 degrees, the frame of the bottom had to be angled as well. Numerous fitting trials were required to get a snug fit with enough space left below the bottom to allow cleats to be attached on the inside beneath the bottom to keep the bottom in place.

I now made the sliding tray which rides on the rails inset into the inside face of the sides which can be seen on the previous photo. I dovetailed aromatic cedar for the tray and left it unfinished as well. I used 3/4 inch stock for the sides and 1/2 for the bottom. I figured that the area provided by the aromatic cedar in the bottom panel and the siding tray would be enough to keep a strong cedar odor in the chest.

The top was made from Brazilian Cherry (Jatoba), which is very hard and is often used in flooring. I like it because of its color and hardness, which make it dent resistant.  A good feature in a top. The top was made from three boards, edge glued together.  This is what it looked like after Watco Natural Oil was applied.
