In our kitchen/breakfast space is a big Mission Style chair. My analysis of this chair is that it was home or school shop built in the early 1950’s. It has been in a flooded basement or a flood. It has been over-stressed and broken (before the flood). And repaired by someone-not-the-builder.
After a number of year of our use, some of the joints got loose and it was time to repair.
Nearby you can see the chair after repair. And tools involved.
Forensics: The front lintel had been broken before. I suspect that verticals had splayed enough to allow one of the dowels to break. Pulled back together by the repairer, a scrap of wood was nailed to prevent the splay. Long ago and far away, I learned that nailing oak (other than flooring) was futile. Similarly, the glue blocks in the corners were nailed, maybe more than once as attested by the collection of rusty bent nails in each.

I drilled holes for screws in the corner glue blocks that were loose. Put in screws and re-glued. Glued the dowels in 3 out of 4 corners.
About 3 hours and just a small number of hand tools.
Some “Antique Road Show” host of the future will tell then owner of this one, “Interesting, well made, several repairs, a pretty good chair. But not worth much”.

The 1995 Cutlass Cruiser instrument cluster lamps burned out. Actually, two of them had burned out 3 years ago. At that time, I exchanged the the two burned out lamps from the 0-55 side side of the cluster to the 55-110 side that I hardly ever use. Sometime in March, another bulb went making it impossible to see the speed at night. From the original disassembly, I remembered that it was a pain. Allow about 2 hours. Before beginning, make note of the positions of the dead lamps. It may be difficult to tell failed lamps.
For safety, disconnect the battery to disable the airbag. Avoid the yellow wires associated the airbag sensors and airbag. There are a number of screws (over 20) involved in this, so it may be useful to have piece of corrugated box to hold, organize and note the screw positions. Remove 2 screws from either side of the ALDL connector. This will allow the trim panel to be removed from the car in the next step. Remove 3 screws from the bottom surface and 2 screws from the bottom forward edge of the steering wheel trim panel. Remove and set aside.

Using a putty knife at the inboard end of the outboard air-vent airflow director, gently work each of these out. This will expose a 5/16″ screw head. Two more are located on either side of the open ashtray. and one additional one under the instrument cluster. Remove these screws. The trim panel will be retained by several spring-friction clips. Gently work the trim panel loose and set aside. Figure 2. A flexible trim ring may surround the steering column. Remove it at this time. There are 4 screws under the top surface instrument panel surround and 3 along bottom. Remove these screws and the instrument surround.

There are 4 screws around the instrument cluster. One on the left is hard to reach. The upper screw behind the corner of the radio panel in Figure 2 is the right-hand side. The left-hand one is located simlarly. Two screws are on the lower edge. A wire and clip connect the panel to the steering column collar. The clip will slide off and the instrument cluster can be removed.
Along the top of the back edge there are 6 smaller bulbs. These are type PC74 lamps and illuminate the warnings. There may be an extra in the “spare” slot that you could use in a pinch to replace a warning light. There are 8 PC194 lamps to illuminate the panel. A ninth PC194 lamp is located on the bottom edge to light the transmission selector indicator quadrant. This is the only lamp the dealers computer called out and it called it as a PC195. Dealer price is $15.00. Online price is $2.00. These PC lamps twist out from the flexible printed circuit with a 1/8 counterclockwise turn. Replace any failed lamps. You can test them on the bench with a 9-volt battery and test clips. Avoid wires associated with the airbag..
Carefully re-insert the instrument cluster plugging the PC connectors into the sockets. Start the 3 easy to reach screws. Reconnect the clip to the steering column collar. Use a piece of paper towel to retain the hard-to-reach left-hand screw in the socket and start and tighten left-hand screw. Tighten the remaining screws on the cluster. You may wish to temporarily re-connect the battery to check the lamps at this point. Disconnect the battery before proceeding.
Re-install the instrument surround and tighten the screws.
Press the long trim panel into place. Start all screws. Then tighten all screws.
Re-install the trim around the steering column.
Re-install the trim panel under the steering column.
Re-insert the vent directors. Note that there is a post on the outboard side of the the socket that keys with a slot on the director.
Finally re-install the ALDL socket.
Reconnect the battery.

The mouse wheel on the mouse that came with the Dell 8100 stopped working. Or at least is worked intermittently. If you moved your finger v-e-r-y slowly, you could get scroll to move. But the detent was too stiff for rapid moves. And of course applying more pressure clicked the middle button. I decided that there was slippage and determined to find out why.

Disassembling a mouse is typically one-screw removal. On the Dell mouse, it in the center of the bottom approximately in line with the screw in Figure 1. After removing the screw, separate the shell halves. On this Dell this seemed a bit tricky. There are two tabs on the front of the top shell that insert into pockets in the bottom shell. These pockets can be seen in the nearest part of figure 1. A certain amount of force is require to overcome the springiness and friction. When you separate the top from the bottom, the mouse wheel will probably come loose as it is retained on the top by posts on the top half-shell. It rests in half-journals on the bottom. The skinny end inserts into the detent/switch component on the circuit board. The fat end is over the micro-switch (black component with white bar) which is farther away on the left. The other two micro-switches are for the right and left buttons.
The tire has been rolled off of the hub in Figure 1. What I found was that there was an oily substance between the hub and the tire. I used a piece of tissue, water with a touch of detergent (actually still in the sink from the lunch dishes) to clean the hub and the inside of the tire.

Re-assemble the tire to the hub. Insert the small end of the shaft into the detent/switch as you set the wheel assembly into its bearings. Press the wheel down to verify micro-switch click. Rotate the wheel an verify that the detent works as it turns. Carefully insert the two tabs on the front of the top half-shell into the two pockets that can be seen out-of-focus in Figure 2 beyond the wheel. There is a critical angle and pressure that bends everything just enough. Once the tabs are inserted, lower the top half-shell until it is closed. Re-insert the screw. When re-installing a screw, it is a good idea to rotate in the removal direction (counter-clockwise) until you feel the click of the threads. Then proceed to tighten. This is especially true of self-tapping screws as it is desirable to re-use the original thread, not cut a new one.
Plug the mouse into a computer and test its function.
While I did not disassemble another mouse, a Dynex, I noted that the screw is not visible. If you do not see a screw, probe or remove any label on the bottom to locate a screw. Another possibility is a snap-together arrangement. I suspect the insides will be similar to the pictures of the Dell mouse.

The other week when I pulled the rope on the mower, the rope broke off. Fortunately, the mower started and I just had the rest of the back yard to do. I finished it up, waited for the mower to cool and started the repair job.

My mower is a Yard Machines by MTD 22-inch side-discharge high-wheeler that I bought 15 years ago.

I have replaced the rope at least a couple of times. Here is how I do it.

For safety, disconnect the sparkplug wire from the sparkplug by pulling on the rubber cover.

There are two screws that retain the top cover. The screwdriver is pointing to one of them, the other is on located on the nearer side. Remove the screws with a Phillips screwdriver. Remove the top cover noting the index tab at the rear that engages the fuel tank. Also note the slot where cover allows the pull rope to pass through.

Using a 5/16″ socket, break the 3 hex bolts on the top of fuel tank ring loose (Figure 2). Using a 5/8″ socket, remove the bolt located under the fuel tank (Figure 3). Catch the spacer that is located between the engine block and the tab on the fuel tank. Remove the 3 screws on top. Lift and tilt the fuel tank toward the rear of the mower. It will remain attached by the fuel line.

The metal engine shroud is now exposed. Brush any dirt away from the lower end of the oil filler pipe where it enters the engine block. The oil filler will be loosened but not removed. But if it does fall out, cleaning will prevent dirt from falling into the crankcase.

There are two bolts on the front of the engine (Figure 4) and two bolts (Figure 5) on the back of the engine and the bolt that holds the oil filler. Using a 3/8″ socket, break loose the two front bolts and the two rear bolts. Use a 5/16″ socket to remove the bolt on the oil filler neck. Gently lift the oil filler neck to disengage the peg that holds the oil filler neck to the shroud. Twist oil filler neck slightly to get it out of the way.

Using the 3/8″ socket, remove the 2 screws each at the front and rear. Now lift straight up to remove the shroud and pull-start assemble. The starter will come out of the cup that is on top of the flywheel which engages the ratchet of the pull starter.

Looking at the underside of the shroud, you can see the pulley that the starter rope needs to run around.  A tube inside the rim of the pulley (at approximately 9 o’clock position Figure 7)  is where the starter rope needs to be attached.  There is a small peg located opposite that will assist in winding the starter rope take-up spring.

Make sure the starter rope end is ready.  Measure the new rope against the old and cut to length.  Use a figure-8 knot to hold the rope in the handle.  A new rope will have the nylon melted and may be ready to go.  The melted portion should be no larger than the rope diameter (Figure 6).  If it too large or you have trouble inserting it in the next step, heat the end of the rope with a flame or soldering iron.  Use two pieces of wood to roll it into a pointed shape.  Be Careful: Hot nylon can give you a nasty burn.

As you wind the pulley in a counter-clockwise direction, not that as you begin to feel tension on the spring, the ratchet levers are pushed out of the center area.  These will engage the ridges in the cup that is on top of the flywheel.  Continue winding the pulley 3 turns stopping when the tube is lined up with the hole in the shroud where the starter rope comes through. Push the pointed end of rope through the shroud and through the tube (Figure 8).  Tie a figure-8 knot in the end.  Slowly feed the rope into pulley as it unwinds.  When the spring is relaxed, there should be slightly less rope exposed than it takes to reach the location on the mower handle.  This slight bit of tension keeps the handle from drooping.  If the rope is too long, stretch it out, re-tensioning the spring, draw in a few inches and tie a new knot.

Lower the shroud over the flywheel.  Align the bolt holes, insert and finger tighten  1 bolt front and 1 bolt back.  Verify the operation of starter ratchet.  Release the blade-brake and pull the engine. Verify that the starter rope rewinds.  Insert and finger tighten the remaining bolts on the block.  Carefully, so that it does not pull out, position the peg of the oil-filler neck back in the hole in the shroud.  Insert the bold and tighten.  Tighten the 4 bolts front and rear.

Pass the handle and rope through the mounting ring of the fuel tank. Reposition the fuel tank on top of the shroud.  Insert and finger tighten the 3 bolts on the ring.  Under the fuel tank, insert the long, shouldered bolt through the tab on the fuel tank, then through the spacer (located above the end of the finger in Figure 9) , and finally into the engine block.  Verify the adjustment and tighten all bolts.

Loosen the starter-rope guide on the handle to slip the rope into it.  There should be a slight tension.  Just enough to hold the handle in place.  If the rope is too short, it will put tension on the spring and wear the ratchet.  If too long, the handle will droop and snag shrubbery as you mow.  Verify operation by pulling the engine with the blade brake off and allowing the starter rope to re-wind.   If any of these checks are out, redo the steps above to make the appropriate adjustments. Reconnect the spark plug. Mower is ready to use again.
