Veneer Mill

Steam Mill Engine

Labor Day weekend is a big one in Dacusville, SC. Saturday and Sunday were the Dacusville Farm Days. This event has been going on on Labor Day for quite a number of years. A combination of tractor and engine show, crafts, traders, music, and fun. When Phillip and I went last year, we got there too late and missed the veneer mill. While we did see the sawmill operating, Phillip really wanted to see the veneer mill. I checked the on-line schedule and suggested that we get there by mid morning.

We got to the site on Pace Bridge Road right on schedule. The sawmill start was running late and the veneer was scheduled after that. While we were waiting for the mills to run, we got some pictures of the steam mill engine and it’s boiler, a shingle sawmill run from a tractor PTO belt, and more tractors than you can shake a bundle of sticks at.

Both the sawmill and the veneer mill are in separate sheds, each powered by its own large single cylinder diesel engine. The flywheels on the engines are about 6 feet in diameter. Since we got there early, we got to see the diesels started. First a pot-engine drives an air compressor to fill the receiver to 9.5 kg/cm2 (135psi). While this is going on, the starting team opens the cylinder head valve and moves the piston to top-dead-center by using a long metal bar engaged in holes in the flywheel to pull the flywheel around. Next the compression valve is closed and a plug on the cylinder-head is removed. Starting fluid is poured in and the plug replaced. When the air pressure is as required, a valve is opened and the fly is turned by compressed. Once the flywheel is turning, the engine begins to ignite fuel and white smoke pours out gradually becoming clearer as the engine begins to heat up. Once the engine is warmed up, a clutch is engaged to turn the line-shaft. Belts are checked. Everything is good. The engine is brought to operating speed and everything is now moving.

The saw mill consists of a carriage and circular saw. As the log is sawed, the slabs are take off the back and brought to and edge-saw table that makes a rough plank by trimming both edges as the slab is conveyed through the edge-saw. Lumber is taken of the back and stacked.

The veneer mill has a similar diesel engine. The veneer mill itself consists of a cast-iron frame with the log to be worked suspended by two long screw-jacks with face-plates that support and turn the log. the log is scored so that each turn produces two pieces. The jacks are turned by a large 2 m (6 ft) reduction gear. The horizontal veneer knife is held in a heavy cast-iron frame that is moved by a ratchet a little bit at a time into the log. Two men catch the veneers as they come off, roll them and hand them to spectators.

Threshers and threshing machine

After watching sawing and veneer, we had some lunch. We looked for a friend who restores small engines and shows them at shows like this but he had already packed up by the time we were wandering around. After watching the blacksmith and the Parade of Power, we departed. Near the exit, we realized that we had just missed the threshing of about 25 bushels of wheat. Maybe next year.

But the outdoor storage was hard on it and it developed dry rot.  Time for a new body.  I was sure that I had a picture of it but cannot find it.  After I took it apart, I took a picture of the body as it was.

The first step in chair repair is get the chair completely apart. If the chair has failed catastrophically, there may be broken parts along with parts that are still quite tight together. If the chair is just wiggly and loose, many of the joints are probably ready to come apart with the appropriate amount of force. It may be difficult but you must make sure that you have all of the pieces that will or can come loose, loose.

IMPORTANT – as you remove each piece, mark it so that it can be re-assembled in the correct orientation. Make the left of the chair as you sit in it the left. Mark each piece in an inconspicuous spot with Front/Left/Top etc. so that you cannot be confused when it is time to assemble.

CAUTION – watch for modern short cuts that may render your chair difficult or impossible to repair. Staples, pins, repair plates, steel wedges are difficult to remove, damage the wood fibers and are the topic of another future blog entry.

Disassembly proceeds easily at first and then becomes more difficult as the pieces get harder to separate. For large pieces, this can mean working them apart by pulling and wiggling. I find wiggling the piece in a rotating pattern with occasional reversal of direct the most effective. Sometimes rocking side to side is best. Rarely, you may need to wedge some like a stick of wood where the scars will not show and leverage against it to get movement.

Another technique is the tap. Tapping with a rubber mallet can do the trick. Mine is white rubber and does not mark. A hammer, carpenter’s hammer or machinist’s, provide a firmer force. Protect the struck piece with a smooth piece of scrap. The sharp blow of a hard hammer may be more effective at breaking a glue joint. Let inertia work for you. Watch the rebound.

Once you have all of the big pieces apart, try and get the pegs out. Grasp the peg with a pair of slip-joint pliers. See if there is any movement at all. If there is, try to work the peg out its hole. If there is no play and tapping does not loosen it, skip it.

Inspect the pegs. Replace any that are cracked and those that have left a chunk in the hole.

Check the holes. Clean them out with a drill of the appropriate size. Remove any glue left in the hole. Modern glues may not stick to themselves or other glues. Old glue, such as hide glue needs to be renewed so get it out of there.

Clean up the ends of the rungs and the holes in the spindles and rails. Use 60 grit or 40 grit sandpaper to get the glue of and the pegs and pieces smooth. Get everything cleaned up for smooth re-assembly.

Once you have it apart, lay out the parts in the order that you are going to assemble them. Some chairs have to be assembled all 4 corners at once. Others like the one I was working on today can be assembled from front to back or back to front.

The first assembly is a dry assembly. It helps you to do the final assembly correctly and easily.

For my chair, I joined the two front legs with a rung, 4 pegs, and the front piece. Observe the surfaces and the left to right orientation. This I laid flat on the floor. I then added 2 rungs and a side piece on each side.

Separately, I assembled the back. There were 4 back slats, the back seat support, and a rung (which I could not get out). I then put the back onto the front. I noticed as I was doing this a hole that retained a piece of the peg. An I had replaced the peg with a fresh one because it was split. If I had been working with glue, I would not have had time to clean up the hole and get it together before the rest of the chair got too stiff to work with. This is why we do a dry assembly.

Work out how you will put the clamps on to pull everything up tight. You may want bar clamps ( quick-clamps work well) or a rope clamp. I used both.

Take it all apart again and lay it out neatly.

For the final assembly, I used Chair-Loc . I have used this in the past and it is good for about 7 years of daily use on these chairs. The chair I worked on today did not get completely disassembled last time I did repairs and so it has never really been tightened up in 25 years.

Repeat the assembly this time putting Chair-loc in each hole and spreading it around each peg or rung. Press everything together. Clamp it, tap it and get it real snug.

Give it a while to set up, put the seat on and screw in the screws.

The chair is now nice and tight.

I noticed that the cats liked cardboard and corrugated boxes and box lids of a certain size. This is the size that I made the box out of wood. The sides are a little higher than the preferred lids but my wife makes Polar Fleece “puffs” to fill the bottom and the cats seem to like them.

The first box lid that the cats liked was the tray that came in the citrus fruit from Florida. This tray had doubled sides and seemed to be a particular favorite of the cats and so became the model for size and proportion. This one is 16 by 10 1/2 inside. This makes the length 17 1/2 and the width 12 inches.

The basic idea is simple. Four sides and a bottom. The bottom is fairly fixed. It is 1/4 inch plywood. The sides give lots of options.

The first option is the choice of material. Pine, oak, and cedar are good choices. Pine is inexpensive and easy to find and work with. Oak is pricey and pretty. Oak looks good indoors and ages gracefully outdoors. Cedar is rot resistant and can be pretty. Not too expensive but cedar splits easily if the corner screws are over tightened. The height can by the 5 1/2 inch width of 1 by 6 or the 7 1/2 inch width of 1 by 8. And a couple that we have are from 1 by 4. Of course the 1 by is 3/4 inch thick.

The box construction is straight-forward. A rectangle with the long sides (length) overlapping the ends (width). The bottom is set in a groove around the bottom. The groove is 3/8 inch deep in the 3/4 inch thick sides. Cut the plywood about 5/8 inch wider than the width and 7/8 inch shorter than the length.

For the box above, this would be 2 pieces 17 1/2 inches and 2 pieces 10 1/2 inches. The bottom is 16 5/8 by 11 1/8.

NOTE: Follow all general and specific safety instructions for the tools you use.

Cut the side and ends to length. Set the saw blade (or router cutter) height to 3/8 inch above the table and remove the splitter so that you can dado a grove. Be very careful if this leaves the blade unguarded. Check the height with a piece of scrap and adjust it until it is just the right height. If you are using a router, you and your router may be happier and your cutter may last longer if you make several passes increasing the depth until the final depth is reached.

Set the fence so the close edge of the blade is 3/8 from the fence. Carefully make a pass through each piece. If you are using a 1/8 inch saw blade go on to the next step. If you are using a 1/4 inch router cutter, skip the next step.

Reset the fence so that the far edge of the blade is 5/8 from the fence and just a scosch more. Test it with the scrap. Try the plywood bottom for fit in the slot. If it is loose, move the fence closer. If tight, move the fence a bit farther way. When adjusted, make sure that you hold the previously cut edge toward the fence and carefully make a pass through each piece. When you have cut both sides, you may need to clean out the bottom of the groove with a 1/4 inch chisel.
You now have a 1/4 inch groove in all 4 pieces.

Trial fit the sides and ends against the plywood. The plywood should fully close the bottom. The sides should mate up tightly against ends.

Drill and countersink a hole in each side 1 1/4 inch from the bottom and another 1 inch from the top. IMPORTANT: Assemble with brass screws. Steel screws and galvanized screws will leave stains on the wood. Brass screws will turn a pretty verdigris if they do anything.
