A mushroom farm in eastern Pennsylvania mixes hay and manure to create suitable soil for mushroom growth. The soil mixture is then conveyed into bays where it sits and ages for 30 days. After aging, the soil is conveyed out of the bays and transferred onto trays to grow mushrooms. This facility originally used shaft-mount gear reducers on its conveyors. The corrosion caused the plant manager to replace the shaft-mount gear reducers every months.
Easy up, easy down, no problem. It's sometimes a messy process, but always worthwhile. That's not the case with pulleys!
Pulleys are ready to go immediately, without grease of any kind. The loose rope is simply tied off to a cleat , so it can be easily tightened further at anytime. Would you rather choose a more private location? Once you have determined approximately where your clothesline will be located and where you will stand to hang your laundry, consider where your second pulley will be located.
This will be the end of your clothesline. Is there a tree or pole where you can attach a pulley? The higher you can place the second pulley, the better your chances for keeping your laundry out of the dirt. Hanging your clothesline is an easy process, but it does require the proper installation. Determine where you will hang your pulleys. You will have two anchor points to your clothesline. Most pulley clotheslines are less than feet in length. Your first pulley should be just above your head at the location where you will stand and hang laundry.
This is the beginning of your clothesline. The other pulley should be 10 to 20 ft above the ground. Then, angle your long screwdriver in the hook to act as a handle as you twist the screw into the hole. Once your hook is secure in your clothesline supports, you can attach the pulley. This can be an easy process if you already have a clothesline and are replacing the rope.
Tie one end of the new clothesline to your old clothesline, and pull the old clothesline through the pulleys until the new end comes back to you. Stringing a new clothesline may require two people. You can string the line after your pulleys are hung on the hooks, but you may find it easier to run the rope through your pulleys before hanging them. Do you notice that your clothesline sags after use? Cotton clotheslines will stretch as more heavy wet laundry is hung on it.
A clothesline tensioner or tightener uses bearings to help you put tension on your clothesline. It will allow you to tighten your clothesline as the rope begins to stretch with use, even while clothes are still on the line. With the loop end of the tightener facing away from the top of the clothesline, tie one end of the clothesline to the clothesline tightener with a secure knot. Thread the other end through the middle, between the bearings. If you have any trouble threading the clothesline, try wrapping a little bit of duct tape around the end.
Now grip the tightener with one hand and pull the clothesline with the other hand until taut. Your clothesline is full when the tightener stops at the bottom pulley. You will have to tighten the clothesline for the first several uses as it stretches. This is completely normal. The clothesline tightener will make it much easier for one person to do this by themselves.
You can also tighten the clothesline while it is full of wet clothes. Our first clothesline did not have a tensioner. Hubby and I could barely tighten the line with the two of us, especially while clothes were hanging on the line. Purchase pulleys designed for the size line you plan to use. If you use hardware store pulleys, make sure that your 'antenna support rope' can't slip off the pulley wheel and jam between the pulley wheel and housing.
Also make sure your pulleys won't rust. Tie a bunch of knots in each end of the antenna support ropes about 10 feet from each end. Tie the knots to form a large 'clump.
You can release the 'pulley support rope' and pull the pulley to the ground where you can recover both ends of the antenna support line. Up to this point, I have only been talking about trees as antenna supports. You may have other options. A building can be an antenna support, although this is not ideal. Keep your antennas as far away from buildings as possible. Use the building to support only one end of the antenna.
Verticals can take advantage of the proximity effects of a building by using the building as their ground system. One fellow here in town, secured permission to put a trap vertical on the roof of his apartment building.
He has a pretty good signal. Then again, his antenna is over feet in the air and overlooks the water. Metal or wooden masts can be fabricated into excellent antenna supports. Wooden masts up to about 40' can be made with little difficulty. If you plan to put up a tower that has to be guyed, why not use the guy wires as low-band antennas. If you don't want to use guy wires, add an standoff arm to the tower to accommodate wire antennas. The standoff is often a 10 foot pipe, metal or plastic, that is securely attached near the top of the tower.
In most cases, a 10 foot standoff is not necessary. A shorter length will do fine. At the end of the standoff, away from the tower, mount a pulley. You may want to put standoffs out two sides of the tower to accommodate more than one antenna system.
If you have a tower, you might as well take advantage of it, but like a building, it is best to use the tower to support only one end of the antenna. Metallic guy wires may get in the way and interfere with your wire antenna systems. Before selecting an antenna system, you must first find a place to put it.
Trees are frustrating. Methods for getting the support rope up a tree Tie a light string around a rock and toss it over a convenient tree limb. If you are a good fly fisherman, you can lob a line over any limb of choice. A powerful slingshot will put a lightweight fishing sinker and light weight monofilament fishing line about 50 feet up a tree. The real pros are the archers. Forget picking a particular limb, select a tiny branch all the way up in the top of the tree and an archer will lay a line right over the spot and do it the first time.
That's how I put support lines into trees. For years, I used an inexpensive, fiberglass, long bow with cheap arrows. It just took more shots. One Hint If you add extra weight on the front of the arrow, it will drag the monofilament or 'Game Tracker' line out of the tree and down to the ground where you can reach it. The small line goes up first Use light weight monofilament fishing line or something similar as the first line up the tree.
