How to Use A Pruning Saw

Posted on by

Once you’ve decided you need to make a pruning cut and know that the wood is too thick for the otherwise-preferable use of hand pruners or loppers, it’s time to get out your pruning saw. Pruning saws are your choice for wood about 1.5 inches thick or more and your last resort before the very large stuff that you might only be able to do with a chainsaw. As such, they are used to cut a wide range on the large end of wood thicknesses.

 

Since saws are used on thick, often long wood, their use often comes with more cautions and considerations than pruners and loppers, which are basically strong and specialized scissors. Saws can require significantly more strength and control.

 

This guide covers tips and cautions for the use of saws in pruning you can reach from ground level.

 

Pruning with A Saw, General Technique

Wear sturdy work gloves and possibly safety goggles if you’re in a dense shrub. Choose the exact spot to cut and a healthy cutting angle. As you prune, it may help to consider these steps:

 

  1. Notice nearby wood you want to preserve. Often you will be working in tight-angled crotches or near other branches you do not want to cut. More than any other pruning tool, saws easily slip and can quickly injure wood unintentionally, so note this risk in your mind.

 

  1. Choose a comfortable direction of cut. When possible, choose to cut from a top side to a lower side, so gravity is pulling the saw into the wood. By changing where you stand relative to the plant and the angle of your saw, you can usually make the same cut in many different ways to suit your access and comfort.

 

  1. Reduce limb weight with preliminary cuts. This step is crucial and not anticipated by many gardeners. Thick or long branches have significant weight that will cause a premature break and tear before you can complete a saw cut. This is because your saw cut will reduce the wood holding the limb to a weak, narrow strip. To prevent a tearing wound to the plant, you must tactically remove this weight before even starting your last cut at your chosen spot.

 

  1. Begin your final cut with a starting groove. Without this groove, the saw will want to slip away from your site. Slipping is especially a risk on non-horizontal branches.

 

  1. Begin to cut. Working in the groove to guide your strokes, you can cut at a brisk speed now, straight back and forth, keeping in enough control to not slip and wound nearby wood or yourself. Cutting happens on the pull stroke, so bite into the wood on pulling and push back lightly.

 

  1. Finish the cut. Saw until the branch comes cleanly away from the plant. Occasionally some rough wood will be left at the bottom of your cut, like a splinter beard. To achieve that perfect, baby-smooth cut, you can shave this off with a light stroke of your blade pressed flat against the pruning wound.

 

Other Tips and Cautions For Pruning Saw Use

  1. Work comfortable. Set your stance a little wide and plant firmly. Take long pull strokes when possible and pull with a lean of your body for major cuts or at least your whole arm, not just at the wrist and elbow. Conserving strength makes mistakes less likely and makes you a happier gardener.

 

  1. Keep the blade straight. If the blade flexes, you are applying to much pressure when you push it, or you are not pulling straight. Slow down. Apply pressure only on pulls. Get back to a straight, controlled cut and slowly increase your speed.

 

  1. Working near the ground? When working near the ground with any tool, try to keep the blade from getting into the soil. Sand and pebbles in the soil quickly dull any blade. You’ll have to do this a lot during renovation pruning, which involves making a lot of low cuts into the thick, old wood of prolific shrubs like lilac and beauty bush, for examples.

 

  1. Wear your saw in a holster on your belt. This is safe and handy and makes you feel pretty tough, too. Another approach by some is to use a folding pruning saw that can be carried in the pocket. I like these much less—they flex at the hinge under stress. The hinge also tends to collect sap or grit and rust.

 

  1. Clean your saw out before storing it. Tap the tool on dead wood to release most of the sawdust. Wipe sap and sawdust out of the teeth with clean burlap or other sturdy cloth. Storing tools dirty causes them to corrode and lose edge.

 

Chan Long Enterprise Co., Ltd. specializes in producing hand saws used in PVC plumbing, carpentry, interior decorating, making freight pallets and tree pruning. Blades are manufactured with high-carbon steel, which has been tested to Hardness Rockwell C (HRC) 52 degrees. The saw’s teeth have undergone impulse so that it has a hardness to HRC 63 degrees and thus 3-times the durability of regular saws.

Make Your Rubber Products Crack Proof with Ozone Testing

Posted on by

Rubber is a very useful material that is used in almost all the industries to produce various types of products like tires, seals, gaskets, footwear, household products, industrial material, fasteners, etc. These products are manufactured by processing the natural rubber into vulcanized form. As the natural rubbers are very soft and fragile in nature, they can’t be used for production process of any material whether domestic or industrial. Hence, to make the rubber useful, the process of vulcanization is followed. Vulcanization of the rubbers is the process through which the physical and chemical properties of natural rubber are changed to some extent by adding sufficient amount of sulphur to it. This automatically changes various properties of the Sulphur and makes the rubber hard to use for production purposes. The amount of adding sulphur is not fixed; this depends on the application for which the rubber is needed.

 

After the process of vulcanization, rubber is sent to different industries to proceed for further manufacturing. When the rubber material goes through the rigorous manufacturing process, the strong and high-quality of rubbers products will be obtained that are used for various industrial purposes as well as for domestic purposes. The rubber compounds are used for various crucial applications like aircraft, aerospace, defense equipment, and many more. Hence, the rubber material which is used to manufacture these products must be of topmost quality and utmost grade. This is only possible if proper quality testing techniques should be followed while testing the quality of the rubbers. This can be done with the help of high quality of testing instruments. The testing devices that are used to verify the quality of the rubbers must be of best quality. One of the best testing instruments which are used to check the quality of the rubbers is “Ozone Test Chamber“.

 

The rubber goods frequently face the harsh working conditions that also have the presence of Ozone layer in it. The ozone is a very harsh has that adversely affect the quality of the rubbers and the mechanical properties of the rubbers products. This forces the manufacturers to test the effect of ozone on any rubber product. The ozone chamber is an extremely accurate testing instrument which is used to measure the impact of ozone concentration on various properties of the rubbers. It is a closed cabinet that produces original ozone environment to assess the effects of the ozone on the properties of the rubber compounds accurately.

 

If you are looking for machinery of ozone test, Ektron Tek will be the best choice for you. Their ozone test chambers can provide precise and accurate ozone (OZ) concentration environment for rubber and polymer test. For more details, try to visit the Ozone Test Chambers Expert – Ektron Tek.
