Ground auger - are looking for the benefits in their own hands

Ground auger - worth venturing a job?

Qualitatively made tool allows for a few minutes to make the required hole.Existing designs can not match the specifics of the operations: have insufficient working depth, limited choice and small diameter blades, etc.

existing industrial hand-drill to the earth may be one-piece construction and a fixed-length, and may be partially or completely disassembled, with extension rod and exchangeable cutting nozzles.Sami nozzles are two-blade or screw worm type.To facilitate the work of knives special structural steels of high strength and are equipped with lateral incisors straight.

Cutting parts are also stacked, beginning with the smaller diameter of the blades and ending with larger diameter nozzles.Those.Hand drill ground can have a high versatility through capacity-rod length change of rotary handle with short small sizes for maximum long diameter.

more specialized options are limited to the minimum set of bits (usually three), a fixed rod length and the size of the permanent pens.Of course, the cost of a universal set of dramatically higher than the minimum required set.

Probably, it also becomes the reason why a prudent owner thinks of how to make a drill or improve the already existing device of this kind.Perhaps, for example, such a device will only be used to perform non-standard columnar foundation element and therefore it makes sense to manufacture individually.

How do the drill - we select the components and

tool of great complexity in how to make a homemade earth auger, no.It all depends on the ability to find suitable materials and the availability of the appropriate tools.Of course, it is important to take into account the economic viability, but, as mentioned above, it may be that it is device specific properties will prevail over its cost.

as necessary equipment for work need most common welding machine (something that would have to be welded), an electric drill with a set of drill bits for metal, grinding wheel drive: some elements (depending on the type of manufactured tool tips) need to sharpen on the machine.Of course, the work will need plumbing equipment (minimum volume).

As already mentioned, the drill can be different complete sets.But in the general case it needs to stock.As it is quite suitable smooth reinforcing bar (or pipe) in two meters length.To determine the internal diameter of the pipe, it is necessary to try on an old drill about thirteen millimeters.Prout also to fifteen millimeters in diameter.

The length of the pipe or rod about sixty centimeters will be used as a horizontal rotary knob.For bladed knives, experts recommend to get the old drive from the circular saw several diameters.Blades can also be made from steel sheet of appropriate thickness.In this case it is easier to perform a helical screw shape.

Hand drill to the ground - start collecting device

easiest way in the manufacture of drill tightly welded perpendicular to the horizontal rod handle in the middle of its length.Then you need to sharpen the opposite end.For pipes used an old drill, welded inside the rod sharpened to clench and sandpaper.Island can be given a helical shape.

The main stem must be screwed into the soil and not to hinder, but to help the work of the auger.If you cut exactly to the diameter of the disk conveyers and sharpen one radius on each half, the workers obtained knives.Since the edge of the disc gear, grinding is carried out taking into account the movement along the rear of the saw teeth.

Now each half easiest to weld diametrically at an angle of about one hundred and twenty degrees to the shaft at a distance of about fifteen to twenty centimeters from the tip prepared.This sharpened edge should be less blunt.Thus, the entry angle of the blades in the soil will be thirty degrees (considered optimal).

Welding better pattern, provides such an important in this case, the symmetry, because the drill to drill with broken symmetry arrangement of blades is much harder.

If you repeat these operations with three different diameter disks privarivaya them to stock successive pairs, starting with the minimum diameter, you can get a tool to significantly save effort in the works.For removable screws and handles, stem elongation possible special bushings are used, screw connections, etc.
