Homemade tools: cleaver, concrete mixer, anchor truck

While some tools are complex to manufacture, it is better to purchase in the shops, in the first place - to protect themselves, others, according to forum users, will not be difficult to do himself.

cleaver

Production of various techniques forum member old man with a long tradition. Long before the broad market introduction of foreign products, he did for children snowmobiles, motorcycles, mopeds and mini-car in just a few days off. The inventor proposes to work on wood splitters, which will save you from exhausting manual work for cutting wood with an ax or cleaver.

So how to buy good wood for the bath furnace it was difficult in their area, the old man decided to make the device, seen in one of the foreign sites on their own. Device arranged very simply, a threaded screw, chain drive motor 4 htakny about 9 l / s, 400 cc. cm (before was 200 cubic meters. cm, 6.5 L / s), the transmission of the motorcycle, two bearings. Gas drive is carried out by a pedal - ordinary sticks with rope: Click on it to increase or decrease speed.

The most difficult and unusual detail is the cone with thread. His old man made a turner, first produced a cone, then it sliced ​​resistant (left) thread. Right-hand thread on the lathe machine make the right and the left - from left to right. Since the thread is cut on the cone avoid crease tool, better to make left-hand thread. Her step is automatically installed on the machine and the cutter feed to the height of the thread of the thread is carried out manually. In view of the fact that the cone comes to "no" on the cutting edge can occur hall. Therefore, the beginning of the master thread rhombic patch up a file.

When threaded cone is ready, it is put on the shaft mounted in bearings. On one side a flange is attached with an asterisk (on the rear wheel of the moped or motorcycle).

The cone on the shaft to fix better by a pin (e.g., use M8 bolt). If you do not have time to add a gas engine or stumble on the hard wood in the blade root region, the cone can jam in the wood. In this case, you take out the pin, and a large pipe wrench gut-wrenching cone log. Otherwise you will have to remove the chain, as the motor shaft will not always in the opposite direction.

Between the motor and the shaft of the strut old man Squeegee set of tubes and two nuts, with its help it is pulled chain. On the table, I went to the door of an old rustic planks - it was bolted iron legs. As a support for the shaft can be used on the vehicle cardan support - together with the bearings you buy them cheaply in any auto.

Some of the firewood used for electric power 2-3 kW. Such a single-phase device is not there at all in the economy. The old man recommends the motor from motor cultivator - it is easy to remove, and it does not take much time.

For the manufacture of the cone The old man paid 2000 rubles for the shaft - five hundred. Everything else was found in the garage.

When you work on drilling machines, observe basic safety measures: work without gloves and mittens, without bandages on fingers and palms, with buttoned buttons on jackets and cuffs.

Validating claims that this can chop the firewood and construction debris with nails and staples that make the ax is very difficult. Oh and to work with wood - a pleasure: the work goes quickly, but about the fatigue and back pain the next morning you can forget.

Concrete mixer driven by a drill-mixer

Member Forum blg771 built from concrete mixer drums. First, I put the motor from the washing machine via the pulleys on the pinion from Bendix with it - in homemade handwheel mounted on the barrel. The latter rotates on the front journal "Niva".

Because after a short stint at loading shovels eight SPLG engine stops overheating of the thermal relay, the owner decided to try a two-speed drill 750W - twist has become much it's better. Design remade: Drill-mixer set for 1300 watts.

On photos: drill with paddle and drive circumcised hub.

Used materials

Such a device will not cost: barrel and pin with the hub forumchanin got free, but the barrel can be bought for 500 rubles, and a pin of the hub to recover from the front- or all-wheel drive car.. The trunnion grenades used instead bolt 16: forumchanin welded to the hub with its outer side, wherein the cone washer. If necessary, the barrel can be easily removed together with the flywheel. Drill-mixer - 2150 rubles. The mixer can be removed and used for its intended purpose.

Overturning the owner initially did both purchased and concrete mixers, but the design was very heavy. It had to be redone, but in this version has its drawbacks: it is necessary to use a long lever. blg771 mixer will also remodel: Rising above the axis of rotation, to do a rotation of 360 degrees horizontally, to facilitate frame.

Homemade concrete mixer has the advantage over the purchase-: SPLG can be filled into the fixed drum - no need to keep on weight.

Conclusions Operation

Yield mixture - 60-70 liters. Convenient option was adjustment of turns: it prevented blg771 masonry mortar 22 rev / min, it turned out fine...

The owner poured the foundation for a bath for 2 cubes: about 1.3 concrete cube, the rest - bottles. Loading two buckets, a little scrolled to SPLG went to the bottom (it was inconvenient to pour). Two more buckets, replayed again. Again two buckets, and then included in a regular job (water, cement, etc.). Six buckets SPLG starts easily.

The engine is not heated, but very noisy and a mixer with horizontal drum, if the mixture is very dry, turns with difficulty. The angular velocity of the barrel - 25-28 rev / min. Barrel twists through the flywheel gear ratio 1:16. To use the engine at full power, you can make an additional transfer of 1: 2.

anchor truck

Tri. Dr. E manufactured self-made of drill anchor truck "Rebir" 2 kW (about 4800 rubles.) and the screw approximately 30 cm (6,000 rub.). Planting drill diameter - 25.4 mm at the drill - the third cone without lathe can not do. They did an adapter on the one hand deepen - 25.4 mm (possible 25) on the other - 26 mm. The owner bought a 26 mm drill bit with the third cone, cut off part of the drilling and welded into the adapter.

identified problems

Once all connected and tested, I understood that to keep the device in an upright position does not turn, and drilling below one meter will not lift it, if the clay. Sometimes it spudded so that from a place not move. In addition, the case in the drill - made of plastic. Despite the fact that there is a second metallic pen, when drilling plastic buckles.

alterations

After several unsuccessful drilling samples, it was decided to do a drill press. I had to buy an electric winch for 500 kg (4,000 rbl.). When she lifted the carriage with a screw, drill and clay Area 50h50h5 arched.

For deep drilling Tri. Dr. E use an extension of the conventional steel pipe. To prevent damage to the drill in contact with the stone (once broke the gearbox), adapted pieces of nail 5: in which case, cut it. In this use, the drill needs work - installing the heatsink at thyristor (controlled circulation) nominally it is not there.

operating experience

With anchor truck was built with a pier foundation raft. The soil was a difficult land, then clay, then a lens with a beach sand, clay and sand again, and at the end also blue clay, which could drill only slightly spudded need a pipe for passage of sand water.
