Instructions for the manufacture of trimmer grinder at home
We will need a grinder that was spent. Most importantly, she was a working gearbox. Unscrew the cover and then the gearbox itself, remove it along with the rotor. Hold the rotor in a vise and saw off the reducer as close to the plates of the rotor.
Fix the reducer in a Vice and end cutters remove remnants of the winding.
Also usually remove the top of the fragile surface of the shaft at the length.
Hook rotary wheel any chisel or screwdriver, remove it and in place of its planting remove the upper surface of the shaft.
On grinding machines processed the resulting shaft diameter up to 10 mm.
Fasten conveniently reducer in a vise and ground down the shaft threaded with an internal diameter of 8 mm and a length of 15 mm.
Tight preporacuvam on this thread connecting nut M8.
Install the reducer in a vise, that you could drill a hole in the other shaft with a diameter of 9 mm and a depth of 10 mm. It will be a spot for the prop adapter.
Hold the processed shaft in a vise and drilled through the middle in 2 mm from the end of the shaft hole with a diameter of 2 mm. From the prop adapter are also in the seats drilled holes 2 mm in diameter. Mating part with a nail.
Make a mark on the metal tube at a distance of 65 cm from the edge. Find a washer that will put on a thick rod and tight and will be able to pass freely through the tube.
Wound on the rod nut M12, for it put a matched washer and fix the second nut so that the rod is not protruding from it. It will be a pusher for the bearing. Put the rod so that the washer was on a level with the beginning of the tube and primitive electrical tape on the rod at the place where our inflicted label.
Cut from rubber hose 2 rings of 9 mm and one 50 mm long. Make a cut along them. The bearings of the closed type are placed in short-elastic open disposable the middle of the long bands.
Installed a long rubber band with a bearing pusher and press-fitted it into the tube in electrical tape on the rod.
On one side of the tube to drive one washer to a depth of 1 cm, put it on the bearing with the rubber band on them and another washer. Egged on by inside of the tube wall that the washer was unable to pop up.
Two thin rods firmly connected with a connecting nut and insert inside of the tube until the coupling nut abuts the bearing. With the free edge of the tube as well insert the washer, the rubber bearing, another washer, egged on by the phone. Take out the rod at 20 cm and cut it at the edge of the rod drill a hole 2 mm in diameter.
Fasten the sewer stub to the place where stood the casing and connect the rod with the hole on the propeller adapter through the nail.
Placed the cover on the drainage reversal in the opposite direction from the shaft, the rotor, the cap to put a repair coupling, then PVC adapter lower side to the top, he threaded PVC pipe 32 mm and under 25 mm. What would the tube tightly joined each other do they have the incision.
The place where the tube is 32 mm in contact with the tube of 25 mm, clamped tightly by a clamp. On the other side of the metal pipe rod cut at 7 cm from the edge and firmly fix the rod at the 2 nuts against the washer.
Bolt M8 clamping in a vise and drill a through hole with a diameter of 3 mm at a distance of 2 mm from the cap. Put on a bolt two washers and loosely fasten the nut. Between threaded washers in our line, which we mow and tighten the nut. Tightly preporacuvam the bolt line to the gearbox.
In a convenient location on the metal tube fasten the tube clamp with nut and screw it to the handle of the grinder, it is perfect.
It remains only to fix the tip of a metal rod in a drill and you can go to arrange in order around the house.
