The engraving is the most fascinating occupation capable to present joy of creativity to any person. Today the market offers the most various equipment for engraving – from amateur mechanical engravers to professional laser. The compact engraver of the Chinese production it is possible to buy for only several hundreds of rubles. However those who we will gain desire to do by all the hands can make without effort the most ordinary mechanical engraver.
It is required to you
- Flexible shaft with set of mills from the dental drill, the electric motor of small power, set of the metalwork tool, tool-grinding the machine, electric drill.
Instruction
1. Pick up all components necessary for production of the engraver. In overall view the scheme of the engraver looks as follows: the electric motor – pulleys – flexible shaft. From the electric motor the rotation is transmitted through pulleys with rubber passika on flexible shaft on which end engraving mills are fixed. It is not difficult to pick up the electric motor, any model working from alternating current of 220 volts – from the fan, the tape recorder, the electrorazor, etc. approaches. Very well engines from sewing machines as they are equipped with rheostat for change of rotational speed approach. The possibility of the choice of flexible shaft is quite limited. The basic and the most optimal variant is the flexible shaft from the dental drill. It has tightening grip for mills thanks to what need to think out way of fastening of mills most disappears. Pulleys can be taken from old tape recorders which are stored in storerooms or on attics of the majority of houses. Together with them it is necessary to take away also passik.
2. Manufacture the bed for fastening of all components of the device. Its design represents the basis (sheet of textolite or thick plywood) with the bracket established on it for fastening of flexible shaft. It is the most convenient to make bracket in the form of the collar crowning the rack fixed on the basis of.
3. Fix the engine and flexible shaft on the bed. The engine fastens directly to the basis, the flexible shaft is inserted into bracket collar. After tightening of nut the collar has to clasp densely and reliably fix the end of flexible shaft.
4. Connect pulleys to shafts of the engine and flexible shaft. At discrepancy of diameters of shafts with landing openings of pulleys it is necessary to use reducing sleeves. Pulleys on shafts fasten by means of zasverlivaniye of their flanges together with shafts and the subsequent rodding. It is possible to apply to ensuring density of landing of pulleys to shafts also epoxy resin. Use of pulleys is useful that they allow to increase mill rotational speed. Than pine forest rotational speed is higher, especially the engraving turns out qualitative. However also direct connection of shaft of the engine with flexible shaft is possible – without use of pulleys.
5. In need of direct connection of shaft of the engine with flexible shaft carry out it by means of piece of rubber hose which ends are put on the connected shafts. The hose in this case plays coupling role. The only requirement to it is in that it densely clasped the ends of shafts, excepting their slipping.
