ELECTROBRUSH

Rust metal, faded over time, brickwork, lost look painted surface… In all these cases is taken sandpaper or a metal brush — and stop! In the direction — is the last day! The lion’s share of tedious work in the clean-up should be given to the mechanism of the electro.

 

Half of the mechanism in front of you, if you have a power drill. Any alteration she doesn’t need. The other half improvised.

 

The way the brush is simple (see figure): an axis — bolt special form planted two steel discs. Landing square neck bolt, so the torque is securely transmitted to the CDs. Between them — spacers, machined from lengths of steel pipe. Each sleeve carries a number of freely located on it “bristles” of elastic steel wire. Wire chopped into lengths of 145-147 mm, and those bent to form a loop under the bushing. External long end of the “bristles” work, internal — only for fixing it in position. When there is a sweep, the inner ends are pressed against the front running sleeves and provide the “stubble” stiffness.

Working tips useful to whittle down perpendicular to the axis of the “bristles,” then the quality of the stripper will be higher.

 

 

 

ELECTROBRUSHES:

 

1 — electric drill Chuck, 2 — axis brush, 3 — nut, 4. — cotter pin, 5 — rear drive, 6 “bristle”, 7 — spacer, 8 — front drive.

 

Going to the tool in such sequence: on the bolt is worn front disc, its opening is inserted in the spacer, and on these column — strung ten “bristles”. Then put back the disk and bolted to the failure of the nut that it can be controlled by the cotter pin. Brush ready to work.
