HINTS FOR THE HANDY

THINGS WORTH KNOWING To rave breaking or bonding very small twist drills, push a cork over the drill before using it. This increases its rigidity to a surprising extent Bushes can often bo extracted from blind holes in timing covers, etc., by filling with oil and hammering a closefitting wooden plunger into the bush. The oil drives out the bush.

To file a plain washer thinner, hammer it on a block of wood to form a recess. The recess will then hold while it is filed.

To unscrew a tight sprocket, wrap a chain round it, hitch the end on the point of a “pinch” bar, place the blade between two teeth, and apply pressure to the chain side of the bar. To extract a tight gudgeon pin or stubborn rings from an aluminium piston, warm the piston with boiling water. It will then expand slightly and release them.

If a valve stem is gripped in the chuck of a breast drill and the drill in a vice, tho valve can be spun with one hand and scraped and polished with the other.

Braking power will be improved and wear on drums and linings reduced if brake drums are kept true and tho surfaces bright and smooth.
