Wiring without Solder

ANY constructors nowadays avoid soldering wherever possible, and use in preference screw-dowh terminals for making their wiring connections in the receiving set. There is no doubt that if the surfaces of terminals, and. ‘ef leads, are clean, and if the nuts are serewed really bard down, very satisfactory connections can be made in this way. The chief difficulty. in using milled nuts is that it is not easy to screw them down sufiiciently hard to establish a firm connection which will not loosen.. For this reason it is best when building a set to remove all the milled nuts from the terminiuls of the components to be used, and substitute ordinary hexagon nuts for them. . With the aid of a box spanner these can be serewed hard down on the leads, thus making a firm and permanent connection. Where, however, the set is likely to be subjected to much jarring or shaking, it is as well to take the extra precaution of securing each by means of a lock nut turned hard down upon it.
