Setting Fork Ends.—With the above parts fitted and brazed, the back fork ends should be set before proceeding farther ; and to facilitate handling, the various joints that have been brazed should be filed up, as it is much easier to handle these small parts in the vice now than when the whole frame is fitted together, and there is less likelihood of the tubes getting damaged by excessive pressure in the vice, as there is so much less weight to support. Clean out the fork-end slots to fit nicely on the back spindle without shake, and set the fork ends true, so that when the forks are fitted up. to the bridge the inner faces will .be quite parallel with each other. Unless this is quite true when the frame is finished and the hub nuts are tight- ened up, the spindle will be strained and probably bent, causing the hub bearings to run badly. To test for truth, fix the two forks in place and tighten up the nuts. The ends of the forks should then be of a width equal to the lugs on the bottom bridge, and equally distant from both edges of the wheel rim. Figs. 41 to 43 show the testing of the front bottom tube and the testing of the fork end faces. Fitting Front Part.—The front part of the frame . may now be built up. The bottom bracket and seat lug are fitted to the down tube, and the top and bottom tubes fitted into their respective lugs on the seat lug and bracket. When knocked home, try on the drawing to see that the tube lengths and angles are correct. Then drill and peg ready for brazing. See that the head tube and the down
