BUILDING A CYCLE 95 top tubes in a similar manner to the back fork ends, and the bottom stay-eyes to the long stay tubes. Bridge Tubes.—Fit the short stay tubes to the top bridge in a similar manner, and knock the short bottom- bridge tubes on the bridge lugs. These joints are now ready for brazing, if they are all a good knock-on fit ; but if any of them are loose and likely to move, drill and peg with a piece of wire or brazing peg. Cobbler’s round heel brads make very good brazing pegs (see Figs. 39 and 40). Fitting Head Tubes.—Fit the head tube to the top and bottom head lugs ; drill and peg these. Then fit the top and bottom frame tubes to their respective lugs, drill and peg, and this part is ready for brazing. To keep this part firm whilst being brazed, and to ensure them cooling ^ at the proper angle, the bottom bracket and seat lug may be fitted to the down tube, and this used as a stay whilst the head lugs are being brazed, by fitting temporarily the ends of the top and bottom tubes into the seat lug and bottom bracket respectively. The down or seat tube should, of course, be first cut to Correct length, and before brazing, the top and bottom tubes must be true with each other and out of winding.
