STEP BY STEP
The jig can be made to suit the length of carriages that you’ll be working on, although exact dimensions are a matter of personal preference. Here, a length of ‘bullnose’ timber moulding has been employed. Align the part carefully, making use of the window apertures for the clamp’s screws to distribute the pressure evenly. Cut and fix a length of plastic or metal strip to act as a locating fence for subsequent sides. Tighten the clamp and, with a long steel rule, exert firm, even pressure over the whole length of the brass side, pressing it against the shaped timber. Remove the side from the clamp and check the profile against the carriage ends. Re-clamp and re-shape if necessary until a close match is achieved.
