Practical Carriage Building

The advantage of this plane over the ones in general use is that the iron is flush with the sides, and can be worked close up to moldings, &c If the sides are well rounded, as shown by face view, access can be had to points that cannot be reached by the ordinary form. Fig. 22 shows one of these planes with a concave face.
A full set of rabbet planes, seven-eighth-inch across the face, is necessary. There should be at least four with convex and four with concave faces. One or more straight, concave, and convex rabbet planes, with guards, as shown by Fig. 23 (page 39), will be found useful. The guards should be secured by set screws, so that they can be raised or lowered.
The scraper is a little tool, and one that should be used more than it is by bodymakers. It is a great labor saver, and there is nothing that operates so successfully as a flexible scraper for removing file scratches and other blemishes upon panels. The steel in these must be of the finest quality, and the sides polished very smooth. The edge must be trued upon an oil stone, and the edge turned by a triangular steel burnisher. The turning of the edge requires skill and care, but it can be turned to cut almost as true a shaving as a plane. The first operation is to rub down the flat sides. To do this, lay the steel upon a fiat, true surface and rub the burnisher rapidly the whole length of the scraper. Repeat this until the edge is very smooth; then turn the scraper up on end and pass the burnisher down or upóbut never both waysóon the edge bearing outward. This will turn a fine, true edge that will cut smooth, and heavy enough not roll off.
It is not necessary to say that bodymakers need files, as all must use them. But there are few bodymakers who have a good set of files. They generally content themselves with one or two fiat bastard and a half-round, and so long as they cut away the wood, they are apparently satisfied. Owing to desire to cheapen files, many of them are not properly faced. The true face is a taper both ways from the center, but many are made thick at the tang and tapered to the points. With form the heel is sure to scratch when filing large surfaces. Recut files should never be used by bodymakers, as they invariably scratch and weak points break off. This is due to the fact that, notwithstanding the old teeth has been ground out, yet there is an embrasure which reveals itself when recutting.
