THE CUTTING OF THE PLATES OR THE LATHS

Plates

The cutting of the plates does not pose a particular problem if it is not on the gangways because space is restricted there.

The installation of the plates is started from the axis however for better a comprehension we will not take account of that in our explanatory sketches.

Figures below:

fig. 1: we imagine 2 fictitious lines called lines of cuts to approximately 3 cm of the edge ext. and int. then us prédécoupont the plates according to these lines.

Fig. 2: we will withdraw these pieces which we will re-use fig. 4 then one shoed the final tracing while placing a blade over the plate by taking care to follow the edges well by leaving the thickness of a joint if it is necessary the easy way will be to take a fall of plate by cutting out there a piece from 10 to 15 cm length and a width, of a blade with the two contiguous grooves, for the tracing against walls verticale(roof, bulwark, box, etc....)

fig. 3 after the tracing it any more but does not remain us to carry out cutting most properly possible.

Attention the slope of the cutter must be sufficient for cutting cork without tearing off well it

LES LAMES

laths

curved laths

One will contrary begin the installation of a bridge out of blades with the edge external with an installation by plates and thus by the external bank blade only the last blade will be cut out by the blade of interior bank and thus according to the method previously explained. It will be on the other hand useful, to have a more regular tracing, to use a small wood rod. Indeed the curve of a rod which one curves over the tracing will rectify the defects.

 

	Curve lath installation sample show steps by steps

 

Margin planch

Cutting is relatively simple for the laths

the cuts on line will be carried out with a square with 90°

The tracing of the cuts of mitre is carried out easily by superimposing the two blades to be assembled and by thus tracing their intersection, then one will use it bevel-square which positioned on the tracings must give us a clean and regular cut. By precaution to test has you this technique with falls.

 

"LA FOUGERE"

The central part of the bridge is carried out starting from a virgin plate in which one will be able to also cut particular parts. They are in general much broader than the blades of bridge. Simplest is a very right band but on a fine prow, such as one finds them on the sailing ships, cuttings of blades finish at a peak too also frayed it is preferable to carry out a fern. Two types of ferns are realizable. See below.

On figure 5 the tracing and cutting are easier to realize Tracing of the axis on the part one positions it over the blades and in alignment with the axis of the bridge one defers the intersections with the blades of bridge then one traces a parallel to at least 2 cm of the edge one traces with the square the perpendiculars of the edge until the parallel finally one connects the tracings as on the fig. 5 then one carries out cuttings by repositioning the part one can finally trace the cutting of the blades without forgetting the joint to have regular joints it is enough to take a fall of turned over blade and supports some in bottom of rabbet

fig. 6

on the fig. 6 the tracing and cutting take again the same points as previously. A circle positioned in tangent will be used to soften visually the cutting of the fern on the other hand the cut with the cutter will become more delicate and will require a completion with the sandpaper to obtain a beautiful result
