Even more efforts deliver bochkoobraznye columns. Here usually do many ring beacons of different diameters, and consequently, and many various ring templates for their installation.
At furnish of rectangular columns to provide vertical position of sides and to define a thickness nameta, usually apply wooden majachnye rejki. Them consistently transfer on the one hand on another - four times establish and remove (fig. 85).

But there is an inventory metal string template (fig. 86), with which to work faster and is better.
a Fig. 86. The scheme of the string template fixed on a column :
1 - a frame; 2 - a hook; 3 - the screw-handle; 4 - a string on a wire; 5 - persistent bolts; 6 - a column
Below and above on a column metal frames are fixed. Between them on column corners strings from a steel wire in diameter 1,5 are tense... 2 mm which serve as beacons.
Each frame consists of two pieces of a metal corner. In vertical regiments from both parties carving apertures through which take place the basic bolts fixing position of a frame on a column are made. Through vertical regiments coupling bolts are passed also.
Horizontal regiments of a corner have longitudinal grooves with mobile krjuchjami for fastening of strings.
Template Installation begin with fastening of the top frame, then put bottom and between them pull strings. A reliable tension of strings reach, rotating the lambskin nut which has been put on the top hooks which - unlike bottom - have a carving.
The Barky template suits several standard sizes of rectangular columns, for drawing of a plaster layer of a different thickness. The set sizes always can be received, using persistent bolts and moving krjuchja with strings on longitudinal grooves in horizontal regiments of a corner of a frame.
On a surface of columns carry out also figured draughts. Especially often do so-called kanneljury - vertical semicircular flutes - and name such columns kannelirovannymi.
Kanneljury on round not narrowed columns carry out a template at first on one half, then on the second. The ends kanneljur undress malkami.
Kannelirovannye of a column with entazisom plaster, using the templates moving on the vertical directing. Work in this case carry out parts, instead of on all circle. A template for such processing do with two sled connected to a sample board sharnirno - on loops (fig. 87).

Kanneljury on equal rectangular columns extend templates on hung on a column directing rejkam or to strings of an inventory metal template.
Carry out on columns and spiral draughts. For this purpose round a column trunk navivajut on the set step a rope, rubbing clean ("яЁшьюЁрцштр ") its plaster solution. The rope serves directing for a special template (fig. 88).

Bases and round parts of capitals (if they are manufactured on a place, instead of are established in the form of in advance cast modelled details) extend by means of templates on ring directing or on already plastered surface of a trunk of a column.
