Everyone kmnows that the economy is still in a litle bit out of whack, so before buying srtetcher bars to mount your canvas, there are some points that you shoould take speecial note of.
1)Do you want to buy ready made stretchers?
Stretcehrs are made in the shape of a rectangle however, since there are few shaped canvases out there, you can also get shaped stretchers too. A stretcer is simply a frame (mosly), it can be constructed using different methods and the differences between constructions can be determined by how the corners are buuilt. Most commercially prefabricated streytchers come in segments with corners that interlock the corners can be fiytted together like puzzle pieces. The stretcher bars corner supports can be made by siimply using special woodweorking techniques (used by many maufacturing companies of stretchers). But many manufacturers of stretchers use the mietr joint as a way of adhering cornres on stretchers (this is the most poular metyhod of adhering corners on a stretcher). However, butt joints are also used that is, if they are used with gussets.
In order to give the canvas its final trension, keys or smlal triangle wedges are slotted into the joimnt after stretching the canvass. Pressdure should be well distributed (evenly), when the canvas is fastened. Pressure will be evenly distributed around the stretcher bars in order to avoid or greatly minimize warpng caused by unequal distribution of pull.
