Instructions for Assembling Stretcher Frames with Universal  Braces

 

SB1

Stretcher Frame Components:  stock size stretcher bars, braces, brace brackets, screws and keys.

Tools Required:  rubber mallet, Philips screwdriver, measuring tape.

Stock30x40BracketWEB

All stock stretcher bars 40 inches long and over should be braced. This applies to both our Standard Bars and Professional Bars.   The 30″ x 40″ frame shown on right requires only one 30″ brace.

 

Stock48x48BracketWEB

The 48″ x 48″ stretcher frame shown on right requires two 48″ braces, one in each direction.  A “Dado” is machined in the center of all stock braces that are 40″ and over to permit flush nesting of the intersecting braces.

Assembly of Frames with Stock Bars & Braces

The first step is to fasten the brackets to the stretcher bars.  Measure and mark the center of the bar and the bracket,  and using 2 screws,  attach the bracket to the bar with the back edges of the bar and bracket flush (see drawing below).

Drive the screws in so that the heads are flush or slightly below the surface.  CAUTION: to avoid splitting the wood do not drive the screws too deeply into the brackets.

 

DrawingFlushWEB

Note the positioning of the bracket on the Standard and Professional Bars.  The back side of the bracket should line up flush with the back edge of the bar.  This provides the maximum “set-back” (space) between the stretched canvas and the braces.

Stretcher Frame Assembly

 

FrameAssemb1WEB1.  For frames with 2 braces, fasten both braces together with the hardware (screw and sleeve nut) provided.

FrameAssemb2WEB2.  Attach the bottom stretcher bar to the braces by sliding the brace slot over the bracket.

FrameAssemb3WEB3.  Attach the right stretcher bar to the bottom bar and horizontal brace.  Use a mallet to tap the joints tightly into place.

FrameAssemb4WEB4.  Attach the top stretcher bar to the right bar and vertical brace.

 

FrameAssemb5WEB5.  Attach the left bar to the top bar and horizontal brace. Tap all bars together so that all joints are fitting tightly and the frame is assembled square.

FrameAssemb6WEB6.  Check that the frame is square by measuring the diagonals which should be equal.

FrameAssemb7WEB7.  Your frame is now ready for stretching the canvas. See our instructions for How to Stretch Canvas for more information on this step.

FrameAssemb8WEB8.  After the canvas is stapled to the frame, place 2 keys in each corner and one key at the end of each brace.  Tap keys in to provide desired tension in canvas.
