Breif instructions fo adjustable stool
Derek.
Adjustable foot stool.
Three frames of 400mm. by 500mm. finished size, made of ex. 50mm. x 25mm.
I Cut to finished size and used the Band saw to make the through mortise and tenon joints, glue these together.
Rout a rebate on the hanging sides of each frame to take the Piano Hinge, countersink the holes in the hinges.
Cut four 75mm. triangular blocks of timber to support the castors, glue and screw on the corners at the bottom of one frame to be the base.
The legs and the leg supports are of the same timber but the width is reduced to 30mm. Each one must be just under half the length of the stool.
Cut 3 notches into the fixed supports, keeping the vertical cut angled to support the leg. Either fix with glue and biscuits or screws to the sides where shown, making sure that the teeth are pointing towards the hinge end each time.
Cut the legs to size and put the taper on the end, then using a half-lap joint fit a ledger bar across to hold the legs in position, (missing on the one shown, sorry), Using screw cups or screw cup washers with Brass screws as pivots screw onto the frame.
Now is the time to fit the piano hinge with C/S. screws.
Fix your castors in place.
Cut a 9mm. thick piece of M.D.F. to fit the top, get a piece of dense foam cut to size, (cuts well on the Band saw, or use an electric carving knife), stick to the board with spray adhesive or similar, and wrap your upholstery material around, folding in the corners, staple into place.
Turn your stool over and drill and countersink the frame and fix the board.
In the pictures the one shown is just made from deal, but most of those I have produced have been in Oak, Iroko and mahogany types, stain if wanted and polish, Danish Oil, Plastic Coating, or just seal and wax.
