A support cradle (11) adapted to support a tool (13) having a cutting element associated with a cutting face (15) at which the cutting element is accessible to a work piece, the cradle in use to be associated with guide (21) comprising a support face (23) and a guide face (25) which is to be coextensive with the support face, the cradle having a lower face (27) which is to be maintained in face to face relationship with the support face and a side face (29) which is to be maintained in face to face relationship with the guide face, the cradle configured to receive and support said tool such that the cutting face is located above the guide and is accessible across the guide face whereby with longitudinal movement of the cradle along the guide face the cutting element is caused to move in a path having a form corresponding to that of the guide face, clamping means (35) provided from the cradle and adapted to releasably engage and support the tool on the cradle such that the cutting element is held in fixed space relation to the guide face.
A support cradle adapted to support a tool having a cutting element associated with a cutting face at which the cutting element is accessible to a work piece, the cradle in use to be associated with a guide comprising a support face and a guide face which is to be coextensive with the support face, the cradle having a lower face which is to be maintained in face to face relationship with the support face and a side face which is to be maintained in face to face relationship with the guide face, the cradle configured to receive and support said tool such that the cutting face is located above the guide and is accessible across the guide face whereby with longitudinal movement of the cradle along the guide face the cutting element is caused to move in a path having a form corresponding to that of the guide face, clamping means provided from the cradle and adapted to releasably engage and support the tool on the cradle such that the cutting element is held in fixed space relation to the guide face.
A support cradle according to any of the preceding claims wherein the lower face is provided with a set of first supports which are to support the lower face in spaced relation from the support face.
A support cradle according to any of the preceding claims wherein a support element is provided on the cradle, said support element being transversely spaced from the side face, the support element, in use, being engageable with an elongate guide element provided along the support face, said guide element being parallel to the guide face, the engagement between the support element and the guide element maintaining a spacing between the guide face and the side face throughout the range of longitudinal movement of the cradle with respect to the guide.
A support cradle according to claim 10 or 111 as dependent from any of claims 6 to 9 wherein the engagement between the support element and guide element is adapted to enable the cradle to move transversely on the support surface as a result of transverse displacement of the second support members in their movement over the guide face.
A support cradle according to any of the preceding claims wherein the clamping means comprises a guard which in use is supported to the side of the cutting face which is opposite the guide, said guard extending outwardly from the clamping means to overlie the space outward of the cutting face.
A support cradle, according to any of the preceding claims, provided by an upper portion and a lower portion, the lower portion being engageable with the guide and the upper portion adapted to support the tool, the upper portion being displaceable from the lower portion, locking means provided between the lower portion and the upper portion to lockingly retain the portions in fixed relation to each other.
A support cradle according to any of the preceding claims for which said tool is a hand planer.
A guide, adapted to be used with a support cradle intended to support a tool having a cutting element associated with a cutting face at which the cutting element is accessible to a work piece, said guide comprising a support face and a guide face, which is perpendicular to the support face and having a longitudinal extent, the guide being adapted to receive the cradle such that a lower face of the cradle is in slidable face to face relationship with the support face and a side face of the cradle is in slidable face to face relationship with the guide face, the guide comprising a surface extending from the guide face in opposed relation to the support face, said surface being adapted to receive and support the work piece.
A support cradle substantially as herein described with reference to the accompanying drawings.
A guide substantially as herein described with reference to the accompanying drawings.
