Painting support assembly

A painting support assembly for supporting a panel in a horizontal orientation for painting the panel, said assembly comprising:

• a tripod having a plurality of legs each being pivotally coupled to a collar and a stanchion being slidably disposed in said collar, said stanchion having a top end, said stanchion having a plurality of holes each extending through said stanchion, said holes being spaced apart from each other and being evenly distributed along a substantial length of said stanchion, said tripod having a stanchion lock being movably integrated into said collar, said stanchion lock releasably engaging a respective one of said holes in said stanchion for retaining said stanchion at a selected height;
• a mounting block being coupled to said stanchion, said mounting block having a pair of channels each being integrated into said mounting block, said mounting block having a top surface, a bottom surface, a first lateral surface, a second lateral surface, a front surface and a back surface, said mounting block being elongated between said front surface and said back surface, each of said channels extending into a respective one of said first lateral surface and said second lateral surface, each of said channels extending through said front surface and said back surface, each of said channels having a first portion extending toward a. center of said mounting block and a second portion extending toward said bottom surface such that each of said channels has an L-shape;
• a pair of knobs, each of said knobs being rotatably coupled to a respective one of said front surface and said back surface of said mounting knob, each of said knobs being positioned between said pair of channels, each of said knobs being rotatable into a locking position having each of said knobs extending laterally across said first portion of each of said channels, each of said knobs being positionable in a releasing position having each of said knobs being displaced from each of said channels;
• a pair of extension blocks, each of said extension blocks having an engagement extending laterally away from said extension blocks, said engagement on each of said extension blocks slidably engaging a respective one of said channels in said mounting block such that each of said extension blocks increases an overall width of said mounting block wherein said mounting block is configured to support a smaller panel in a horizontal position to facilitate painting the smaller panel, each of said extension blocks having an upper surface and a first sidelong surface, said engagement on each of said extension blocks comprising a leg extending away from said first sidelong surface and a foot extending downwardly from said leg having said foot being spaced from said first sidelong surface, said foot of each of said engagements slidably engaging said second portion of a respective one of said channels, said leg of each of said engagements slidably engaging said first portion of a respective one of said channels, said upper surface of each of said extension blocks lying on a plane being coplanar with said top surface of said mounting block when said engagements are engaged to said respective channel, each of said engagements having a length being equal to the length of said mounting block, each of said knobs being positioned in said locking position when said engagements are engaged to said respective channel to inhibit said engagements from being removed from said respective channel;
• and
• a plate having a pair of grips each being attached to said plate, said plate being positionable on top of said extension blocks and said mounting block wherein said plate is configured to support a larger panel in a horizontal position to facilitate painting the larger panel, each of said grips engaging a respective one of said extension blocks when said larger panel is attached to said plate, said plate having a topmost surface and a lowermost surface, each of said grips comprising a leg extending downwardly from said lowermost surface and a foot extending away from said leg having said foot of each of said grips being spaced from said lowermost surface, each of said grips extending along opposite sides of said plate from each other, said foot of each of said grips being directed toward each other, each of said extension blocks being positioned between said foot of a respective one of said grips and said lowermost surface when said grips engage said extension blocks.
