Top Panel
Finally got a bit more work done. The top panel is attached by 10 screws with nuts plus 4 screws that will attach the handles.
First the frame and top panel are lined up and clamped to a piece of chipboard. The holes are then measured and drilled with a cordless drill.
To cut the fan hole I screwed the panel down to a piece of chipboard then drill the pilot holes using a template from Sketchup. Then cut the hole using a hole saw.
It all fits together which is always good. Also now i have a cool chequerplate drink coaster.
Front Panel
To drill the attaching holes for the front panel I clamped the panel down and drilled straight through from the outside.
Because the top and bottom of the frame sits 3mm forward of the uprights I need to put in these little spacer pieces along where the screws go through. They are araldited in place.
The front panel is clamped and hole sawed in the same way the top was.
