I have seen numerous ways to support a drawer. In this case, I knew that I would have to make my own. The drawer runners for the lower drawers (between the legs) would need to be around 5 feet long, and the runners for the core of the table would have to be 9 feet long.
I was concerned about using hardwood since I would not be able to wax them once the table was built, so I did some googling around and starting looking at HDPE for slides. Then the idea became more clear – I decided to make some C channel out of maple to support the HDPE, stagger the joints as necessary, then put them into the dadoes I had already cut into the legs and the web frames.
Attaching HDPE to anything can be tricky – it is a form of wax, according to the always correct internet. Regardless, it is very slick and probably wouldn’t take to any adhesive. More research got me into deciding to scuff up the plastic with some sandpaper and epoxy it in place. I still didn’t trust the epoxy (not sure why), so I also put screws in from the backside.
Attaching the slides was pretty easy – just put them in the socket and attach with glue and a counter sunk screw.
I had also cut dadoes on the outside of the legs. The thought was to use these points to attach some sort of shallow cabinet or a cleat board.
Next part is a crazy long drawer.
