Good day to all. The lady I built it for wants a shelf that slides from the bottom left shelf. I am looking for some undermount slides. The slides need to be completly hidden. I found some but they were about 1-1/2" tall. I need them to be about 1/2" - 5?8". I datoed out the shelf and mounted them in the dato. I purchases some sidemount door slides from homedepot the heavy duty 100Lb ones and layed them flat instead on how they were intended to be used. It slides well but it dips a bit when extended. She is going to put a record player on it so it will not have a lot of weight. I only have about 1/2"-5/8" to play with. Any advice would be apperciated. I built this just for something to do I'm unemployed and board. Shelves are faced plywood and the rest is solid oak.
