Honestly I hadn't intended to work on this more for a bit, but I had gotten my hands (paws) on a replacement wooden board for my keyboard tray, and when putzing around with my existing tray board to guage how and when I wanted to swap it out, I accidently broke it.
So... when putting it back together I just mounted the slides into the new wood board, and it's working great!
Feels way more solid than the old one did. Much sturdier, is holding itself together way better
This weekend I'm intending to rework how this is mounted to my desk to let me get rid of the spacer blocks on the top that stop this from running directly into my knees.
First I'm gonna mount another board to the bottom of my desk near the front, where the old crossbar used to mount to the desk. Then I'm replace remove the clamps from the mechanism, as that'll leave me with new holes that I can run screws through into the new board.
Once I do that, I should have the keyboard tray mounted firmly to my desk at about the same height it's currently at, but without any unsightly clamps/spacer blocks taking up a ton of room on the top of my desk
Then, at some point when I get tired of looking at the bare wood, I'm planning to take it all down, sand it a bit more thoroughly to look all pretty and stuff with some nice rounded corners, and then stain it
All things considered, this whole project is more a call for people to modify and tinker with the stuff they own. A lot of these things aren't that hard to do, you can do them with just about anything you've got on hand, and they can vastly improve the quality of the things you own for incredibly cheap
