In the video, I forgot to mention that instead of using set screws for my carriage gibs on the lathe, I shimmed it using rectangles of aluminum beer can placed between the threaded rod studs. I was originally going to spend some money on brass shim stock but figured I’d give the cheaper option a try first. It worked very well and since I used individual pieces for each space between the studs, I was able to more finely adjust the height. I think I spent close to 3 hours adjusting until I was happy with the complete lack of slop and the smoothness of travel. The nylon lock nut replacements worked very well too. Basically, I just took off one of each different size I needed, noting how many I’d need for each axis, and made a trip to Fastenal. The upgrade cost me about $5 in nylon nuts, $5 for the threaded rod (used on the carriage gibs), and $10.00 for the 1/4 x 1 x 4 brass flat stock (which I milled down to size). It was my first time working with brass and really like how smoothly it machines.
