I'm pretty excited to build a Wilson II, but I'm hoping to reduce price by sourcing all the materials myself. Unfortunately I'm find a lot of variation. I see the bill of materials lists the lead screws as THSL-300-8D, but when I type that into the Google, I still get variation. What thread pitch is needed? Also, what is the outer diameter of the nut that goes into the carriage?
If you have any info on this, or even on other ambiguous parts, I'd appreciate it.
