Dale's Interferometer is great but it had 3 different screw sizes (imperial). I standardized on one size: M3 (metric 3mm) threads which I have tons of and are at my local home depot. Also I added a paper holder. The paper holder still uses Dale's #8 screw but works with M3 as well. I also made the shaft that supports the ball and socket mirror holder thicker and stronger.
I sell the metal parts for this or have information where you can get them and optical parts on your own. Also I have assembly and usage videos for this and the xyz table. All here:
