Short video about a test for linkage of the cross slide to the carriage sleds of my home made metal mini lathe. I have some questions, what are your possible solutions?

A DIY composite two-stages pulley, makeshift indexer, and lathe drill holder jig are showcased here in a challenging situation.
Making the pulley that drives the spindles lathe using the same lathe to make the very same pulley is a challenge. Because of the design of the spindle of my lathe I was not able to find a ready to use pulley off the shelf, and ordering one at the machine shop gave me a staggering long time to deliver. So I got creative and I made the pulley from scratch. With a piece of thick steel tubing and an old aluminum flange and some epoxy resin I made a pulley that is suitable to be driven through a poly-V belt, as required by the motors, salvaged from washing machines.

In the video youll see a linear scriber that Ive made myself, video: https://youtu.be/f9tA4i2xqjM
The motors are driven with an electronic speed control (ESC) that I designed myself, video here: https://youtu.be/5zRCCL2JZTI
A contactless RPM meter (tachometer) is featured, Ive shown how it is made here: https://youtu.be/RlAIcnxVLZE; here: https://youtu.be/iQ5vwq0JoKE; and here: https://youtu.be/fzcXJIGZSHA
