What you will need:

A 12v, 13v, 14v, 15v, or 16v, 2.5 Amp DC capable power supply with a center positive 2.5mm barrel connector plug at the end. I prefer 12v since these are very common these days because they come with home WiFi equipment that gets renewed quite frequently.

A labeler machine or printer (for the warning sticker). This is important, I'll tell you more about that later.

Hemostats. These are highly recommended because you will have to solder in places that are not easy to reach.

A soldering station capable of 330°C. This temperature setting is relevant because you will solder on elements capable of dissipating heat.

A small screwdriver for calibrating the motor speed.

A copy of 1050 disk drive diagnostics diskette for final tests and calibration. Find the software here and have it ready before beginning: https://archive.org/details/a8b_1050_Dis...
