Chinese spindles - reuse the old connector. If you can't do the soldering, some stores offer a service to do that for you for a fee. The shield is usually soldered at one end and buy clip on ferrite beads for power supply cables. Another thought, I found that the housing taking the above style cable gland was aluminum and could not easily be upgraded to a bigger size. I ended up using 2 stage enlargement the first was metric to imperial! Yes, there is another issue! Also, my cable for a 4KW spindle needed to be 10AWG shielded cable and the connection housing was only designed to take 12AWG. You can shave down the outer insulation to get it into the gland and seated. The extra cable weight can be accommodated by putting some angle iron and a cable retainer (bigger gland) on the Z-axis plate to spread the load. You may need colalt steel drill bits, cutting fluid and taps for threading the new holes. Do it well, do it once! Dave
