Thread: Broken spindle connector

Element-14 or RS should have a good variety of plugs.

One I found with a quick search which might be a suitable replacement.
HA4-FK-TE-PM-P-M20 - EPIC - KIT, PANEL MOUNT HA4 4 WAY | element14 Australia

Ch4is,
I have a couple of these plugs/connectors on hand but they would require modification to the spindle to use, as would the square ones you showed.
While I did say I'd be willing to make such modifications, the way my metalwork is going these days, a straight replacement may be safer

Have a look at this thread as well.
I use the Amphenol plugs because they are power rated for use on the spindles and also they are MUCH better quality than the one the spindles come with. You don't have to solder them either and they can also take a much bigger wire.

You beat me to it Bob

A quick measurement of the Amphenol socket shows it would need at least a 23mm hole, the existing hole is 16.5mm.

Bearing in mind that my spindle is water cooled, there may not be enough room to bore it out
I'll have a closer look tomorrow.

The spindle in the linked post was my air cooled spindle, but I have upgraded to a larger water cooled spindle and have had no problems installing the Amphenol socket so I can interchange the spindles if required

Took the spindle apart and measure and I agree that the Amphenol socket will fit.
the new hole will just hit the 4 mounting holes for the existing socket. I'll have to drill/tap an aditional hole for the earth wire - it was using one of the existing screws.

5 minutes on the lathe to bore out the hole to 22mm, 10 minutes to drill and tap 2 mounting holes. (not as straight as I'd like )
And there's enough of the tapped holes for the original connector left that I can still use one to attach the added earth lead.

thanks for the suggestion, less painful than I thought it would be.

Hopefully problem solved. Good luck with reassembly. Reading through I was about to offer a loan of chassis punches to open the hole out, but remembered that you had a lathe in the kit.
