• Scam Alert. Members are reminded to NOT send money to buy anything. Don't buy things remote and have it shipped - go get it yourself, pay in person, and take your equipment with you. Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance.

  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

I have seen no evidence either to back this up or to refute it, but I believe I read somewhere lone ago that this is actually less reliable than simply crimping. Apparently the wire is prone to breaking at the transition from stranded to soldered. Maybe someone has a reference or some further info on this?

It is if it’s in an area that is subject to flex.

Shouldn’t ever solder in a flexi application. Inside a control panel or in a permanent install type application, it’s no problemo.

Splicing via soldering in a drag chain on a CNC gantry = no bueno.

Most other applications of soldering = totally fine.

It is less reliable. And I have seen the evidence to prove that. However, as I said in my first comment sometimes it is fine such as where the wire connection does not move. As I also said, I only use that when I can't use a terminal. I usually find it MUCH better than bare wire.
 
My suggestion is that if you have a lot of these to do, get good tools and use the pre-made crimp ends. If you are only going to do a few, then the extra speed won't be worth it versus spending the time required to make a good connection directly with the wire.
