Luna-Tic improvments

Sorry for the random question but wanted to ask as I'm thinking of using hdpe next. Does it hold a thread?

[Maxamuslead]

not really, it wears out quick,

[Roboteernat]

no, threads do not hold in HDPE, most people just use wood screws or machine screws to screw panels together.

Yeah, it'll hold woodscrews, but not really bolts or anything with a thinner thread.

[maddox10]

HDPE doesn't hold a thread. Better to use barrel and/or crown nuts.
Or the old and trusted angle/bolt/nut combination.

[Roboteernat]

yes, i went to add bolts are best but got distracted with actual work stuff bolts and angle are the way to go

Ahh I can see why a 30-amp might have been cooked. Still it's strange, capacitors only normally release all their charge that quickly when you bridge the contacts together. Hope the new link works out.

Capacitor charging can cause some startling sparks but shouldn't really melt connectors. Rather than use huge Andersons (which I found to be terrible for spark suppression), have a look at the Hobbyking XT90 connectors with built-in suppression resistors - much smaller & lighter than the Andersons and they really work.

[cjsowry]

that was my back up. The xt60 was "fine" but I wanted the connecter mounted to the chassis and pulling it out I often pulled the wire and the soldering came loose. With the Andersons they have the bolt hopes, so I can attach a strap making it easier to remove!! we'll see. Need an Anderson for the heavy so its not wasted money!! thank you.

OK thanks for the info. Do you need to pilot hole for wood a screws or will they go straight in like 2x2?
