Trailer brake circuit breaker advice.
  • Your fear is burning your truck down because of the breaker auto-resetting and causing a program, right? Adding a fuse before the breaker will allow the breaker to operate normally. But if it's a serious problem, like an actual short and not a temporary overcurrent, the fuse will blow and not reset.

  • I could use a GPU recommendation

    Thanks for the advice. I grabbed a gtx 1070 off eBay for $70 all in. The listing says it has two bad HDMI ports, but that's fine because I only use one monitor. Thanks

    I'm looking to upgrade the GPU in my desktop. I don't game anymore so the PC is more of a workstation. What I currently have is a reason 4850hd. It's old, but it wasn't when I bought it. I had two in x fire for a while but one died.

    The biggest limitation I have is running fusion360 is terribly slow when parts get complicated or I have multiple designs open. It's bad enough the my Asus rog laptop is faster and smoother at running fusion than my desktop even though my desktop has a now powerful processor and way more RAM.

    So what I'm looking for is something in the sub $100 range that's better than what I have and will be better for fusion. I realize thats a pretty wide margin, but that's all the stipulations I have. I'm completely open to second hand cards of off eBay as well. I know that sometimes yesterday's to end card is better than today's economy hardware.

    Thanks

    Amazon Prime Video will start showing ads on January 29th unless you pay extra for ad-free
  • I am in the exact same boat. The removal of "free" rotating streaming video content and limiting it to only Amazon funded shows with "free with prime" videos being hosted by 3rd party apps (fuck off, freevee) was bad enough but to start showing ads was the final straw

    I cancelled my prime today. $150/yr. I can wait a few extra days for the things I need to order

  • Weird drill press at my workplace with multiple heads
  • Does it actually travel down with the quill or is it stationary? It's obviously powered by the belts. My guess is it's a 2nd op quill and that one is either pops out slugs that have been cut but may leave hanging Chad, or it's simply a smaller deburrer than what's in the main quill.

  • Southbend 9" motor potentially bad? help fixing or buying vfd
  • The motor will be printed with a frame number. You can match up the hp, frame number, and shaft diameter and it should work. Most old lathes came with reversible motors. Not all electric motors can be reversed.

    Chances are if it's stopping and starting then you have a bad capacitor. Here's a link on how these motors work and what to look for to fix it https://woodgears.ca/motors/reversing.html

  • What should I know before welding flux core for automotive work?
  • Regarding your points:

    1. this just requires practice.

    2. the settings require more adjustment for sure. The voltage is set based on the wire diameter and metal temperature. Wire feed speed is set based on metal thickness. There are charts you can look up that give you good starting points for dialing the machine in.

    3. mig should have virtually zero spatter, and what is there should just brush off. If you're getting a lot of spatter there are three likely issues: a) voltage is set too high b) contact tip to work piece is too far c) the material is dirty, such as rust or paint, heavy mill scale, or a coating like zinc or galvanizing like on aluminized exhaust tubing

    You'll find that the more you use mig, the more you will prefer it. It's an all around better process for home hobbiests and light fabrication.

  • What should I know before welding flux core for automotive work?
  • Unfortunately, many of the problems you had with stick will follow you with flux core. Flux core as a process was intended to be more productive version of stick welding. It requires more heat than gas shielded mig to burn the flux to generate the shielding gases.

    If you can swing the extra cost for a solid wire mig welder and shielding gas, you will have a much easier time with any automotive welding. You might be able to struggle through an exhaust will flux core, but it's going to be a struggle for sure.

  • Testing an auto darkening welding helmet
  • The light from welding is orders of magnitude brighter than the sun or any led flash light you can hold to it. If it flashes at all holding it up to light then it will most likely work just fine when welding.

    Rest assured that even if you try to weld with it and it DOESN'T darken, the lens still protects from the uv rays. You should not continue to weld with it if it does not darken as it will so be bright and will strain your eyesight, but it won't cause any physical harm to you.
