    Hell, for 35 Canadian Pesos I wouldn't even have done the dye test... but this is the first time I've seen this done and I appreciate you going through it for my benefit.

    Best candidate for the fuckit bucket I’ve seen in a long time.

    Few things will have the male of the species gather around faster on the shop floor than announcing that a magnaflux test is being performed. More mesmerizing than a Three Card Monty game.

    "Known to the state of cancer to cause California" has to be one of the most perfect lines ever uttered.

    I work as a Civil Engineer in the frozen heaven hole of northern scandinavia. Part of my duties are inspections of old an new bridges. We had one assignment checking a bridge for fatigue cracks in its steel beams, acting as ties in a tied arch bridge. Mind you this bridge is about 900m long (which is like a gazillion feet and miles) with 14 or 15 spans. And me beeing the young hungry "get 'er done" engineer suggested: Hey, lets just use penetrant and developer and all the cracks will show up clear as day. This was an actually an idea from one of your vids, some many moons ago if I remember correctly checking a plastic part. Cant remember which BOLTR. WELL, 2 beams + cross girders for a 900m bridge... It would've taken about 1000 cans.. And I brought 4.... Not to mention about 6weeks of work. Luckily enough for me, because of the thick brittle paint used in old bridges here most of the cracks were visible and the customer agreed to just focus on those about 0.05mm thick cracks and their lengths and monitor them for the time beeing. First inspection was in -18, did one more -20 and just another one -22, cracks are growing, and new are forming. But the bridge still stand. Penetrating spray, or not. So, not to be used en masse. /Frozen mustache

    At least buying the replacement isn't the most expensive option - you could also draw up the whole thing and run off a copy on the CNC, then figure out how to move over all the extra parts... Could waste whole weeks with that option!

    I'm a machinist in Cornwall, PA at PRL inc. We build RO pumps for different US Navy subs and the new Ford class carriers. Everything gets X-rayed and dye tested multiple times throughout the manufacturing process. Great video as always. I found you back in 2013 when I was going to school to be a machinist.

    It's scary to think that AvE's little sproglet, who we only saw just last month (or so it feels) wandering into the workshop and talking to daddy in the sweetest shy little girl voice, is now going to be old enough to cause uncle Bumble a little nervous twitch of the eye every time she starts a sentence with "There's this boy at school......." ! You've gotta cherish the present because this present will be the distant past in the blink of an eye.
  • I'm of the mind that you should hide your crack in the hardest possible location to find. Unfortunately, my wife has really taken this advice to heart.

    Here's a tip if you're using dye penetrant. Just spray a small amount into a cap and brush it onto the suspect area. Much less messy. If it bleeds heavily into the developer wipe it off in one direction (clean cloth) and lightly spray on more developer. There's a lot more to it than you may think btw. Old NDT technician.

    I haven't done a dye penetrant test for 30 years, a great reminder. An early vijayo of yours, always do the easiest thing first, get on the Gargler, if it's less than $50 save yourself a headache.
  • If it's for the Dewglaw, apply the electrician mates rate of %150 mark up. Opps I meant handling fee and environmental disposal! 😀

    2022 and we're still using a barely evolved version of Oil and Whiting. If it works, it works.

    It's a head scratcher when grinding cheap cast aluminum parts and you see sparks. I have encountered un-weldable stuff.
  • @Jpilgrim30
    From someone who occasionally Tig welds cast aluminum you’re right. Most people shouldn’t bother even if they have the setup. It can be down right frustrating especially with cheap castings you deal with these days. You’ll find yourself chasing trash half of the way through it and trying to fill it back in. I’m in the automotive field and I only do it when a part is not available or is ridiculously priced. I’ll do some wheels here and there too but they seem to be a lot better than most cast parts.
  • @TheWtfnonamez
    Good shout. There is a very thin line between a "pressure vessel" and a really expensive pipe bomb.
  • @jaylittleton1
    I enjoyed my years doing NDT in the USAF. I can not testify to the chemicals you used, but the cleaner/remover for Magniflux and also Met-L-Chek penetrant systems was 1,1,1, Trichloroethane, also known as Methyl Chloroform. Clean parts made for good inspections and happy inspectors.

    I’m always a proud volunteer of the crack inspector variety.✌️
  • I have to applaud you squire!...... you truly are a master of words. Laughed so hard I missed half the vijeo..had to go back several times. Between King chuckles the terd, California's cancer and baby dolls misfortune..... what was this video about again🤔🤣
