    Lol, well, not to toot your horn for you, it was a good idea. I had a vision of exactly the stitch-weld, crud-in-gap scenario you described...you must not have been wearing your tin-foil hat...

    I only use a spool gun, since it's all my machine can do out-of-the-box. It's heavy to hold, bulky to use, and mostly made from plastic. The liner is about 5-in long (plus), but the rollers are...

    Hehe, thanks CrazyBillyBob. For laser welding, I'm not sure my argon tank is big enough though, but I was considering picking up one of these little guys.

    Update

    After some time mulling (and...

    Being stainless-steel, it's a bit less flimsy than the zinc or brass kind. Also, it doesn't open all the way, only 90* or so. Finally, the tube it's welded to is thin wall, maybe 18ga, so heavy...

    Though you may not be able to tell from the earlier pic - it was a horrible quad-skew-octo-deco-trapazoidogon. Not a box at all. Now it's a much nicer fit, though nothing's perfectly square, the...

    Drilled holes into the inside-face of the hinged assembly, big enough to get the screw-head in, the opposite face has a thread-size hole. Stuck a sharpie through the holes to mark the small hole...

    Update: New power supply location + start of an enclosure

    Woke up one morning with a vision: Crucible exploded in furnace...hot aluminum leaking down drain, dripping through holes in my...

    You're right! I found a 1/4" one banging around in a box, ground some back-relief into it and a hole was made :D I'm not counting change, but it was much easier than the tear-drop one. A bit hard...

    Ah, okay. I have some of them, but they're more expensive, didn't wanna ruin them :D Grind back-relief on them? Will an Al. Ox. wheel do it or must I have diamond?

    Just a reminder too that while maybe less-desirable, there are people using hair-dryers as small furnace blowers. These things are super-cheap at second-hand stores, and/or found by rooting around...

    ...I dunno what I'm talking about, but from what I saw, looks like the aluminum is over-done (too hot). It's also good that you recognized a few potential dangers w/o (spoiler-alert) burning the...

    Ahh okay, I think I get it, yeah, the travel is too great for, it's got to collapse more than just two EMTs would allow. Though, running with this EMT idea (stuff is almost dirt-cheap), I came up...

    Still conflicted about where/how to mount the PSU and control box. Trying to pick a location that's convenient from the front-side of the cart, yet out of the way WRT molten metal dealings. Briefly...

    You can only deploy creative options on a drain hole that's not there. Making a drain in already cured refractory is crazy-talk. Don't worry about the details, add a 2-in hole and figure out what...

    Hmmm, why would I split the side? I have access to both screw ends, though the top is easier. I was thinking sheet-metal too, though not sure about flashing. That stuff's so light-weight I'd be...

    The gearbox does heat up a bit, but it's rated for continuous duty, so...ya, you're right, it's gone.



    Hmmm, there is one spot, near the top where it's either bent or some threads got mashed...

    Those are sexy! Care to post some closeups or describe the build? I'd love to make a pair like that. I started one using Gingery's design, but it's just too flimsy for an A8 or larger. I also need...

    Eek! I wouldn't use this blower for that (or at least have a few spares on hand). That ABS plastic will turn straight into bubblegum at the smallest sight of molten iron radiation. It's Tg is...
