DO NOT MIG WELD YOUR FRAME WITH A HARBOR FREIGHT WELDER

So, Brit calls me earlier to tell me about Ritchie (the new owner of my old gen-4) and how he blew up the motor in it and the lower rod bearings went everywhere. I was bummed to here about it, the rod bearing was the only thing I didn't replace when I built that motor, but judging by the last time I saw the bike, he didn't maintain it at all and it probably sucked a bunch of sand out at dumont.
So I get off the phone and 5 minutes later Brit calls back and tells me he talked to ritchie and he rewelded the whole damn frame because my MIG welds were cracking all over! :shock: ooooops :oops:
I do remember keeping a close eye on those welds while I had the bike, and none of them ever cracked while I had it, but I'm guessing that while that rod bearing was on its way out the motor was vibrating like crazy and tore up all of my shitty welds :oops: I owe him a beer and an appology next time I see him! I'm just suprised that it only cracked and never separated at the Y or anything, just glad no one was hurt and it just turned into an inconvenience of having to reweld...

Did you tack stuff with the MIg and get it Tigged to finish or MIg the whole thing?

I MIGed the whole damn thing. Every bike I did after I tacked with the MIG, then had a pro TIG it. I built that gen-4 for myself and didn't think I'd be selling it, but I really didn't like how the gen-4 chassis handled, so I build a gen-3 and sold the gen-4 to ritchie for a low price and I openly told him it was MIGed and to keep an eye on it, and I told him that was why I was one of the reasons I was selling cheep. I gave him a verbal list a mile long of things to watch out for, tuning recommendations, etc. I'm guessing it all went in one ear and out the other while he was having wheelie day dreams :lol:

DO NOT MIG WELD YOUR FRAME WITH A HARBOR FREIGHT WELDER

If done correctly MIG on aluminum can do a good job as a lot of production welding done on frames uses this process. I would stay away from any power supply if it ran off 110. I have a Cobramatic at work for my MIG and it works great. Just make sure you have it spraying in good and hot and you can mix a bit of helium in to help. I always carbide the starts and stops to aid in tying in the wraps and such and brush between passes. As with TIG on the frames you need to get 100% penetration to get the strength or you're pissing in the wind.

the MIG process wasn't the problem, the harbor freight MIG was... its 220v, but only has 4 power settings min, max and 1, 2 respecively. max 2 was burning clear through everything and max 1 wasn't getting quite enough penetration. A power knob would hve made all the difference in the world. It did stay together though until the bearings went, I've seen steel frame bikes break mounts from engine vibes too. Hell, it still held together better than some of those UK built bikes :lol:

If your motor is screwed up it will shake a tig welded bike apart too.
