yea thatll work but its a good idea to get the weld as smooth as you can with the tools you have before you slap on the bondo. a selection of metal files works ok if you dont have a grinder. Also to make the bondoing go easier you can cut it down with a heavy grit paper like 60. then go to like 100. after that you can get a tube of spot puddy. its like a really fine bondo that doesnt need mixing and is easier to sand and make look good. you can get it at most auto parts stores. that works great for a finish coat then you can primer. Also if youve never done bondo make sure you mix it real good and get the color nice and even it doesnt take much hardner but mix it well :thumbsup:

metal fume fever. is the name of what happens with zinc fume poising . it sucks bad ya want to puke feel like hell and every joint in your body feels like its stuck .just like a real bad case of the flu . lungs hurt ,there full of crap that wont move . i have had it a few times messing with stuff and not knowing it had zinc in it . welding or high heat is the most common way to get it but grinding on zinc plate can get ya too . never heard of the bloody dump thing before , thats not good get to the doc if you see that going on .
milk helps best thing is dont get it . work out side up wind of it or use a fan at your back . use dust masks when sanding on it

Hey Hojo,
I tried to blow up the picture a little to see the welds and from the looks of the bead on the motor plate, you may not be getting good penetration of the base metal (irregular and thin bead) , with that said I would be concerned about the strength at the steering stem if the same thing is going on there(I couldn't really tell from the pic) . I'm noy trying to critisize your work, just don't want it to snap on you. My only suggestion is keep an eye on it for cracks after a few rides and don't cover it with bondo until you're sure it will hold. oh, and wear a helmet.:hammer:

This was my first welding experience, and I know the welds suck and might not have penetrated all the way, but so far nothing as cracked or broken off. I am also worried about the steering stem and that is why I wouldn't ride this bike without a helmet. Im gona reinforce the all the welds and turn up the amps so I get good penetration. Thanks for your comment :smile:
Make sure you keep you chain tight with that setup, a TAV is a Torq-A-Verter (Torque Converter). It uses a belt and a driver and driven to chain to wheel setup. It allows for good top end speed and great acceleration, it is a CVT.
Also, if you don't have a Band brake setup yet, I might have one for sale pretty soon for cheap.
