happy to chat about, take advice, slag me off. what ever
i have spent a lot of time grinding tunston i was definently not as close on the Gusset welds as i could have been but mainly down to position. i do plan on redressing them welds later. i think i was between 1-2mm of the surface but will try and get a bit closer.regarding your welds, some (hopefully) constructive criticism: I suspect you aren't getting things as clean as they need to be for TIG to work well. I also suspect you're using a fairly long arc length.
IMO, for someone working on learning TIG, if you aren't dipping your electrode reasonably often your arc length is most likely too long.
Standard set up so no gas lense. Using a size 7 cup, around 10-12ft/h ( this is probably the problem area as I need a better regulator) filler rods are all cleaned off before use, rubbed down with scotch bright.In that case I'm surprised at all the oxidation on your welds. Are you running a gas lens? What size cup, what argon flow rate? Are you wiping your filler rod off too?
I've never cleaned filler with abrasive, I just use acetone on a paper towelStandard set up so no gas lense. Using a size 7 cup, around 10-12ft/h ( this is probably the problem area as I need a better regulator) filler rods are all cleaned off before use, rubbed down with scotch bright.

I have some lenses, just never used one. I'll give it a go. Cheers for the tipI've never cleaned filler with abrasive, I just use acetone on a paper towel
that's a little on the low side as far as flow rate goes but if your stickout isn't too far I doubt it's your problem, so I wonder what's going on.
I'd suggest a gas lens just so you can run more stickout and less gas flow - it'll save you money pretty quickly. a China/Amazon supply kit is fine but I'd recommend buying a name brand lens itself, one of the ones in my Amazon kit didn't work right (I think it was plugged up somehow). I got gas flow per the regulator but got tons of oxidation, switched to a different one and it works great.
No but I do now will read up and add more if required. Thanks very muchYou know that those subframe gussets are not the best design, right? For maximum strength they should be aligned to the sides of the tubes, and not welded along the central line. Best described in Tony Foale's articles, such as this one - https://motochassis.com/Articles/Frame.mod/KawaMods.htm :winko:
Not sure on colour yet, I know what I'm doing with the tank I'll work to out frame colour after. The front wheel and for lowers are a grey colour so may just stick with that or maybe go with a gun metal. Juries still out till it's mocked upI think you should keep the frame that lighter shade of blue. its nice.
