Theres also this guy who apparently makes pretty decent purging heatsinks
I ran into rob quirk at regents like 2 months ago and couldnt help but quiz him about a few things. Hes just transitioning to tig. He had bought heatsinks from this ebay guy and really rated them. And much cheaper than buying sputnik or other ones.

yeah, i made some really beefy ally ones for the headtube. Which made a difference on this frame as the HAZ is smaller than frames in the past. i want to purge the next frame so gonna have to do some fiddling to get them purgable :)
