Victory mc footboard-round 10-to powdercoat9-7-07 I delivered the mounts to the powdercoater, late am, today.http://www.weldingweb.com/attachment...1&d=1198362257Above are the mounts with the hangers installed and the high-temp silicone pull plugs, temporarily installed for this pic.The pull plugs will be installed and trimmed, after the bead blasting. The tapped holes which attach the forwardsaddle bag bars, are sealed with the hanger bolts, to prevent blast media from getting into the threads.The uncoated area behind the locking nut (not seen) that fixes the position of the hanger/grounding platewill not get powdercoated, it will get some touch-up enamel.     [The epoxy, heat-activated, powder is electrostatically applied to parts, which requires good grounding. This electrostatic ‘spraying’, allows the powder to be applied more uniformly and to an extent, go around corners, into corners, adhere to edges, etc. The baking (which is done at about 400?F, if aluminum, then melts the powder, which flows out and crosslinks, into an extremely durable, good looking finish. The extreme degree of spraying skill, required by liquid paint spraying isn’t required for powdercoating.]    The powdercoater will bead blast the mounts, Monday, then call me to look at them. If there’s any sanding marks that need further polishing, then that will be done. The bead blasting does a great job of covering all kinds of sins.     Following the bead blast, then the mounts will be primer powdercoated. Then, Dave gets another call to look at the parts, in particular the tiny, scattered porosity. Hopefully, just some sanding of this primer coat is all that will be required. Next is the top coating, with gloss black powdercoat.    I did more TIG welding and boiling out of the pores, this am, then finishing sanding and polishing. If, if I ever have to do more fine finishing, in blended surfaces, I’ll need to try out some more small 3M fiber-flex type abrasives. Any sanding over the parent casting surfaces needed to be done very gently, with minimum depth of cut, to avoid exposing even more porosity.    If the ‘show-side’ joints could have been ‘as welded’, I would have save 3 weeks of fiddling, and $300+ in abrasive finishing costs.*************Views of finished mounts in the fixturing, below. I took these pics, since the bare metal will show more detail than the gloss black for my Discovery Channel show ‘Bustin-Iron with Blackbird’.http://www.weldingweb.com/attachment...1&d=1198362429http://www.weldingweb.com/attachment...1&d=1198362491 Attached ImagesBlackbird
