Leave the vent frame attached to the stainless as that only needs polishing, the potmetal outer A frame is attached by being peened over on the potmetal studs located inside the vent frame that attaches to it, grind the heads off of just the ones peened over, there's some addition studs that are not peened, use these to reassemble the framework back together after plating and polishing, hope your having the vent glass runner and handles done at this time also...


If the peening studs are in bad shape, or short, have the plater rebuild them before plating, otherwise your SOL afterwards
