Karl:
So far, I've just been grinding the rounded profile back on (eyeballing
it) with a carbide burr in a high speed die grinder. Then comparing the
total thickness with a caliper (and re-grinding to get it closer!).
Well, I know it sounds a bit less accurate than the factory's profile
machining, but so far, it's worked GREAT and I'm a tad thrifty. I've
also been known to weld patches on mufflers (some of which lasted a
couple of years, making said time more productive than someof my hours!)
I've also heard that some Vanagon release forks had poor quality welds
and failed when almost new. does anyone have new ones, besides the
dealer? Or are they reasonably priced at the dealer?
