Cutting Coil Springs - Eaton Detroit Spring
If these long-time Detroit spring guys don't know springs, who the hell does?
NOW... since they are doing bidness commercially, they are exposed to liability, which makes them play it super-safe to limit exposure. Not only that, they are in bidness to sell springs (I'm not sure why they put out the truth about home cutting them... maybe they are just that honest?) I'm not in the biz, but even if I was, I stand by my heat-reshaping of the spring seat. Think of it, they state that heating above 400deg = annealing, and annealing = steel too soft to
support the vehicle. Well look at that last coil on the square ended spring- that last coil is basically sitting there and it ain't flexing... if it is flexing, it's only a wee percentage as much as the coil above it and the others above that. All it has to be is strong enough to keep the spring seated squarely, not bear the weight of the vehicle for the entirety of that last coil.
