JP,
I don't believe it was a Douglas in the most recent incident.
When Tony tried to blow his thumb off, that was a Van-K on a Vega.
When Matthew tried to blow his hand off, that was a Tru-Roll on a Dunlop.
I don't plan to mount anymore 6" diameter wheels outside of a containment unit.
And I use a remote hose when mounting 5" diameter wheels (average about 30 a weekend)
I have had WMS and Van-K explode or implode on me in last 24 months.
Douglas has been the only one I have not had a issue with personally. I am sure I am on borrowed time.
Mike
