parts for the blower

I saw a Dewalt nozzle, part# N665136, which claims to add a lot of speed to their leaf blowers. I haven't really tested this one yet, but it should increase speed while decreasing air-flow.
The 5/8 thread adapter is a tight fit on the grinder thread. I needed pliers to screw it on there.
