?? Geoff's machine is loud simply because it's his punishment for
calling me on the phone and telling me to listen to the lack of noise
coming from his dust collector.

I checked the data info on the machine and not the motor this morning.
The motor on my KF7F is rated at 14.5a at 240v 60hz and 3400rpm at 50hz
it says 15a and 2760rpm. There are different pulleys and belts for 60
and 50hz that get the arbor speed up to around 4000-4600 rpm, not sure
of the figure.? I'm wondering if the 15amp figure is wrong and should
be 14a, since on the AD7-41 and the AF22 the amperage draw is higher at
60hz.
I know that on the regular AF22 Dust collector, motor noise became a
problem with the higher rpm at 60hz vs 50hz. On my AF22 the rotation at
60hz is 3360 vs 2780 at 50hz. The newer AF22LN has a 3kw motor and a
smaller diameter fan resulting in much lower noise.
?? I haven't noticed any noise problem on my KF7. Turn in on, and it
just gives that nice tone, a lot different from when I turn on the
unisaw.
?? As far as not needing the transporter unit with the mortiser, what
Phil Tamarkin failed to mention was that he also didn't need a forklift
to get his 3000lb BF5 off the truck. He just picked it up himself.
(Only kidding Phil)
?? The transporter does make things much easier with it attached to the
jointer planer. I could see where you may not need the transporter if
the mortiser was attached to the K7 or the KF7 machines. Here it may
not get in the way, especially if the joy stick was taken off.

John,

Are you running a 10" or 12" blade on your machine? I would imagine
that the dB levels specified by Felder for noise levels are measured
with the 10" (250 mm?)blades.
