I would certainly like to do some performance measurement on my as-yet undone upgrade on my Shopsmith DC-3300. Measuring motor current is no problemo. But I would love to measure airflow in a reasonably accurate and consistent fashion using inexpensive instruments. Rockler just put out a video showing measurements being taken on the new Laguna CFlux1 (the video is on YouTube):

(put a link in but don't know if it will stay put - if not, just go to YouTube and for Laguna CFLUX1)
which shows the gentleman measuring flow and velocity using a probe (hotwire anemometer??) in a long tube connected to the intake. That looks very do-able IF there is a low cost air speed meter available.
So any ideas, suggestions, etc?? Thanks
