Fellow Lumberjock Jim Jakosh asked some valid questions concerning my DIY air filter. He asked about the clearance when turning a large bowl with the filter in place. So, this morning I measured the clearances, if any, between the end of the filter and the face of my 6” dia. faceplate and my four jaw chuck.
Taking the filter off, I measured 3/8” clearance between the end of the motor and the face of the faceplate. I measured 1 1/8” clearance with the four jaw chuck in place.
I took the filter to the table saw and reduced the depth from 4” to 2 1/2”
Installing the filter again, I now have about an 1/8” encroachment with the faceplate installed and about 1/2” clearance with the four jaw chuck in place.
This lathe has a 12” swing with the head stock in the ”Home” position so depending how I set up a 12” piece to be turned using the faceplate I may have to remove the filter. I should be OK using the four jaw chuck.
There were some questions about restricted airflow around the motor with the filter in place. The filter material I am using is manufactured by Flanders PrecisionAire. It is a washable and reusable material designed to reduce dust, pollen and lint. It is not a high micron count filter. As you can see it is a rather loose weave.
I don’t know whether or not the addition of the filter will be of any substantial benefit. I guess time will tell. I will keep you posted.
