I have a 4 1/2 year old Midi that developed bearing noise and note the lathe had not been heavily used. Since it was under warranty for 5 years, the WoodCraft dealer here in Norfolk, VA was able to get me a new set. I replaced the old bearings and could not feel or see a defect on them. I still had the same annoying whine with the new bearings. I replaced those with quality bearing from the supply house and problem solved. As noted on this forum previously, Delta parts for this lathe are not always available and such things as a switch are declared to be obsolete and there is no reference to any other source. Hopefully, the new owners will work harder to correct this serious deficiency. Robert Waddell
