Well, I've had to take the lathe out of the shop and into town to an authorized service center for Delta lathes for repair and I'm worried about all of this. Since I purchased the lathe, Delta has been sold to another company and according to Internet postings about this, their customer service has really deteriorated. I looked around for replacement switches for the lathe but everyplace I checked had backorders for them. I hope the service center can either locate a replacement switch or find a comparable switch for it. They'll let me know in 10-14 days what will happen.
So it's in the hands of the specialists.
