There's an old Dayton-branded 15" VS drill press for sale in my area. I paid $20 for an option on it for a week. I called Grainger and they said they have nothing on it now but that it was made by Wilton, they couldn't tell me when.
There was no power in the shed where I looked at it. The top sheet metal was off the head, exposing the VS belt and sheaves to the sky. They looked OK. There is light rust on the column, table, and on the outer skin of the chuck, which apparently is a #33 taper.
This is an estate sale situation. The former owner worked at Stanford all his life. The motor has a tachometer which is connected and the wire goes into a Rube Goldberg box hung on the side of the machine. There's some kind of circuit board in there, and a pot shaft sticking out the front and a 3-way toggle sticking out the side. I think the toggle is FWD/OFF/REV and I imagine the electronics on the side were for some kind of RPM display.
The spindle seems to spin freely, and the quill goes up and down fine. It has 6" of quill travel and a solid quill clamp as well.
I'm going to haul a trailer back out there in a few days and power it up and if it seems to work OK, haul it home.
Anyone have any info on this machine? Dayton model 3Z327. There's one on ebay, item no. 300246389591.
