I don't know if I could find him again. There is/was a guy in OH north of Columbus going towards Dayton, he bought up all their inventory. He had truckloads of Drill press, lathe and other Delta machinery. I found an ad on the vintage machinery forum. Someone posted it for him. He only did things old school via phone and snail mail. This was before Covid. I called him asked for a part on my 1942 DP that was cast Aluminum part. He said he had one and asked if I needed anything else. He ended up sending me the correct part and a bunch of other drills and bearing that fit in a USPS flat rate box. I sent him a check after I received it.
He sounded like a great older gentlemen that was retired and just wanted some company. I hope he is still around. I'll look but I'm not sure I could find the post again. I did find the part I was looking for on Ebay but they wanted way more than I paid. Supply and demand.....
