What are they?

Thanks Biagio. I'm not sure which page is page 3 but I have a metal cased B & D 1/2" drill. It was given to me a couple of years ago with a broken chuck. I replaced that and it still runs like a top, only slow and non reversible. I use it for mixing mortar, drywall compound etc. It has the power that my other drills lack. It comes from that era you talked about when B & D tools weren't a joke. I have one of their 7" angle grinders from the same era and it's a workhorse too. That may be why we didn't see some of the tools you mentioned. Ours were pretty good and would have been a lot cheaper.

Generally S4S 1" is still 3/4" finished but they can vary a bit. Back when you were using the electrichisel common practice was to saw the lumber and then let it air dry either completely or for a good while before going into a kiln. I think that wood was probably more stable that what we have now where it gets sawn and then into a kiln within a few days. Moisture content varies considerably depending on both where the lumber came off the log and where the lumber was in the kiln, that is top or bottom of a pile and inside or outside. It then goes to the planer and if the MC isn't stable then it can finish drying to a slightly smaller size after planing.

I would be interested in having it Biagio. I like old oddball tools. I have one hammer drill/drill combination that might run it. It's 2500 rpm in drill mode but I don't know if it will have enough torque. I saw sharpening instructions in the pdf so I can do that. Pm me with what you want for it and we'll exchange info. And thanks. BTW, did you ever see the thread where I posted pictures of something that looks like a chisel but isn't? No one has ever said they actually have seen one of positively knows what it is, including the staff at the local Lee Valley store. There are good pictures n post #17. I got it from a seller in the UK with 8 other tools that were chisels. https://www.routerforums.com/what/124025-chisel-2.html
