Welcome to the Group Sergey

?

OK so you have a Dalton that's great:-)? The Lot 4 started production early to mid 1914 and ran till the end of production in 1929.? Change gears are going to be a little hard to come by as I have sold off almost all the extra ones I had. Change gears are 20 pitch 14 1/2 degree pressure angle and you can get them from Boston gear or Browning gear but they are expensive.? In the past both Boston and Browning sold change gears with three different bore sizes but today they both only sell one bore size and don't remember right now what that is so you may have to bush any gear you purchase.? Let us know what gears you do have and I will see if I have any left that you could use.? I do have a few Boston gears that are direct replacements.

?

I also have some replica replacement bolts so again let me know what size and length you need and will see what I have left.? Bolts and other fasteners are standard size the only thing different is the shape and size of the hex head.? Dalton made there own? bolts and screws.

?

As for the cross slide extension casting for attaching the taper attachment slider to the cross slide you will? have to make one as almost all the taper attachments we know of that part is missing.? I have three taper attachments and only one original connector casting.? Will post a picture of what it looks like.

?

As for literature check out Lathes UK on the internet as Tony Griffith has some information and history on his site.? Oh and I wrote all the Dalton history for Tony about 20 years ago.? I also have a collection of literature on the Daltons but its just sales literature nothing in the way of any manuals have ever been found.? I also have the only stock of replacement parts but over the last 20 years most of the needed parts are gone.? Let me know any specific part and will see what I have.? I have a number of Lot 4 parts lathes. Understand that Dalton lathe parts usually don't interchange from one lathe to another as they were basically hand built so things like aprons and a few other parts just don't interchange from one lathe to another.

?

As to finish on original Dalton lathes they were coated with Japanning and did not survive very well.? So if your lathe is in original finish it will be japanning not really paint.? Japanning was two parts pure gum turpentine two parts boiled linseed oil and one part powdered asphalt.? It was brushed on individual parts then the parts were baked three times with the last time at near 400 degrees.? So if you have ever seen a black Singer Sawing machine Singer was a master at Japanning. The finish did not hold up will with UV and oil soaked badly.? The color is a semi gloss black and most of us have used semi gloss black Rustolium paint on our Daltons.? I have restored two Daltons using powder coat that turns out to be as close to the original finish as I have ever found.? I used 65% gloss black powder.

?

The picture is of a Lot 6 Dalton but all lot numbers used the same taper attachment and link casting.? Also all Daltons used the same size T slot in the compound for the tool post and also all Daltons from the Lot 4 to the Dalton 9 the distance from the top of the compound to the spindle center is the same so all Daltons used the same tool post. If you go to a modern tool post the OXA size quick change tool post is the best size.? As you get your lathe running we can talk more about what tool holders and insert tooling to use
