Visited my Mom this past weekend to help go through my late father's tools.

Spent half a day sorting through machine tools for her.? Got some a few nice things for myself to round out my boxes, plus loads of inch-sized taps, dies, etc.

Anyhow, I've been going through the small bits and adding them to my existing stock.? Came across a few things and I either don't know what they are, or I'm not sure what their purpose is (ruler is for scale).? Any advice appreciated.

Have a couple of reamers with dedicated handles.? Were reamers commonly used by hand?? Doesn't seem a very accurate way to use them.



These reamers and counterbore or deburring tools have a square tapered shank.? What sort of tool would these go in?? Reminds me of something that would go in an auger.? Doesn't appear the shank is standardized.


Have a fair amount of gently tapered reamers with square shanks.? Just like the standard reamers I'm familiar with, but with a taper.? Most are so slightly tapered it's difficult to see without paying attention.

I'm familiar with more steeply tapered holes like for ball joints, but these are generally less than 1/2" and more often closer to 1/4" with a gentle taper that doesn't seem like it would be useful for something like a friction fit.? Is this maybe to make things like locating dowels easier to assemble?? If not, what's the common use (besides the obvious of making gently tapered holes)?
Re: Lot 4 Change Gear Plate & Casting New Part

In your situation I'd fabricate a steel banjo and blend the welds in so it would look identical to the original, a coat of paint will hide all evidence and you'll end up with a far stronger banjo than the original.

?That is, if you can't find an original replacement.

Just my 2 cents on it, but then I'm known to hate alumicrap.

Lot 4 Change Gear Plate & Casting New Part

Ebay Boy
 

after months of carefully chipping concrete and paint off the brass plate i’ve finally revealed the data. i’ve also made wax copies of the change gear banjo as mine is split. it’s shown superglued (so i could mould it) obviously an aluminium cast isn’t going to be as good but it’s the best i can achieve with the tools available.?

I’m surprised to find metric threading data! it’s the very plate that was on my lathes side door.?

i can’t imagine it’s original? Dennis mentioned a few years ago my Lot 4 has a 24 lead
maybe someone can look at brass plate or the text i’ve copied from it and let me know if it’s correct for my lathe.?

I had a Doctor in Hillsboro years ago that had a really nice Dalton adding machine of some kind on display in his waiting room. According to Gay Howards biography of Hubert Dalton he? never owned a business machine mfg. company.? He did have a hand tool company and also a company that grew Flowers. Growing flowers was one of Hubert’s hobbies in later years when he was in Hawaii he raised flowers there as he could grow them year around. I actually drove by his estate in Hawaii but did not know it at the time I was there.?? Dennis

Re: Did you guys know

"After complex business dealings, including intervention from other adding machine manufacturers, James L. Dalton (1866-1926) acquired exclusive rights to manufacture machines under the Hopkins patents"

?Says "James L. Dalton (1866-1926) acquired exclusive right to manufacture machines under the Hopkins patents"
?
?But Dalton's first name was Hubert, " (1866--1952) was English by birth and the first born of eleven children." (From Lathes.Uk) Probably a coincidence that Hubert and James had the same birth year though. I know Hubert had many other businesses but office machines don't seem to be part of the array.

OK as to chucks for your 1 ? - 12 Dalton spindle.? I have found that there are some very good buys on chucks for 6 inch? Atlas lathe.? They come in two sizes.? The older 1 inch 8 for the original plain bearing spindle and 1 – 10 for the later roller bearing spindles.? Both are usable on the Dalton.? These chucks if original Atlas are direct mount without a back plate.? The rear hub is large enough that you can machine a new thread in the chuck to fit your Dalton spindle.? Now I know this takes another lathe to do so but that’s why I have always had two lathesJ.? This last week I watched two almost brand new chucks sell on eBay.? The 4 inch three jaw sold for $110 and the 4 inch four jaw sold for $125 if I remember correctly.? Both were well worth the price they sold for as they were really in fine shape and came in their original box with instructions and wrench.? If one of you guys come up with one of these chucks any machine shop can fit it to your spindle.? Would require for you to remove your spindle but that’s an easy job on a Dalton.? Just some information that may help one of you guys find a good three and four jaw chuck for your lathes.? Remember Dalton provided a 4 inch three jaw and a 5 inch four jaw with the lathes when purchased new.? I don’t recommend any larger chucks than these sizes for the Lot 3 4 and 5 lathes.? Now for you guys with a Dalton Lot 6 or a Dalton 9 that spindle is the 1 7/8 – 8.? This spindle size is the same as SB used on early heavy ten lathes as well as 1930’s vintage 13 inch. These chucks show up every now and then and you can also find new back plates for this size spindle.? Dennis

That's exactly right. For fit you use the dovetail sides on the other mating part, blue them up and scrape to match, but only on the side without the gib which has the set screws, as the gib (Talking only about straight gibs here, the kind adjusted using set screws, not tapered gib types) will conform to the mating dovetail automatically as the set screws are adjusted.

Re: New to me Lot 3 needs a cross slide part

 

Wow, thank you for all the background and advice. I’m very excited to have such a unique machine. Much better than the new import I was considering!

Dennis, I’m away for the weekend but when I return I will measure the center height and take some more pictures.

Glen, I would love to try to fabricate a new part and scrape it as you say. Scraping is something I find interesting but I’ve never had a reason to try it. That said I’m going to run it and let it’s performance be my guide. I may?find out it works just fine for what I need, as I imagine the last owner did. This lathe has obviously been well used and maintained and the repair doesn’t look new. It came to me well oiled with a modern quick change tool post, lots of tooling, and covered in chips.

Your point about making a drawing is well taken. How do you measure across the dovetails? I’m guessing you put gauge pins against them and measure across the pins, sort of like how threads are measured?

If I do take on making a new part I will definitely come up with a different way to clamp it than the old part. The hole where the clamping bolt comes through is wallowed out and so close to the surface that it’s cracking there too. Not a good design, although it did last 100+ years.

Thanks again!

I have not worked on my Select for a long time Glen.? You may end up with it one dayJ? As to the lathe it’s a Hodge podge of copied parts.? As you said the saddle cross slide and compound slide are pure South Bend. ?In fact a South Bend cross slide fits the Select saddle just fine. ?The apron is a morfidite. ?Was originally a C style apron that? they made a feeble attempt at making a power cross slide out of it.? Failed miserably. The quick change gear box is pure Boxford as is the tail stock.? Head stock is very much like later model Hercus out of Australia.? The back gears are metric but almost identical to South Bend.? In fact if you recall my back gears were all laying down in the bottom of the head stock.? Least all the teeth wereL? I altered the back gear shaft by turning down from metric to inch and now a SB back gear fits perfectly.? I also made a new bull gear for it but its South bend on the outside Select on the inside.? Well it fits the Select spindle.? I made a bronze gear that is bolted to the original cone V belt pulley on the spindle and its South Bend.??? Not sure why I went to all this trouble and should have done like I did the Jet lathe? at the Florence shop and just made it a serpentine belt two step drive and run it with a inverter.? The end gears are in fact 18 pitch South bend as is the gear on the end of the spindle.? My lathe was missing the shifter so I installed a South Bend and it fit perfectly.? So to say the lathe is a morfidite would be true.? It’s a combination of four or five different lathes as well as some metric and some inch especially in the gears. ?I think mine is an early version as the later ones are a bit different. Not sure I have seen any pictures of yours Glen so not sure if it’s like mine or not.?? I am still toying with the idea of altering were the threading lead screw is mounted and use a SB saddle and power feed apron.? I have both in really nice shape. Oh and the SB saddle fits the Select bed.? Just like the Boxford Saddle cross slide and compound I installed on a SB lathe that is now in Michigan. Sure wish our email services would talk to each other.? Sorry guys I know this is off list but it’s the only way I can email Glen as well as Bart.?

Interesting Glen as I have you listed in the registry owning a Lot 3.? Hmmmmmmm.? I have two nice pieces of cast iron.? One is 80,000 PSI ductile iron.? Glen the way the lot 2 and this lot 3 compound works is the cross slide has a spud about 1 ? of an inch in diameter that’s about 5/8 tall.? Dimensions are just a guess as I am working from my memoir bankJ? I have seen two different ways that the compound was secured to the spud on the cross slide.? One as we see in Jason’s lathe and the other where there is a separate part that is held to the side of the compound casting with two bolts.? This version clamps the fee piece to the spud.? In Jason’s and others like it there is a single bolt that draws the internal clamp against the spud on the cross slide.? The fellow up in Canada that has the third prototype 10 ? inch as well as Mitch Nash’s that has the only complete 10 ? inch Dalton both have a compound that is secured with the two bolt clamp plate on the side of the compound top casting. Will see if I have a picture of Mitch’s. As? you can see Glen? there is nothing to draw the compound down tight to the cross side like SB and Atlas did. As there? is no angle to the spud its straight sided.? I can see why Dalton did not continue with this design.??? I think if I were to make one of these compounds I would for sure put an upside angle on the spud and a matching angle on the top casting clamp so it would draw the compound down tight to the cross slide.? Think you would agree Glen.?? Dennis

So very good to see you on here Dennis! Dan and I were wondering where you have been the other day. The lathe I have is a lot 4, as common as rocks (kidding, but relative to this one).
?If I were Jason I'd buy some durabar or whatever ductile continuous cast iron his steel seller can provide, and make a new compound base and compound from that. No need for a surface grinder, just get the dovetails close
interference and scrape it. Jason, if you do that and don't want to learn to scrape I'd scrape the dovetails to fit for you if you send them to me. You should have enough there to get all the dimensions.

?I highly suggest you start by making a detailed cad drawing first as that has saved many machinists untold millions of scrapped parts as it will help you plan your operations and avoid snap judgements too late as you might have doing it as you go through the machining process without drawings.
?The compound base in the photos has a very unusual compound receptacle hole and or locking system (Third photo from the top) and I can't understand how it works by looking at it. I also don't know how the square? inside corners could be machined from solid, and assume they were cast originally. You could use an EDM sinker I guess, but the cost would be very high short of getting it done by a donation time by someone with a sinker.
?I assume also from the photo that the piece in that hole is loose and is how the base is locked to the cross slide, is that right? If it is perhaps you could save making that part and use it over in the new base.
?Perhaps you could mill the internal internal features where that fits with a rotary table and successively smaller endmills to form the inside corners, tricky work but doable with patience.
?Is the project worthy of all that work? YES!
Glen
