Re: Lot 4 No. 1770 in Germany

As to tapers the spindle is a number 3 Morris and the tail stock is a? number 2 Morris taper.? The spindle thread is a 1 1/4- 12.? Some people have had success in using a ER 32 collet fixture with a number 3 morris taper shank. You have found the first Dalton seen in Germany.? There was one in Holland as well as a number of them in?England. Think there was one found in Italy also but not sure about that.? As to using?a taper shank collet fixture in the spindle it would be advised that the taper be drilled and tapped on the small? end so a draw bar can be used to keep it? secured in the spindle. As to our question about a metric thread chart, yes we have?seen a couple and I think one of my Daltons has one.? As to bed wear, yes we see some but Daltons for some reason do not wear the bed badly.? Test.? move the carriage?close to the spindle then lift up and down on the hand wheel and note how much the saddle lifts off the bed.? Then do the same thing with the saddle at the tailstock end and see what you get there.? It will be different I can assure you of that and with use of feeler gages you can determine how much wear you have. As to the spindle bearings if the spindle is tight and no more than .001 up and down play when you lift the spindle you're in really good shape.? Also if it's more than that there are ways of tightening up the fit of the spindle to the bearings.? As to change gears a set consists of 15 change gears If you are missing any give us a list of what you do have and we can tell you what is missing if any. The most maddening thing about a Dalton is the very small dial rings on the cross slide and compound slide.? They are .004 per graduation and that makes working to close tolerances?difficult. Feel free to ask any questions if I can't answer them there will be someone in the group that can. Dennis?

A Dalton Lot 4 , No.1770 is currently offered on a craigs list equivalent in germany and i am thinking about buying it as my first lathe for my small hobby shop.?
I have a few questions that i want to clear before buying it, because i guess spare parts are even rarer in europa than in the US....
?
1) the spindle bearings seem quite tight. it takes some force to turn the spindle, at least it is definetly not turbing freely. when looking from the top, i am not sure if the babbits seam to have a crack in the middle, right were the path for the oil should be, going along the spindle axes.? would you ignore it and use it? and is there any way to replace the babbit? 2) how likely is it that the bed is worn out? when moving the carriage along the bed, it felt relatively consistent, not too loose, not too tight (but there is some dirt that might affect that) 3) is there a metric thread chart for the lot 4 lathes? since i am in germany i will only use metric threads, so this is quite important to me. i have found this foto, but i am not sure if it applies the the Lot4 lathe.... /g/DaltonLathes/photo/77634/917154?p=Created%2C%2C%2C20%2C2%2C0%2C04) from what i have read, the spindle should have an Mt2 taper internally, but some other variants have been found. Is there any way to confirm the Mt2 Taper on the lathe that i looked at, everything was pretty dirty in there, so no way to be sure. And did anyone use MT2 collets directly in the spindle? like these for example: last / 5) from your experience, if the parts that i want to make fit in the lathe, is there any reason you can think of, that would make the dalton lot 4 a bad choice for a small hobby shop? has anyone machined any stainless steel on it?? its such a cute little machine, that would perfectly fit in the tiny space that i have available. but i still have to try to stay objective about what it can do, and what it might not be able to do (or due to its condition and age cannot do any more) Kind regards Philipp
