Hi gang, I almost forgot to ask if anyone needs any parts for their Daltons. The one on ebay is just an hour away, so I'm wondering what the parts situation is out there. Let me know if I should go

Good evening gentlemen, Well, it turns that at least some of the taper is due to the chuck jaws. I can fit a .002 feeler gage in between the jaws and the work. Sooo, anybody know if there are jaws

Thanks for the link Dave. My full time position is that of an an Optical Manufacturing Engineer for a leading Metrology company (Zygo Corp). We make some of the stuff NIST uses and we all use the

Hello Dave, I would bet the bar is flexing causing the taper. Larger diameter is preferred, such as 2", can even be pipe or tubing. The material behind the chuck shouldn't matter as long as it is

At the moment, the test bar diameter is .946. I'm using a piece of 12L14 steel since I only have a 5/8 piece of aluminum that's long enough. Last time I did this I started out with a 1" piece of

Hello Dave, What is the diameter of your test bar? R.T. :D

Good evening everyone, Anyone else get a kick out of the Complimentary Small Plastic Ruler Metrology? So I'm just up from checking the taper on the B-4. I'm smaller at the tailstock end by .006.

Morning folks! I was looking for federal micrometer spec's online this morning and found this. Very interesting reading,check it out--- Gotta go to work, check back later Dave

Yes Jim its a lot 5. The seller gave me a number off the end of the bed of 3213 but no Lot number. I sent a picture of the end of the bed and asked him to look again for a LOT number. I have not

Is the Dalton currently on ebay some sort of LOT 5? When I lightened up the pics, it looks like a worm drive apron. Jim

on the morfidit countershaft and maybe one of the back plates he calls a face plate would be usable. Other than the chucks there is nothing Dalton. I have not a clue as to what that cross

Ok, I'm back. Would you believe I can't find my test bar? I think It got misplaced and then used for something. Considering the meagre space I have for my toys, it's not that unbelievable. So, I'm

Ok guys, thanks for the response. Like Ron, at first I was thinking headstock or spindle alignment. But the more I think about it, what would cause that? I loosened the mounting bolts today (they

Hi gang, What I ended up with on the Dalton was about .001 taper in 5 1/4" towards the tailstock end. I checked this after a week and then after two and three weeks and it stayed there but I haven't

As to micrometers versus calipers. Well there is no contest here. A caliper is only accurate to maybe + or - .001 and that is the very best ones and in like new condition. A micrometer on the other

Hi Jim OK if your lathe is cutting smaller at the head stock than it is out in space your bed has a twist in it. Now this is figuring that the head stock is in correct alignment and or your spindle

Hi all Just a note about the Dalton on eBay that is located in NJ. This is a Lot 5 lathe with power feed to the saddle. (not cross slide) The lathe looks to be in original finish and not too bad

Morning Jim I do a lot of tapers by offsetting the tailstock. But since you are not using the tailstock and the taper gets smaller closer to the stock. My vote is that your headstock is slightly out

Morning Dave I find that Micrometers are more accurate than the calipers. I use both. When roughing in, I use Digital calipers because the measurements are done very quick. However when getting
