glass scales for atlas 12" lathe #3986
|
hi im in a position where i can purchase a 2 axes dro for my lathe..........its on ebay for less than 200.00.....the person selling it has good feedback so im not worried about that......i just need to know what length of scales i need for the bed and the cross slide ......they are listed in mm and im not sure how long i should get ......i measured the cross slide its 10" long and the bed roughly is 50 1/2 ...i know i wouldn't need them all the way end to end....im also considering if i want to put a taper attachment on my lathe if that would cause a problem ? the x axes im assuming is the travel down the bed length ways and the cross slide being x .....on the cross slide whether to mount it to the front or to the rear of the cross slide .....any help with this would be much appreciated .............tia ............Eric

I have a 12” Craftsman Commercial. I have IGaging dro , used a 12” and a 36” on mine. I have the Aluminum rails that are actually 6” longer than the given size to compensate for the 3” pickup. 12” is 18”, 36” is 42” . Nice thing with the Alum. Is you cut to fit. On my 3rd set of these ( 2 lathes and 1 mini mill ) and have no problems. Very accurate and work well. Bought on EBay Taylor Tools in Columbia,Mo.

开云体育X axis is cross slide, Z is carriage.? Atlas cross slides don't give much room for a side mounted scale.? Dave?

开云体育25.4 mm is an exact conversion to 1 inch. .03937" is really close to one millimeter unless you go very long! Dave?

I've thought about a DRO on my 12x36 and on my South Bend 9A. Where I really want one is on my South Bend 16 but there is one small, maybe not so small issue.? The bed length is 144"? with 120" of carriage travel.? I imagine a glass scale for that lathe is going to cost out the wazoo. James On Thu, Feb 14, 2019 at 6:45 PM Dave Matticks <dpm100@...> wrote:

Everybody recommends magnetic scales because they can be cut to size. They come in aluminum and stainless steel. Steel is more expensive.

i have converted the measurements over before i posted this thread .....the seller offers 100mm to like 1000mm .im thinking a 45 inch long one for the bed its the easy one but at the carriage the scale would have to sit on the two horns i guess that's what you would call them .....and the scales with the sliding part that does the measuring is 53mm or just a little over 2" tall .....that part of the carriage is roughly that thick......these lathes weren't designed for new technology lol ......i could geta short scale for the carriage and put it in between but i just wanna make sure im gonna have enough travel ......in the future im gonna machine my mla tee cross slide and have two tool post on it ........looking at cdco scales for a 12x36 lathe? they sell 13 inch and 45 inch in there kit ...ive looked at the igauging ones and they look nice and usable .....dto they plug into the wall ac ? they would probably be easier to mount ...but do you get bolt pattern and all the fancy stuff with them as you do with the regular type of dro .....ive welded for the last 25 years and my eyes are about shot ......i need to upgrade bad .................eric..... |

开云体育Eric, ? This post only applies to the last part of what I will call your second sentence – the proper name for what you referred to as Horns.? On a lathe, the major part that moves back and forth along the bed is pretty commonly called the carriage.? If the carriage is in two parts bolted together, the horizontal part that actually slides along the bed is most commonly called the saddle.? The vertical part that is attached to the front of the saddle casting is most commonly called the apron.? The most common names for the parts that you referred to as the horns are legs and arms.? There are four of them and they would be most commonly referred to as for example the right front leg, etc.? Unfortunately, different manufacturers are prone to using different names for some of these parts.? Only “carriage” and “apron” would appear to be pretty much universal. ? Robert Downs ?

开云体育No, 25.4 is exact since July of 1959..? Prior to that time, the US inch was about 0.000002” longer and the English inch was about 0.0000017” shorter.? That is 2 microinches and 1.7 microinches respectively. ? So to convert inches to millitetres multiply by 25.400000.? To convert millimeters to inches, divide by 25.400000.? Or you can divide or multiply by 0.0.93700787042.? Most people will find 25.4 easier to remember.? ? Robert Downs ? From: [email protected] [mailto:[email protected]] On Behalf Of Jody
