Atlas lathe parts manual pdf#
While I was at it, I took the time to measure and make drawings of some of the parts, since I may replace the dial with a larger version sometime in the future.įor a downloadable PDF of the drawings, looking under References/Manuals and Drawings below. The dial on the tool slide was badly tarnished and difficult to read, so I decided to remove it so I could clean it properly. A close inspection of the ends of the plates shows what I believe are manufacturing tool marks where they finished to length. It can't be seen from the photo, but with the jaws closed the ends of the face plates are not aligned with each other. As can be seen, they have been chewed up a bit (along with the movable vise jaw), presumably by a cutting tool mishap.
Here is the vise with the original face plates. I do not believe the "originals" were hardened either I tested the originals with a set of hardness testing files and found them to be less than HRC40 in hardness. I made my replacement plates from steel plate I had on hand - not hardened. The catalog drawing shows the plates as being even with the vise jaws on all sides on my vise this was not the case, with the plates being slightly oversize on the ends. The drawing is what I would consider the "minimal size" for the plates I intend to make my replacements slightly oversize. Here is a drawing of the vise jaw face plates showing relevant measurements: Ī few comments on the drawing and face plates: Although the vise is original, I have no way of knowing if the face plates were replaced or not at some time however, for the purposes of replacement I am going to assume they are original and use them as models for making new ones. In the vise parts list the jaw face plates are referred to as "jaw lining". As it looks identical to the "S7-91X Vise Assembly" shown in the manual, I believe this to be the case. When I purchased my shaper, I was told the vise was original to the machine. This is likely going to lead to additional repairs, which I will list here and detail below. Started taking some parts off for inspection, and also to measure in order to make 3D CAD drawings. More cleaning and fine tuning found a few more things that need attention. * Thought there was a bushing missing (part S7-80) but it is in place not sure if the screw and washer are original. * The toggle switch (part 41-44A) does not appear to be original, and does not fit well I may replace it. * The slot for the T-nut (part S7-30) on the "Disc and gear" (part S7-68A) had burrs on it, preventing the T-nut from sliding easily. I suspect this was done to align the large pulley with the small pulley on the motor shaft. * The large motor pulley on the countershaft (part S7-124) is reversed. Vise support pillar is frozen in place - need to loosen it up
Replace both belts (maybe - not sure this is really necessary yet) Fix motor belt drive bracket (bent out of shape - probably part of the reason the pulley was rubbing) Fix motor drive belt guard - the pulley rubbed against the inside of the guard and wore a small hole in it. Replace missing set screw on motor pulley Additional note: After looking at more information on the Atlas 7B, the crank handle appears to be the original size (not shortened), so my handle is probably just a repaired break.Īfter spending a day cleaning up the shaper and partially dis-assembling it, here are nine things I need/want to fix: Note that the crank handle has been braised either it broke at some point and was repaired, or it was purposely shortened (one of the lower crank points is very low on the machine).
