You want them to last, if you are using scrappy metal you are just practicing. Use a bit of scrap metal and test how good the mill works. Now that you have it all together, put it to the test. This will make a good milling operation for any cutter sizes up to 1/4 diameter. This is just a straight shaft mounted in bronze bushings with a flange at the front that mounts a 4 jaw chuck. I first made a spindle that mounted in an aluminum block that mounts in place of the milling vise. That is a vertical slide with a vise that mounts in place of the compound slide. For milling operations just tighten the slide adjustment screws on both the compound rest and the cross slide for milling operations. I have a 6' Atlas lathe with a milling attachment. This should give you a three way motion with the drill vise holding the work and the lathe chuck holding the mill end. The Logan lathe doesn't have the same type dovetail on the cross-slide, so I'm going to have to make some sort of adapter for it. I built a T-Nut and used the compound rest. On the Atlas lathe, the compound is removed, and the milling attachment fits over the dovetail on the cross-slide.It is locked to the cross-slide with two angled pins. lathe for milling out parts in the manifold of a model 4-cylinder gas engine. now bolt it all together and test it out. I installed the milling attachment from an Atlas 6 inch lathe on an Atlas 12 inch lathe. If you’re willing to trade your time that way, this really is what the milling attachment is designed for. Using that as a pattern do the same in the drill vise so it will bolt on to the compound rest. It is as shown and is an ATLAS NUMBER M6-501 MILLING ATTACHMENT for ATLAS 6 LATHES. Next drill four 10-32 holes int the compound rest on the top. This is a METAL WORKING LATHE MILLING ATTACHMENT.
Next you need to remove the tool post bolt out of the compound rest. Step 2 - Drilling the Angle Plateĭrill two hole patterns on the other face of the angle plate so the it will mount vertically far or near, with the opening of the vise at the center line of the lathe with the compound rest at the center of its travel. Remove the compound rest and using it as a pattern, drill a similar hole pattern in one face on the angle plate where it will mount there instead of the compound rest. Make sure it will rotate and clamp in any position.
