Although you can do good work on them and a lot pf people have them, if you are part way into a job and suddenly discover that you need to change the table to quill distance, there is nothing to keep the quill from moving from side to side as you raise or lower the head. If you decide to go with a small vertical mill, I would avoid any of the round column drill-mills where you change the quill to table distance by raising or lowering the head. You can't cut two or more parallel slots with a vertical. On the other hand, you can't put a horizontal head on any vertical mill I ever saw. And hole drilling and tapping operations won't be as convenient on a horizontal. When it comes to things you can do on one but not the other, you can't cut a diagonal slot with an endmill (vertical ends to the slot) in a very long part on a horizontal because the part would have to stick down through the table. But most operations will be more efficiently done on one or the other.
Subject to size constraints, pretty much any operation that can be done on one can be done on the other. If you decide to get a mill first, ignoring $100K NC work centers, there are two basic types, horizontal and vertical. They were produced from sometime in 1967 to. Both are in the final model group built by Atlas. The machine in the photo that you posted was a 3986. If I had read your post at the beginning, I would have recommended you grab $1100 cash and beat feet over there and offer him $800 for starters (no point in not trying!). Sorry I was tied up with income tax (and now sales tax) when this thread started and didn't log into the HM site for several days. I fact I sent him all the information that I had to him awhile back as he could make better use of it. He has a 3996, I believe and is very knowledgable about these lathes. Maybe Robert also known here as wa5cab, might see your posting and have a better idea of what to do. In my area where automotive and aviation is/was a major part of industry, lathes are common, but out in Saskatoon, they are harder to come by so in his case he hit a motherlode as any parts he did not need he could resell to others in the area. A second slide, extra parts and gears that were either used or new from Clausings for another $200. I then sold the remaining parts that the buyer did not want to a guy out in Saskatoon.
#ATLAS LATHE 12X36 FULL#
I sold my Atlas, not a 3996 - it was an older 10F24 for $600 complete with stand and full set of change gears for SAE and metric threads.
You do not need them all right at the beginning, but you will need them at some time. Then price out the missing components and think about it.Ĭhange gears? The QCGB covers the common threads but what about the odd threads that a couple of gears may allow you to change things up?Īlot of the other stuff that one does not think about cost as much or more than the lathe itself. I would get a list of the remaining parts that come with that lathe and compare to what SHOULD come with the lathe.
