Hi,

I'm new to the group. I've done virtually no machining since high school (over 40 years ago), but in the last year have acquired an Atlas 618, an identical Sears lathe with the milling attachment and a Levin lathe. The 618 was working before disassembly for moving. The Sears hadn't seen use in decades, though it still looks to be in good condition. I've got manuals for both and numerous accessories. The Levin hadn't seen use in some years and needs restoration. The Levin was bought by NASA in the early 60's and was used to make parts that went to the moon. I'm a software engineer by trade, but like projects at home. That's it, Don On 1/22/2019 5:17 AM, [email protected] Group Moderators wrote: Hello, |

Re: Dial Thumb Screws
开云体育Thanks guys for the advice.? My screws are brass so should not mark the screw.After doing some measuring last night on the compound, the dome bolt head holding the bearing end plate on, really limits the size of your thumb screw. The thumb screw will roughly need to be .250 OD and .150 thick. I'm almost out of brass stock, so I might just countersunk the holes in the end plate and put some countersunk socket head bolts in there.? Then use the thumb screw I have made already.? I will still probably need to turn the OD on the new thumbscrew down some from the 0.500 it is now. I would like to make some bigger dials but don't have an indexer or number stamps.? I guess I could rig something on the lathe.? But for now I have other projects I'm ready to start instead. Thanks for the inputs, Jody -------- Original message --------

Re: Little blast from the past
开云体育Now that sounds like a good size lathe! Now I prefer smaller work.? I do pretty often start with a 75lb piece and when I'm done it's reduced to maybe 12lbs!?
