Unimat SL1000 Upgrades

[@TheVintageEngineer]

Man I’m kinda jealous of the controller with the housing. Too bad I didn’t see that one before. As far as the Chuck, does the part that mounts to the spindle separate from the jaw holding part or is that the same piece? If it’s a separate piece you can mount the backing plate to the lathe and face it so that the mounting surface is tried up on the lathe (but from what I see it appears to be the same. Another thing, are the jaws in the right position? There stamps on each section and jaw? Like 1-3. When reversing the jaws on an real Unimat you have to swap I believe 1 and 3 and leave 2 in the same slot. If all that checks out you may have to grind the jaws in place. What you do is mount a Dremel tool somehow to the carriage and essentially grind the inside contact points of the teeth. Lathe running and grinding bit moving in and out of jaw area. One thing you have to watch out for is there is backlash in the jaws that gets taken up when a work piece is clamped (so the jaws are pushed outwards to take up the backlash). Need to figure a way to have good outward force on the jaws when grinding them. I think there are a few videos in this. Keith Rucker (vintage machinery) did one a couple years ago.

Thank you Anthony for explaining this to me. The back end of the chuck can be removed, I did cut that side too, but still not working. I was thinking that it could also be the inner threading. Maybe the company didn’t make the thread in a straight line. I haven’t tried with grinding bit yet, I’ll try that one too. Thanks again man, I appreciate it.

Reverse the jaws in that chuck and it should be good

[@VintageCraftsmanTools]

Hi. Thank you for your comment. Now I have a better chuck and works perfect. It’s an accurate lathe. Love it.

[@simonduff6309]

@@VintageCraftsmanTools great! Maybe can use the other one as a spare.

[@VintageCraftsmanTools]

Yes definitely.

Machines that are no longer produced, why are they being promoted???

[@VintageCraftsmanTools]

Thank you for asking and sorry to disappoint you. My answer would be, I only share how I disassemble my tools and what I do to do them in case of upgrade. Only in case if anyone ever was to do the same to their machines/tools, they would at least know what to expect. Unfortunately, there are no longer being made but for those who are enthusiastic and interested about these lathes, this video could be a bit interesting or useful as I hope. Thank you for commenting.

Why not ? Some of us like older machines over the newer ones. I also own a 1948 Atlas-Craftsman 12”.

[@jrkorman]

So should folks throw their '65 Mustangs in the dump because they're no longer being produced? I've got a 1941 Craftsman metal lathe as well as a 1969 Unimat. Should I trash these also? Is anyone making videos about them wrong?

[@VintageCraftsmanTools]

@@waydegutman7339 Sorry for my very late reply. I also have an Atlas Craftsman from 1938. A great lathe from back in the day.
