I presume the gorgeous Craftsman metal lathe belongs to darus67
. I'm quite smitten with it, and look forward to getting to know it better.
I haven't turned metal on a lathe since high school, but I've been reading quite a bit about general theory as well as the Craftsman 101 in particular. I cleaned up the lathe a bit and checked through the various bits and pieces to see what parts it has. I'd love to get some practice in on a non-CNC lathe and outfit the Craftsman with a few more toys and goodies. This thread is where I'll dump useful info and reference material. I suppose I'm looking for the blessing of the owner to tinker a bit and get the machine properly lubricated and adjusted.
Here is some nice reference material and photos about this series of lathes: http://www.lathes.co.uk/craftsman/page5.html http://www.lathes.co.uk/craftsman/page7.html
Here are some repairs/adjustments that I think the lathe could benefit from:a new belt
The belt from the motor to the jack shaft is fine, but the main drive belt looks ready to give up the ghost any day. It appears to be a big job to take the headstock and backgears apart far enough to get a new belt in. Fortunately, they make modular belts that both circumvent this issue and also supposedly run quieter/smoother than a traditional V belt. I believe this is a 3/8" belt (of undetermined length), and a suitable link-style replacement belt appears to be about $25 from McMaster-Carr. I plan to measure it up and order something sometime soon.a new/different power switch
I noticed that the motor-mounted power switch is kind of spooky. It's open for the majority of the switch throw, only closing at the very far end, and sometimes you need to press on it a little to make a reliable connection. The location requires reaching over the headstock with your left hand to shut it off. It's also near plenty of finger-grabbing belts and pulleys; a poor place to reach in a hurry when something goes wrong. I propose a good old fashioned light switch in a handy-box (or a nice push/pull machine switch if someone knows where to find one) mounted to the bench front and center. A dedicated extension cord from the neighboring drill press bench to the lathe area would be super handy, too.disassembly/cleaning/lubrication/adjustment
Mainly of the carriage and the compound rest. Both axes of the rest turn pretty hard, and the main carriage sliding on the ways moves pretty easily. It would be a good idea to carefully disassemble each set of ways and gibs to clean off the decades-old oil and re-adjust for the best combination of free movement and precision. This is not rocket science, but is no small task, and I would definitely want the permission of the owner.
Here is the beginnings of my personal wish list of accessories:three-jaw chuck
The four-jaw chuck on the lathe is perfect for rough work, but it's very difficult to mount an existing turned part precisely on center without a long trial-and-error process. Three-jaw chucks are designed to automatically center a cylindrical object with little to no fuss. Note that they are more delicate and sensitive to abuse than their four-jawed bretheren, being precisely machined to align perfectly every time. They shouldn't be used for rough work, but hey, that's exactly what that four-jaw is for.tailstock chuck
All that is needed is the correct combination of adapter(s) and/or chuck(s) to allow a Jacobs-style chuck to be mounted in the tailstock. This would allow drill bits, countersinks, etc. to be precisely guided into the end of a workpiece by the tailstock ram to make hollow or cupped parts. In the toolbox, there is a morse-to-threaded adapter and a very small matching keyless chuck that does not want to operate (rusted/dented). A new inexpensive chuck that matches the threading on the threaded adapter should do the trick.boring bar(s)
I'm pretty sure this can be easily made in-house. It's a long tool holder that can reach inside the end of a cup-shaped opening to precisely face the inner surface. I've got one project in particular that will require me to make or improvise some kind of small boring bar.dial indicator mount/arm/thing
There's a nice Mitutoyo dial indicator floating around with the lathe stuff, but I don't see any tooling to mount it to the lathe for measurements or setup. This kind of thing can be purchased, but I bet I can make something very functional from hardwood. This is the official way to center something in a four-jaw chuck. In my experimenting thus far, I've been grazing my workpiece with a pencil to see if it's fairly centered based on where the mark is/isn't. Ghetto.more cutting tools
There are a whole bunch of hand-ground cutters in various states of sharpness and correctness piled in a box on the lathe bench. I'm planning to study up on grinding such tools by hand. With appropriate permission, I'd love to re-grind the worst of the tools into more useful shapes with proper angles and sharpness.
