Guenther’s reply may have seemed harsh, but I don’t think he was
far off target.
I’d have instead said that any decent machinist - or anyone
with experience running one of these light lathes - will already
know how to grind the tools to cut the pulley grooves. Because
the key word here is tools - not tool.
Trying to turn grooves for normal sized V belts on lathes
like these doesn’t work very well with form tools. ?Instead, you
need several different tools - the ones you use every day. ?A
parting tool to cut the depth of the groove, and to cut the
bottom to width. ?A facing tool to cut the left side of the
groove, with the compound feeding at the proper angle. ?And then
the mirror image of that facing tool to cut the right side of
the groove, with the compound set the other way. ?No pics should
be needed.
Not only would a form tool make no sense because of the
likelihood of chatter, but you’d need different form tools for
each pulley diameter. ?The angles are different for each
diameter.

Re: Need Pulley for Craftsman Speed-Reducing Attachment
Normal facing or turning tool is fine. ?Nothing at all special about the angles, as you’ll likely have to rotate your tool holder anyway. ?You may have to grind away some of the backside of the cutter to get clearance.
This is an example of where a lantern toolpost with a small bit held in an Armstrong tool holder really shines. ?A 1/4” or 5/16” bit should get right to the bottom of a pulley groove without needing to grind it narrower.
As to form tools, there are too many variables to give any guidance on what maximum width of cut you might take. ?Horsepower is only part of it, and in low back gear you’d have a tough time stalling the motor. ?Chatter is the big concern. ?Different materials, holding methods, cutting fluid, cutter sharpness all come into play along with speed. ?About all you can do is try something to see if it works.

Re: Need Pulley for Craftsman Speed-Reducing Attachment
Thanks to all for the info on the types, sizes, & locations for aluminum (& Cast Iron) to do the job.? It will be an interesting project.
John WIlshusen – Thank you very much for the pdf!? Just the kind of thing I need.
Guenther Paul – (And the others after him who responded to the tool grinding statement) Unfortunately I am new to machining.? I have made & ground 2 or 3 of my common facing & parting tools.? They have worked out good.? But, I am lacking in knowledge of grinding different tools, particularly form tools.? Not to mention that I am unsure how large a surface cutting area I can safely use on my lathe with a form tool? (Craftsman 12” #101.07403)? Seems like a can easily get my lathe to bog if hogging out too much metal at once.? Then gratefully jmartin957 comes along & adds that I should be using facing & parting tools for the pulley job.? I kind of understand that, but it leads to more questions.
1) Any specific suggestions on good YouTube videos or other instructional documentation on cutting all types of tools?? I have looked at many.? Some make sense, some not.
2) jmartin957, are you just saying that say the normal facing (left or right) tool is used, just ground at much different angles to accommodate the area to which you need access?
3) I am also specifically interested in any knowledge of what should just not be attempted on my particular lathe?? Like form tools.? Example would be let’s say a 90 degree form tool.? One where it would cut a full 90 degrees or ? of a ball.? Not talking this project, but others.? Instinctively guess that something that radical would be way too much for my lathe.? Would a larger ? or 1 HP motor help or would that just as likely break something as help?? My lathe currently has what I believe to be the original ? HP motor.
I cannot apprentice with anyone so as to watch them and learn.? So I am stuck with finding what I can on the internet, which as you know is not always correct information…………
I know this is old hat to most, but important to me.? I have the luxury of being old (retired) and in no hurry.? So, while I am not trying to learn the trade for pay, I am doing something better.? Learning because I just want to and enjoy it…………..

Re: Need Pulley for Craftsman Speed-Reducing Attachment
My point, exactly, was that most of us are not professional machinists. Saying that you need to grind multiple tools to cut the profiles necessary would be useful information, though not sufficient. OP asked for pics of the necessary tool. So it is pretty obvious to me that he is, in fact, clueless, and trying to educate himself. What he got was snark, and not at all helpful.?
This hobby needs more people to keep it alive. It isn't intended strictly for crusty old professionals. I'm not a professional, either, but I'm taking a class to become one. And you know what? They haven't taught me how to cut a pulley in my class, and won't. It's not in the curriculum. They don't teach making gears, either. Professionals buy those things now. They don't make their own. Pretty much anyone MAKING a pulley or gear is an amateur, now. The info is available if you know where to look, but it's buried in old books and magazines and the fossilized brains of old machinists. It's hard to dig out because most of those guys have forgotten how they learned. Someone showed them, back in the mists of time.
Besides, GP is notorious for that.?

Guenther’s reply may have seemed harsh, but I don’t think he was far off target.
I’d have instead said that any decent machinist - or anyone with experience running one of these light lathes - will already know how to grind the tools to cut the pulley grooves. Because the key word here is tools - not tool.
Trying to turn grooves for normal sized V belts on lathes like these doesn’t work very well with form tools. ?Instead, you need several different tools - the ones you use every day. ?A parting tool to cut the depth of the groove, and to cut the bottom to width. ?A facing tool to cut the left side of the groove, with the compound feeding at the proper angle. ?And then the mirror image of that facing tool to cut the right side of the groove, with the compound set the other way. ?No pics should be needed.
Not only would a form tool make no sense because of the likelihood of chatter, but you’d need different form tools for each pulley diameter. ?The angles are different for each diameter.

John, Nice article! Procedure look good, I'd use different tooling but same idea. Not going to make one for this episode but I have made a pulley or 2 in the past. Trued up a couple die cast ones as well, some are near useless out of the box. Not only made in USA but 2 miles from my house!

Bruce, One additional thing to add to your literature pile. ?I read and applied what i learned in this write-up when I was making the motor pulley for my lathe. ?You might find it useful as well.

Good luck! John ?
So you're planning to create a pulley, eh? I'd really like to see a video of that!? Most of us have to settle for fabricating things.

Going cast iron is not going to save any money regardless of how you do it unless you pour it yourself! They don't carry round 7075 but you might get a good price on 6061 from Clinton Aluminum. McMaster Carr can surprise you sometimes. Alro sucks price wise! Have fun,

Thanks all! ? Glenn N – Yes, Robert Downs put this file in the files section. ? Brad – How can 3-D printing & casting & machining be less expensive than the piece of aluminum? ?

Kay Davis / Dave Matticks – 7075 seems much more expensive than the other aluminum choices. ? Craig Treleaven – Thanks for filling me in on the edits I make causing problems.? I get the update only daily, so do not have this problem.? The only times I do this instead of a separate post, is when I have grammar or formatting errors.? It seems like every group has different formatting defaults.? And in this group you cannot see what the final formatting is going to look like until AFTER you post.? Will try to be more careful. ? So everyone understands, it may be a while before I create this aluminum pulley.? I will update everyone when I complete this or have questions.? Prior to November, I did not even own a lathe, so I am new to this & still learning.? What might be easy to some, is new to me.? I am going to a) wait a little while to see if I can locate an OEM 60-29 pulley.? b) If not, then I will do the aluminum pulley machining.? As was discussed early in this thread, I do not use the drill press constantly & it is working as is.? So this is not an immediate necessity. --

Re: Craftsman 101.07301 with a 383.22970 chuck
I was scratching my head thinking i was missing something. Looks like to need to make a few tools to make this work.?
appreciate the help

That key is not for that chuck. The chuck you have takes a spanner wrench that goes in the holes on the chuck, spinning the outer ring. Another square wrench goes on the flats on the back of the chuck to keep the chuck from turning when you tighten the chuck with the spanner.?

Re: Craftsman 101.07301 with a 383.22970 chuck
It looks like the chuck on my little Unimat.? I believe you just use a piece of rod (called a tommy bar) to turn the scroll to tighten it.? You may need to use a cresent wrench on a jaw for leverage.
