I’ll have to side with Bill on this matter.? The only thing accomplished by telling someone who asked how to do something that they should already know the answer is to PO the asker.? Had he known the answer, he wouldn’t have asked.? Fortunately, someone else did give the or at least a answer.? Which was that at least with our equipment, it will probably require three cutters, a straight grooving tool and two boring tools, one LH and one RH.

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!

Yeah, 7075 is expensive but 6061 would work better than fine. 7075 just cuts so nice.

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.

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…………..

Bruce Varner

Thanks for the nice comments about the hand vise.? No production, at my rate of speed & at my hourly wage before retiring, I would have to charge about $2,800 per vise. Ha Ha!? I little too much, don’t you think?

Could not find a drawing.? Found one image online where a person had placed a rule beside there vise.? I just extrapolated from that.

Used the lathe, the milling attachment, the drill press, & the belt sander.? Could not use anything else because that is all I have………….

Jmartin957 – Thanks for the feedback about creating tools.? I figured it would boil down to experimentation.? I bought a couple of sets of different size tool blanks, just have not started playing with them yet…………

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.

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.

Bruce,

Yeah, 7075 is expensive but 6061 would work better than fine. 7075 just cuts so nice.

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,

Dave

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 – Thanks for the Speedy Metals link.

?

Robert Downs / Guenther Paul – Thanks for the suggestions on how to machine it more easily.

?

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.
