Re: Need Pulley for Craftsman Speed-Reducing Attachment
|
Bruce,
Not necessarily cheaper, but I want it cast iron. Plus, it will be way less work to turn down a cast blank than a solid chunk of bar. I probably failed to mention that it's a 4 step pulley, and ranges from about 5" on the largest diameter to about 1-1/2" on the smaller diameter. That's a lot of cast iron to whittle out of a solid bar. And Durabar isn't that cheap, either, from what I remember.?
Brad
Thanks all!

Glenn N ¨C Yes, Robert Downs put this file in the files section.
?
Brad ¨C How can 3-D printing & casting & machining be less expensive than the piece of aluminum?
?
Kay ¨C Thanks for the Speedy Metals link.
?
Robert Downs / Guenther Paul ¨C Thanks for the suggestions on how to machine it more easily.
?
Kay Davis / Dave Matticks ¨C 7075 seems much more expensive than the other aluminum choices.
?
Craig Treleaven ¨C 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.
