Awesome video. Fun to watch and learn. I wish in my youth I had learned machining. It really is a thinking job... Lots of planning going into something that looks so simple. I guess that is why it looks simple... The project was well planned out in advance. :)
Curt Warkentin - Thanks for the comment and the feedback on the video. Glad you enjoyed it. Also, never to late to learn machining. I just started learning Fusion 360 less than 2 years ago and CNC Milling less than a year ago. Jump in anywhere and I am sure you will enjoy it. The learning journey really never ends.
Musicalbullet - Thanks for the tip on the scale. I will pull the cover and take a look. Still need to email Precision Matthew’s about it as well. Glad you like the vid. Appreciate the comment.
Musicalbullet - It was a small chip. I did a video of the quick repair and will get that out next Saturday. So easy to fix wish I had checked at the first glitch. I know for next time.

Bud, I may have missed something in the procedure but when you mentioned turning the part around and starting over It occurs to me that you might just “move left” one pulley step, part or turn off the smallest one, then re-do all the outside diameters. You would waste only the thickness of one step that way. With the price of aluminum stock that’s a significant difference vs making the whole part over not to mention all the additional work involved in removing all the stock again. Additionally you wouldn’t have to indicate the bore or anything, just keep turning and boring another fraction of an inch. Just my $0.02. Best wishes. P.S. Many thanks for the assist with my Grizzly lathe three phase control wiring a few months ago.
Chuck Saunders - I don’t think you missed anything. I think I missed a good opportunity to do something smart and easy 🤦♂️. Sometimes in the middle of a mess up the obvious escapes us. I am sure I could have extended the bore clean enough to make it work. I was counterboring the backside so really would have removed all of the fresh bore anyway. Good call on a way to save material. Thanks for the comment. Also glad to hear the Info for your Grizzly lathe helped.
@@BladesIIB Agree with your assessment regarding behavior in the heat of error correction. No telling what I would have done if I were making a video. I appreciate your taking the time to record the whole process. I will be making some multiple grooved sheaves for a tool post grinder in the near future and this was helpful.
@@Dogfather66227 Sounds like a good project, glad this was helpful. If your grooves are larger for a more traditional V belt you can also use the compound to finish cut them vs plunge. Better finish and better accuracy on the angle.
Maybe next time just grind your angles onto a parting blade and come in from the side? Save yourself a lot of grinding ! Not sure if you’ve seen it but nyccnc has a video speeds and feeds aluminum. Worth a watch
Zane Christenson - Good though, I a sure I have a HSS parting blade somewhere, that would have worked well. Will also check out the NYCNC vid. I currently use an app from cncdirt for my speeds. What was your thought, I was turning to fast or to slow on this part?
@@BladesIIB well aluminum is a pain in the ass no matter what lol but if you noticed when you parted it off it was making some beautiful chips. I would say test out what your lathe is capable of depth of cut wise with a decent feed rate. I think you’ve got either 1.5 or 2 horse on that motor? The bigger the cut and the faster the feed on aluminum the better unfortunately lol. When you get down to your finish passes of course you just have to deal with a bit of bird nesting but hopefully you can cut down on it throughout the process! Great videos though man and you’ve got an awesome shop
@@zanechristenson3436 I gotcha. I actually have 5 horse so I can push the feed much harder. And for parting I get lazy doing just one and generally feed by hand rather than cranking it up. Especially when I know I can turn it around and face it off clean. Something I will work on. Appreciate the feedback on the videos and shop.
Have you taken the scale apart and see if it is either broken or dirty? I have DRO on my mill for 2 years and it never failed me. But nobody (or rather few) uses DRO on lathes because 99% of the time the scale is good enough. I had a bandsaw that has poly V grooves, and it's a pain to find the belt or replacement parts.
@@BladesIIB Do you think it's possible that some steel chips (I mean steel is magnetic) has interfered with the scale somehow? I have been using glass scales on my mill and it never has problems.

@Dwarfgrinder - Appreciate the comment. I did do a revolve to make the grooves, but I am not a Fusion expert by any means so I am sure there could be a better way to get my sketch on there instead of a cross section? Thanks.
@@BladesIIB on anything circular revolving extrusions is a great way to have the entire geometry in one sketch. No need to extrude the cylinders as you can just dimension the radius of the whole thing. Makes the design more robust. Less steps in the ribbon. Etc.
stecy802 - At the time I was charging $50 per hour plus material (usually have customer supply material) and charged 4 hours for the pulley. Took longer than 4 hours, but the research and learning the angles for the grooves, and the extra time to video is not included in that so 4 hours seemed pretty fair. Making one off parts and prototyping does not go quick. Thanks for the question.
@williamkcallahan5675 - Thanks for the question. This is about a 4 hour project so I would charge about $300. That would be $240 for labor, $50 for material and $10 for shipping. Would also need you to send me your current one. I recall having to give a little more clearance on the back? If you are interested send me a note through the contact me form on my website www.BladesIIB.com.
Great job, Bud.

Might want to check for a broken scale or something stuck in the scale to cause it to malfunction like that. The pulley came out nicely 👍🏻

Good video Bud. Nothing worse than a DRO you can't rely on.

@@taiwanluthiers Yes someone else recommended looking for a stuck chip. Need to get the cover off and take a look.

Imo should have just sketched belt profile and revolve. But theres obviously multiple ways of doing this.

@@Dwarfgrinder Thanks for the tip. I will have to do some reading and watching to see what you mean. Always learning.
Jeeze, a lot of work. What did you charge for this job?

What would you charge to make another pulley? i need one.. I did exactly what your friend did.
