Makin Sumthin From Nuthin no worries man. I still enjoyed it. I always enjoy your Vids. I have been building things from junk lately. My welds are getting some better. I built a welder cart. I also made a cover for my welder. Next project is a trailer to haul lawn equipment on.
Very nice finish Richard , that will be something the grandson will have for many years. Definitely not one of the cheep toys that are built in today's world.
Try putting a T land on the cutting edge of your parting tool, you won't believe how much better it will cut. Use a 10 t0 15 degree angle on the top of the blade and only take off a few thousandths 5 to 10. It will be like the T land on ceramic cutters. If done right you will love the results. Steve
Parting will always cause me lack of sleep. LOL My machine may be rigid enough being a 12 x 36 but it is in a wood shop 10" off the ground on cinder blocks so I lost the rigidity battle right from the get go....but do my best :)
I love it! One hell of a job for real! Ive used ball-bearings on a few of my tops.. One thing you can try on future projects, smaller ball-bearings. They keep the top from walking all over the place. Anyways, Excellent job brotha, High Five!
That's a beautiful top! Maybe machine out a parabolic dish a few inches in diameter for it to spin on...something you could engrave a message around the bottom of for your grandson. Just a thought
Lovely....from the beginning of video I was thinking using a smaller bearing ball, but pushed into a deeper hole and a little beyond center of ball, then with a tool pushing the end over so ball can't fall out. I'm afraid after some dropping this ball can come out. Now a little engraving would be nice also. And...if it was building one myself...about 3 flats/grooves or spheres milled across on top and painted/filled red paint or something so one can more easily see motion.
Those are all great ideas, given more time I woulda spruced it up some! If the ball comes out I am sure Grandpa will be called upon to fix it, but I used a liberal amount of loctite on it. Thanks for watching and the great comment! :)
I wonder if you fully assembled/ roughed it all out, then finish turned it between centers, if it would get rid of that tiny flutter it has. That said I gotta believe that bison chuck repeats beautifully to get the fine result you did. Nice job!
I actually wanted to do that and went so far as to taking out a lathe dog but felt it would damage the knurl so 86’d that idea. (order of operations bit me) The bison chuck is a really great chuck, love it! 😊
I wonder what the effects would be if you were to drill four to six 1/2" holes around the inside of it. Would be lighter but would also be easier to spin. Maybe get a bit more speed and 'hang time'. Looks great to me. Fantastic job!!! Gotta love machining!
Thanks John, it was a fun little project. Just wish I wasnt sick as a dog at the time, I was hoping for a better presentation than what I delivered for y'all to watch
That is pretty awesome Richard. It occurs to me that a very course thread pitch cut on the OD with a scratch pass or a hair deeper would give a barber pole effect on the outside. Nice Job!
Yea, I don't know what the ration difference is, but trust me, that cross feed is moving faster than carriage feed. I have my feed rates gear reduced to 50% and I power cut off but it's dicey!
good save on the project. I wonder if a really small ball bearing pressed into the end would work, I know you were pressed for time on this one. all the best bs
Another case of something I've seen people do that I would've done differently... mostly talking about the set screw thing, I would've just turned down the brass and cut threads on it, brass holds a thread easier than aluminum does. Tapping it out and putting in the steel screw was unneeded. But like I said, would've done it differently. Not saying you are wrong, just a difference in how we see to do things.I have the same issue watching people paint miniatures for tabletop gaming... or watching people build little engines and whatnot. I wonder how long it'd go if you put a bearing on top to hold onto and put a rip chord on it. ZING! hear the thing scream and watch it spin for an hour :P
I was just building as I went along, it was totally over-engineered but was a fun project to make. I am sure there are hundreds of ways to have made it better than what I came up with 😊
The "top heavy" issue is not completely a result of the top's center of mass height; rather, it is a result of a combination of several parameters, including the radius of the tip. A tip that is too sharp will not be able to "walk" across the table surface, and thus cannot restore the balance of forces needed to keep the top stable. Here is a link to a better explanation: www.physics.usyd.edu.au/~cross/SPINNING%20TOPS.htm

Thanks for Watching! ~ Richard
I like the ball bearing since this is for a child - super project, thanks for sharing!
Very pretty your grandchild will love it for years.
Thank you sir, I appreciate you watching. Have a great 2018
Granddad is so cool. That would be great mate.
Thanks Just Jo, I appreciate ya 😊
Finally got access to this. Finished off very well. Need do something for our Kid as well.
Thanks for showing and sharing

Thanks aR M, sometimes the little guys get forgotten, we need to try and remember them more 😊 Thanks for watching!
Great job I am sure your Grandson loves this.
I appreciate the kind words, thanks for watching! 😊
That really is a very well made top. That ball bearing is just engineering genius :)
Leave it to rich, to make up something so rich :D
Thanks Alucard! :D
Glad to see another video. Hope you are feeling better
I was very sick when this was filmed, It really affected the qualty of the video. Sorry Guys! 😖

Nice, nothing like making what you need!
Looks like it really works well. I often suffer from design build so revisions on the fly are no big deal.
Thanks Brian, it worked better than I planned. Cant wait to see your HBM go in
Very nice finish Richard , that will be something the grandson will have for many years. Definitely not one of the cheep toys that are built in today's world.
That was the goal, something that will last rather than plastic store bought junk 😊

Thank you for that, I am just a hack machinist at best. Will give that a try 😊
I think your doing fine, parting is one of the hardest things to get right on a lathe.

The intro show great balance in the spinner. Great work. A great Christmas present. Hope 2018 treats you and yours well.
Thank you Sir, have a great day!
very nice fingers..from God created Human to invent and produce the life.....from Iraq-kurdistan
I appreciate ya, thanks for watching Abu 😊
Looks good!
Thank You RTK :)

Sweet ending bud. Using the lense was/is brilliant fella ! I am sure your youngster will be really pleased !
Thanks Dean! 😊

I wanted to do a 6 hole bolt type hole pattern but ran outta time :( Thanks for watching Jared 😊
Nice looking top! I'm a little surprised you didn't make the flywheel laminated 3 piece design :-P
Thanks John, it was a fun little project. Just wish I wasnt sick as a dog at the time, I was hoping for a better presentation than what I delivered for y'all to watch

Given more time that may have been incorporated! :)

They was some thick chips! Parting makes me cringe
You must show us the little guy !!
Maybe one day!, thanks for watching 😊

all the best

That was the smallest ball bearing I had that wasn't damaged, thanks for watching

You should get ya a small lathe, very satisfying hobby Otis 😊
yeah I probably would if I had the money and somewhere to put it.

Thanks for sharing that. I was so busy trying to make it look nice that I didnt put in as much thought on functionality as I needed to at the time 😐
Been there, done that - especially during the 11th hour!
