DIY Bowling Ball Spinner

[Pacoelo]

(Essential Home Stainless Steel Mixing Bowl ) this was the bowl than you bought on Kmart

[shawbros]

Imagine if your hand slipped, and went into that belt.

wats a ball spinner do

[mlim23]

7.5/10 of the sketchy scale lol

[deanchamp]

@mlim23 i'd go for 9/10...

[rafebeck]

I took a 1/2" bolt and cut off the hex head. The shoulder of the bolt (where the threads aren't cut all the way) fit just inside my Delta drill press' upper shaft. I used an epoxy to adhere the bolt into the shaft (with a wad of paper at the bottom, so the epoxy won't run down inside the shaft.)and let it set-up for an hour or so. The wife's mixing bowl isn't quite thick enough for the weight, and it'll start flexing, so I'm looking for a polycarbonate dog bowl. Thicker side walls...

[rafebeck]

I made this last weekend. I was trying to save some money and it looked like a fun project. I followed the directions.

Everything was working perfectly until I pressed just a little too hard. The super glue couldn't hold my 15lb ball and my wifes mixing bowl any more. I could not have imagined how violent the following scenario could have been, but I had front row seating at this bowling-ball-gone-wild scene.

Sad thing is; I can't find my cat now...

[deanchamp]

@rafebeck the hazards of diy! i hope your cat has come back and isn't too traumatized

[prettypimpq]

@rafebeck lmao about the cat!!!!

[leontt9]

nice job buddy! Make one for me and I pay u 150 bucks for it.. hehe... In Australia it fukin cost around 600-700 bucks to get real ball spinner. By the way CHEERS! I'm from Melbourne too..

[mattchan6668]

nice job ..but I brought a drill press $80000 won in korea(around 70us dollors) and I am not using super glue with a headed bolt .I just drill six small holes around center then using a JB weld to weld the bowl .Make sure weld it in the centre .I was sanded 15 pounds bowling ball and no problems even the cg is not on top

[anakid123]

Cheap? Yeah. Providing you have all that equipment as in a drill press. What do those cost? heh, nevermind. I believe without a proper center of gravity that ball would topple over to easily.

[vizsladoggie]

would it run too fast if you simply use the other pully that is upside down for the ball cup instead of using the bowl. Just a thought. I made one with a car rotor with the brake surface ring cut off. Then i welded an old hole saw to it and put it in the chuck. Then i turned the drill upside down. It worked pretty good but i get some wobble. I like this one here better.

[Nofaces]

its not going to good over here. gotta get some some rounder bolts and the super glue doesnt hold too well. you have any more advice? what size bolt perhaps

[Nofaces]

i added a tight fitting washer, now just gotta let the plastic metal harden. super glue just wasnt cutting it. mayber ill get a video up later today..but we'll have to wait and see

[chickenpoper]

why do say at the end that this was made for under 80 bux. when it was probably made for under 15 bux

[deanchamp]

that is how much it cost to make in Australia, buying everything

[johnsland8]

@chickenpoper because the drill press was $70.00

[banjoec]

I guess if you were desperate for a good science project for school, this might be worth it. Otherwise I'd just spend the $200 for new spinner designed for the job.

[deanchamp]

unfortunately we can't easily get them in Australia for home use.

[winintheflop06]

wow, what a bunch of morons! thanks for the info, I'll have to try this.

[masonmiggilymoomoo]

what does spinning the bowling ball do??

[MrBowler17888]

Lol cg facing up then what about the other side???

[burns1210]

Or you can take it to the pro shop and they'll do it right for $5.

[crashbandit900]

thats all a ball spinner is any way plus if u worked a pro shop like i use to then u kno how to do it the right way

[deanchamp]

it can make the ball a bit unstable, depending on how strong the mass bias is (if it is an asymmetrical core). it isn't totally necessary, and you can sand/ polish it in 1/4 turns, but it spins much smoother on the psa.

[deanchamp]

um, you turn it over!

[123mugsplinters]

cg facing up huh? how can you sand/ polish the other side of the ball???

[justinmill14]

Where did you find your bowl? I got mine at walmart, but the bottom has just a sligh curve to it and is bending and flexing to much at the bottom.

[deanchamp]

i got mine in Kmart (Melbourne). they had different sizes, but the bottoms are flat.  not sure of the brand, but they were cheap.

[justinmill14]

what did you do to get the center of your bowl?

[deanchamp]

i used a compass with a texta

[justinmill14]

what is the lowest rpm setting on yours?

[deanchamp]

it just says 500min (whatever that means), but it goes around at a few times a second with the ball.

[BrunsNickVideos]

what did u use for the rubber padding?

[deanchamp]

i think it is copper pipe insulation

[poohenya]

That's a drill press not bench drill. Well i guess it doesn't matter anyways.

[deanchamp]

sorry about the terminology, wasn't sure what to call it.

[stevescars03]

well i tried everything like the video even machend the bolt within .010 of an inch to fit the hole in the drill and the glue didint hold up so now im guna take it to work and tig weld it ( im a certified welder ) but great idea realy aside from the super glue i got my used drill press for 25 bucs bowl for 5 and bolts for free thanks alot better then 250 for a new ball spinner

[deanchamp]

nice one, and i'm sure the weld will be much stronger, but for me, the glue is still working fine 6 months on, using it at least once a week.

[bigtiii]

I don't see how the super glue stands up to the pressure. I think I'd prefer a nice tack weld.

[deanchamp]

would be the way to go, i just don't have the know how...

[bowlerwannabes]

i made my own with an old blender, a bowl, a whole lot of super glue...and thats it...and it works fine...and alot easier too...ill make a vid on saturday or sunday

[groovy4]

Have you made the video of your blender/spinner yet? Very curious!

[tnasty830]

yea i wanna see it too

[nacpizle]

was the drill still usable after?

[deanchamp]

yeah the drill itself is fine - it is easy to remove the bowl and have it operate as a normal drill if required.

[bowlerwannabes]

whatd you use for the padding on the bowl?

[deanchamp]

just some padded stuff i found at Bunnings, but i was told after it is copper pipe insulation.

[erjifo]

Nice video showing how to construct a home-built ball spinner, but I have to wonder how safe it is to superglue a bolt to a drill that is spinning that much weight.

I'm also curious how much wobble the spinner has if the ball's CG isn't up. The recommended method for resurfacing balls is to do the top, the bottom, then turn the ball 90 degrees and repeat according to most authorities on bowling ball resurfacing.

[deanchamp]

the bolt fits tight into the manifold already, so the super glue holds it in place fine.

it can get a bit unstable depending on the weight block in the ball (mainly as it starts up and slows down) but for $80 it does the job.

i only sand the balls CG up and CG down, so the sanding rings are in the ball track a certain direction.
