Ball bearing sizes

Postby 13rebel » Fri Jul 02, 2010 7:53 pm

Can anyone make a definitive list of ball bearing sizes for different makes of allwins? It may come in handy.

This seemed like a good idea, but has yet started (mind you it could end up a very long list, unless things like Bryans are all similar and Wonders etc).... I noticed under the Parts section PM is selling various sizes, I guess it is a case of matching the machines to the numbers or of course trial and error... Anyone know what a Giant Wonders uses?

So to start and trawling this site the sizes and answers are (info trawled from the site)
A = 3/4"

B = 14mm
R&W "Whats my line"

C = 9/16"
S&L Fireworks

D = 1/2"
Payramid

E = 12mm

F = 29/64

G = 15/32"

H = 13/32"

I = 5/32"

An interesting topic, which in my experience doesn't appear to be an exact science. 1/2" balls for Bryans and BMCo allwins seem to be a fairly safe bet - it's generally considered that 9/16" is the correct size for most other makes. However, I have found a good number of exceptions over the years. For instance, I once had a Hat Trick which came with half a dozen balls (all different sizes) when I acquired it. I discarded them all and popped in a new 9/16" ball............could I get it to work? Not a chance. In the end, I had to use a 13mm ball. I also have a Parkers allwin (an original with Saxony type ball release), again, it won't work with a 9/16" ball.
I wonder whether the 14mm stated above for R&W column-fill allwins is correct, as it does seem unlikely that a British machine of 50+ years would have been designed to use metric sized balls. Can anyone confirm? The ball size is of course quite critical in these machines, because if the balls are too small, the final ball in a column won't drop back and trigger the payout.

I have a "What's My Line" and changed the ball bearings 14mm when I bought her. She came with a mish mash of different sized balls some got stuck in the channels.
Unfortunately I have the problem whereby the balls don't allign correctly all the time and I sometimes have to resort to giving the glass a tap to trigger the payout.
Especially when there a six balls lined up. I'd be very interested in knowing the correct size.

Dave, I suspect the correct size is 9/16". As I stated above, this is generally the correct size for most allwins............er, except it doesn't always work. !PUZZLED!

Thanks a lot. I wonder what the actual old size was? But modern day size is good for me!
