Made it to the shops today and found “my” solution to the diamond and steel dust getting into the ball joints.
I have replaced the original (exposed) ball joints with fully enclosed versions.
It is a cup and ball principle rather than a ball and race.
In the original the race is made of nylon and I figure it may wear if dust gets into it.We have all been searching for boots or similar to cover them without much luck.
So why not replace the joints with ones that are designed to be dust proof already?
Pic 1!Also in addition, the arrows “A” (below) show a rubber grommet I put on the arms.
I removed the original lock nut.
Figured I don’t need the nut as loctite will keep the arms tight in the thread.This will absorb some of the horrible bang you get when you bottom out the paddle.
As for the ball joints, I am very happy with the result and cheap enough.
They are called “heavy duty”, sealed and lubricated.
Very smooth, not at all tight like the originals.There is no allen key hole in the end of the stud for adjustment.
But I can use a spanner on the other side if I want.I’m not using the micro-adjust anyway.
Another pic shows how well the seal protects the joint.
Put it on wrong way around to get a clear view.
That’s It! 😉
Nice one BillyB.
Does the stud screw off the ball . Wondering if a swap with original is possible.Never mind on my wonderings. Just realized keeping ball from turning would be tough
It is a heavy duty version of the original.
Easy five minute swap, there is a place for a spanner at the front.
Only two faces though. (not a hex)
The guy in the bearing shop said the allen socket in the end of the original is specialty.
edit – I’m going to put a thumb screw on the end of that stud! 😉
Drill a larger hole part way into the “L” bracket from the outside, so a slightly larger female socket will fit over it, then …..Great write up and photos Chris. Thanks.
Did the grommets come with the ball end or where they separate?
No, just another reaction from an action, they are 1/4″ x 1/2″ cable grommets, from a hardware store.
Refreshing to hear an Aussie call a wrench a spanner. It’s been a while but have worked my entire career with English manufactures.
I forget to allow for these differences, as long as the meaning is the same I guess?
But be careful with the word “root” over here. :P:edit – Google root and Australia to see what I mean.
this heavy duty ball joint plus 50 pounds of lead weights should solve your problem of the base lifting up while stropping. :silly:
Ha, the ball joints are light in weight, very smooth also.
They are alloy, where the the original are steel with a nylon bearing race.
(HD alloy= 34grams and steel= 30grams.)
It might not be obvious in my pics, but my board is about 3″ thick and weighs 3.5kg.
Unfortunately the new crossbar hangs over the sides now, but I’m happy! :cheer:
