Elliptic tip form profil...

[EL Picos]

Hi, I always thought that a normal radius shape was not the optimal, just for fun i drew different shapes from parts of ellipse, flatter in the center and more and more curved towards the edge, from left to right the drawings are more and more curved, what do you think about that?

 

[Terry Aeschliman]

Have you tested all of them for squirt? Or deflection? Or just maybe --You don't have that much spare time ????

I like a uniform radius tip because its contact point moves evenly across its surface as the tip moves away from center ball, making it easier to see and control exactly where it contacts the ball.

The shape is just as important as the material.

Some shots require material that can lasts multiple hits, other shots require material for just one or two.

What material did you have in mind for those shapes?

Logical enough. Me wise, I'd play with any of those profiles depicted. In fact the last gumball tip is the only profile that stands out at all.

I will test that in the future, I will do tool tip form on cnc with ceramic sand paper abrasive, not all the forms in the draw, they are to close from each other. Check the tip of Judd Trump and some others trim their tip like that, a more rounded form on the edge is less prone to miscue, I think.

I would bet that most tips are in fact not the same radius edge to edge from use and hand shaping.

What I would like to see how it would react to play is a tip with a bunch of bumps like one of those pebbled ping pong paddles but smaller. Or maybe a wavy tip like the image but at a tip width scale.

What I think is that at the center of the tip the compression elastic strength is at top level and more you go to the edge, more it decrease, a rounded form on the edge will keep a better compression strength than a normal uniform radius, more stable for high english and draw shot.

How about a variable hardness tip, harder in the middle, more pliable at the edges or vice versa. So a cored tip similar to some of the break tips where they have a middle leather surrounded by a harder material.

Anyone have the tools to do this? By a Soft and a Hard tip, punch out the middle and fill it in with the other tip. I would bet that the playability and feel of it would be pretty good. You'd need to use something like a soft animal-based glue that does not fully harden, or just pressure to keep the leather together. If some hard super glue was used, I think that would make the hit somewhat odd when the glue was exposed.

Those tips would not be easy to produce

But I don't think too hard either. All I know is that if Kamui or someone comes out with one like this, you are all witness to my idea on here first.

…a more rounded form on the edge is less prone to miscue, I think.

Any part of the tip that’s more rounded than a typical nickel or dime shape (max about 30 degree slope from flat) can only touch the ball on a miscue. A more rounded edge is less usable tip.

they're called 'Zan Hybrid Max' tips

The net nerds are going to argue with you as to why their tip shape is optimal. And give you a bunch of bullshit contact point info. But these a holes cant string a rack together

That look like this a bit

you have way too much spare time.

So skill and knowledge don't go together - and you consider yourself skillful...?

In my experience very few tips are constant curvature (spherical surface). The edges always have more curve and the center is more flat. I don't worry about it and I don't shape my tip other than during install and by whatever chalking and play does to it.

 

[Banger]

Like Bob said, the tip is going to flatten out some anyway. And reshaping it every few games will wear it out prematurely. This seems like a solution looking for a problem that doesn't exist.
