biconicals with dimples work really well.
not sure of they work better than without dimples. But some years back - a friend gave me a couple of golf cross balls and one did the rounds of about 4 countries and an equal amount of members for people to try and make moulds out of.
Not sure which country it ended up in, but I never got it back
I have tried modelling golfballs in the past - but they tended to crash my cad setup.
As I now have amuch more poweful machine - I'll give it another go.
Plus I know a few more modelling tricks now
Once the basic golf ball base in made - you can stretch it into a biconical.
The actual maths to cover a biconical in dimples is probably beyond me
But I will give standard golfball type another go.
As far as weight goes - it's about the same size as the skulls - so around 60-70gms when dry. Withmy modelling clay anyway.
As my new 3d printer is now finished being modded
(sapphire pro 2 corexy), it'll be a decent test for that too.
