It is many years since I took a golf ball apart, but I remember unwinding what seemed like miles of tightly wound rubber band type thread, and in the middle was a half inch diameter squishy ball full of something that looked like white lead paste. Not really the sort of thing that can be tapped very well. Perhaps newer golf balls are made differently. If I was doing this I think I would use billiard/pool balls.
MobyDuck, I was of the same mind.. Th last time I had anything to do with golf balls was when I was a youngling and you are correct miles and miles of rubber band never saw any white lead past stuff the little rubber balls I cut open had as clear liquid in them.
I doubt if there are any of those type golf balls still around. I'm fairly certain I di my part in cutting up most of them and winding the rubber band into 1 giant ball.
The yellow golf ball my friend gave me have some hard filling in them it drills well but if you run a 1/2" drill in it the hole is only going tt wind up around 7/16" I used a 1/2Bit and drilled about a 1/2" deep then used an undersized bit to drill another 5/8" or there about then tapped for 3/8 16 tpi You can cut threads in them but the hole reduces after the tap is removed. No biggie it just means they stay on better.
Funny thing the golf balls I have say practice on them I felt that was fitting since I was practicing making knobs for my drill press had they not been found to be suitable I was prepared to make some out of aluminum
Yeah there probably was no need to thread them but since my handles are 1/2" and the thread on the end is 3/8".
I did drill 1 to 7/16 " about an 1'"Deep then forced it on. to me it felt like it wouldn't stay on very well even though it was real tight to get on it felt wobbly when pulling down on the handle and it would turn in it. I step drilled the other 2 and threaded them they screwed on tight and I could feel them bottom out. If the 1 gives me problems later I will remove it and mix some epoxy to hold it on with.
I often drill 3/4 to 7/8" holes on that drill press without first drilling a pilot hole. the 1 1/2 hp motor #3 MT has plenty of power and since it is extremely bothersome to change the speeds I just leave it in the lowest RPM (250) setting My other drill press is slightly smaller 34" HP #2 MT I leave it set in the 550 RPM range but it will barely drill a 1/2" hole direct through 1/2" plate steel It is a craftsman and has a really crappy cast handle. To me they feel like they were cast backwards
