DIY golfball dimples?
(OP)
Hi guys, first time posting, hope this is the appropriate section.
So Im working on a project and plan on adding the golfball dimples.
Im trying to find a simple way to add these to a slightly compound curved surface. I figured approx 600, 4mm dimples.
thanks!

Remember, first define the problem, then solve it.
RE: DIY golfball dimples?
I will first make the basic shape of the part, and the take a mold of it But im not sure If I would add the dimples now or wait till I get the negative of it.
The base shape/mock up will probably be wood/bondo, possibly covered with fiber glass. (alternatively I might just use this automotive modeling clay)
But its not so much how to put a single dimple in, but how do I make 600 of them look uniform, both in spacing and in depth.
But I will probably use a larger then 4mm tool/ball, since Im not going for a full radius depth.
I'm working on it!

No guarantee this will work, I'm just spit balling.

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor

In theory, there is no difference between theory and practice; experience suggests that in practice, there is.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
RE: DIY golfball dimples?
It would work if you could fit a means of controlling the depth.
Based on the OP comments I am presuming he is doing this by hand on a plaster/fiberglass plug for a mold, which is why I suggested modifying a cutter to fit a microstop countersink.

RE: DIY golfball dimples?
I did have one thought that I could have the "centers" printed on a vinyl sheet, but still doing it by hand will make for some inperfection.

Hi AlpineAce,
You can probably get away with a simpler process than producing a large number of discrete dimples, especially if you know the predominant flow direction. You could introduce some raised ridges, roughly perpendicular to the airflow. The benefit of dimples is due to the fact that they trip the flow from laminar to turbulent, and this can be accomplished using a number of different kinds of surface features. Dimples are used on golf balls because the flow direction on a golf ball is arbitrary. On the body you are working on, I suspect that the flow direction is pretty well known, so even something as simple as some strips of tape might do the trick. Something like this also has the advantage that it can be easily modified, allowing you to experimentally determine the best placement and height of the ridges.
