Designing a Golf Club -- Part II

So, I've finished an initial design. 

I used the autoCAD program freeCAD to draw most of it, and the image editor program Inkscape to import the more demanding designs, like the geranium and the American flag. It took me about a week of learning the program to get comfortable with it. 

Not a complex design, but I am happy with the result. I haven't decided where I'm going to make an injection mold, a sand mold, a metal mold, or just CNC mill this first putter for testing. If I CNC it, this will be a fairly quick process, because then I don't have to buy smelting equipment and melt the steel myself (though the plan is it do that in the future. 

Even if it doesn't work the way I hope, it will have been a worthwhile project.

Once the putter head itself is made, I'm going to nickel plate it to protect it from rust (I'll be using carbon steel for the head itself), and then paint the words and designs in their appropriate colors. Once that is done, I'll install a putter shaft and grip and take it to the course. 

Lot more to do, but I'm on a good path.

You may need to do some back of the napkin CG location calculations. As soon as you remove material somewhere, it shifts the CG. So the club might not be perfectly symmetrical.

My guess is that the CG is closer to the heel than the center, considering the shaft. I don't know the math necessary to calculate the CG; something I'll have to learn! 

Thanks for the input!!!

Yeah, and the CG location is going to be important.

Also, do you want people staring at a flag when they're looking down at their putter at address?

Double check the CAD program for CG calcs. Some come with that ability.

you can do it by using a python console but it's not working right and I can't figure out why.

The flag can be changed; that's more for me than for wide use. I like having both a narrow aim line (the straight line) and a wider one. It helps me for some reason.

What's the end goal here? To begin to manufacture a putter for sale? Because… visit the PGA Merchandise Show some time, and you'll find lots of putters (as well as tees that get you an extra five yards). Everyone designs a putter, and yet… there's nothing special about any of them, really. Putters are just flat pieces of metal on the end of a stick.

I agree. Looks is really the only important aspect. Looks most likely translates to how a player says it feels nice. Just my opinion. 

Looks are how a player aligns the thing. Looks are quite important to a putter.

The end goal is to make a putter -- past that, I don't really have any expectations! I like making things, but in my professional life the work I do doesn't really have an end point, and having project that I can "finish" has been a lot of fun. 

I definitely agree RE: the specialness of any particular putter. I like the design I have and I think it'll look cool when it's done. But who know! I might hate it when it's actually out in the world. I've got a few friends and family who want one already, which is a cool feeling

      Favorite Las Vegas Course

      By Maroon88 ·

      I've played Bali Hai, Bear's Best and Painted Desert. I enjoyed Bali Hai the most--course was in great shape, friendly staff and got paired in a great group. Bear's Best greens were very fast, didn't hold the ball well (I normally have enough spin to stop the ball after 1-2 hops).  The sand was different on many holes. Some were even dark sand (recreation of holes from Hawaii). Unfortunately I was single and paired with a local "member" who only played the front 9.  We were stuck behind a slow 4-some who wouldn't let me through even when the local left. Painted Desert was decent, just a bit far from the Strip where we were staying.

      Day 106 - Worked on chipping/pitching. Focus was feeling the club fall to the ground as my body rotated through.

      Honestly, unless there's something about that rough there that makes it abnormally penal or a lost ball likely, this might be the play. I don't know how the mystrategy cone works, but per LSW, you don't use every shot for your shot zones. In that scatter plot, you have no balls in the bunker, and 1 in the penalty area. The median outcome seems to be a 50 yard pitch. Even if you aren't great from 50 yards, you're better off there than in a fairway bunker or the penalty area on the right of the fairway. It could also be a strategy you keep in your back pocket if you need to make up ground. Maybe this is a higher average score with driver, but better chance at a birdie. Maybe you are hitting your driver well and feel comfortable with letting one rip.  I get not wanting to wait and not wanting to endanger people on the tee, but in a tournament, I think I value playing for score more than waiting. I don't value that over hurting people, but you can always yell fore 😆 Only thing I would say is I'm not sure whether that cone is the best representation of the strategy (see my comment above about LSW's shot zones). To me, it looks like a 4 iron where you're aiming closer to the bunker might be the play. You have a lot of shots out to the right and only a few to the left. Obviously, I don't know where you are aiming (and this is a limitation of MyStrategy), but it seems like most of your 4 iron shots are right. You have 2 in the bunker but aiming a bit closer to the bunker won't bring more of your shots into the bunker. It does bring a few away from the penalty area on the right.  This could also depend on how severe the penalties are for missing the green. Do you need to be closer to avoid issues around the green?  It's not a bad strategy to hit 6 iron off the tee, be in the fairway, and have 150ish in. I'm probably overthinking this.

      Day 283: Putted on my mat for a while watching an NLU video. Worked on keeping my head still primarily, and then making sure my bead is okay.
