A DIY Stroke Lab shaft? Why not!

Recommended Posts

Cool project! End result looks pretty cool too! Nice work. I’ll have to check in and see how you like the feel of this DIY.

This is neat. When rolling a stroke lab, the first takeaway was how much better I felt the head weight thorough the stroke. Does this have that same effect?

Love the ingenuity in this and interested in hearing the results. Wish I had thought of this!

Just to help clarify what stroke lab did was to make a putter that had the same total weight and distribute the weight to the head and grip ends. Pretty sure You can find the % distribution online.

Would have been nice to know the component weights before you put everything back together to see how it compared to the strokelab setup.

This is a really cool project I wouldn't have thought to try. I'm interested in your thoughts on performance and feel. I found the Stroke Lab concept very compelling - I could certainly feel the "stroke" more and would even say it helped me swing the club. My issue was more the feel of the insert. I have considered doing a Stability Shaft or a Stroke Lab shaft on my gamer but I don't want to mess with it so I haven't touched it. I will be very interested in your thoughts on this. Well done!

If you prefer a milled face the new Toulon putters are available in stroke lab as well. You could go give those a roll and see if you like them.

A couple early observations:

I played 27 holes yesterday, celebrating my 40th birthday. Played 18 in the morning with my sons, and then another 9 in the afternoon with another local pastor whose a close friend of mine. My short game remains a total flaming Hindenburg, but I had a really nice day putting: 44 total putts for the 27 holes, or 1.63 per hole. I really didn't make anything terribly long, but (this was key) I wasn't missing short ones. I think there were maybe two or three putts all day that I feel I should have made that I didn't.

Comparing strokes gained putting in yesterday's rounds with the five rounds before:

So the first positive here is that I didn't destroy my putting by disassembling a putter that was working well for me 🙂

As for feel: I can't say that the feel of impact has changed a lot, but the putter feels very balanced and very comfortable.

Okay, so I just did this same project 4 days ago. Strange coincidence.

I did it to my red ball because there is no stroke lab red ball. I find that mine has noticeable flex to it. Not so much on the actual putting stroke, some but not much. But if you give it a Jason Dufner waggle you can definitely feel it. I used a stiff driver shaft and then today replaced that with an X stiff hybrid shaft. 25" of hybrid shaft and 10" of metal. Thoughts?

Interesting. Do you find the flexibility the same between the two shafts that you built? How much overlap do you have between the steel and graphite?

This is very tempting for my EXO 7s from the year before they put stoke lab shafts into the EXO line... Great work on the build... I don't think I ever had a round of 1.6 putts/hole, jealous. 

Hope it keeps performing for you. Speed control is my biggest issue so the stroke lab shaft is of interest.

The x stiff was stiffer. I have since solved the problem by using a carbon hiking pole. Works great.

I thought I was going to have this finished today, but the grip I ordered has been delayed by USPS. The rest is done, however:

I'll do more of a play by play of the build when I have a keyboard handy. One addition: there's a small piece of shrinkwrap at the joint. It's covering a tiny bit of paint chipping on the graphite, giving it a cleaner look.

I am going to try that--- Just have to figure out which putter I want to try it on. I am thinking I have a Ray Cook mallet in the stash out there but can not remember if it has a straight or bent shaft in it. I may try it in one of the numerous Ansers I have since I have been putting on and off with them for 40 years. In fact I have some Matrix shafts in the shop and I also have a steelfiber one too. I will figure it out after Church tomorrow. Also remember I have a bunch of those old Pro Force 65 Gold ones too in X flex which are about like rebar

Also I will enlighten you younger guys about the twist and torque thing. A lot of your older putters ie: Bulls Eyes , Spalding TP Mills and Tad Moore came with what is called a 'fluted shaft"- Those shafts have like little intentions about 3 or 4 inches above the head. That is said to help with torque etc and enhance feel. I know a lot of us older guys will sometimes stick Bulls Eye flare tip shafts in Ping and Scotty putters for this reason. A flare tip shaft is one where the shaft actually slides over the machined part of the hosel.

LOL just thought about something funny. You said in your original post you were thinking of fixing the seam with pinstripe tape. For me I would use electrical tape or medical adhesive tape. On my end it would be for kicks and giggles since most around my home course think I have a screw loose or am a nut case. I can hear it now " That Stu has flipped out he has a putter with half a graphite shaft taped together with tape" Now one thing I can tell you is if you are concerned with graphics on the shaft you can conceal by using electrical shrink wrap. There is not enough heat involved to hurt the shaft's integrity or the epoxy bond. In fact you can melt the stuff with a hair dryer. Lots of DIY guys on WRX have custom colored shafts like that. I have not tried it myself personally because I am not into all of that but just offered a suggestion

Not sure if you saw, not I went with the shrinkwrap on my latest build, two posts above. I've used it for whole shafts before; this is the first time I've used it for an accent.

This is very interesting. I love that you guys are doing this. I have always wanted to tinker, but the cost of all the equipment has always stopped me. So kuddos to you guys for doing this.

 

Here are some  questions I have regarding this. 

1. Would it be best to use the stiffest possible graphite shaft possible for this set up? 

2. Other than changing the weight what are you trying to accomplish? 

3. Are you negating the potential benefits of the graphite by putting steel at the end? (only as strong as your weakest link idea).
