SwingW.com Swingweight Scale

[youngunz5840]

Digital scale came in. Super easy to setup. Tested it on a club that I had cool clubs measure a few weeks back and the scale came out .5 heavier. Nothing I would ever be able to tell so I’m happy with the product. 
just in time too as I’m waiting for a set of irons to come in that I am going to put LAGP l series shafts in and I want to match the swing weights when I build them. 
not super concerned that they all hit an exact number more that they match

I gave in and bought the Pro Touch Digital scale. I’m very impressed. I’m building a set of irons right now and I was able to get very consistent SW’s throughout the set thanks to this scale. It’s much easier/faster than the Golfworks economy scale that I’ve been using for years. Well worth the money, especially when comparing to other digital scales.

I have had the Pro Touch Digital scale for about 8 months now.  Used it for lots of tinkering and recommend it highly.

 

However, you need to be aware of machine tolerances/variances.  I have discovered that you can weigh the same club on different days and the SW reading may vary by +/- 0.2/0.3 SW points.  Also, total weight readings often vary by 0.5 grams depending upon when you weigh the club. 

 

I think I became a victim of the pursuit of perfection because the digital readings are calculated in 1/10 of a SW point and 1/10 of a gram for total weight.  I expected that the machine was able to differentiate between 1/10 of a SW point.  It really doesn’t.  A D1.0 reading today may be a D1.2 reading tomorrow.  Or maybe a D0.8 reading. 

 

Of course, in reality, the weight difference between D0.8 and D1.2 is so miniscule that it will make virtually no difference in club performance.  If you can live with these tolerances and get your mind to accept that D0.8 is essentially the same as D1.2 you’ll love this. 

 

But … you’re on the road to insanity it you are trying for the perfect 0.3-0.5 SW point progression between your irons.  You might get a “perfect” progression on the day you build only to find the numbers off in a few hours.  If “close enough” is not “good enough” for you, you will soon need a support group to put you on the road to mental recovery.  I am still “recovering” but have not yet reached “full recovery.”

 I've been using the Swingw XL scale for several months. The accuracy is within 1 swingweight of Golf Galaxy measurements on 2 clubs, I figure that should be representative of overall accuracy. 

 

With the XL, the scale is what provides true accuracy. I started out with a regular kitchen scale that only had one sensor, and the readings were not very repeatable. Once I bought a better scale with 4 sensors - one at each corner - the readings matched with Golf galaxy.

 

I'm getting ready to build a new set of irons - Takomo 301MB heads, Nippon 950GH stiff shafts and Golf Pride tour velvet grips - and I may put out the cash to score the top of the line model. Why? 'Cuz I'm lazy, and I won't have to take the extra 3 seconds to convert grams to swingweight...

[Southside Seminole]

After looking into these scales I’ve decided this is the 1 I’m going to buy.

 

I have a question for you guys: Can I dumb this down to taking the swing weight of a built club that I love the feel of & applying that in my new build as something to shoot for? I understand there’s some error worked into the different scales/ways of measuring. 
 

I’m wanting to try some graphite shafts in my wedges & figured I’d just use whatever SW my current gamers are. Is that the correct way of looking at it?

 

I’ve built like 75% of my own clubs over the last decade. Most come out great, but I can tell in some that something’s off. It has to be the swing weight I’d imagine. I’m really only talking about the crazier things I’ve tried like an MP-14 1 iron head into a hybrid shaft lol. I would never play that club anyways so no big deal. 
 

I’ve read through a couple of these threads & don’t remember seeing this question answered/discussed. Also, no need for any crazy technical replies like some that I’ve seen, I’m just trying to bounce an idea off someone.

I had one of the most finickiest SW scales at Golf Galaxy. Asked for a new one every month for years it seemed. When we got a new one, I took it home lol. Then passed it on to a friend but had to explain all of the little finicky things with it.

I use a postal scale, dry erase marker, ruler, and online calculator. With a socket extension in a vice as the fulcrum.

If that club is roughly the same length, has the same shaft weight model and weight, and the same grip - then yes.    The more those aspects of the club has changed between that club and the one your building, the less useful that value will be for any new club your building.

If the graphite shaft is lighter than the current shaft - then NO.  Definitely not.   If the graphite shaft is the same weight as the shaft in the current games - then it might not be too bad (assuming same grip is used in both).

It's possible but I wouldn't assume that.  Total weight can be important and various aspects of the build can effect the stiffness feel of the shaft even if the shaft might have worked in a different build.

 

Swing weight feel and fit is really about getting the combination of length, total weight (shaft weight) and head weight to sync together for the total "heft" feel of the club.    As long as you realize that the swing weight scale has a lot of limitations and what those limitations are - it can be an effective tool.   The swing weight values do not translate well in the context of certain changes so don't get overly focused on those values.    More often than not, the final head weight (and target sw value) for a new set or club needs to be figured out on on the range by feel and watching the results - not taken from a previous club.

Awesome info, thanks. I’ve read most of this before & I guess I didn’t factor in the “everything is different” enough. I now understand it’s not uniform & I’d need to build a test club up & do the lead tape at the range trick & go from there. 

[johnmharte]

I’ve had their version 1.1 scale since July 2022 and have loved it. I’ve tested against our local Edwin Watts scale with only a small .1 difference. I would recommend getting a 500g weight to calibrate/ check with. I’ve gotten a calibration 500g weight this summer just to be sure/help my OCD.  
 

Just used it a few mins ago building a “short” 44.75 driver.  🙂

Just got mine today (pro touch steel digital). 
 

My Cobras were in the E1-E2 range. The 85g shaft Edel’s were D8 range

gonna go through tomorrow and do the other sets too. Pretty badass.

Let us know how you like it! Considering this or the Mitchell Digital Auditor one.

I already went through a couple sets of clubs and it was shocking. My clubs I played last year were E2-E3. I knew they were heavy…but wow. 

 

I have two new sets of Edel SLS-01’s and one set is D8. The other set was E0 (I think). I will be going through them this weekend and writing everything down so I can start testing to figure out the right swing weight for me. 

 

Real lesson, I play the Jumbomax XL grips (ultra lite). They are 50g. In hind-site, I should have gone with the regular grips not the ultralite. That would have been the easiest way to make my swingweight much lighter. It will work perfectly for what I am about to do with the new SMS Pro irons (converting them to single length). I expect the 4-9 to be really simple. However, I wanted the scale to dial in wedges. Even though the heads might not be the same weight, I believe with counterweighting, I will be able to make all wedges play same swing weight.

Correct. Weird they didn't fit a 0 and LW in there. 

I think you can also just enter lofts for your clubs, correct? I just got mine and I think I saw that as an option. For my use, I will be using the scale and recording everything in my build sheet, so I won’t actually use the scale for tracking each club. But I suppose if I end up measuring other people’s clubs, I could do that.

[JS Golf]

Recently ordered the SwingW XL manual one which you use in conjunction with digital scale. I am Not sure if I am doing something wrong but it's TOTALLY OFF.  Recently got a Miura iron set and its supposed to be D2 swing weight but when I measured on the XL using digital scale, it ranges from 625 to 630 range.  According to the chart, that's D4 or D5. I know for a fact that it's swing weight is not that heavy.   Maybe I need  a new scale but the scale I am using is pretty accurate, I weighted Vega Iron Heads other day, driver weights and they are all pretty accurate.  Maybe off by 1 gram of here and there. 

 

Will get me a new scale and see if that changes things.

There is much discussion on this board about grip weight and its influence on swingweight.  Bottom line, most of the pros recommend using a 50 gram grip for swingweight purposes, and if using heavy/light grips, ignore the swingweight change.

I have that scale, you should measure the fulcrum distance from the butt end. I think it is supposed to be 14" and might be off. I imagine the 3d printed part is off or how they screwed it together. Mine reads half to one point heavier than the local golf shop scale so I take that into account. I have found that on the grip side there is a pretty close to a 1 to 1 relationship with adding/substracting weight. With split grips I tested a 50g grip and a 62g grip. The 62g grip read 12g lighter. I have a few clubs with 48g grips that I know swingweight heavier than they would with a 50g grip. The scale level is supposed to be flat. I have the scale sit slightly higher than level and that reduces the measurement to be more in line with the golf shop scale I've tested.

Did you make sure to zero out your scale first before putting the club in to measure the weight?

I guess it depends on your use case. If you are working on clubs for other people and you need specs to match something specific then that might matter. If you are just using the scale to make your clubs uniform, it shouldn’t matter at all. 

 

If you are hitting balls to figure out the best setup, then using the swing scale tells you what it is. No matter what it reads, E vs D vs C, you see that on your scale, that’s what works best. It doesn’t matter so much what anyone else has on their scale. If you are building clubs measured on a different device and it measures D2, but on yours it measures E2. Ok. Then you build to E2.

Yes I did zero it with scale end on.  Ordered a new scale so let's see if the new scale with 4 sensors work better.  Will post pics later.

I also have the SwingW XL and find it very accurate and repeatable, a good scale is needed. Found it useful to have a calibrated weight set to check things and verify, I have the one listed below and it comes in useful for other purposes, all the weights in the set were accurate.

Exactly how I use it. Mainly to compare what I am feeling between two different clubs. I test a lot of friend's clubs or demos before I buy and build. Having my scale consistent is the main goal. At the same time I like knowing someone else's scale says to have in the back of my mind. 

[JS Golf]

1st 3 pics, new scale with 4 sensors.  4th Pic, my old scale.  

 

What am I doing wrong here? 

[JS Golf]

Made a minor adjustments and made sure all the screws were in. 

It's showing 641 or 642.  Either case, still around D7 swing weight which I know it's not.  

 

Let me know if I am doing something wrong.

I don't have those calibration pack but

 

But I just weighted Vega irons heads to see how accurate the scale is.  #7 iron per Vega is 270g and #8 is 277g

 

Weight both at the same time and looks like combined weight is in line with what the heads are suppose to weight.

My grips are 50g. The Jumbomax XL ultralite. I actually do have some other grips that are the same size and 120g, but don’t have them installed. They are going to be part of my testing with the new clubs as a sort of counterweight.

What should the swing weight be? It's hard to tell from the photos but make sure the bubble in the level is centered, the red turn knob should be adjusted so the bubble is centered when the knob rest on the scale.

You can also do a manual swing weight measurement using the guide below to compare.
