Swing weight scale idea - will it work?

[kregan]

Hi Guys,

What do you think of this setup to use a digital postal scale for swing weight.

Is there a chart available that would convert grams or oz. from this kind of setup

setup to swing weights?

That's a pretty interesting idea, actually. Might even be ingenious.

Yes it will work. Your goal is to match one club to the others. This setup will be perfect However I will suggest a simpler version.

Put a ridged hook/shelf/ledge where you scale/rocking arm is. The butt of the club goes under it just as your rocking arm has hooked the club butt.

Remove the rocking arm

Replace your fulcrum where the shaft mid is resting on with the postal scale and small object to act as club rest

Then all your clubs can be weighted to match each other.

You don't need any kind off chart nor any reference in SW at all. You are only matching your club to your club. If you are curious then some day just put one club on someone else's scale and you will know the SW number that everyone else understands. Like take one to a golf store.  All your clubs will be the same SW because you matched them using your device.

Way to simple Jon !  LOL

Actually The main reason for the rocking arm and fixed fulcrum point was to

eliminate mistakes in case the fulcrum moves on the scale.

With this setup I can quickly switch out clubs and not fiddle around.

I had the 1/4" shaft and bearing in my junk box. Rocking arm, base, fulcrum point

made from PVC trim boards.

So now how do I convert 14.4 oz to a swing weight?

I understand I don't need to know the swing weight but it would be nice.

Bravo brilliant ingenuity!!!

"So now how do I convert 14.4 oz to a swing weight?

The surest way is to measure your clubs as is on your scale And then take them to a SW scale somewhere. You can then try to figure out a pattern/relationship maybe. But at least you have a known equivalent.  You would need to add say 1/2 ounce to the club and get two measurements to try to identify a SW scale conversion to your 2 readings.

You could assume that the advertised SW for the factory club is correct and make that your 14.4 equivalent. (if your club is factory- or borrow a known factory unaltered club)  And then add weight per the various manuals that says  "One swingweight point equals 1.7 to 2.2 grams of weight, depending on the club's length. For example, adding 2 grams of weight to the grip end of a D-9 club would reduce the swingweight to D-8; adding 2 grams to the clubhead side would increase the swingweight to E-0." http://golftips.golfsmith.com/change-swing-weight-golf-club-20370.html the resulting notes becomes your scale conversion to SW

I doubt that there is any other method besides what I describe. The only other way would be to duplicate the supports and pivot points of a current scale. If that were the quest then you would be better off just buying one. Buy the wheel instead of inventing an identical wheel.  Your device is perfect now all you need to do is transfer your measurement to the SW scale reference.

Time to connect with someone who has a SW scale in your area to compare your findings  for accuracy

Out of all my clubs 3 are out of spec.

3 wood

5 wood

2-pw

52, 56, 60 degree wedges

52 degree wedge is 1 once light !

60 degree is 1 once heavy

6 iron is .4 once light

I fixed the 60 with a little tour grind!  :-)
