Very often nowadays, builds require upwards of 6g and more tip weight to achieve desired swing weights. This, let’s say 6g, now changes a 7 iron weight into more like an 8 iron weight. So my question is, do you recommend compensating for that when tip trimming? Perhaps tip trimming for an 8 iron, rather than the 7? If not, it would be akin to soft stepping.
If adding a tip weight is getting you into a normal swingweight range for the shaft flex you are using you would not do additional tip trimming and the shaft would play to it’s listed flex. If not adding the weight left you with a swingweight that is lighter than normal for the shaft flex you are using the shaft would play stiffer. If adding the weight took you to a swingweight that is heavier than a normal range for the shaft flex you are using than you would need to do additional tip trimming to maintain the flex of the shaft. On average we reference a D1 swingweight for R flexes and D2 for stiff flexes. These would be the normal that I refer to.
Graphite shaft manufactures will design and test their shafts with normal swingweight ranges.
Are you building to a certain swingweight for a customer or for your own preference? I have been building clubs for a long time and I have rarely seen any player that can discern between one swingweight to the next. Today’s lightweight shafts take very little time to get used to and I truly believe people are far too hung up on a set swingweight. Is there a particular swingweight number you feel that you must achieve?
Sorry I didnt answer your question but I really want to know why you would want to add that much weight to a tip?
