johnw Posted November 15, 2019 Share Posted November 15, 2019 I have a set of .355 heads and I'm considering boring the hosels out to .370 so I can use some .370 pulls that I have. Pro's / Con's?

jaskanski Posted November 17, 2019 Share Posted November 17, 2019 Always use modification of heads as a last resort to club building. If there isn't a 0.355 taper variant to the shafts that you want use (and there probably is) then you have no other option.. Think carefully before proceeding any further. Long story short - fit components to fit components - never alter components to fit components unless you have no other option.

FiveGs Posted November 18, 2019 Share Posted November 18, 2019 Just make sure everyone you play golf with wears a helmet. On a serious note, I would strongly advise against modifying the hosel bore to accommodate a parallel shaft.

10shot Posted November 20, 2019 Share Posted November 20, 2019 If my memory is correct Golf Works has the "How to" on .355 to .370. Look at the bottom of their website, if not a quick call. Like bending irons, not all irons can be bent and not all irons can be drilled GW will tell you. 10shot johnw 1 Quote Link to comment Share on other sites More sharing options...
McGolf Posted November 22, 2019 Share Posted November 22, 2019 there is no problem to modifying the hosel to accept the .370 shaft. However, you must ensure the proper bore. If are going to use a drill bit then don't. A reamer or bottom bore bit in a drill press at low speed is the best cleanest way to perform the job. Weather its .355 or .370 the way it attached to the shaft is the same. Check fit and glue.

edteergolf Posted December 6, 2019 Share Posted December 6, 2019 It can be done without a problem if you possess the skill set. Other consideration is weight. You will reduce the weight of head some amount. That amount may or may not need to be added back depending on the desired final swing weight. Also, you would be using a cutting oil and oil is not a friend of epoxy. You will need to clean the hosel very well including the use of a degreaser before installing the shafts. I have done this several times in the past and have not had any trouble with clubs breaking. Besides a .355 hosel was at one point a .370. The notion that it has become weaker just doesn't hold any weight. Quote Link to comment Share on other sites More sharing options...
