Hi all

I've seen hickory clubs that list the loft in "inches" rather than degrees ...

How do you convert, say, a Niblick with 1 7/8 inches of Loft into degrees ? Something to do with right angled triangles ?

Example below:



I saw a pic of a 1920s MacGregor catalogue page on eBay a while back that had the whole Go-Sum range listed with lofts liike this


Thanks!

I'd fathom a guess that they are using loft to reference the height of the face. Since you brought up MacGregors, It's been my experience that they listed club loft not from a vertical plane like modern clubs, but rather from the flat ground. so a 10* driver would be listed as 80*.

I thought it might be like hill gradient when you're driving e.g a 1:5 hill descent goes down 1m for every 5 m travelled forwards.

So this Niblick at 1 7/8" might be angled at 1 7/8" length for a standard 1" of height .. which if you work it out via trigonometry would give you a loft of about 55 degrees.

Would be interested to know definitively though ...

This is the MacGregor listing I referred to in my opening post:

I have a lot of the old MacGregor catalogs too - I always thought it was
referring to the distance between the bottom front of the club face and the
back topline in the hitting position.

Edit: I don't know this for a fact though.

Bella i always thought it was like this.  You put the club in a fixture holding the shaft at 90 degrees and measure the distance from a point at the center of the face towards the shot direction at the vertical from the leading edge.  Sound right??

Based upon the chart I would imagine that if you take the inverse sine (loft of blade/depth of blade) you would get the modern loft. In the case of a niblick that would lead to a loft of 54* but this is a guess.

The attached pic is what I meant, not the best picture but you can see the distance from
the leading edge to the back of the top line. It would correlate with the chart. The smaller
the loft on a club, the smaller the distance

Tad - are you saying the same thing in another way?



The club is a 1920s Stewart Niclick

i agree with Tad. I never knew there was any other method.
