Nock Height question

[9 Shocks]

When shooting 3 under and using a double nock set are you supposed to measure from the bottom nocks height on the string or the top nock. So say you set your nock at 5/8ths. Is the bottom mark 5/8s from level? Or the top?

Thanks. Kevin.

Usually measured to the bottom setting.

I take the top nock measure to the paper just to remember.

Bottom edge of the upper nock set(whether brass or tied). There should be a small gap between the arrow nock and the top edge of the lower nock set to prevent pinching due to the angle at full draw.

Hmmm ok

Thanks

Kevin, yup, normally the nock height is from level to the underside of the top (often the only) nocking set.  

Remember, when you do all of this, that from level mark (on the string level) to the top of your nock's actual height does not lift the arrow above level at all. The nock set has to be above that point just to clear level for the arrow.  

As pointed out earlier, leave a bit of a gap between the two nock sets so there is no pinch when the string is bent at anchor.

So you are saying that 5/8th setting on the square isn't actually 5/8ths high on the string

I agree with ChuckC that the measurement has to be a positive number greater than 1/2 the thickness of the arrow nock to raise the rear of the arrow above level.

5/8" - 1/2 the thickness (height) of the nock itself will be the height of the center of the arrow above level. Some nocks are pretty narrow and others a bit fatter, which will affect your nock setting a little.

5/8 inch on the square is 5/8 inch on the string.  Measure up 5/8 inch from the lower edge of the square and mark your string.  Then tie on or squeeze on a nock.  The bottom of that nock should be on the line you drew on the string.  Then go down a little more than your nock width and tie or squeeze on another nock.

If you nock 5/8-inch high, and your arrow is 5/16, you're only lifting the nock end of the arrow 5/16-inch above above square.
Hope that makes sense.
