How are guides measured

[algdog]

all guides come with a number , say 10, 16,20
how does this relate to size, is it a mm diameter measurement or is it something different.

is there a chart available?

DANG GOOD QUESTION!!!

AND WHEN MEASURING THE DISTANCE BETWEEN GUIDES, WHERE DO YOU START THE MEASUREMENT FROM? THE FOOT OR THE GUIDE RING ITSELF?

[BYRD]

Each manufacturer can vary a little, but I believe ring size is the inside diameter of the ring in mm. So a size 8 guide will be 8mm ID.

As for Box's question, I think that is up to the builder. Personally, I measure from ring to ring starting from the tip. On the lighter speck rods I build I usually have three inches between the tip and the first guide. That three inches is from the tip to the ring on the first guide, and then measure the rest as well from ring to ring.

I may be off a little, but those are my understandings of how it is done.

guides are usually sized in MM... Often times, you can find a guide spacing chart for the guides and blanks - most are measured from the tip top back.

I find that to be a decent starting point, and then will usually do a static test to make sure the spacing is good.

Algdog,
Here is a good link for you.
http://www.mudhole.us/catalog/

In the first dozen pages or so, there is valuable rodbuilding info.
Your answer is on page 9 of the catalog.
Guides for spinning rods that have a ceramic insert are measured from the OUTSIDE of the ceramic ring to outside on the other side. So, 12mm guide will have an opening of about 8mm or so.

Hope that helps.

good info thank you
conventional guides 10 mm ID
spinning guides 10 mm OD

now I know what they are talking about

ceramics both measured OD of ring

As Paul said, they are both OD. I should not have had the word spinning in my answer. I was just typing.
