Is there a tool on the market that will let me slip a guide over it and give me the guide size ? Kinda like what a jewelery store might have. I'm having a hard time determining one size 6-7--4-5 etc and this would help my old eyes.Thanks

So many questions ,so little time

No, because there are no standard sizes. Most ceramic guides are sized per the inside of the frame opening, not the ring opening. Thus, depending upon the thickness of any respective company's ceramic ring, the actual opening of say, a size #10 can vary.

You can take a measurement of the outside diameter or the ring, which is going to be about the same as the inside opening of the frame, and that will tell you pretty much what you want to know.

Now and then I get sizes of guides mixed due to one doofus act on my part or another. Like dropping the plastic box with the compartments and spilling them out. To sort them, I stand each guide upright along the edge of a table with the opening of the ring facing me and then kneel or squat down to eyeball the guides one by one and place them in the right sequence or grouping. I do this quite often when snake guides are involved.

I take measured guides and drop them onto a rod blank. Where it stops, I mark it with the size. I use these marks to indiate guide sizes by dropping an unknown guide onto the blank and noting where it stops. Not scientific, but close enough. C2
