SiC Ring, Outer Diameter 7mm, 3 Pieces

Please carefully measure the ring size of your guide. If the size is incorrect, it will not fit. If you know the model number of your guide, you can determine the required size.
I offer rings in sizes 4mm, 5mm, 5.5mm, 6mm, 7mm, 8mm, 10mm, and 12mm. If you are looking for a different size, please check my other listings.

These are SiC rings.
Use them to repair broken guides.
They can be attached to guides where the diameter of the ring contact surface on the frame is 7mm.
Here's how to attach them:

1. Prepare the guide frame. The ring contact surface of the frame should be filed smooth beforehand.

2. As shown in the third photo, place the ring vertically and test if it can pass through to the other side. Ideally, it should pass through with a slight push. If it doesn't pass through, file the frame with a rod file to widen the contact surface.

3. Fit the ring onto the frame. If it's tight, gently crush it with protected pliers to fit. (See fourth photo)

4. Apply adhesive to the seam between the ring and the frame. Epoxy adhesive, which allows for some working time, is more suitable than instant adhesive.
Apply the adhesive to the tip of a needle or toothpick and coat both the inner and outer circumference of the ring.
A thin layer of adhesive is sufficient.

Be careful, as the rings can break if subjected to strong impact. They break cleanly with a crack, so be cautious when fitting them with pliers. A set of 3 is included in case of failure.
Another method is to file the frame more to fit loosely, although this will reduce adhesion strength.
If you use epoxy adhesive, it should not come off easily, so you don't need to aim for absolute perfection.

If done correctly, you can upgrade even inexpensive guides to SiC guides. If you are interested, please give it a try.
As this is a specialized item, please ask any questions you may have.
