Title: Shimming runners Post by: dnus4925 on December 23, 2015, 10:20:07 PM I've got a new plank, and my reference set of runners (using a dial caliper) come out to .002 toe in, I have another set of runners that come to less than .001 toe in. My question is, What is good for shimming? Does Kapton tape work? The thinnest I see with the adhesive is .0022. I know it comes in different thicknesses. I have used 3/4 oz glass wetted out, but that comes to about.005. But with some glue, that comes to about .007. What do other people use?

When I see top sailors using scopes or triangles with string on the ice Maybe just some epoxy and sand to your specifications Title: Re: Shimming runners Post by: Bob Gray on December 24, 2015, 08:39:41 AM I too wouldn't worry much about a couple of thousands but if you want shim stock you can make your own. Go to a hobby shop and buy some thin fiberglass sheets. While you're there get some Super Glue and a activator like Insta-Set. Place a piece of the fiberglass on a piece of wax paper, saturate it with super glue, squeeze it smooth and give it a shot of Insta-Set. You now have a sheet of shim stock that you can cut up and super glue it to your runners. If it's not thick enough, glue another piece over it. If it's too thick, sand it down. Believe it or not these shims last a long time, I've got some plates that have been shimmed like this for years.

That small a misalignment is within measuring tolerance. One light pass on one side with a sharpening machine will change the edge more than that. |
