• 2x drills with stop collars - 1x 7/32", 1 x 1/2"
• 1x Catheter syringe
• Epoxy and thickener
• "Pam" spray oil

1. Drill the 7/32" hole 3 1/8" deep. (or about 1/8" longer than the bolt you are using.)
2. Drill the 1/2" hole (using the first hole as a pilot) 2 3/4" deep. (Note: I "rock" the bit slightly to create a wider bottom to the hole. The epoxy will hold better as it tapers to the top.)
3. Spray the bolt with Pam or other oil - so the epoxy doesn't stick - important.
4. Insert the bolt and screw so that it sets into that 3/8" extra small hole at the bottom of the bigger. (The bolt should stand up in the bigger hole. Do not over tighten.) Experiment with the bit size of that bottom hole. You want the threads of the machine screw to cut into it - but not be too sloppy.
5. Mix a small batch of epoxy thickened to Ketchup consistency in a small disposable cup. Using a catheter syringe (one with no sharp needle) suck up some epoxy, and inject it into the space around the bolt. (Don't get a large syringe as it is harder to inject into the hole - you can always "sharpen the edge" if need.)

Wait until epoxy cures - badda bing you are done.

I use a sharp file to take the excess off the caprail. Shouldn't have to worry about the epoxy showing as the holes will be covered by the new track.

• If you get voids etc - just re-drill and redo.
• We use a Milwaulkee M12 cordless screwdriver and set the clutch low so the machine screw won't strip out.
• If you are using Nutserts then skip the first hole. Drill the appropriate hole for the nutsert, screw in nutsert, spray the Pam on the screw, screw into the nutsert, inject epoxy.

Practice on a scrap piece of something. You will quickly get a feel for thickness and amount of your batches etc.

Hope this is useful.
