Use a good 2 part epoxy. The one I use most comes in a quick set or normal setting formulation. These are in dual syringes. (resin/hardner) are in separate cartridges, but dispense equal parts with a single plunger.
1. Dispense equal parts Resin and Hardner on a piece of cardbord or paper plate
2. Mix well with a tool of your choice (tongue depressors work great)
3. Load 1-2 cc's (ml) of mixture into a syringe (no needle required)
4. Apply as needed around the coil/spider assy
5. SEAT COIL/SPIDER IN PROPER LOCATION, ALL AROUND THE COIL
6. A small acid flux brush is great for spreading the expoy evenly (cut the brissels short, 3/8")
7. Use a hair dryer on mid-heat, low air speed to quick cure the epoxy
8. AT ALL TIMES, MAKE SURE THE COIL AND SPIDER ARE IN PROPER ALIGNMENT LOCATIONS
That should do it. You can do a 2nd light coat if you desire. Two thin coats are better than 1 thick coat.
Good luck,
