sndeshpande Posted July 16, 2008 Share Posted July 16, 2008 Hi All, I recently repaired a Snorkel (a Special) and thought it would be good idea to share my experience with everybody. The following is a brief account of the procedure which went rather well considering the fact that it was my first snorkel repair. Lacking a digital camera, I made a quick sketch of the Snorkel assembly and various parts of interest. Scanned version of this sketch has been attached to this post (and also stored on the web - here) for reference. [A]. Tools and Supplies used by me – 1. #14 Thin wall Rubber sac for Snorkel (Source: Wood Bin) 2. O-ring and Point Holder Gasket (Source: Martin Ferguson) 3. Silicone Grease (100% Pure, Food Grade) (Source: Silicone Grease for Divers) 4. Talc (100% Pure, Unscented ) (Source: Talc Powder for Billiards) 5. 1/8" x 6" Cabinet Tip Slotted Screwdriver (Source: Local Hardware Store) 6. Shellac (Source: Local Hardware Store) 7. Sac Spreader tweezers (Source: Local Hobby Store) (Note: Purchased but not required) 8. Dental Pick Set 9. Sewing Needle 10. Wooden toothpick 11. Wooden Skewer 12. Scissors 13. Ear Buds . Following are the important repair steps arranged in a decreasing order of difficulty – (i) Sac Replacement: The sac in the pen was still somewhat flexible and hence I had to puncture it by pulling it out of the hole at the end of the sac protector with a dental pick and cutting a hole in it. The sac protector on this pen was crimped. I un-crimped it using the sharp point of a dental pick. I did this with utmost care so as not to cause a tear in the thin sac protector sheet and also to avoid gouging the rubber stopper. I then pushed the rubber stopper out of the sac protector using the tip of an ear bud. While doing so I accidentally pushed out the inner rubber feed out of the snorkel tube. I noticed that the feed had twisted a little when it was pushed out so that the slit on the feed no longer aligned with the slit on the snorkel tube. I then decided to push out the feed completely, clean it, realign it and push it back. This was accomplished by slowly and carefully pushing it using a 20AWG wire. Luckily (beginner's luck!!) for me it slid out without breaking. This gave me a good opportunity to study this part carefully. Once the stopper was out, it was quite easy to clean the remains of the old sac and to shellac the new sac in place. I spread the shellac in a thin coat using a tooth pick and could easily slip on the new sac onto the rubber stopper without using the Sac spreader tweezers. I let the new sac dry for more than an hour. Before using the shellac, I had pre-tested the shellac for drying time. The sac received an ample dose of talc and the rubber stopper /sac assembly was pushed back into the sac protector. I carefully re-crimped the sac protector and ensured that it slid properly into the section. The snorkel assembly was allowed to dry overnight. (ii) O-Ring Replacement: This proceeded very fast. The rear cap was unscrewed. I noticed that the rubber washer inside the rear cap was intact. Then using the sharp end of the sewing needle, I prodded and carefully took out the old O-Ring. I inserted and anchored one end of the new O-Ring into the slot and then using a wooden skewer I maneuvered the remaining part of O-ring into the slot. (iii) Point Holder Gasket Replacement: This was easiest of all. Initially I found the new gasket very tight. However, after a few operations it loosened a little. I avoided using silicone grease as I did not feel comfortable with the thought of some of it finding its way into the feed, gumming it up. I hope the gasket will loosen up progressively with time and use. (iv) Final Assembly and Testing: I applied a thin layer of silicone grease on the spring and on the rear end of the touchdown tube just below the rear cap. Re-assembled the pen. Checked for the tell-tale sounds of puffs on the up and down strokes of the touchdown tube. Tested the pen with water. Squirts of water confirmed the air seals in the pen and proper operation. Disassembled the pen and tested for leaks from the rubber stopper onto the snorkel tube and inside the section. Satisfied with the results, I proceeded to re-assemble the pen and to fill it with Waterman's Florida Blue Ink. The pen started laying down a smooth, firm and wet line immediately on contact with paper. [C]. Conclusion: The snorkel is an absolute delight to work on. With patience and careful planning, the repair is possible even for a absolute beginner like me. Link to comment Share on other sites More sharing options...
