PVC Mod (16340/RCR123, solderless) So many mods require drilling or a dremel. I think I am like most people and do not have all the required tools to prevent drilling through my hand with small parts nor do I have a dremel or lathe. After many attempts at a few different designs and a LOT of small parts, I have come up with this fairly easy do it yourself mod. This mod is finicky at keeping proper positive battery contact. Use safety precautions and assemble at your own risk. 4 Tools needed: pliers knife 1/2 inch pvc/pipe cutter (or hacksaw) ruler with United States customary units 9 Parts needed: (from Lowes) a. 1 push-on F Connector #302832 Not found on Lowes website.

(from Office Depot) i. Package of 1.5 inch brass fasteners (1 inch is too short) Office Depot Brass Fasteners 1 12 Length Pack Of 60 by Office Depot Extra Parts to make it functional: RCR132 Battery 510 atomizer & cartridge Instructions: 01. Cut 1/8 inch piece of the small tubing (5/16). 02. Push this piece over the threaded part of the F Connector. This smaller tubing around the threads prevents the ground wire from making continuous contact. This tubing does not need to be pushed as far as it can go. The bigger tubing may be used but may slip down if not wedged on. 03. Cut 1/8 inch piece of the big tubing (3/8). 04. Push this piece over the top of the F Connector below the top ring and ridge line. This will be a very tight fit. Leave ring on. 05. Insert one wire brad (nail) into bottom hole of F Connector and push it until it stops. Pointy end goes in first. Wire brad head will stick out. 06. Cut one inch length of 1/2 inch pvc pipe. 07. Push the pvc cap onto one end of this one inch length you just cut. 08. Pull apart legs of two 1.5 inch brass fasteners. 09. Grip the longer end of one fastener leg about 1/8 inch with pliers and bend over towards the top of the "button" into a U shape. 10. Do the same for the longer end of the second fastener. 11. Position both fasteners so the buttons are facing opposite directions. 12. Insert the two bent ends into each other and clamp tight with pliers so they end up hooked together. 13. With your fingers, bend the outside end of one leg over the top of the nearest button in accordian fashion so that no section is wider than the button. Do not let the leg stick out past the side of the button. Push the accordian together as much as possible. This will ensure good contact to the flat negative side of the battery. The button by itself did not always make good contact. 14. Leave about 1/2 inch of the opposite end leg (on the other fastener) by breaking the rest of it off by bending it back and forth with pliers. Bend the remaining attached 1/2 inch in half. This will be used as a switch to make contact with the edge of the F Connector. 15 Place flat negative side of battery onto accordian leg and push the other leg up flush against the battery. 16. Place the accordian leg side with battery into the pvc pipe with cap and push all the way down. 17. Slide open button through middle of pvc adapter, big side first. 18. Push pvc adapter tight onto pvc pipe.The button should stick out the top of the adapter completely. If it does not, you should be able to pull the button up a little at this point. 19. Slide F Connector into threaded end of pvc adapter hole all the way down, wire brad head first. It probably will not go down far enough to be flush but get it as close as you can. You want the wire brad to be touching the positive terminal of the battery. This will be the most probable spot of failure if the mod does not work. 20. Adjust the button and 1/4 inch leg piece so that the leg piece touches the F Connector edge when you push down on the button with your thumb. Important note: It should not touch when you are not pushing on it! 21. Attach atomizer/catridger to 510 connecter and slide into F connector. Note: The 510 connector is only used to make a good ground connection. Mod completed! F Connector is mostly sealed for battery protection. Ensure the button does not remain in constant contact with the F Connector. Remove the atomizer when not in use to prevent accidental activation. AFAIK it vapes okay, not enough experience or other PVs to compare it to yet. I think a 3.7 volt 16340 protected battery may vape better than the 3.0 volt R123 LiFePO4 I used.
