    DIY Billet Bridge for Carto Tanks

    Back Story

    I have been using the aspire BVC coil heads combined with the billet bridge in a billet box and am so impressed with the coil head that I wanted to make the coils work in all my carto tanks (which I love and have a large collection) I also wanted to be able to do it without huge modification using easily obtainable parts or from things the average carto tank user would have lying around.

    The first problem was how to connect the coil head to a 510 connection. This just about did my head in. I tried numerous ways of making and attaching a collar similar to the real billet bridge but the coil head would sit too low in the tank and the liquid intake holes where blocked by the bottom carto tank cap. So I grabbed various extensions, drilled them out and tried to attach. Nothing quite worked the pin was either too long or too short. Then I discovered the pin from an old atomizer was the perfect size for the aspire coil and could be easily exchanged without any modification. I then accidentally put the pin back in the extension upsidedown. Once these pins were switched the coil head screws into a regular 510/510 adapter/extension. The coil head plus adapter now sits at the right height in the carto tank and the Eliquid intake holes are clear and able to feed the coil head properly. The tiny orings on the coil head work to create a good seal between the coil head and extension so flooding is not an issue.

    Note: the pin now delivers air flow so it is important to use a pin and extension with a centre hole. The 510/510 extension also has air holes in the stem that can be opened or blocked if you need to (drilling or toothpick required)

    At this point the normal tube part of a billet bridge can be used to cap the coil.

    I wanted to make my own billet bridge at whatever length suited the tank I wanted to use. So I removed the insides of various carto and atomizer tubes. As I only wanted the tube I used the handle of a wooden spoon to push out. (Actually more force was needed so a meat mallet was used) apologies but kitchen implements were handy

    The white carto plug that are in the top of boge cartos is then used to funnel the air from the coil head up the empty carto tube and creates the seal between the coil head and the tube. I felt the airflow was a bit restricted so I made the centre hole a bit bigger. Voila it worked. A DIY billet bridge for carto tanks. This white plug being softish absorbs some of the sideways movement of the tube.

    Part Required

    New Aspire BVC coil head your choice of resistance
    Old or new atomizer needed for the pins (can also use DIY atomizer parts from HC)
    Empty carto or atomizer unpunched tube of your choice
    White carto plug
    510/510 extension short/long. Dependant on your choice of tank. I have used short.
    Extra tight top cap inner o-rings.

    Tools Required

    Leatherwork Hole punch (to enlarge centre hole in carto plug)
    Paperclip or pin
    Tweezers

    Preparation

    Using tweezers remove the pin from a new or used atomizer. (I used old 510-t)
    Prepare the carto/atomizer tubes by removing innards.
    Using a pin or paperclip. Carefully remove pin from aspire coil head. Do not twist as you may damage the coil tail.
    If necessary enlarge the centre hole in the white carto plug. (I used a leather hole punch)
    If necessary replace the orings in your selected tank.

    Making The Bridge

    Press fit the atomizer pin into the aspire coil head
    Screw the coil head to the extension (firm but not tight. Too tight and you can damage the tiny orings on the coil head)
    Press fit the carto plug to the end of your selected empty carto tube

    You have your DIY billet bridge

    General Usage Notes

    The connection between the tube and coil head is fragile so this is not a setup that can be thrown around.

    A sturdy tank must be used. Tanks that have sideways play in them through the tube (poly) will break the vacuum connection between tube and coil head.

    The billet bridge works in a billet box because it is held securely ontop of the coil head by the locking brass screw. You don't have this on a regular carto tan so you just rely on orings to keep the tube in place. Orings on the inside of the top cap must be sticky and tight else the tube will just pull out of the top of your tank, breaking the vacuum, flooding your coil and dumping your Eliquid.

    I have quite a lot of tanks with fill holes that lend themselves to this system but if you don't, your tank can be bottom filled buy carefully removing the coil head/ext piece and filling with a needle bottle. However, this does put additional wear and tear on the lower cap inner orings.

    For my prototype I have used a x6 tank. This tank has both fill hole and the added screw in the base to lock the coil head/ext in place, which gives me a bit of added stability and allows easy removal of the tank.

    Finally I have been vaping this setup for the past 4 days. Refilled the tank 5 times. The vapor is excellent and the taste is exactly the same as using the coil head with billet bridge inside the billet box.

    Improvements

    Huge thanks to another aussievaper GTadmin who made a delrin collar equivalent of the white carto plug for use in this setup. This collar give extra stability to the connection of the tube to the coil head/ext piece.

    Thanks for reading and feel free to comment or suggest improvements. This also links very nicely with GTadmins work on recoiling the aspire coils heads. (Link to be inserted)


    This is my draft and I will cleanup presentation as I go

    Great stuff Crisscross, how have you been finding the new bvc coils? I got some from HOV and put one in one of my old maxi novas and it gurgled away just like bdc's used to. I haven't tried anymore since, maybe it was a dud one.

    Looking forward to more of your mods, excellent write up too.

    I think they are excellent. These are the first clearo coils I have every really liked which is why I went to the trouble of trying to solve this.


    Not that i used them regularly because i hated the dual coils. I found the trick to the maxi nova's is to cover the top hole or driptip when you fill it from the bottom. Keep it covered while you are screwing the base on slowly. I always left the base on my battery. One less air intake valve.

    Also a quick blow through the drip tip while upside down clears it as well. Same as you would do in a kayfun.

    If you do have a go at it can you tell me if the instructions make sense and can be easily followed.

    The meat mallet was the closest I got.

    Cannot even begin to get my head around doing it for my elegance tanks.
