Ok guys, here's where I need the help. Sorry for flooding the thread lol.
Momentary Elongation of wire, leading to adhesion of wire surfaces in a contact microcoil-
Theory: The wire should stretch a minute amount and return to its original length and diameter as the tension is removed without losing the shape of the coils, causing deformation, permanently changing the resistance or losing contact between the wraps of the coil.
Concept of Test:
* If static weight is applied in the right amount, the stretch property of the wire should allow for it to retain it's original diameter & return to a pre-tensioned diameter and length, therefore holding the exact form of the coil with the maximum amount of stability in both shape and resistance. If the wire stretches any permanently measurable amount, the amount of weight is too high and must be reduced as the diameter of the wire will be changed, thus changing the natural resistance of the wire and causing the build to be thrown off.
* Whatever the permanent stretch weight is, the momentary stretch weight must be considerably lower to allow the wire to recoil and bind onto itself. Otherwise, the whole concept only serves to keep wraps of the coil as close as possible. ******************************************* Momentary Elongation Test results:
28ga A1: No stretch length: 4 in Tensioned length: 4 1/16 in Weight: 4kg
* Full return is possible at 4kg to nearly N/S length.
26ga A1: N/S length: 4 7/8 in T/L: 4 15/16 in Weight: 7kg
* Minor return to N/S length after applied weight, approx 80% return showing that adhesion concept is possible.
24ga A1: N/S Length: 5 in T/L: 5 1/16 in Weight: 9kg
* 24ga shows much more resistance to stretch, but possibly more adhesive properties because of that and due to its increased diameter. ********************************************* Elongation proof testing:
Build specs: 24ga A1 d/c build, 7/6 wrap, 0.35 ohm net target, 3mm ID
Test build 1: 7lb static weight (50% measured stretch weight)
*0.35ohm net res. Slight off-center firing to even & slightly cool just before legs and moderate orange color at 30w with full pulse of ~10 sec.
* Vapor production substantial, warm, moist & dense. Increased from non-tmc of same res and gauge at same power.
Test build 2: 10lb static weight (70% measured stretch)
* 0.38 ohm net res, moderate firing across full surface of coil surface with minor dark spotting in center of one coil during dry firing, heat ending almost instantly at legs.
Test build 3: 14lb static weight (100% measured stretch)
* 0.35 ohm net res, easy firing solid across the full surface of the coil with no discoloration. ********************************************** Expanded Build Profiling:
Test Build 1- 0.35 ohm net d/c without leg bend 3mm ID, vaping range 70-85w (7lb tension):
* Build tested on Doge v1, somewhat airy by airflow, coils mounted centered and outboard to maximize airflow with =/- 5mm legs. Bend in neg leg to allow centering with air holes; wicked with rayon.
* Coils made on modified coil gizmo with 1/8in rod, under 7lb of static tension via hanging weight. Coils are steady on building and mounting, but require a leg bend to ensure no separation during centering of coils.
Build Performance Notes:
*24ga must be held solid as it's centered but, has a very fast response time even at 30-50w when tensioned. Average vaping power of 70-85w gives near instant ramp up and almost no pvs. Coloring of wire (rainbowing) is difficult to achieve but oxidation appears consistent and solid across the entire surface.
* Density easily outperforms a 0.09 ohm hand-wrapped build on a tube mech with the same RDA. Tested with 80% vg unflavored diy and no flavor shown from wick or wire contamination. Heavy juice usage is nearly instant, crackle similar to frying bacon with no large popping even with a 4+ second draw. ****************************************
Test Build 2- 0.38 ohm d/c net res, with leg bend, 3mm ID, vaping range 75-85w (10lb tension):
* Build tested on Mutation x v1 clone with pre-bend on neg legs, d/c build shows +/- 0.38 ohm net res after dry firing & oxidation, wicked with rayon on an ID of 1/8in and wrapped under 10lbs of static hanging weight. Coils were mounted outboard & centered to maximize airflow, pre-bend in neg legs controls separation of coil wraps when mounting, +/- 5mm legs on each coil.
* Coils show even firing across full surface area with one showing a small dark spot during dry firing, no abnormal effects noted while vaping.
Build Performance Notes:
* Build fires near instantly (sub 1 sec) at 80w and shows little to no pvs after firing. Vapor production is smooth and dense, mildly warm and sweet. Juice usage is heavy as with the last build but seems to be solid with no cooking or caramelization and the wick shows no signs of scorching even on long draws.
Build 3 not noted as the results are nearly identical as Builds 1 & 2.
