    Re: NON SMOKING EXHAUST WITH AIR INJECTION
    I've tried the large water pump I had in the HSL (swapped for a smaller one as it was heavy and overkill) and it worked quite well as an air pump (see vid - latest
    smoker
    model Y hooked to exhausts test) Problem is with these diaphragm pumps, is that the stroke is very short and they have to run fast to get any decent pressure. As mentioned previously I have some 12v 3D ceramic printer elements coming so it will be interesting to see how they work. I've also ordered 2 of the vape pens you mentioned to try $5.76 for 2 so it won't break the bank (thanks for making me spend money Martin!๐Ÿ˜‚) lucky I don't smoke or drink (or vape), although I might as well with all the glycerin I've been breathing lately! I think those tanks are what Graham used with the addition of a bigger tank, and they worked well. It's off to the hammock for me, so, afternoon from me (3.42AM here) must have me beauty sleep๐Ÿ˜‚ JB

    Re: NON SMOKING EXHAUST WITH AIR INJECTION
    Thanks for the info Martin, looks interesting. Might have a look on Ali Express and see what's available. I did manage to get the 'model Y' working in the HSL with the twin pump set-up but the problem was the same as before, with the exhausts on the waterline. If the boat was dead still and level it worked fine, but the moment either exhaust went under water it stopped working and the smoke just came out the opposite side. I hadn't fitted it properly and had wires and bits everywhere and all the stuff necessary would not have fitted anyhow. You need an air pump, voltage reg,
    smoker
    and water pump, plus all the hoses, so it's a lot of bits to fit into a space that's 2"W x 4"L x 2"H. Basically, to make it work as it is, I'd need the twin pumps (to keep the tubes clear (as in this vid), plus the water pump, plus a
    smoker
    , plus a
    smoker
    air pump, plus all the plumbing ( see drawing) It might not be a problem if it didn't have twin sound units and all the other bits and pieces, plus the drop floor in the wheel house which takes up heaps of space (not to mention 2x 2s LiPos, 1 3s LiPo and a 3v dry cell pack for lights/small air pumps. I might just leave well enough alone for now and have a look at your suggestion for the ST, which although not having much room under the cockpit floor, might have space for a small unit like that. Had another idea along similar lines, using ready wound coils on a base, packed with cotton and slid into a small alloy tube with end caps. They would be small and very basic and you can buy coil selections with various ohm ratings. I found the new coils I bought (50-85w are way too grunty and suck 3,7A at 2.46V - 41w (good smoke), but the first one I tried in the alloy box (40-80w) was only1.6A at 2.46v - 18.9w (good smoke) so there is a lot of experimenting that could be done for the best coil type. We have now (1 DEC) have had 15% GST (grab and snatch tax) put on all online O/Seas purchases, - incl freight (this labour govt is giving money away flat out so they have to steal it off us somewhere else) so this is going to add a big cost to R/C modelers here. Prices round the country are going to go up on every NZ online store as well. All because of entitled shop owners whining because they can't rip as many people off as before, - seem to think it's their right not to have any competition, - supposed to be a free market economy!?? (funny the govt is not targeting their online purchases, - only private sales ) If these useless t..ts get back in next time I might consider becoming Australian!!๐Ÿ˜ ๐Ÿ˜ ๐Ÿ˜ ๐Ÿ˜  My favourite $2 shops will probably be $3 shops now!. All that means I'll be buying less online now (batteries will now be an arm and 2 legs now) so I'm glad I bought all my expensive bits (TXs etc) years ago! JB

    EXPERIMENTS, REDUCING SIZE & NEW BITS
    (This is an update to the original post.) This is the model Y
    smoker
    and is a lot smaller than The model X. I was just setting it up to take a vid when the voltage regulator spat the dummy ( think it blew a power reg) causing the full 12v from the batt to go straight through to the
    smoker
    control and causing bad smoke to leak from the 3.7V electrics. Up to that point it had been working perfectly, with the air pump (ex HSL large water/air pump) being varied to reduce or increase smoke. The battery V was set to 3.5V using one regulator (fizzer) and the pump on another battery and regulator for the test. I was also using the vape module regulator as a safety for the coil (which in the event did work) The main regulators I'm using are supposed to handle 5A (probably Chinese Amps - like their shoe sizes๐Ÿ˜) but I think I'll have to go up more in amps for the next one I buy. I've had no trouble with these on pumps etc but they obviously don't like more than 2-3A. I've removed the vape electrics and its now wired straight to the back plate and center pin, working well again using another regulator (might buy them by the gross). There are 2 exhausts and a filler pipe on top, and the air inlet in the end of this version, and the pics show the components in order. A small piece of 6mm f/glass heat tube sits in the end of the element and mates with the brass air tube so the air is directed into the element. Pic of it running is at 2.5V and th 12V pump running on about 4V. Feet are just more pipe material, heated, bent and glued on with pipe solvent. The cotton wool wick is packed around the element and blocks any stray air from the pump escaping past the element to the exhaust. All the main UPVC tube sections are a push fit and are not glued so as to make servicing easy. It doesn't seem to leak (yet) as the end caps are a good tight fit. A small foil tray might be needed inside the model to catch any spills etc. A cap will be made for the filler as some smoke escapes from it as it is. Pipes are std 31mm UPVC plumbing but you can use any size you desire and if necessary this can be stood up and the air pipe run through the side (like the exhausts)rather than the end. Wherever the brass 5mm pipes are fitted, I've used some extra pipe material to double the thickness and thin cyano'd the pipes in, (making them a tight press fit when drilling). And she's now racing metallic blue as well. Hope to do the vid tomorrow, Happy smaping. JB

    , E-CIG ELEMENT
    This is the Model X
    smoker
    just created at R&D. It uses the previously mentioned (below) vape tank now fitted inside a highly technical chamber (waste pipe and stop ends). The previous drawing I did showing this method has now been revised, and airflow input position changed from bottom to top, as the bottom input forced the fluid through the wick for some reason and flooded the coil. Should have worked theoretically as it should have mimicked sucking on the mouthpiece but theory ain't fact so hence the change. Works really well now and if you blow on the tube gently, you can fill the room with smoke in real quick time, (lungs are now well lubricated๐Ÿ˜Š) Could have gone for a smaller tube but I wanted to have an air gap, as the vape tank gets hot on 2.5V after a while (too hot to hold). Might make a tinfoil shield/heatsink around it as well. JB

    Re: Gun, Decks and Capping Strips
    Yep that makes sense Steve, but I still wouldn't do it that way with that wire! It'll most likely kink while you're trying to fix the stanchions and the remainder are flopping about the shop!โ˜น๏ธ Had similar experience using tinned copper wire on my 1/72nd scale H class destroyer๐Ÿ˜ญ Eventually I sequentially fixed and pushed/pulled the wire through stanchion by stanchion rather than waiting until they were all fixed. Periodically I had to stretch the wire between two pairs of pliers to de-kink it, which was a pain in the nether-lands!๐Ÿค” Took a while on a 1.35 metre deck ๐Ÿค” But I cheated by making the main deck in two sections; midships so I could service batteries, distribution board, ESC,

    test 8 E-Cig version
    This version of a
    smoker
    box uses an E-Cig element in an alloy electronics enclosure.I gave the lid and box a 7mm haircut on the mill to reduce the size, (now 50x50x26, - was 50x50x33) but it could still be 1/2 the width. haven't found a smaller alloy box yet but might come across one, (only really needs to be 35mmx35mmx25mm The element is mounted on a bracket screwed to the bottom of the box (the box being the resevoir and neg) and against the outlet tube, and the pos wire runs through the side (in silicone tube) to the element. The box is packed with cotton wool which is surrounding the element and soaked in smoke fluid (in this case baby oil) but leaving a passage through the center for air flow. I'm waiting for a couple of air pumps to arrive but I've used the old
    smoker
    unit pump again to demo the smoke and pulsing, (makes good smoke rings too)๐Ÿ˜Š The element is capable of taking 4.5v, but I'm only using 2v for the test and it smokes quite well. The pump is running on 7v but can be varied from around 3v - 8v. The large tubes are to allow for later exhaust fitting (water or dry stack). Once I get the air pumps I'll be running this one with the water again. I've done this (like Grahams version to be able to easily replace the element as the Heng Long

    Re: SEAPLANE TENDER TANK TEST 2
    Re - that's what I expected would happen, and when that overflows I had already thought of a bilge pump for just those occasions Doug, (have enough pumps 'in stock') but it would be too silly, (I'd have to tow the dinghy with all the xtras!๐Ÿ˜) I'd even thought of a co2 cyl (soda siphon type) with a valve setup, (but again the dinghy). Just found some 30mm CF tube (ex helicopter tail boom) which might be good to fit a fan into to bolt to the side of the

    box. I'll have a look at the range of pumps on Ebay etc and see if there are any high output linear ones. Pic is off Youtube, guys done the same as me, just more compact with a 25mm fan glued to the side, - only about 1"x 1.5" (I made my fan box with a 30mm fan). Could probably make a custom
