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)😊

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 smokers, while working ok (but noisy) have non replaceable elements, so if you kill one, it's off to file 13 at the end of the bench😉😁

The pump actually works quite well and if you mount it on sponge rubber it is reasonably quiet and could still be useful in a boat with a bit of interior room.

These photos show the stern modified ready to fit up the twin jet units that will power and steer this vessel.

More photos in a week or so.

At last after 8 months I've finished my Vietnam River Gun Boat.
I've built this vessel using a made up fibreglass hull that pretty much measured up to the 1/9th scale with some modification that I wanted.
I will post photos of the build of the build over the next few weeks and answer any questions as they arise.
These pics show the initial hull modification underway.

Inspired by jbkiwi's experiments on a smoker, and interested in developing one for my Crash Tender I have built an experimental rig based on using an e-cig for the smoke generator and an air pump. The air pump is driven by an electronic lash-up which pulses the pump at a rate depending on the throttle setting. The video shows two tests, first with the water off, then with it on.

Using the modified fan forced Heng Long smoker box, and a dead unit pump to pulse the smoke. This version is a 'dry stack one', which would look good on tugs and work boats. Still working on perfecting the 'wet' version.

"Shades of Autumn" - filmed on 20th October 2019 at the Pavilion Gardens Buxton.

In light to medium wind , even with just one servo on rudder only , the "Nip" is in its element tacking within a desired arc.
Adding the second servo for winch control provides adequate range for tighter tacks and broader reach/ runs.

Get the best mast position established - then just "SMILE" !.

Found a way of pulsing the water using the pump of a dead smoker (Hen Long smoker that is) In this test I used a pump to prime the smoker pump (smoker pump on 2s) and the rest is just syphoning through the pump to the smoker. You can vary the amount of 'spitting' from the exhaust by running the pump at low voltage or maybe using a peristaltic pump with a small flow.

I did not connect the fan powered smoker unit as I ran out of silicone tube, but the result should be the same as the last vid but with 'spitting' water. Using the smoker pump for water is not perfect as it would need sealing properly, and it's cumbersome, but you will get the idea. I have ordered a couple of small air pumps, so might have another crack when they come. I'll use them at the exhaust to disrupt the water flow if they are powerful enough, rather than use the smoker pump.

Ideal first build, convenient size, easy to transport, easy to rig, easy to sail. Will post more detail if required. Pure fun !
Enjoy !

Modified smoker (tank only) with 30x30mm fan assisted airflow.

Early days testing one of our member’s Canard on the lake... will probably go faster...😀

Hi Nerys, not sure if this is the correct place to post but here go`s ! - hope this helps.
Perhaps you can get some detail also from the videos. Hope you can see the photo files ?
