In case you have a smoke device using these or any smoker you can fill remotely by this method. Just used a reservoir and (for the purpose of the test) a 6v water pump running as slowly as possible. Pump sucks fluid through the smoke tank from the reservoir and recirculates it back to same. Reservoir fluid level needs to be level with, or below the smoke tank inlets to avoid siphoning to the tank and flooding the wick. With this system it only takes a few seconds to fill. You could also use the same idea manually with a deck filler and overflow. Either system must be sealed (airtight) to avoid fluid draining from tank when not in use, ( Manual system - both tubes plugged after filling) This idea does away with disassembling E-pen to fill .

Think I've finally sorted the mixing smoke and water for exhausts problem. Graham has already done his using the same pen / e-cig unit but with some nice electronic controls for the on off system, but not having the electronic abilities I've just gone with a more basic method. Wired up the pen and installed a filler tube (2 tubes are better - one for a breather) these are capped after filling to prevent air getting back from the pump. This system has a water pump, an air pump and the smoke unit, (all adjustable with their own voltage buck) Thanks to Martin for his pen suggestion. I was previously using large capacity elements fitted in various containers for my experiments (truckloads of smoke available) but these pens are great for tight spaces and don't draw much current.

Air, and a small amount of the cooling water are mixed by venturis just short of the exits (the air pushing the smoke and blowing the water clear of the smoke tubes). I've fitted the same system into my ST but am still waiting for the air pump from China (postal system problem there, then Chinese new year holidays with new rules apparently) Get the odd bubble at rest but with the low exhaust you can't have everything.

1. The sorry state of the Hull on the Fire Boat. Purchased from Ebay about 6 months ago, only now just started working on refurbishing it, it was covered in car body filler.

2. After about 2 weeks of very hard work it looks much better. it is running on a Johnson 600 size motor and 6v Gel Battery for its first sail at the Cwmbran Model Society tomorrow, so I hope that is will be OK. it does not appear to be an Aeroits model as the cabins remove from the hull. Not just the Cabin tops. I will try and supply some action photo's later.

This is my Aerokits Solent Class Lifeboat that was rescued from Ebay as a wreck see photo's 1 & 2. This was then lovingly restored for me by Gray (Froggyt996). First he had to skin one third of the hull as only two thirds had been skinned. He then had to use copious amounts of filler to make the hull its correct shape see photo 3, instead of the stepped hull as per the original Aerokits build. He then had to put the superstructure together as it had fell apart whilst being posted to us as it had been put together with a hot glue gun yuk!!!!!! Next started the painting as shown in photo 4. Please see my next post for the next stages of its rebuild.
