I got one for my Aristo Mallet but it would not fit in the boiler, just a little to large. So I put it in the tender and ran a black hose from the tender to the stack and it works great. It runs under the cab so it looks like a coal feeder. To be able to seperate the tender I cut the tubing and slipped in a small 3/8 length of brass tubing to act as a splice. I get about 45 min on a fill and about 4 foot plume of smoke wind or not. Jake

www.harbormodels.com look under hardware then smoke unit

Looks like it's a bit pricey. It does put out the smoke tho. later RJD

Well, MTH just took second fiddle!

That is huge... 2 amps at 12 volts though, that's too much current for the battery guys.

Yeah two amps seems high draw. But then what kind of batteries are those boat models using?

This new smoke unit would be even better with a chuff puff sync feature. Probably not going to happen given the intended model boat market.

Well I may just bit the bullet and buy one and do some test with it and see what I can install it in. Just a little concerned tho about the amount of current it draws. Later RJD

I too looked at the harbour freight product and again the current draw is worrying.However, looking further into the model boat scene I Googled Model smoke generators and came up with loads of interesting stuff,some quite frightening!Some of the guys in the boating world are using mist generators with great results,these use a fast oscilating ceramic diaphram to produce a water mist.The downside so far though is the depth of reservoir needed to work the thing but maybe a thing for the future,

I tested with the amp/voltage meter I got from Tony's Trains and if its accurate at 18v it draws at .87 amps not two that it says on the web site. I use a constant 18v and all engines have QSI/G-Wire set up. I want to do a kit bash and add a second stack to the mallet the volume of smoke I get can handle it. Jake

Well that info is a little better. So I will order one and Yep I'll figure a way to install in the boiler of the Mallet. Later RJD

Please let us know what they say about a chuff feature
Here's what I sent them:

Questions:
1. Does it shut off when the fluid runs out?
2. Can you mount it at an angle (e.g. sideways,) i.e. is the tank almost sealed?
3. Do you think we can make it "puff" by triggering the fan intermittently (with pulses) ?


Here's what I got back from Harbormodels:

The unit will not turn off automatically when the fluid runs out.
It cannot be set at much of an angle as the fluid will get into the fan
If the fan is turned off for mom than a few seconds, the unit will melt

Considering the power requirements, the amount of fluid and the heat generated, it would seem that this particular smoke unit would be more suited to a high-end brass engine like an Accucraft. If something were to go wrong and the unit melted, a plastic tender wouldn't have a chance whereas the brass tender would survive.

Yes that would be a concern of melting the boiler also. Not much of a price difference between the Harbor and the Massoth units. Lets see if anyone has bough the Massoth and tested for volume of smoke. Later RJD

Ive got one of the Massoth units on order for my AML 0 6 0 that has a QSI card in it. I cant use the MTH units that i like so i hope this one will smoke decent? is a bit pricey.. i hope it doesnt take LGB smoke fluid, that would break my bank

I saw a Massoth working at the NGRC in Denver. It looked good, but not as much smoke as the unit that started this thread. It does have the sync'd chuff and puff, which was very nice. Can't remember if it had specific fluid requirements.
