Hi Roger,when I was disassembling the original set up, they were fixed in place via a cup holder which in turn has a thumb screw to adjust the speed at which the original set up could work. Fortunately ,these have flat bottoms, so roughened them up before fixing to the hull with adhesive. Bonus side is that being metal they also contribute to the ballast. So that accounts for the 3 larger gears. The 2 smaller gears are held in place by the plastic handles that were part of the original setup cut down to size. The 2 smaller gears serve a dual purpose of not only acting as spacers but also ensuring that the larger gears turn in the right direction. A bit of a long winded answer to your question, hopefully you'll still be awake by the time you've reached the end of this 😁

Thanks for the reply still awake, a good description.It was obviously a very good find. And as you say they will all turn in the same direction. Like to see the finished result

Four AA alkaline primary cells shud yield 4 to 7 hours operation at the 0.4Amp draw of the "smoker". I agree it's the simplest approach. I have several models where a pair of AA's power my navigation lights.

Our sailing site, Bluffers Park in Scarborough (the Scarborough in Ontario, Canada, clarifying for website members in other countries) has a "soft close" of parking at 7pm so this summer we have not done any night-running sessions. Perhaps in autumn tho when Night descends earlier??

Hi Bill,
You're right😌 Old habits die hard!
I have suitably modified my post.
In future I shall try to refrain from posting in the middle of the night
or waiting up til 2am for the the new QotD💤💤💤

Ref photos: as previously posted the smoker from Hotspur that I described in some detail was removed during a major refit some time ago and went missing after two house moves. I will have to rebuild it.
The other, newer ones I bought recently have only been used for bench testing so far, and searching for the ship modellers holy grail of black smoke. The search has thus far been unsuccessful☹️ Some of the most recent units with larger reservoirs and fans are still in the boxes/bags.

So over to Chris, he has the info now
Cheers, Doug.

Cheers Bill, I've got an idea of using a carcass of a marker pen as a sleeve over the top of the smoker into the funnel and hopefully contain any condensation from running back into the hold 😀. Maybe if I get chance today.

Well done you for having the patience to deal with all the detail on this boat. Looks good to me ! 😉

She is going to be a very nice ship when your done mate, brilliant job!

Chris.
Looking really good.
All your hard work is paying off.
Regards
Bill

Chris.
Good to see steam up 👍.
I know the feeling re lack of space so good luck trying to get it all in.
Look forward to ghd next installment.
Bill

Enjoying your posts and hope that things are progressing easy…looking forward to more of this great build , Thank You …..
Bill G.

A fine job Doogle👍
A majestic masterpiece.
And in only two months or so!😮
Looking forward to her trials.
KUTGW,
Doug😎

She is looking awesome, 👍 and very inspiring for me to start my own kit but current situation does not allow me the pleasure of such a long term detailed project. I have foolishly started my first semi scratch build and already have had to many distractions. I will soon start the build blog , but for now am very much excited to see you fine efforts having a great first sea trial and many happy smooth outs after … Again Thank You
