Chieftain build by Phil Woollard.

[Kevin Hunter]

Hi Phil

What is the odd plate on left of your turret mechanicals photo for? Looks like possibly another motor mount....., but traverse is fitted to hull, elevation is the screw thread thingy in turret roof and I imagine recoil is via servo fitted in the bracket by the counterweight.

I know I can be a bit thick sometimes but can’t see what another motor might do :oops

[Phil Woollard]

Kevin I believe they call it the slip ring, I also believe it's to keep the loom from getting caught up, I could be wrong as I've not taken a lot of notice of all that lot just yet? Makes sense I suppose. Yes the recoil servo fits into that bracket that holds the barrel.

[Kevin Hunter]

Cheers Phil.

Incidentally, I reckon 0.5mm rubber is too flimsy for the mudguards. 1mm or 1.5mm may do the trick.

I'm with you on that Kevin 1.5mm definately

A very short unedited video of the volume to pressure smoker trials.

[Daniel Brooker]

Just seen the vid looks brilliant Phil what’s the name of the speaker you are using? And where can I get one of those high pressure smokers from?

[Phil Woollard]

Daniel the Armortek speakers are pretty good any ways so think on before you think about changing those unless you want a very loud Chieftain. I can't guarantee that The big speaker won't bugger up the stock amp but we will see.
The high pressure smoker you will need to make yourself using the stock items, I have adapted the two from this kit to make one mother of a smoker. It's not necessarily the amount of smoke that looks good it's the pressure along with it that is most important. I may go into detail later how to achieve this as it's not easy.

Hi Phil
I saw that behind the electric motors (in front) you placed an amplifier or something else. How much can I build from the floor where the engine rests downwards? I can build up to half of the electric motors (i.e. the radius of the circumference). Maybe I could reproduce something of the sides of the engine. I hope you understand what I mean.
Thank

[Phil Woollard]

Basically you could build down in front of the motors but you would not see to much anyway, unless the T piece was removed and the turret turned side ways!
That space is really needed for the modules and speakers.

[Ivano Costantini]

Phil,
I would say to reproduce only at the level of the support floor, therefore only the engine head, the radiators and the refrigerant tanks. So each modeler will decide what the support surface will be like. What do you say?

[Phil Woollard]

I think that would be fine then we have a good amount of usable space below the engine.

[Phil Woollard]

The rubber sheets have arrived and it looks like the 1.5 mm sheet will be the most suitable, it hangs ok and can be bent around the fender corners with ease.

Now this vid is much the same as the previous but from a different angle, the huge cloud of smoke coming from the engine bay is simply spare, or as I like to think of it available smoke, that smoke is leaking from unsoldered joints in the smoker box and the plumbing to the Chieftain exhaust outlets. Therefore we will have even more pressure when I am happy with the plumbing and seal all the joints.

The auxiliary exhaust outlet seems reluctant to give a good signature right now so more work is required there.

I am only using one of the two kit smoker elements, and as you can see there's plenty of smoke, " to much smoke " in fact.

There's also only one smoke box but this is twice the size of the kit box.

Another consideration is the tick over exhaust signature, when the esc has no input the smoker fan has no current, so we have just drifting wispy smoke which looks pants. So we need to add a tick over fan which will provide positive pressure the whole time the engine is running.

There other considerations is with the smoke box inlet and outlets, these you have to get just so or the fan will simply blow the smoke oil straight out the exhaust pipes.

Phil, you're a magician. That vid took me back, you've managed to get the exhaust spot on. Some ex crewmen might also think that smoke from the engine decks is also realistic. It used to happen if the bellows from the exhaust box failed or the liners were going and the L60 had started burning coolant (although in that case, the smoke was white. If you can get the Aux Gen exhaust to work too and sequence it with the start up sounds, you're onto a real winner. Congrats.

[Phil Woollard]

Thanks Stephen, sequencing is the key to be sure, that at present I'm afraid is down to me and my left hand, now if Adrian can come up with the correct selectable auxiliary, auxillary/main engine start up sequences then we have it? That's beyond me! Over to Adrian who has the expertise to solve this conundrum.
