Mark,
I'm interested to see your recommendation of XTC-3D ( I know you've mentioned it before).
I have considered it for my own prints and it seems to be hellishly expensive, but it's difficult to get a feel for how much is actually needed. How much would you say you have used on this loco, and guestimate cost if poss?

Hi Philip

Good question re XTC-3D - I've just looked at the two bottles the product is made from (you mix the two parts together for it to activate)

I'd say to do the Hunslet and the cab of my other build (so lets say 1.5 small locos) , I've used one sixth of the product. So at that rate of usage I'd suggest you get six per small bottle at least, maybe eight if you employ the product carefully without any spillage/wastage.

I bought the smaller (6.4 oz or 181g in new money) of the two bottles on offer at 4D Models - https://modelshop.co.uk - which currently retails at £13.50 - however P&P is relatively expensive ( I think it has to go via a more premium service because of what it is - deffo wear gloves when using and use in a well ventilated room!) so P&P was about a £5 - so in total £18.50

Working on six small locos, thats about £3 a loco which I think is not bad

I think its good for bigger things where you want a nice flat smooth surface (locos, coaches etc) - for some of the smaller more intricate items you produce, you might find a well used piece of wet and dry and a needle file equally as good.

Hope that helps - shout if you have more questions

Cheers

Mark

Congratulations, that loco's a beauty!

I'm not much of an engineer, but I must admit I'm tempted - slate wagons kind of need a quarry Hunslet to pull them... And if they continued their Ffestiniog range with an England I think I'd be even more tempted...

Any idea of how powerful it is?

Well done on a lovely model,

Andrew.
Hi Andrew - just sorting my battery issues out so will reserve judgement on power till its working properly - I have seen other peoples locos on YouTube pulling good length trains - may need extra weight to maximise that - will update once I have the power working right

Excellent, thanks, I look forward to hearing about it.

Good luck with the electrics,

Andrew.

After a bit of fettling with the gears and a rechargeable 9v battery - we are getting there - a quick video of No6 on trials at the CHLR

That's running much better now Mark.

I would of thrown it in bin ages ago so I admire your determination to get it working!

Tom - there has been a lot of swearing involved!

Its annoying when you build a great model and then you can't get it to run - I'll report back on how long the 9V rechargeable one lasts after a few tries - may have to get creative with my battery block shapes if I end up back at 4 AAA's like use on the other RC locos. Someone on the 16mm facebook site has managed to get 5 AA's in there - my challenge is that whilst popping the DPDT switch under the boiler hides it away from sight, it does mean the backend of the switch sits inside the boiler, making a bit of a nuisance of itself when you are trying to cram batteries and deltangs and spaghetti wiring in there!

Do you have to have a FB account to view the 16mm group (this is not the Association one is it?).

Pleased to see the rechargeable PP3 seems to have got it moving ok. I'll be interested to hear how long it lasts on a charge.

Cheers Rik - yes I'm going to test it over the next few days and will report back - managed 10 mins tonight but was stopped when the worm came off the motor - oops blame the builder for not tightening that screw up properly :oops: - to be fair thats the furthest its run so is just a bedding in issue - back to workshops Wellington goes!

For any given battery chemistry and battery volume there is a trade off between voltage and current.

NiMH 9V rechargeable batteries are low capacity, about 200mAH, compared to around 900mAH for the average AAA size 1.2V NiMH battery. The 9V rating is fairly nominal as well, usually closer to 8V in practice for rechargeables.

I've no direct experience using 9V rechargeables in models, but if the motor in Wellington has a typical current draw you should get about a 1 hour run I think, more if the motor is a low current type. I get +4hrs out of my works train using 4xAAA NiMH cells and a simple electronic speed control.

Regards,
Graeme

Cheers Graeme - thats a good benchmark for me to test to - I agree my AAA's will give a much long runtime and i may end up with those as a solution but the space in the boiler is limited so thought I'd try the 9V approach as that fits JUST nicely into the space.

When I have re-fitted the worm, testing can resume!
