- Hi everyone, in this video I'm showing how I fitted the "HM7000-8TXS" sound decoder into the TT Gauge Class 08 by Hornby. There's also Hornbys Power Bank module and few other things for good measure, such as lights and a flywheel.

Absolutely amazing. I wish I had the skills and confidence. I’m waiting for a steam shunter
Id recommend maybe practice on something else first but anyone could do this if they wanted, its just doing it alot that makes accuracy better, im only human, yeah cant wait to see what Hornby brings out as a shunter steamer 👍
Are you confident that the removal of the, screwed down, top motor housing clamp assembly and adhesive used @ 6:03 in its place, I take it to get the sugar cube in, will be enough to hold the motor in place with varying torque forces imposed and heat generated, running over longer periods, jams and different loads. That said, fabulous innovative work here!
Im happy with the adhesive choice in the video, that being said i actually make these very differently now, either way the top peices are still in the way so get removed 👍
@@ThisWayWorksTWW Thanks 🙏 It’s a superb look and totally understand the progression as you proceed. Keep up the great work and innovations ❤️
Madness. Wonderful. Excellent work, and here's me wondering if I should do the same to a OO Gauge Class 08
You could probably use the same power bank module i used in this video TBH 👍
@ThisWayWorksTWW I have the TXS decoder and stay alive. I sat waiting for me.
@@dinmorejunctionmodelrailway im not familiar with the 00 version but my first point of call would be see how others have done it, then id pull it apart and see how best you can fit all the bits and bobs inside, it can sometimes be a bit like a Japanese puzzle 😁
@ThisWayWorksTWW I've watched Piccadilly Model Railway installing Hornby TXS Sound Decoder in a OO Gauge Class 08 but what you have achieved is excellent.
@@dinmorejunctionmodelrailway thank you, i do it a bit different now as i cut the bodies less (this is a very risky thing to do). I cant help but modify things 🤣
Great work!
Once more, amazing :) :)
Cheers dude👍
Can you please give me an estimate on the cost of this conversion?
I have the Class 08 and HM7000-8TX
Thank you
Ps. Great video BTW 👍
Yes just drop me an email at baylissbespokedesigns@gmail.com
Top job TWW & thanks for the shout out 😊
I owe you alot of shout outs mate👍 thank you
Peaches and cream. Wow… this video has literally blown my socks off
@@modeloco but it was "only supposed to blow the bloody doors off" 🤣
@@ThisWayWorksTWW Brilliant reply yes 😂😅🤣 I’m gonna have to get an 08 now, it’s officially been done. Got my wallet scorched rushing in before. You make this pioneering look effortless 🙏
@@modeloco i do make these now albeit slightly different to the video, my emails in the video description if you did want to get in touch 👍
I would like to see any of them. But would choose class 90 first.
Great channel. 👍
Cheers Mike, so far its definitely between the 90 and 122.. heres hoping i can actually fix them! 😅
Hi, superb work on such a small loco, Hornby have never fitted lighting to the class 08 00 gauge loco, they want a very high price for it though, Bachmann are the same although their class 08 is cheaper, I hope Accurascale produce a class 08 in the future, I believe it will be the best in class by a long way, have you seen those lighting diode boards for lighting? Thanks for sharing with us.
It is a shame they dont fit lights as standard. Yes i have seen diode and resistor PCBs however some of the time the PCB takes up a bit too much space 👍
great mods, so is the tm-07r a complete chasis kit that get used instead of the br chasis? or there some sorta motor swap goin on or is the orignal motor just transferred to a new chasis maybe? thx ill rewatch tho.. can the stay alive be used without a decoder to help like you said over insulfrogs?
This stay alive i used i believe can only be used with the hm7000 decoders. Think its a voltage thing... The Tm-07r is a tomytec chassis i had and used the flywheel from, i just used the flywheel from the complete chassis as a donor peice for the 08 motor. You dont need to add a flywheel really but i could so i did. You can use other stay alives and decoders out there but in my case i wanted the Bluetooth connectivity and sound so this was my only option 👍
I have only fitted stay alives to DCC locos.. essentially the decoder controls the stay alive.. thats the easy way of saying it wouldn't really work as wanted if you used a stay alive on DC.. so no for DC but yep for DCC 👍
ah great info so if i wanted to just chuck the hm7000 in with no flywheel have you got the schematic for the decoder wiring to the loco, im assuming its 6 pin and you soldered direct in some way? and you chucked an 8 pin decoder in ?@@ThisWayWorksTWW
@@kool-k-kel its the 8 pin HM7000 decoder i used. The loco needs a fair bit of fettling for all the bits to fit.. you can just wire up the pickups and motor which would be 4 wires..
any chance of a pic or quick pinout?@@ThisWayWorksTWW
Hi Richard, You have done an amazing job on that. If I just take the straight 08 and fit the 8 pin R7336 would that work? It was difficult to see which wires from the decoder go to the train. I don't really need the lights or stay alive. Happy to use a soldering iron and make it fit, it's just the wiring that's confusing me. Hope you can help.
Ok so if you pause the video on the schematic, you'll see all the lights... The 8 pin plug shown on the schematic is what the R7336 is.. red and black wires go to the pickups of the loco. Orange and grey go to the motor. If you just wire those four wires then you loco will work. Because the loco is small id recommend fitting the stay alive otherwise it wont run great at slow speeds. What ive done in this video is hardwire the decoder into the loco. That just means i cut the plug off the decoder and soldered the wires to the pickups and motor etc
If you do this and the loco runs backwards then just swap the motor wires around👍
Hopefully this helps, you can actually use the Hornby TTS decoder wiring to wire the 8TXS, same wiring 👍(8TXS has an extra purple wire for lights)
I had to use a dremel to allow the decoder to physically fit above the motor and inside the body, this is the risky bit
@@ThisWayWorksTWW Thanks Richard, that is exactly what I wanted to know. Thanks again & great job with yours.
How do you fit a 8 pin sound decoder into the six pin socket the class 08s have? Tyia!
The six pin socket is removed at the beginning of the video and then progressively the 8 pin decoder gets hardwired into the loco, cheers Rich
@@ThisWayWorksTWW ahhh nice one, thank you :)
Hi. I was wondering if you'd made any changes to the running profile? I have just done this conversion myself, thank you for the tutorial. I uploaded the 08 sound-set and profile. However, mine will not run correctly. It sort of speeds up and slows down, regardless of speed setting and it constantly loses power/connection. I didn't fit the stay-alive as I wasn't confident grinding away at the chassis. Do you have any ideas? Thanks again for the video. I wouldn't have attempted mine without it.
The speed up and slow down sounds like acceleration settings and deceleration settings, set them to 0 to have quick responce👍, the other issue with constant connection issues sounds like bad pickups, oily wheels, lack of stay alive. This is assuming your volume is not set higher than 20 and causing the decoder to brown out though.. have a look at all the things i mentioned, you can get them to run nice ish without a stay alive however everything including the track has to be flawlessly clean 👍
@@ThisWayWorksTWW Thank you. I will make those adjustments tomorrow. I have my volume set fairly low, but I'm wondering if my lights might be causing too much drain. I didn't have any 15k resistors so had to use the ones that came with the leds. 1000oms I think. If I hold the loco still it will run and I did put it up to full power with no issues. I may have to be brave and take a dremel to the chassis for a stay alive. Thank you for taking the time to answer.
@@Froobyone the lights flickering indicate more to me you have a pickup/dirty issue 👍, i use between 15k and 22kohm depending on LEDs really.. on mine the lights can flicker when it starts to get dirty even with a stay alive. Give it a really good clean and it should not cut out so much 👍, the decoder can supply around 400ma on the outputs combined so your LEDs should be fine there
@@ThisWayWorksTWW I'll give the wheels a good clean tomorrow with some isopropyl. I did give them a clean earlier tonight with a dry cotton bud and they were filthy, but it won't hurt to give them a better clean and the contacts on the wheels. Thanks again. :)
@@Froobyone no worries, good luck, the stay alives completely change the way the locos run so by default now i always try my best to fit one. Let me know how you get on 👍
122 please! nice work with the 08.
Thank you👍 thanks for the vote too 😄
Hi Richard, Excellent job with the 08! great bit of shoe horning 😁. Have you experimented much with the HM7000? just wondering if it will still produce sound properly without it being hooked up to a motor, I've been told it should work, but had no real verification that it will. As for locos I would have to go for the Class 90 bit more of a challenge especially if you are adding lights🤣🤣 All the best Tony.
Haha Tony i need a bit of a break from LEDs atm 🤣 interesting point with no motor will the decoder still work, i have a loose decoder to play with, will check that out 👍, there pretty much a TTS chip in form factor, same size pretty much. The 8TXS and NXT18 PCBs i beleive are the same just one with a socket and one with wires.. if i test the motor out il let you know👍 take care mate, Rich
Class 90!
Excellent choice 👌
122 thanks matey!
How does one contact you for commissions
You can drop me an email at baylissbespokedesigns@gmail.com 👍
Would you be able to do the same to my 08 shunter please
Hi yes i do commissions, you can get in contact with me via baylissbespokedesigns@gmail.com 👍
Hi Richard I cannot believe what you did, so tiny beyond me. Also why didn’t Hornby make it easy to add some to the 08. Please repair the class 122. As it’s on my list be interesting if you could add sound!. Cheers Roger
Cheers for voting 👍, yeah it would of been great if Hornby had at least left chunks of metal off the chassis for more people to fit sound, maybe in the future they will bring out a Zimo sized chip🤷, il see what magic i can do on the 122 if she wins👍👍
@@ThisWayWorksTWW look forward to the 122 cheers Roger
122 next please , the upgrade on the 08 is very impressive , I'll leave mine analogue though [ ham-fisted coward that I am ]
Good choice 👍, i wish id of left mine analogue too, it was a journey fitting the bits and bobs in it 😂
@@ThisWayWorksTWW 🤣
Class 122 please :)
Brilliant job. You could have a career in brain surgery... Blue Danube was an added bonus. Class 122 please
Thank you, i think she needs a bit of weathering tbh, dirty her up some😂, got your vote for the 122👍 thanks
What could possibly go wrong?
One slip and game over TBH but at the time it was the only way, hence the intro lol.. best way is putting a coreless in it, then you dont have to cut the body as much 👍
unfortunately this beyond me but i can now put a driver in the cab now i know how to get it off.
Its just alot of practice really, i am doing commissions if thats something you may be after though? Some cabs are really stuck down and some arent to bad, good on you for getting the cab off 👍👍 cheers Rich
@@ThisWayWorksTWW thanks rob
Hi how much for commissions?@@ThisWayWorksTWW
Would you do this for me ? I would pay of course , let me know 😊
