Hi Sam just a quick tip for meshing gears that I've used for years in fine engineering work. A single cigarette paper between the gears when assembling the drive train gives perfect clearance with minimum backlash
That's a great tip but, in this non-smoking world, what is the equivalent of a cigarette paper?
@@gagatube Loo Roll ??
@@keithg1xfl I doubt loo roll paper would be any use - the single sheet stuff might be if it is still available (it also made excellent tracing paper...). I might be imagining it but don't some people say the foil wrap off chewing gum is right for gear clearances? I'd imagine that would be a lot thicker than cigarette paper but I'm not sure.
@@gagatube you can purchase cigarette rolling paper from any tobacconist without actually purchasing the tobacco. The cigarette paper is processed so it is much more malleable and easy to fit around the drive teeth
I know, the cigarette paper trick goes way back! To date, I have never found a worm that was compatible with the gears, so have had to build new gear boxes to match. Also, those nylon worms and gears are brilliant as I recently scratch-built new EM bogies with (central motor and brass universal drives onto Gibson coach wheels) with those nylon worms and gears for all four axles, to go under a second-hand Lima GW Express parcels diesel body.
And you can even add a flywheel, a great idea, especially with a low inertia motor like a coreless one. Splendid idea to ressucitate a shelf queen, I buy it with a 3D printer !
That's a great slap in the face of the manufacturers too : you can have better geared engines with slower motors and flywheel on a shoestring.
I pay the greatest attention to your experiments with 3D printers. My forthcoming PLM 3D printed engines would benefit from this.
An Idea I have : get a complete rodding with laser cut brass sheets... An idea for you ?
agree. flywheel would be lot better at slow speed
I can definitely use this! Maybe my Small Prairie isn't completely dead
Awesome!! Not sure whether this would fit in the small prairie... but you could probably adapt it so that it does! :D
Thanks for watching, Sam :)
ive just fitted one of these motors in an n gauge large prairie and not to much of a problem
Great job, Sam! This will teach the manufacturers. What about adding a flywheel on the shaft on the back of the motor?
I was going to ask the same thing.
I am surprised about not taking the opportunity for a flywheel too. What method do you suggest for accurately meshing the worm and motor Sam?
You're our Robinhood, Sam. Genius work; thank you for this idea!
Hello 'Sam's Trains', I have followed your vlogs for a few years, my word you are a clever 'chap', great to see these older trains coming back to life, good to watch . regards, RichardA.
This is why I think you're great Sam- I love these types of techy videos.
Fascinating and Fan flipping tastic!!
This is actually something I really needed to hear. I have this dirt cheap (probably cost like $30 for the set) loco that had a dead motor in it and it's perfect for me to test this out on. I needed something small to try to learn how to create my own 3d parts and I think this is perfect. Well done Sam and I'm glad to see you've taken to 3d printing.
Hi Sam!
Great vid, how about making your own flywheel for the back of the shaft, see what that does to the performance?
I've used these (13.5k) motors in my P4 Metropolitan locos, and can confirm they really need a small flywheel, and running-in before they crawl properly. Hadn't thought of using them as replacements in RTR models. Well done.
Nice job fixing these locomotives and saving them from getting scrapped by the scrap monster! 👍
Great video once again! I was thinking….. you could create a 3d printed object that fits into the tender of the 9f that many suffer from mazak rot and disintegrate. You could make it so that it clips into place (like the old ringfield enclosure) whilst allowing it to hold the electrical pickups and the wheel axels. This would help a lot of people such as myself whom have a dead 9f due to the tender ringfield enclosure turning to dust 😁
I love these kinds of How-to videos, Sam. This was great
Nice work Sam, Iv'e done something similar for my Triang Jinty and a old pocket rocket 0-4-0 Blue '7178' getting hold of the motors here in Candida is near to impossible and shipping costs from England are more than the hornby/Triang motors, so I used a mini 6 pole motor yes 6 pole from AliExpress for $5 CND about £3. They work better than ever, Its slowed down the 0-4-0 and now can crawl, both loco are great shunters and seem to have a realistic top speed at about 10 volts.
I look forward to seeing more motor swaps.
I'd love to see both engines perform with different motors
That's interesting! Do you have the link for these motors? I also don't live in England so it's nearly impossible to get them
I've seen those motors advertised for a few years now, and have often wondered.
I tried fitting a Pendolino 5-pole, or Castle - forget which - motor to replace the hopelessly performing Bachmann Jubilee I had at the time ...
My problem is I don't have a 3D printer, but it NEARLY worked, with a motor at least twice as good ... would have been a nice fix!
Great that you're giving the Community additional ideas Sam.
Thanks for sharing.
Al.
Thanks Al - you can get great motors very cheaply these days - I've almost never been disappointed! Appreciate it anyway,
Thanks for watching, Sam :)
I'm just happy it stops Bachmann ripping people off - one of their favourite activities in my experience!
Companies are suppose to make money. You might have mistaken it for a charity.
@@macnavi There's "making money" and then there's "extortion"... or just plain old "gouging". Bachmann designed things such that you had to go through them for replacement motors without major alteration work, and then charge significantly more than the value of the product (which they are already masters at for all their products).
It’s probably a bonus having that back shaft on the motor, depending on the design you might be able to fit some sort of flywheel
Maybe a small flywheel could be fitted onto the other end of the motor
Yeah absolutely - one that's narrow enough and with a 1mm hole would be perfect! :D
Thanks for watching, Sam :)
@@SamsTrains i'd imagine that the rotational mass of the motor is so low that even a 3d printed flywheel printed at 100% infill would yield beneficial results!
@@SamsTrains wouldn't the flywheel need to be balanced to run properly?
These motors are very low torque but high speed. Adding additional mass to the larger wheel would be more beneficial.
With a lathe, a flywheel would easy. But even if you got one off the net with a bigger internal diameter . You could 3d print a bush for it.
Incredible how small the motor is, I think it needs a flywheel to smooth out the action
Lathe time.
Oh, i Did not know Leo watched this
Awesome repair! You know, there's plenty of room on that other shaft to install a flywheel.
Bachmann management meeting Monday morning..."The assassins failed again?" LOL
Always nice to have options 😊
Really great episode Sam, fantastic to see your channel really adding solid value to the undertaking.
Best regards
Great Sam, just love your ingenuity
Great work Sam!
Very ingenious Sam , well done .
17:20 Imagine seeing a locomotive run while it’s like that lmao! 😂
This video & your free design are a great service to the MR community!
I often bought broken / in disrepair stuff from train Star wars and antique stores and train shows whenever I was a child with my grandparents in order to save money it was also fun for me to create Frankenstein locomotives using various different parts that I had it really did put me to the test to see what I could build and put together with my limited resources and knowledge
this guy is a frickin legend
A genuine mastermind at work, brilliant. As many have commented previously, but indeed even adding a flywheel could perhaps be done. We are also wondering if even a brass worm drive could be found. Next… knock, knock, “We are lawyers of Bachmann…” Lol, just joking. A genius solution Sam :)
You could put a small flywheel on the back shaft.
Great video Sam! Very innovative with that printer.
Amazing job Sam
I've been working on my own motor housings for the Bachmann thomas range for a while now. Recently made one for Edward, also made one for toby. Then I've also designed some for Thomas and Percy. I plan on redesigning Thomas, and Percy was designed for just the chassis without the top. All excluding the gearing for the eyes. I can share the finished design with you if you want to try them out. Though they use the Bachmann motors, you can always design another fitting to work with the motor you used here.
Great video Sam, I wonder if it would be possible to adapt a motor similar to this to get an old Triang 156 emu working again with the use of a worm drive on each end of the drive shaft?
Thanks Sam. You are making some very interesting videos with your 3D printing and painting experiments. Of course, your loco and trainset reviews are also great. I have N scale, but I am thinking of trying the Hornby HM6000 bluetooth controller which seems very interesting. I believe it should work with my N scale which is a 12V DC system. I will let you know. Cheers from Canada :-)
Great idea. This is the future for giving old locos a new lease of life when new models are so expensive. I'm looking forward to the time when I can buy adaptor cradles that allow you to replace x03 and X04 motors with coreless or 5 pole motors.
Why my X04 and X03 motors up to 55 years old run fine and are serviceable.
@@fenman1954 I do appreciate that some are still wonderful runners, but the ones I have, though, I have cleaned them and oiled them and replaced the I magnets and done all I can to make them serviceable, they are not good runners at all. As you cannot buy new ones there are no guarantees second hand replacements will be any better; they could even be worse. I'd like to give these locos a new lease of life.
Brilliant Sam, it's about time somebody showed these people we are not all cash cows. No doubt the rivet counters will have something to say. Keep up the great work. Frank
Decent bit of work there Sam seems to work great, I must say though the only bachmann motor I have had to replace is the virgin voyager and when I bought the motor I got 2 of them for a decent price, I have never had to change a bachmann steam locomotive motor.
Thanks for sharing David - that's very good news - I don't wish motor replacements on anyone, lol! ;D
Thanks for watching, Sam :)
This was awesome. Love your chanel.
That is bloody brilliant Sam nice one 🙂✌️
Awesome video today Sam love the idea you should try and fix some of your Bachmann Thomas locomotives with burnt out motors and do a video on that
Thanks James! Though some of the Thomas models do use these motors, they're mounted quite differently... but sure, some kind of adapter could probably be made for those too! :D
Thanks for watching, Sam :)
Great tutorial to resurrect dead Bach. locos. Some 'Master' here calls you 'our Robin Hood' and I join his comment ! Thanks for sharing this interesting video Sam.
Great job ressurating great old locos.
Brilliant Sam.
well done young chap. more proof of a bright future
one thing you forgot. this is recycling and green well done
roy
Great stuff Sam that's a decent how to video thank you :)
Thanks a lot Michael - glad you liked it! :D
Thanks for watching, Sam :)
Thank you for releasing things to the public. :)
Just ordered my Model Train Enthusiast shirt...super stoked to get it and represent here in New Hampshire!
Well done !
Hi Sam I did experiment with my Hornby 0-4-0 tank engine I put a Bachmann motor I'm my Hornby 0-4-0 and I have to say it worked
Meanwhile at Bachmann headquarters the R&D department are having a meeting.
"We have news that someone has figured out how to repair and improve our locomotives without using our parts. We need to download those files and make the parts and replacement motor more expensive".
Good idea Sam, it's a shame that there aren't any small metal milling machines to create a metal worm drive. It seems 3D printing upgrades is becoming a popular idea now as Peter's Spares does upgraded gears for old Lima motors and detail parts for locomotives. They have also done some upgraded non traction tyre wheel sets for the old Lima and Hornby DMU's and diesel/electric locomotives.
Sam, this is an excellent fix, well done! - Especially with your motor adapter and because you gave a source for the worm gears and even the screws needed! 😃
The only potential downside I could see is the longevity of the motor, particularly since it is completely enclosed and covered by the adapter so there is no chance of cooling. But then that design may not need any... only time and lots of usage will tell. ⏳
thats the differance between a model mechanic and a model engineer engineer makes its so the object works the mechanic just fits bits you buy from stock shops well done sam for this 1
There used to be a motor called a Romford Bulldog, which was a 5 pole drop in replacement for the X.03/4. If only they were still available, and something similar for Bachmann models too of course.
Another great video.
I can't wait to try this because I have 3bold engine a pannier, b12 and n2 which all kinda short circuited my layout so I hope I can get this to work
Well the B12 and N2 aren’t Bachmann locos - unfortunately this will only work with certain Bachmann steamers... but you could use same the idea for almost anything!
Ah well thank you for the heads up
Love this ive got a 5 pack of these with the one sided 28000 rpm option from either ebay or aliexpress which was under 10 dollars usd. Good to see how they run! I wonder if a larger diameter worm gear would slow it enough to factory crawl speeds and smooth out the action abit.
Love these types of videos, if I ever have a issue with Bachman I will def look at this video. Keep up the great work
Awesome David - it's here for you if ever you need it! :D
Thanks for watching, Sam :)
Really interesting little project 👍
- if you just chose fairly cheap motors for you demo here, and they were pretty servicable, i wonder if there are better motors available that would be a proper "hardware upgrade"?
Another thing that i thought was you seem to suddenly have space to pop in a tasty little flywheel (assuming you can buy these off the shelf?)
The possibilities are endless! 😀
amazing watch,thanks for sharing.
I'm glad you were able to devise a motor replacement for Bachmann steam locos. Could you possibly make a motor mounting for diesel loco models?
hi sam. i missed watching your review about the new rebuilt hush hush on the day. a great model for the price you paid for it. but i intend to stick to my guns and not buy models with out of this world prices. true i am missing out on new models. another great fix it cheap video... no whirring buzzing or squeaky noises ... would be a great fix even for new bachmann models which lack the umph in torque.
good vid on the channel thanks lee
Nice work Sam :-)
A good project Sam, did you do a torque test with the new motors for coaches on straight & level track ? it would be interesting to find out .
I love the safty advice on the pack of Laptop repair screws.
Yay! Although not bachmann, I believe I can finally cheaply fix my Ruston 48
Oh awesome! That still might be tricky though - not much room for manoeuvre in the Ruston 48!
Thanks for watching, Sam :)
the shaft protruding at the back end is a great place for a flywheel
i replaced the n gauge original motors by coreless 7 mm diameter motors in dapol steam locos.it is an easy job because the motors are in the tender.no need to dismantle the loco.result:best quiet performance and even better enough space left to install a zimo sound decoder + sugar cube speaker.now i have the amazing reality operating fun.
well done !
Great idea! Any links for that replacement motor? Seems small enough for some of the stuff I'm working with.
You can get them on e bay. I bought a bunch last week for $1.50usd last week for a different project
Hi Sam. I've got a challenge. How about a locomotive with an n20 geared motor? You can get a 12v one off Ebay really cheap with a 1200rpm maximum speed, but it has a tonne of torque because of the super low gearing. Might make a really awesome shunter, would also probably be super loud though.
If the motor ever dies on my B-mann 9F, H1, or Super D, then I will definitely keep this replacement in mind. I've had the 9F apart to remove a blown capacitor and offered up some spare HO motors I have on hand (Bachmann 5-pole, Kato, Atlas, Canon) but all are too big. The 9F itself has a mounting cradle made completely of metal so the 3d-printed coreless mount might not work in this case.
Another option I've considered is the 5-pole motor found in Atlas' N-scale diesels. They are very high quality and I've found an eBay seller that has them for cheap.
What do you recommend for replacement of the old Triang/Hornby X04 motor?
If you want to improve crawl why not try a gearhead motor? You can get tiny ones not much longer than this motor. This would also improve the torque that was lost by using a smaller motor diameter. Great that you are sharing the files Sam. This is how the 3d community has worked over the years. Cheers Gary
Love the look of this, Were you going to post a link to the motor you used? I had a quick look on Amazon and most of the motors I saw seemed to be about 4.5V, as a DC Model railway transformer goes up to 12V, won't that fry the motor pretty fast?
eBay is a better bet for motors, put "12 volt electric motor" in the search field.
There is also a Mabuchi FT-010SA-07300 3 Pole 1.5MM drive shaft on eBay that looks very similar to the Bachmann version.
I wonder if it would be possible to make an adapter to fit different gearing to help with slow running as in many small locos they run too fast and have poor crawl performance.
Great video will you be repairing your Bachman Emily with one of these motors.? Thanks to you I can now repair most of my old Bachman engines . Your a good man Sam.
Sadly not - the Bachmann Emily uses a different kind of motor (even smaller) but hopefully there are a good number of locos that can be fixed this way! :D
Thanks for watching, Sam :)
Did you compare the pulling power of the Bachmann 3 pole and those coreless motors?
I've got a couple of old Bachmanns that struggle to pull more than 4 coaches. Maybe they are on the way out already.
I'll be getting a few motors regardless. Thanks for the info and the basic adapter.👍
Brilliant!
I had almost given up watching your channel this is one of your better videos.
Well thanks for sticking around David!
Thanks for watching, Sam :)
The issue about the coreles motors is that they are not always friendly with decoders. I fried a couple of decoders trying to have a Japanese Tsugawa Yokou N scale chassis with a coreles motor run on DCC, I even used ESU decoders that were recomended for coreless and probably ran fine with larger coreless motors.
Nice sam ingenious, a poke in the eye for rip off manufacturers 😃
That looks to save a lot of space for DCC stuff in the loco - when converting non DCC locos :)
I'm building 2 custom RWS version models Gordon and 87546 I definitely need this bc I'm gonna be transferring motors from different engines
Hey Sam. as someone who printed some stuff myself, I would like to kindly ask you to release your designs individually. I saw you have a short and tall base variant, it would be nice of you to release each base and the top part all individually. I know, it is 3 files then, but it would be nicer if someone needs a spare and not print a whole new adapter. I'm not angry, I'm always thankful for everyone putting in thought and work on these little things.
Thanks for the vid, I've ordered a motor but I can't find the worm drive to take a 1mm shaft (the ones on eBay are for 2mm shaft). Do you have a link for these?
This is a great video
Hi Sam in helpfull response to those who have requested adapters for X04 type motors replacements can be found in rummage boxes at swapmeets and a full refurb by Scalespeed who do a very good job.On the Bachman motor issue I have remotored several non split chassis locos with the appropriate Mashima 16xx series motors resulting in vastly improved performance only the removal of the original worm proving difficult but worthwhile.
Great work Sam, but for those without a 3D printer, would you object if I got some printed and put them on eBay?
Best show on the internet. If you can find a 5 pole motor, that should solve the croul problem.
haha thanks so much! The trouble is space - the original motors are more or less an exact fit into a Bachmann body... and those motors are tall and thin... so picking something tiny increases compatibility across different models!
Thanks for watching, Sam :)
You could fit a flywheel on the unused portion of the motor shaft if the loco body has room. It may improve that motor somewhat
6:20 Of course, if you have a 3D printer, like you were talking about earlier, you could make a custom gear puller.
@Sam'sTrains You could add a Flywheel to the other end of the motor!
Out of curiousity, would it be possible with this one to add a fly-wheel?
Hornby mallard: I’m fast as fu*k boiiiiii
Bachmann LMS loco in this video: someone hold my alcoholic steam oil.
That's really good Sam, Did you get my feed back regarding the re-built Hush Hush
Great Video (As Usual), a Question - Where did you get the Motors? I found a few on Ebay but they are 3.4V and the !2v ones are 15 Quid A Pop
I was just wondering if you could add a flywheel to the other end of the shaft. Maybe resin some washers together or file down a worm gear to give you a central core to affix washers to.
You need inertial mass anywhere on the gear train to improve performance. These motors are so low torque a flywheel would not be effective. It would be better to add more mass to a downstream larger gear.
