IP Engineering 0-6-0 chassis build

Post by Johnnie1000 » Mon Sep 14, 2020 11:20 am

Hello all, bit of a long shot I think. I have cobbled together enough bits to build a chassis out of IPE/LC models bits and pieces. Just enquiring if anyone has any bits for IP Engineerings metal shunters they dont want. Cab sheets bonnets castings etc. Like I said long shot but you never know. If theres nothing available, I will have to let my imagination run riot. Thanks anyway!

No bits here, but just wanted to say I'm looking forward to seeing what comes of the project.

Hi Johnnie, yes likewise here - interested to see what will come of this. It's a really substantial looking chassis. As someone who is (in the very, very early stages of) learning to work with brass, why not have a go at scratchbuilding a body for it?

Looking forward to seeing how you get on anyway. Thanks for sharing.

Well, Time flies. I have progressed my little loco on a bit. I have asked around, and IP tin shunter bits seem to be like the proverbial rocking horse poo. I will therefore, have to put a body of my design on it. (Possible disaster alert.) I am now trying not to let it cost me anything but I will probably have to buy some Plastikard, MekPac and (definitely) screws. Brass Tom, is a bit scary for me. But you never know!
So far, I have removed the gearbox as it was not up to the job. The wormwheel is fitted with a 12BA x 1/8” slotted head grubscrew, tightening this with any force at all results in the screw slot splitting and it still not being tight enough to attach the wormwheel to the axle to drive six wheels. I did consider Loctite (the blue stuff), but you risk gluing the lot solid as the wormwheel is captured by the 3D printed gearbox. What I mean to say is that the assembly would have to be glued in situ, therefore there is a (high for me) risk of getting glue on the bearings in the gearbox. I will find a railbus or some light duty vehicle to use it in. I managed to get one of those Indiana Jones Lorries (you know, the German thing with the “canvas” (plastic) cover on the back) before the prices on EBay went potty. It might be a fit in there for its use on rails.
Instead of the proposed gearbox, I have used my usual method of a Slater’s wormwheel assembly, 4mm/2mm coupling and a MFA 15:1 Motor gearbox. (Yes, these were in my bits box, for a long abandoned idea.) I thought I had a sheet of Aluminium to make the footplate, but I couldn’t find it, so I have used some 3mm Plywood, braced with 10mm x 10mm x 1mm Aluminium angle iron (the (6BA) screws are in temporarily until I can get hold of some shorter ones). The angle iron is predrilled to accept the, yet to be made, body on top.
The back story for this loco, it is the result of a local Electrical Engineering firms attempt to build a viable, battery powered (neat uh?) shunting/trip locomotive. They built some 3 foot gauge loco as a test bed for the usual reasons railways built narrow gauge lines. The particular loco in my possession will have been used to demonstrate its usefulness in the military; therefore it will have a camouflaged livery. (Quite how I am going to paint that I don’t know, but YouTube will be my instructor. Every day is a school day with this hobby.)
If I can get a Pantograph for less than an arm and a leg, I would like to stick one of these on the cab roof. Then, of course I can say it is a “Bimode” locomotive. So on trend! (Anyone have a pan they want rid of?) I suppose I could make some sort of “tramesque” collector hoop...
Body wise, I did give some thought to “steampunk”, post apocalyptic gibberish, but decided against it. I can’t see the point of sticking gearwheels on the side for no apparent reason. So I looked then at those NER Electrics. A sort of cut down and bodged version of these would suffice, I think. The rounded nose might be a step too far for my dubious plastic bending skills, though. Or possibly a double ended loco with Hunslet shaped bonnets. These would be nice and simple to make but the bonnets will have to be full width due to the Aluminium plywood braces. Hey ho, I shall see what happens.
Whatever, there will be rivets to count. Last year, for my Birthday, my partner, (gawd bless ‘er) treated me to a Pdf Models Baldwin loco tractor and a very nice model it is too. However, I chickened out of applying the tiny, tiny rivets supplied with it to decorate the bonnet and cabs as I did not want to ruin it. This cobbled together loco will be a test bed for my riveting skills that I will then apply to the tractor...hopefully. I do have a bag of 1/32” rivets and I am flip flopping between these and the stick on ones. Like I said, every day is a school day with this hobby.

Really interesting project, let your imagination run with this. Good start with sturdy chassis and great motor, they are reliable and powerful and used in many of my own locos.
The best things in life are free.... so why am I doing this?

Cheers Peter, I have always liked IPs tin diesels, for all their quirks. And there are a few. There was a chap on 'tube who had mounted a motor in the bonnet, driving a huge gear on the middle axle. I nearly copied him but the bonnet appeared so full of motor, he only had room for a small battery. Which probably leads us on to LiPo or the like. I am a bit apprehensive about these. Anyway, who would have thought my favourite lesson in school was Technical Drawing? It was. So heres three drawings. Bonnets, Cab inside and out. The mists are clearing. I have even sussed out how to make a (non working) pantograph. But thats still in my head.

I’m intrigued by the slaters worm wheel, what reduction is it? I’m not entirely happy with the Deleon chain drive on one of my locos so have been looking at other options, how have you found this setup?

Thanks Old Man Aaron, I have been doing diagrams like this for longer than I can remember :D

Gareth,
Its about 3:1. To clarify, 3 motor: 1 axle.
Things to look out for in my experience:
1) Use Loctite blue glue to assemble wormgear on to motor drive and wormwheel onto axle (via converter bush for 1/8") There are no grubscrews. Sounds a bit poor but works well here.
2) It will not work first time. You will spend a while assembling/dismantling and easing the bores of the gearbox with some fine emery or a needle file. Dont go mad :-)
3) When its working properly, you'll be able to turn the axle and watch the motor shaft turn. The gears seem to be of very good quality. You must line up the motor properly or you will get excessive wear. I just bolt the motor/GB down at the commutator end of the motor and let the drive end float. If its not bolted down tightly the whole thing will align itself.
4) I am not sure if this is right but I packed it with grease. I also put a tiny drop of oil on each bearing surface before I run it.
5) After much messing with, batteries, motor voltages, gearbox ratios the latest iteration is: 14.4v* (12 x half AA) batteries, 12 -24v MFA 30:1 motor gearbox with Graupner 2mm/4mm coupling. I have used this set up for two IP Engineering diesels. It gives a (scale) top speed of about 10mph (90:1 total ratio). The loco I am building out of bits has a set up recovered from one of these, having a 15:1 gearbox(45:1 total ratio).
6)*Please remember that Mtronics sound units upper limit voltage wise is 12. I have the blue smoke experience to verify this.
7) The motor gearboxes are noisy. I am not sure if I am overloading them, (all is well so far) Think of a 1950s bus. if the loco is being pushed by the train then It makes a similar noise to a 1950s bus going downhill. Except, due to its size the pitch is obviously much higher. The backlash of the gears is all it is. It does not bother me.
8) Due to a house move, I am in the process of getting a new railway set up. This is taking some time due to the C*r*n*v*r*s. There will be videos to bore you with!

Hope this helps.
Cheers
John

Many thanks for the info, very helpful! I’ve done two build so far with the mfa 30:1 gearbox motor thing and it seems to the job quite nicely, although both mine are running bevel gear final drive so it’s nice to see another way of doing it, I do like the sound of a 90:1 final ratio!

As my semi retirement slowly morphs into retirement, I found a little time to continue with this. The bonnets are done apart from one or two little bits, filling my hack marks and painting. The cab is just mocked up with Sellotape to see how it looks, it requires a lot more fettling before its good enough. The Jury is out on the addition of windows in the side of the cab, I am 60/40 yes at the moment. Looking through my drawers (oo er missus) I think I can cobble together enough bits for radio control. ahh well we will see! There is still a lot of work to do, but it keeps my brains working, which is good, in these times. If I am not back before Christmas, I would like to wish you all seasons greetings and a happy new year, I do enjoy reading about all your escapades.

That looks really really good and thoroughly impressed with the drawings.

If that is plasticard for the body, how on earth did you get that nice rounded effect on the bonnet?

Hello Steve and Rik, thanks for the comments. I am a bit of a newbie at succeeding with bending Plastikard. I remember my first effort whereby I used a paint stripping heat gun, with predictable results. I should have kept it as some sort of artwork. For these bends however, I borrowed SWMBO and her hair dryer. I marked a pencil line where the bend starts and finishes from the measurements off the drawing. Then using a steel ruler I got SWMBO (bless her!), in oven gloves, to hold down the Plastikard trapped between the ruler and the table. Switching the hairdryer on full, I wafted it over the portion of the plastic to be bent, while cajoling the plastic to bend. You will feel it "go", when it is hot but not melting (!) Dont go mad, just carefully tease the plastic. Stop and turn the it around and start again from the other end of the bend. Finish off by asking SWMBO for further assistance by holding the dryer on maximum and bend the plastic in your hands. Do this by warming the plastic, then placing it in the bowl of your hand and bending it with your fingers. Stating the obvious that you will stand a very good chance of burning yourself if you're not careful. Further to this it is not bent to fit, I bent it to a place that I estimated that the glue would hold it in position. Fingers crossed, it has.
Cheers

Looks just right, that. Those searchlight-type headlamps very much suit the loco. If you're open to suggestions, I daresay if this were a real loco, the side of the cab would have a window or two, for the sake of visibility during shunting.

Blimey. Where does the time go? I relaise now I am not very good at keeping these threads up to date. Anyway, I took some good advice re: the cabside windows, I think it makes it looks wise. Anyway I'm calling it finished. So heres a few phots of Lockdown Locomotive No.1; a battery electric loco that is actually a battery electric. I still need to tweak a few things but it is essentially finished.
