Re: Adventures in the land of fully sprung diesels

Thanks for your kind comments Horsetan. The bolster arrangement is indeed inspired by Chris Pendleton's work on his Deltic merely reversed so the flanges are on the bogie. MRJ 188 has been well thumbed over the past couple of years! Work continues, mainly on the Class 37 which has become D6904. Afte...

Re: Screw couplings

Hi Chris,

Masokits do some nice etched screw couplings. They're fairly straightforward to assemble. I've used then on a number of wagons and I think they look pretty good. They are certainly a lot finer than many others that I've come across.

Re: Sprung Class 47 Bogies

Thanks Jon. I've seen some of your work and that's also pretty inspirational. Nimbus is beautiful. I've seen your Blog on the Class 47. I'm waiting to see how you get on before ploughing on with mine :), particularly with regard to the body. Hopefully I'll get chance to make a start on detailing the...

Re: Sprung Class 47 Bogies

Now that I have a pair of bogies made up it's time to get them fitted to the loco along with their drivetrains . The first thing to do was cut the Bachmann drivetrains nearly in half and tidy them up. I doubt that I will ever have the space to run full length trains so I'm just going to use two powe...

Re: LMS Axlebox/spring casting, J hanger type

Hi John, Comet models do an LMS axlebox spring/J hanger casting ref. C17. They use it in their Stove R kit. I've just dug out my Connoisseur LMS brake van kits and the Comet casting looks the same type to me, though I am no expert. Having looked at the W-Iron castings in the kit it shouldn't be too ...

Re: Bachman 3F tender loco.

Mousa Models (Bill Bedford) list an etched chassis for a 3F. I have no idea how compatible it would be with the Bachmann model, it was designed to fit the old MPD kit. Might be worth a look though.

Re: Sprung Class 47 Bogies

Hi all, Thank you all for your kind words. I don't think I've mentioned it on here but Terry Bendall has invited me along to this years Scaleforum to do a demonstration on sprung diesel bogies as part of modelling the diesel and electric era. All my sprung diesels will be there and hopefully I'll ha...

Re: Sprung Class 47 Bogies

Time to sort out the suspension for these bogies. Primary springs are 0.011" guitar wire simply soldered to the spring supports that were soldered and riveted to the sideframes. It was a bit of a pain to get the wire aligned properly as the spring bearers on top of the hornblocks are mostly onl...

Re: Sprung Class 47 Bogies

Inbetween work on other things more progress has been made. Now that the sideframes are ready they can be formed into bogies. Alan Gibson P4 frame spacers were soldered to one corner of each sideframe and 5mm below the top of the sideframe. This was done with the aid of a strip of 5mm thick hardwood...

Re: Adventures in the land of fully sprung diesels

Hi Richard, The method of attachment varies depending on what the model had. I've tried to make use of whatever of the original I can to make life easy. The following is the Bachmann Warship. I took the locating lugs off the sides of metal chassis block to save grinding it out as per Mr Norgrove and...

Re: Sprung Class 47 Bogies

Next job is to sort out the primary suspension foundations while things are easily accessible. The foundations consist of 3 (2.95 actual) x 1.5mm brass L section onto which the springs will be soldered. They need to be arranged so that the distance from the edge to the spring bearer on the hornblock...

Re: Sprung Class 47 Bogies

Interesting how much these etches would actually cost John. I guess it comes down to personal preference as to what cost effective actually is situations like this and whether it's quicker for a pair or two of bogies to get the skrawker and piercing saw out or sort out etches. Etches would make thin...

Re: Sprung Class 47 Bogies

Hi all, Thanks Craig. Whenever you get time will be fantastic. Hope the new job's going well. Your drawing John looks pretty spot on. I should get around to learning CAD as it would make things a bit easier with things like this. My concern lies not in the difficulty but in my propensity to go a bit...

Sprung Class 47 Bogies

Having had a nose through this section of the forum I've noticed that in the matter of chassis and suspensions it all seems to be about steam locos. Nothing really wrong with that but I thought I'd do my bit to redress the balance a little in the direction of the diesel and electrics! :) The latest ...

Re: Adventures in the land of fully sprung diesels

I've done some more work to the class 37 and have recently taken the underframe to pieces in order to paint it. I took the opertunity to get a pic of the bogies without the wheels and geartrain which hopefully will better illustrate the layout of the springs. Finished Bogies.JPG I manage to keep fin...

Re: Adventures in the land of fully sprung diesels

Hi Craig, Don't worry. That's a very nice collection of working timetables you've managed to gather some of which would indeed be really useful. My very embryonic layout will be set somewhere in the period 1963/65 and is based on a fictional secondary line to the north of Cardiff running between jus...

Re: Adventures in the land of fully sprung diesels

I haven't had any issues with the meshing on the gears on the class 37. I think the arrangement of the gears is pretty much the same as the AWD ones except that of course that only the two axle are powered. I've had a look at my Bachmann class 47 that will get the treatment at some point and the arr...
