Bash Fodder for GN15 Mechanisms

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Bash Fodder for GN15 Mechanisms

Postby Oztrainz » Thu Dec 06, 2007 11:26 pm

Hi all as per Steve's suggestion on http://forum.gn15.info/viewtopic.php?t=3446 as part of the discusion and to assist all Gnatterboxers,

Here is my contribution of a comparison between the Hornby Bill/Ben chassis and the Smokey Joe chassis. The Smokey Joe chassis is several years old but has a can type motor.

Both locos as bought-

Side by side:

The view from Down Under - note the difference in wheel spacing and the location of the wheels with respect to the rear buffer (only common reference piont as the cylinders and front of Ben comes away when dismantled):

Smokey Joe unwrapped:

I'm sorry but I don't have dimensions such as wheelbase, max height/width for these units readily available, but at least it is a start. When I find where I put them, I will quickly run the verniers over them. and post some dimensions.

Please add pics of other "as bought" and "unwrapped" steam locos here so that we can build up a reference of suitable bash fodder.

Bill looks like it has reduction gearing, so it should run "better", meaning slower!

This was the Bachmann On30 Porter, which is now the power unit of one of my critters.

Guys this sorta info is going to be so needed. I'll keep a very keen eye posted so as to bring myself up to date asap it has been way too long. lLooking forward as to how this er.. um unwraps lol

Ok so here's possibly one for this post... i have noticed that alot of the On30 porter locos available are by default dcc does everyone use dcc now? or are there non dcc On30 drive units available also?

Might I also suggest that someone takes a look at Fleischmann's Black Anna (HO)which I've used in the past to bash for O-16.5. Don't have one at the moment to show. Much better running characterstics than any Hornby and easily obtainable from German eBay.

Well done that man. In view of the above I won't do this now on my web-site in the short term but will post any extras I find here. However the offer still holds good if "boxers" feel that would help.

Certainly something I will find a very useful thread to return to regularly.

I hope these mechanisms are of use. The Lister I threw in just to show I actually can finish a model! Really good at starting em! The Lister rides on the Bachmann Trolley mechanicals. 1. Porter mech by Grandt lines (of course)
2. Scott bs Lister with mild weathering
3. Old Hustler regeared w/NWSL graeset. The flywheels actually came with the original model!
4. The new Grandt chassis minus the gear that flew into oblivion, making it temporarily 2 WD.
Why bother, U may well ask (especially with the poor Photos! Well, all of these chassis (except the Bachmann) can CRAWL up a 6% grade with 2 or 3 weighted cars. I love slow runners (3mph or so)! Ill try to get better with the photos, but my wifes camera doesnt take good closeups (or maybe its me??) Nah!

Michael does the grey surround have to stay on to hold the motor block?

Perhaps instead of just a Steam donors we should have a thread of all different donor mechs with dimensions such as wheel CtoC and wheel size added as we find them with a bit of a critique on run quality, DCC capability(for those interested), and any other info that may be pertinant as a referance.

If you get one of the "Non-Thomas" versions of the Bachmann 0-6-0, then it doesn't have the extra drive bits that do the eyes on Thomas.

No Scott it doesn't but you do need to sort out a way to hold the motor on the US version of Thomas because the motor mechanism is attached to the original top blue part of the body.

In this version I glued the motor to the styrene.

And I appologize for not sticking to the knitting.

Barry I have not seen the version with the red wheels before.

This is the variation on the "Thomas" here in the UK at least, or rather, these are the versions I have :wink:

Steam Mechanisms

Postby Catweasel » Wed Jan 02, 2008 4:47 pm

Fleischmann's Black Anna.I have one of these beasties,and it does run well.However,on undressing it,you are left with a simplified version of the crittur. It's all solid metal! I think I posted some piccies earlier of it.

Hey Jon,
I'm more than happy to rename the thread so that we can have a central repository for the bash fodder that goes under...

I have a Bachmann Percy available, still in bubble pack, i.e. the American Item No:58742 for £21 to UK by recorded delivery.

Is there any chance we can rename this thread 'Motive Power' "Suitable Bash Fodder" or sommit like that and sticky it please. With so many auction sites available and some of the older models being slower and more reliable than some of the motor bogies that are available today, it would serve as a good resource, especially for newcomers to the hobby or the gauge when they can see that you can build a loco/critter/front-end pulling machine/whatever! for not a lot of money.

Hi all,
I have succesfully managed to rename the thread to "Bash Fodder for Gn15 Mechanisms" Given the recent activity in Spuds vs Black Beetles has anyone got some pics of these that can can add here? How about the NWSL PDT as well? These would complement the photos of the Bachmann On30 tram mechanism.

One of the other things that we are missing here is some rough dimensions for each of the unmodified mechanisms such as wheel base, length, widths and height. Anyone got their vernier or ruler handy?

I have no idea as they were purchased in a clear plastic back with no markings. Due to similarity one could be a ripoff of a modified figure from Tamiya 1:24th scale 'Campus Frends' set.

I dismantled the Bachmann trolley/cable car and I can offer some dimensions. These are eyeballed from a ruler, so they won't be accurate to better than 1mm, if that. Refer to Jon's pictures above for more details.

The chassis is really tidy - it's a hefty metal block with a plastic keeper plate on the underneath to retain the axles, and a plastic clamp on top holding the motor in place and carrying the contact wipers. Both are fixed with screws. The intermediate gears ('twixt worm and axle gear) ride on shafts mounted in the chassis block - I assume these could be pushed out but I haven't tried.

The wheelbase is ~41mm (41.5mm?) with 18mm wheel diameter (at the outside of the flange, is that the usual way of measuring?) solid disc wheels. There is rivet detail or something like that around the rims, and they sit slightly recessed into the sides of the metal block. The contact wipers run on the tops of the wheels.

The chassis block is 96mm long by ~24mm wide at the widest part. Most of the chassis is only 18mm wide though. The outer ends aren't necessary but would need sawing off as they are part of the block. If you got rid of them you'd be left with 74mm in length, and you would also lose the screw holes intended for mounting the original body.

Oh yes, and there are little wipers for conducting power to the PCB in the body for the lights. These are attached by little screws through the main pickups into the top clamp plate.

Cheers,

Will
