Chris,

Don't bother with a scriber. The key to making nice straight cuts in plastic sheeting is to make multiple LIGHT passes on the plastic with a sharp #11 blade. Don't try to cut all the way through the plastic on the first (or even third!) pass. For plastic as thick as .040", I'll make no more than 3-4 light passes, and then snap the material apart. I use a metal ruler with double sided tape on the bottom (only changed once in awhile) as a cutting guide.

Working with plastic is a wonderful experience. You can do anything with it you want, and it's very versatile. Yes, it takes a bit of practice, but that's part if the fun!

HI Chris,

Superdetailing plastic steamers, using brass and plastic parts, is actually pretty easy. It takes a LOT less time than working on the old all-metal steam kits, which is one reason I like new plastic steamers so much! I've worked through a few, from simple addition of a few brass parts, to VERY involved reworks that required basically ALL parts scraped off the boiler and re-added!

First of all, you'll need a few tools. Xacto set is a given, along with plenty of sharp #11 blades. A micro file set is helpful, especially when cleaning up brass parts. A pin vise or push drill is needed, along with a selection of micro drill bits. You'll need a good wire cutter, and at least one small pair of pliers. Other than these few tools, you only need liquid plastic cement and superglue, and a jar of Polly Scale Steam Power Black paint. Oh...almost forgot. You'll also need a tube of Squadron green putty, to fill the holes!

Starting with the tender, you have three choices. You can either scratchbuild an oil bunker top out of plastic, buy an oil bunker from Precision Scale, or replace the entire tender with an oil tender from Roundhouse. Scratchbuilding is the cheapest. Just buy some .020" or .030" thick plastic and start cutting. Build the box first, test fit it to the coal space, and glue the sucker in when it looks right. Don't worry about getting the scale exactly right; square corners and the right "look" are generally more important in modeling. Add a oil fill hatch and the wire handholds after the bunker is in place. Buying the P-S oil bunker would be the simplest idea, but I have no idea if the bunker will actually fit into the BLI tender. It's also expensive and hard to get. Using a Roundhouse oil tender (actually a Santa Fe prototype) means you don't have to scratchbuild anything, but you'll have to move the BLI sound unit to the new tender. You MIGHT be able to swap just the tender shells, but I doubt it. Using the Roundhouse tender means you'll have to get an aggressive drill and cut away part of the metal flooring to let the sound out. I's use the BLI tender trucks.

As for the engine, adding new parts is the easy part of the project. First, remove everything that you don't want, and fill the holes with the Squadron putty. You'll have to add putty and sand 2-3 times before you can't see the holes any more, but the time and care is worth it. Next, add all the major brass parts, like the BL feedwater heater. Then cut, shape, and superglue wire to the model, to represent the new piping (the BL system should include a piping diagram). I prefer to drill holes into everything that gets wire, and solder brass to brass, but don't worry about that until your skills improve. Superglue joints are just fine if you take your time and let the glue dry (DON'T use "thick" superglues! They're just normal glue with a filler (talc) that weakent he bond. The strongest superglue is the thin stuff). The new running board is deceptively simple: cut away the part of the old one, and add new boards with strip plastic (either bought or cut from the sheets used for the bunker). Use liquid cement to join the edge of the running board to the boiler, and the drops to the existing boards, and the new part should be plenty strong.

Unfortunately, the only way you'll really learn these skills is by doing them. It's not all that hard, but it can be intimidating at first. If you don't want to "ruin" your BLI engine, practice each step (building a box, shaving off parts, adding new parts & wire, and building running boards) on a cheap Athearn tank car kit!

And feel free to ask any specific questions along the way!


Wow, that's one of the most helpful posts I've read![:D]

Thankfully I already have most of the tools needed, but I'm not very good with styrene modeling (need to get a scriber!!), but as for drilling a hole and gluing in a part I have no problem with (various pipes will need to be taken off/re-routed, and I'll put in a few extra grabs from hand bent brass wire (need to get the special pliers Micro-Mark has for that purpose, not to mention an airbrush!)

I think I'll heed Ray's advice and practice on a Bluebox tank car, It would be a lot cheaper to get that and then know what you're doing on the BLI engine, than to have to order a new body shell from BLI because you ruined the original(I hope I'm not that bad at scratchbuilding, though!)

This is probably going to be a pretty interesting model, so maybe if I have a digital camera by the time I get this project done I'll post pics.

Just one more suggestion to Ray's, for practice, one of the old Monogram/ConCor Hudsons can often be found inexpensively on ebay, and can be detailed into a CB&Q locomotive, like the one in the park in LaCrosse, WI.

BLI heavy 2-8-2 needs to be modified to be CB&Q-prototypical
Posted by Anonymous on Friday, June 4, 2004 8:04 PM
Waiting for my Broadway-Limited USRA Mikado to get here, I rounded up a few pics to help me detail the engine to more of the Q's version of a heavy 2-8-2. Well, I guess I got more than I bargained for.

For CB&Q #5500, I need to do quite a few things to this model:

1. Generator is in wrong place-should be on right side of firebox, just above handrail, not in front of the smoke stack as on stock model.

2."Catwalk" on left side of engine needs a stepped-up part to fit in a Worthington BL heater on left side. Air pump should then go on right side.

3. Stock model has a coal tender. CB&Q's USRA heavies all had oil tenders, so I need to build an oil bunker. Also, end ladder is on the left side of stock model, should be on right side.

4. Railing along the boiler should curve upwards over the smokebox, then around to the other side of the engine, not curving down towards the pilot as on stock model.

These are just the major things, and since beyond this point, if I haven't confused you already, it does get a little confusing, I have some pics so you can see the differences between the actual locomotive and the BLI model.

The first two are pics of Worthington feedwater heater equipped O-4s:

On this you can see the moved air pump and modified handrail on the boiler, as well as the oil tender.You can also see the moved generator on the firebox, just above the handrail if you look closely.


On the bottom one you can see the Worthington heater and modified "catwalk" along the boiler.

Now here's a pic of BLI's model (not production run)

As you can see, for a regular USRA Mike this is fine, but the Q did extensive modifying on these models, and I'll have to do extensive modifying on my model too, if I want it to look closer to the prototype.

The only problem, how do you make some of these add-on parts, especially the modified "catwalk" on the left side, piping to the moved air pump, making the oil bunker on the tender, and the modified handrails? I don't know enough about scratchbuilding to make these parts, so could someone experienced in that field help me? All of the other add-on details I will be OK with adding, but I need some help with doing this project.

Thanks in advance if you can help.
