Davenport Rollout

Those of you who saw the photo contest results on Durango Dan's One Twenty Point Me site have seen the first public appearance of Slate Creek Railway #2, the 10 Ton Davenport we've been talking about here since November. I particularly liked the engine that won second place, as I've been considering building something similar for some time now, but I was both pleased and surprised to discover I'd placed in the contest as well.

It's been quite a ride, as you can see in all of the previous posts, from delivery, to teardown, to sandwiching all that gear under the hood, to trying to get everything to function, this little engine has turned into a BIG project. But, even with the external detail changes being somewhat small, the difference is noteworthy, I think:

Before

After

While I still have some more weathering to do, and an antenna issue to work on, this is pretty much what the locomotive will look like from now on. For such a small locomotive, the hours it took to change everything were more than I ever would have guessed... here's a list of "projects" that went into this tiny unit:

a.) Removed factory electronics, and installed RCS radio control, Phoenix P5 sound, P5T interface, and 12 Ni-CD batteries under the hood, the radio under the rear frame, the speaker under the front frame, and the charge jack in the rear wall of the cab.

b.) Removed the Bachmann supplied seat, raised the control stand, and reworked its controls. Added a gear shift lever, clutch, and a new "fold down" style seat in the cab, as well as a pull and valve for the air horns. Also built and added a "sand box" on the fireman's side to match up with the sand fill cover made to cover up the charging jack in the back wall of the cab.

c.) Added the sand fill cover, air horns, and bell, and bell rope. Added the headlight in the rear wall of the cab, and wiring. Also removed the factory stack, and built a replacement one, and replaced the front headlight with a smaller one that looked more the right size for a loco this size. (The one that comes on it is the same as the electric headlight on the 2-8-0!) And, I rebuilt the front end of the locomotive, covering the radiator with HO scale aluminum siding so that the radiator fins would all be horizontal, and removed the handrail supports from the radiator. I made a new grill from brass angle and rod, and added bolts, and a screen to finish it up (the screen was actually some kind of brass decking in HO scale, I think, but it was available in sheets from the LHS!) Oh, and I'm particularly proud of the smokestack; after drawing out what I wanted to do with the front end several times, I was having trouble finding something that "looked right." I looked at toys and truck models, and nothing looked quite right... then I looked at the pen I was drawing with, and realized, if I cut it down, and pulled out the rubber grip....



d.) Finally a set of Slate Creek decals, and some weather treatment to take off the "shine" ... though I'm planning to do more in the weather department in the future.

I'm very pleased with how it came out, particularly since it's my first total conversion/bash/detail project. It will be interesting to see what's next!

I'll sign off with a couple of other photos...

We're Still Here!

It's been awhile!

Somewhere between the holidays and everything else that was going on since my last post, things on the railroad and in the shop have fallen seriously behind, but that's all changing rapidly.

Stay tuned for the "finished" posts on the Davenport (really, I mean it!) Just a little more tweaking and testing, and I'll be ready for a "rolling out!"

I've got to. Something BIG is headed for the Slate Creek shops, and it'll take up the whole shop once it arrives ... I have to make room!

Hopefully this will be a bit more exciting place to visit in the coming months!

Almost There

Yes, I know. Christmas is coming too ...

My "To Do" list on the Davenport (post electrical/mechanical) is down from about 25 items to about a dozen:

Build/Install front and rear headlight lenses
Build sandbox covers.
Install horn and bell pull cords.
Clean and reinstall cab on locomotive
Install radio on locomotive, connect antenna.
Install bell on hood and horns on roof.
Connect front, rear headlights.
Build muffler, remove old smokestack, install new muffler on hood.
Install hood.
Modify radiator & Build grill guard, reinstall
Build and install flag holders, or match paint and cover old hood slots.
Add decals, other graphics, and Marcus.
Test.

And, I think I may see what I can find in the large diecast toy section of Tractor Supply to save me building a muffler... some of theirs are quite detailed, and should work nicely in 1:20.3 for a smaller stack.

I had hoped this post would wave the "FINISHED" banner ... but I'm spending my day dealing with a main drain clog (again,) and may therefore end up delayed for a few days!

Vital Signs

As of today, the major electrical work on the Davenport is finished.

This tiny locomotive now sports 12 NiCd batteries, an ELITE throttle by RCS, and a Phoenix P5 sound system, as well as a P5T interface board, and all of the requisite wiring to make them all work, under the tiny hood.

The power switch is under the rear frame of the locomotive, as is the radio receiver. The small speaker will fit in front, between the frames. The charging jack will go in the rear cab wall, and be disguised by a sand box / cab seat on the inside, and either a sand fill or a handbrake on the outside. I'll go more into the cosmetic details next time, when I have photos to show how they're progressing... the big news TODAY is that other than connecting the headlights, the electrical work on this locomotive is FINISHED!

The first trial fitting of the various components was not especially encouraging (and, I'm told led to indigestion in some quarters!) There seemed to be no way to fit everything in ... and more wire than a local telephone exchange!



I found the best way to overcome the "octopus" the project seemed to be swallowed by was to remove all of the extra wires from the Phoenix and P5T ... there are several extra wires pinned into the plugs that aren't needed for what I'm doing here. I also shortened up harnesses where possible, and then connected what was left in neat, organized bundles. With the battery pack modified from its standard 4-4-4 arrangement to a top row of 4, a middle row of 5, and a bottom row of 3 cells, I found I had room for all of the electronics on top (including the Phoenix P5 at the extreme rear of the hood, vertically,) and sufficient clearance for the worm and gears underneath. With the battery secured to the right hand side of the hood, there was a space along the left that accomodated the P5T, and all of the bundled wires, as well as the volume switch. With the "Octopus" gone, everything finally fit in a functional, if crowded, way.



Much better! The programming port can be removed by unplugging it from the board once the board has been programmed ... which I did (though not before taking the photo above, apparently.) All that was left was a full scale test ... and I'm happy to report everything started up and ran like a charm... both sound and motor. The speaker in the above photo is a full size Phoenix speaker, and I used it just for testing -- the actual speaker is much smaller and will fit between the front frames, and ahead of the power block.

Now to finish up, there's still lots of cosmetic work to do, as well as final re-assembly, and cleaning up all the debris and marks that a major surgery like this always leaves ...

But today, it's alive! ALLLIIIIVE!

Getting There (Much like the Tortoise...)

No photos yet... but for folks looking for progress, there is progress!

The electronics are almost finished. The locomotive now has an RCS ELITE throttle, Phoenix P5 sound card, a P5T interface, radio receiver, charging jack and power switch all installed. I'm waiting for a speaker for the Phoenix to be delivered. The hood and the lid are both on the frame, and taped in place while the RTV that holds the battery pack in place sets up; this is somewhat delicate, as everything fits, but only just. The new headlight and horns are ready to go, the rear headlight has been fabricated, and once I have some styrene and brass in hand (and some JB Weld!) I'll be able to finish things up. Oh, and I'll need to charge the battery ...

Stay tuned. I expect more, and photos soon.

Fully Apart

In an effort to keep this series in order, today's update shows the fully stripped down frame of the Davenport.

You can see the cavity in which the motor mounts; there are two "D" shaped brackets on the motor that allow it to be screwed into the bottom of the large metal "hump" that takes up the center of the cab area. Removing the one at the non shaft end allows the motor to come completely out. And, any earlier questions about the frame are answered; the black and gray areas are all one piece and the "hump" is an integral part. The whole frame is metal, by the way, which makes gluing and drilling a little different from what you might be used to on a plastic locomotive! Here also you can see the bottom end of the power truck, consisting of the gearbox and axles. It's held to the bottom of the deck by four standoffs that are cast into the floor, and when removed has a strange strong resemblance to an HO power truck (only much larger.) Now, the trick will be to get all of the various components arranged and mounted, and the wires between them run, and organized. It looks like the power switch and radio receiver will go under the cab between the frame rails, and the speaker will go up front under the frame just below the factory supplied speaker grille (which has beene removed.) Everything else has fit under the hood, and the standard rear charging / aux power jack will be concealed on the fireman's side of the cab, and will resemble a sand fill and sand box with a seat on top. I plan to redo the engineer's side of the cab somewhat, as I'm not thrilled with the size or position of the factory control surfaces. We even have an engineer enroute from Hawaii to take charge of things once the unit is operational (thanks Richard!) although I suspect he may have to be temporarily assigned to K-27 duty ... and it may be hard to get him to step down to the little 10 tonner after that!

Stay tuned ... there's more coming!

Crossing the Rubicon

After lengthy discussion with Dave Goodson, I've decided that Slate Creek #2 will be converted to Battery Power and Radio Control (by RCS) here in the Slate Creek shops. Dave will be chief technical advisor, and will hopefully prevent me from blowing anything up along the way!

Here's what the Davenport looks like with the top off the hood, and the Bachmann circuit board removed. There are three plugs on the circuit board; one for the headlight, one for the power IN from the track, and one for the power OUT to the motor. Removing these, and four screws, and we can see what's underneath.

The large silver object is actually a stack of eleven metal plates that are notched to allow space for the worm gear and the gear it drives on the gearbox, which is attached from underneath as part of the truck. The front of the plates have a roundish bite taken out of them, which corresponds with the round speaker mounting underneath; you could put a small speaker here, and half of it would have a grille to the outside, underneath the engine, between the frames.

Removing the weights we can finally see all the way to the bottom of the hood space. Note the gear oil all over the place, and the channels that the motor wires pass through to get to the motor. This gives you an idea of the space we're going to have to work with to install batteries, radio receiver, throttle, and sound equipment. Needless to say, some creativity is on the horizon ....

To properly arrange everything, though, the rest of the locomotive needs to come apart, so we can see what space there is to work with, and what other obstacles may present themselves. The cab is held on by two screws at the front, and an odd arrangement of two screws that hold tabs in place that mate with locking tabs on the back of the cab... removing the screws, one can remove the plastic "pins" and the locking tabs can slide upward. There are four screws that hold the hood in place. That leaves us with the bare frame of the locomotive. Now you can see the "grey area" that appears as the cab floor and the surrounding black painted area that makes up the rest of the deck. While the sides of the "frame" are screwed on from underneath, the deck itself is a single massive cast piece that includes the "grey area" and the large domed "hump" that would presumably represent a huge transmission on a gas-mechanical loco like this one. The motor is actually accessed from underneath; removing the power truck (from the primary gears down, it comes away in one piece) exposes the plate through which one has access to the two brackets that hold the motor in place. (I haven't removed the truck yet, so while you can see the motor access "hatch" you'll have to wait for the next installment to see inside!)

So the plan is, now, to tackle the following laundry list:

1.) The battery/radio control/sound gear is in transit... when it arrives I will need to find a way to fit it all inside the locomotive.

2.) My new headlights have arrived, and are much more like what I had in mind for this locomotive. I will add the headlight, modify the hood to accomodate them, install one in the rear cab wall, modify and install the horns and locate a bell, and decal the locomotive all while it's apart. Oh, and I plan to move the grabiron standoffs from their unusual placement on the radiator to either side of the radiator as they should be ... and I may make a grille guard for the radiator itself.

3.) The seat in the cab bugs me. It appears to be too small for most of the 1:20 people I've met, though that tiny Sherman Pippin found in some of the earlier Bachmann locos might be comfortable. So, I'm going to rework the controls and seat along the lines of a "Big-n-Tall" accomodation ... anyone who thinks I may have a personal stake in that approach ... I have no comment at all as to whether I'm thinking of a 1:20.myself in that cab when I think this way!

4.) At that point it'll be time to reassemble and test. Stay tuned for that, and everything in between!
