Putting tires on the Eureka

A short video of putting tires on our 2.5" scale Eureka wheels.

2.5" Scale Baldwin 18-C Eureka on air

This is the 2.5" scale Eureka on air. Still need to do some adjusting.

The transition

After some thinking and some math we started cutting

Transition

Here is the transition peice mocked up on the back boiler section

Transition

Here is another view

Boiler mocked up

Here is the boiler mocked up. Its 36" long, the straight section is 8.625" and the back section is not round but oval shaped. The top half is 8.625" with a straight that is 1.875" long then the lower half is 8.625" again.

Back view

here is the back view of the large boiler section

Facing the boiler shell

Facing the boiler shell and turning the OD down to fit inside the smokebox, eliminating the need to make a ring.

Side Frame

The frame were water jetr cut out of .625" material and are just about 5 feet long. I couldn't get the entire frame in one shot due to its length

Side Frame

Boiler

Almost done. The boiler has 27 .625" copper flues to be rolled in. The backhead, mudring and throttle assembly need to be installed

Boiler

Rear frame

The frame is 100%. The back bumber needs to be finished as well as a few other misc items. All the holes are drilled and tapped.

Front of Frame

Axle box

The axle boxes are roughed machined. Will finish tomorrow

Now we just need to bore the hole for the bushing

Finished Axle box

Just need the oil lite bushings

Finished Axle box

Crosshead Guide Yoke

Fresh from water jet. Need to drill a few holes

Main and connecting rod

fresh from water jet. These rods do not get a hole bored into them for the crank pins and crosshead. The get another part bolted onto the ends "stubs"

Misc Valve rods

Expansion Links

Water jet cut. Just need a little clean up

Expansion link

Misc Pilot truck parts

THe truck frame, pedestals, links, etc

Pilot Deck

This part is heavy! It was cut from .625" plate

Pilot Deck

Pilot truck

The pilot truck frame is finished. Now we just need to finish up the goodies that attach to it as well as the springs.

Driver Casting

These are the wheel castings. No flange, just the hub. We're making tires to shrink on.

Back side of the casting

Test pilot/cow-catcher

We made a test pilot out of wood to ensure we got all the deminsions right. Wood is a lot cheaper than brass if we made a mistake. Having the deminsions correct, we'll make the real pilot out of brass angle.

Test pilot/cow-catcher

Cow catcher

Made from .062" X .312" brass angle (lower bars) and the upper bars (not on yet) are made from .062" X .312" brass angle

Cow catcher

Cow Catcher

Coming together. A few more bars

The only thing left is to make the coupling link and paint.

The Whistle

An exact scaled down size of the original whistle. Almost finshed.

Stack Base 1

Here is one of the lower components for the stack lower stack (base of cinder collector).

Stack Base 2

Heres the a partial assembly of the lower stack (cinder collector)

Lower Stack

Mock up

This is the partially machined stack base, lower stack and a stack template I made to check dimensions.

Mock up

Thhis is the lower stack and stack base withthe stack template. The lower portion of the stack will be press fit into the stack base and also form a portion if the internal stack extension.

Crosshead Pump Bodies

These are going to be the crosshead pump bodies. The larger OD (left side) is going to be milled to a square to accept the intake and discharge chambers.

Crosshead body and Air Chambers

All parts were machiined from 1.500" round brass bar stock

Upper Air Chamber

Turning the drivers

These wheels are just the hubs(rims). We are going to shrink tires on the wheels, just like the prototype.

Driver

The profile is machined and now just needs the axle hole and crank pin hole.

Drivers and Axles

Here are the machined drivers and axles. The drivers still need crank pin holes and tires. The connecting rods await to be profiled.

Drivers and Axles

Equal Beam

This is the equal beam for the driver suspension. This one is the inside beam. The outside has the same profile but has a series of bends to sneak behind the drivers.

Equal Beam

The beam is 19.345" long

Main Crank Pins

These are the main crank pins. The shanks are .750" OD and the major OD is .937"

Rear Crank Pins

Rods&Pins

These are the connecting rods. main rods and main crank pins.

Connecting Rods and Stubs

The Front Stubs are .442" thick 1.25" wide and 2.704" long. The entire rod assembly is over 19" long. Still need to make the half brasses and the back stubs.

Connecting Rods and Stubs

Connecting rods

Here are the connecting rods. One with both front snd rear stubs and front half brass. The bronze bushings still need to be spilt.

Cylinder Pattern

The cylinder pattern is being made by Dave Clark from Ohio. His contact info can be found by clicking on the pattern link on the home page. The pattern is almost done then off to the foundry to be cast.

Cylinder Pattern

Lead Driver

Machined driver and crank pin. The driver still needs the tires. The drivers are 8.00" and the tires will be .750" totaling 8.750" in diameter. The connecting rod still needs the half brasses/bushing for the crank pin.

Rear Driver

Side view

Eureka standing next to the 1.5" scale Kozo 0-4-0. The Eureka dwarfs the 0-4-0. The 0-4-0 is standing on rails and the Eureka is not nor does it have the tires on yet.

Outside equal beam

This the outside equal beam used for the suspension for the drivers. This one sits outside the frame and sneaks behind the drivers.

Outside equal beam

Both equal beams

inside and outside

Both equal beams

Crosshead pump

It'll look like a million bucks once its polished.

Boring the ID for the wheel

Tire shrunk on wheel

Tire on wheel

still cooling down from 700 degrees. You can see a small gap between the wheel and tire.

Tires

After first machining operation. The OD was turned for the flange height and the tires were faced front and back.

Pilot truck chassis

Pilot Truck

Just need to finish the spring retainers and drill holes for cotter pins and its finshed besides paint.

Pilot Truck

Springs and Stirrups

This shows the equalizing bar and the spring stirrups. The bottom springs have a keeper spot welded to them to retain the springs in the stirrups. The springs are .062"x.500" and there are 10 of them.

Springs and Stirrups

Cylinder Castings

Cab Bracket Pattern

Pattern made by DAVE CLARK

Cylinder and cab brackets

Finally, the second cylinder and cab brackets were cast.

Cylinder mocked up

We have one good cylinder and still waiting on a second. The original foundry poured two, but only one came out right. The second, had the porting wrong. We switched foundries and are currently waiting on the second cylinder.

Cylinder mocked up

New cylinder

You can see the difference in the two cylinders. The one on the left came from the foundry we are currently using. Although it would work, the appearance is drastically different. The foundry is pouring a replacement cylinder for us to match the existing cylinder.

Rod bearing halves

The rod stubs and bearings are made up of indivdiual parts as was the protype. These are not a one part rod like most rod castings. Our rods have a total of 10 parts to make up one rod.
