I've decided that Bitzabash #3, a tank loco, needs to be converted,
to something like an SPNG loco #9 for the Comstock and Southern livery.

The #3 is 'cute', but too much like so many other commercial offerings.

It will have a smaller cab, shed the saddle tank, and have a whaleback tender.
The effort will tune a bit better to 1:24, a 2-4-0 is the intention.

2-1/2" PVC pipe has a 2.85" outside diameter,
I have some 1/8" styrene for the straight bit on the sides.

I have a mystery origin tender that is 3.25" wide,
and some PVC that will look good as a boiler.

Time for some plastic surgery.
Stay tuned for build details.

Wes,

Do you have a photo of the engine you'd like make from this,

or will it be a freelance?

Regards, Dave L.

The SPNG #18 is the inspiration,

although mine will be a freelance version 0-4-0 or 2-4-0 or 2-4-2,

depending on my luck/skill with the trailing and lead trucks.

Starting with the tender.

Donor tender chassis was from a 1999 Bachmann Columbia 2-4-2,
widely regarded as a Basenji dog (woofless) of a locomotive,
so no regrets in sacrificing bits for the build.

2-1/2" PVC is rare.
Home Depot and Lowes do not stock ANY.
So I used 2" couplers and these came out to be the right diameter.

Making straight cuts to half these is no mean feat.
They have to be exact, and flat on the edge that mates with the riser.
I hand sawed the PVC couplers until I realized I could safely use the band saw.

Years ago my parents had a Basenji. 
That dog could sail over a six foot high wall!

For those that do not have a band saw,
any suggestions on how to cut PVC pipe lengthwise ?

You can use a drill press or a Dremel with stand.

Draw a center line on both sides and then cut with a cutting disk.

I cut the PVC couplers in half,
by applying, first, a little geometry to find the half mark.

I used a caliper, but any two parallel surfaces will do.
Where the parallels touche the circle, that's your marks.

Now use the mark and a little machinist's square,
to draw your lines in pencil at a right angle to the end of the coupler.

For the actual cut, I used a Zona saw for the first two.
You could also place the coupler in a vise,
and use a 32TPI hack saw blade to make the cuts.

Sand the halves to make sure the bottoms are flat,
so they will bond nicely to the top edge of the 'riser'
(I settled on a 1" riser, mostly driven by aesthetics).

Americanized steam chests
Banded boiler
Shaped domes
Fitted cab

Can't decide on pilot: industrial or cow-catcher

Nice work Wes. 

I vote for the industrial front.
