1863 Thatcher Perkins 4-6-0 Locomotive
Hi All,
I have said all along that I was going to build a diesel as my next locomotive, but the beauty of steam has convinced me to build another steam locomotive.
Having never built an American locomotive - I have decided on the Thatcher Perkins 1863 ten wheeler.
It ran on the Baltimore - Ohio Railway. It was also a troop transport for the Union Army in the American Civil War.
The locomotive was named after the Company's Master of Machinery who designed the locomotive.
Unfortunately - there is not a lot of detailed information on this loco, but hopefullyI will be able to research enough info to do justice to this beautiful locomotive.
I am looking forward to the detail and attempting to replicate the livery of this locomotive.
My build will be 1/8th scale. The overall length of loco and tender combined will be 1900mm
Regards
Keith

Keith, I am getting on board for this build.
The engine looks typical of engines for the period. My guess is it is similar to many Baldwin products with inside motion operating via rockers, outside valves. (Similar to Puffing Billy's Na locomotives.)
Driving position is the right hand side. Front dome is a sand dome. Brakes - what brakes? Hand wheel to apply brakes to wheels on the rear bogie of the tender. Not sure but the middle driver might be flange-less.
Look forward to the build.

Thanks for the links Peter, thanks for the info Kevin.
I was thinking of emailing the museum for a few detailed photos.
I found some blueprint engravings online for the 10 wheelers which will help me a lot. Amazing where you can find some stuff. Been online looking today for at least 3 hours and have some good info.
Interesting about no brakes Kevin - was wondering when brakes were incorporated into the loco and not only on the tender.
1890's ???
Anyway looking up info and history of the loco's I have built is very enjoyable and me get more involved with the build.
Again - thanks for the info guys.
Regards
Keith

Hi All,
Thought I may as well make a start.
I am making my wheels first up. I use the wheels because I know exact sizes and once these are made they are the Standard that I can use for getting all my scales correct.
I first draw up the wheel and then transfer my dimensions to the timber. I an using 19mm pine for my wheels.
As with all my locos I have built - I am doing the wheels in two parts. 1) The outer rim 2) The inner hub and spoke section.
I have also done a photocopy of the loco at the scale I am building. This allows me a reference back to ensure I haven't mucked up any of my scaling.
I cut out the wheel blanks with my bandsaw.
I turn the outer and inner sections of each wheel in my wood lathe, ensuring the lathe faceplate is central by drilling through the timber with a 1mm drill and then marking out the screw hole positions and then fastening the plate to the back of each wheel component.
The photo shows the outer rim of one of the wheels machined.
Regards
Keith

Hi All,
I have been working on the main drive wheels of the locomotive.
I used my jigsaw to cut out the centres of the outer rim and then finished then up using my spindle sander.
The inner spoke / hub section was turned on the woodlathe. Each inner and outer has been numbered as a pair and the inner hub/ spoke section is a sliding fit into the outer rim section.
Next job is to draw up the spokes and incorporate the counterweights into the hub / spoke section.
Regards
Keith

Just a wheel picture i found interesting when building my last train.
Without the paint you can really see how they put it all together.

No point wasting time putting the feet up and having a cuppa, hey Keith?!! Straight back into it.
I think I might skip watching this one however........not, are you kidding. I'll never miss a great build.
looking forward to another great build, yet again.

Hi Keith,
I go away fro three months, and come back to yet another brilliant build ! It promises to be a really nice, nearly two meter project, thanks, I will be following with interest.

Hi All,
It's always slow work on the wheels of my locos.
I have marked up the spokes and counterweights on my internal sections of the wheels.
The Thatcher - Perkins has a radius at the bottom of each spoke. I have drilled these radii with a forstner bit. This gives a much better finish and doesn't rip into the pine.
I have then cut out the segments with my bandsaw and then glued the inner to the outer rim.
At the moment I am carrying out lots of filing and sanding of the spokes. Time consuming - but satisfying.
Regards
Keith

Yes - it's a beautiful machine Bruce. I love the artistry of the colour scheme. It is going to be a joy to build

Hi All,
Lots of filing and sanding. I have got the main drive wheels up to the priming stage. Use Automotive primer in a spray can from Autobarn to prime the majority of my parts.
This locomotive has the counterweight sections of the drive wheels already cast into the wheels. Made it a bit easier - didn't need to cut out the segments between the spokes.
I will make the 4 front bogie wheels and then commence on the chasis.
Regards
Keith

Would have been Trevor's Birthday yesterday and he'd have been so chuffed with you
G'Day Keith, Would have been Trevor's Birthday yesterday and he'd have been so chuffed with you and your magnificent craftsmanship on the loco's ...
You have certainly taken a page from Trevor's book of process details and nailed it in your shed... Well done Keith.
Cheers, Peter
