Dennis’s 763 ( 6-18056 ) Hudson gets the swap! Tales From Harmon Shops

Wow, look at that snazzy driveline!

I think I'd run it with the shell off so it can be appreciated!

And here’s the result of doing good clean, solid work,…….notice how balanced these shafts remain at rpm …..she’s rock solid and super smooth!….

Pat

That is nice.

That's pretty cool!!

GOOD LORD!    GOD ALMIGHTY!  SWEET!  Thanks Pat!   I'll pull out my Old, NIB, Never Been Run NYC Pullman 20th Century's and oil them up!

Pat, that sure does run smooth.  Do you machine the up flywheels to go on the Pittman ?

That driveshaft looks slick with a slip joint no less. Is this a train part or is it from an RC car ?

Dave, I use an off the shelf flywheel, that’s actually made for a Mabuchi motor, bore it, and counter bore it for set screws,…..the driveshafts are indeed RC car parts,…they’re available in a dizzying array of lengths, and luckily already are set up for common 4mm shafts,…..the shafts are steel, not pot metal, are very well constructed, and pretty precise,…the universals are very smooth and are made of steel as well,….end result, it will out last all of us straight to the landfill,….😉

Pat

Another beauty Pat.

Looks great, Pat!!!!

Thanks Rick, I think this’ll be a wee bit more robust than …….dare I say it??…..a Legacy gear box?..

Pat

Wow, Dennis's is in the Harmon Shops, a great preview of all those other engines to come. Can't wait to see how Dennis's turns out. Awesome work as usual Pat.

Builder’s Photos!!…..Dennis’s 763 ready to emerge from the shops for revenue duty,….

upgreades include: ERR cruise, fan smoke, John’s chuff stuff (TM), real headlight reflector & lens. detailed cab interior, much better looking pilot truck, and of course, a big fat Pittman….video coming, stay tuned!…

Pat

Making her way to the ready tracks,….fresh from being shopped….

Pat

It's beautiful, sounds great, and runs so smooth!  A fine job, Pat!  Dennis will love it!

Looks and sounds great.  Now the tender needs the shorter drawbar.  Just installed one on my Centipede tender.

Hi Pat,

That's now a fine piece of artwork!!!!!

Alex

Superbly done, Pat.  (And that new pilot truck really is a huge visual improvement.)

Pat:

    Very sm-o-o-o-th! Beautiful work!

John

Puts my old 763E to same

Thank you fellas, ….I must admit, the pilot truck inspiration comes from Ron H.’s recent thread on his Williams Masterpiece Hudson,….Ron used a 2 rail pilot truck with add on details to make a fine looking model,…..so for Dennis’s Hudson, I used the stock Lionel truck frame, and some 2 rail scale pilot wheels….but what I did was to chuck up the 2 rail wheels and turn down the tires to increase the flange height so they’d track well through 3 rail track, be it tube track, fastrack, or I rail ….that was worth the effort,……I removed .015 from the tire’s diameter and gained a lot more flange for 3 rail operations…..the pilot truck navigates Atlas no. 5’s with out issues, …and y’all know those are some of the worst offenders in the business….😉

Pat

Tender change? Is there a big lever next to the engineer or is that a trick or the light? I didn't see if there was a wire tether or not, hard as heck to see. Very curious though Pat, very curious indeed. Nice crew as well.

I know someone had mentioned on one of the earlier Hudson discussions about changing out the drivers on certain model Hudson when discs weren't supposed to be in that particular model, I think that was on one of the J3's though, right Pat, not the J1?

I love the driveline, getting rid of the dogbone must really smooth things out.

Awesome Pat!   Are you clairvoyant?    I don't recall discussing Atlas no. 5s... which, I have!

Pat... you are ...the MAN!  Thank You!

I especially like the piston valve motion. It's a good thing!!!

Pat: Amazing work! Such a thrill to see what can be done by the great train wizards on this forum!

Ron, I hope you don’t mind, I drew inspiration for the front pilot truck from your work,….I think this needs to be a SOP when doing these Hudson conversions……although I cheated a little to gain some flange height for whatever 3 rail track scenarios could be tossed at it,…your work is top shelf, and I only imitate your artistry ….😉

That’s just a loaner tender from my buddy Chris’s Hudson…..Dennis has his PT tender home with him,….he’s a smart mechanic himself, I’m sure he can swap his draw bar out,…..anybody that can mess with ancient Mercedes Benz engines surely can swap a tender draw bar,…..they’d get my vote …..

my good and ooberly patient buddy Chris’s Super Hudson is on deck next,…

You’ll be witnessing this driveline very soon sir, ….that set up is now standard procedure for Pulmor conversions…..smooth isn’t the word,….speed step 1 is super smooth, with no stalls….

Pat

Nice work, as per usual. I don't expect anything less.

That clearly beats the pants off the old dogbone, that looks like something I might consider for some stuff that already has a can motor.

I think I'll have to watch the video on my laptop when I get home to see it better. It's very tiny on the phone, lol.

FYI Dennis, et al., The drawbars from the scale 0-8-0 tenders are a perfect fit if you can still get them. Alternatively just cut and overlap the two pieces and solder together after removing the blueing. They are only .050” thick and have no effect on the optos lining up.
Another fine engine from the Master.👍

Pete

Super slick work, Pat!

Can't wait to see mine getting a similar treatment. The difference performance before and after is like night and day!

Yep, …the thing is, these Pulmor equipped steam locomotives respond to a Pittman swap like nobody’s business,….the gearing is just right on the money,….so when the motor begins to spin, they’re already in the sweet spot for making power,…..good stuff!!

How many 18056's are in the shops Pat? With Dennis's, Thomas's and mine, that's 3. Maybe just J1a's which I know is about 5 or so.

I’ve got about half dozen J1e’s from various mfr.’s to build,….all are under way, …it’ll get way better when they take my day job away from me……☺️

Pat

Pat another superb job.  Not even a hint of a wobble on that shaft.

Pat, do you know the answer to the disc driver question I asked here?
