Large Scale Central

Rick's MIK 25

Well it is finally time again, I have cleared the benches and am ready to go.
So here is my idea.

When I saw this posted by Peter in the “Strange Locomotives” thread I saved the pictures and looked for others knowing I just had to build one someday. Then up popped Dave with this years subject, perfect.
But it does remain to be seen if I can finish it in time.

Here it is in all it’s beauty, I was able to locate a second picture but not much else.

After checking through the junk, errr, I mean supplies I came up with a new unused 10 wheeler chassis and a few other pieces but there is a lot of scratch building to do. The chassis does not have the correct driver spacing but oh well it will have to do. I can change the pilot wheel spacing without much work.

This is one of the newer ones but still plastic gears instead of metal.

Enough lead sheet to use for weight, within 1 oz of the factory weight.

My blueprint for building a Cat 60 engine to power the beast. I thought I might be able to buy an engine model and I can, seems they start at about 50 bucks and go to 350 bucks so scratch building is looking pretty good.

OK, the mandatory shop towel drawing.

Looks to be shaping up as another great Challenge year with the number of entries so far.
Let’s have fun.

Wow that is a crazy rig! What did they use it for? I don’t see a coupler or draw bar?

Knowing your scratch building ability this will be a very fun project to see come together.

Looking forward to this one, Rick. I can see a lot of new (for me) modeling skills that I can learn watching this one come together.

Tod, I have no idea where it was used or for what. The pictures look to be desert country so maybe some kind of mining/mineral transport.

I, however will be using it as woods crew transport on my logging operations. Using an existing trail car with battery, sound, RC. Just have to build a new shell for the trail car.

OK, day one is off to a good start.

I removed the valve gear and connecting rods by cutting the cylinders and valve chests free from the cross member. I intended to reuse the cross member and it made it far easier to remove the valve gear.

Found the axel tubing typically split on the pilot wheel axels, glue or replace a decision for later.

I cut a 1/2 inch out of the pilot truck on each side of center to make it look more like the prototype.

All cut and ready to glue up.

I used .060 by .250 Styrene strip to frame the truck back together to keep the assembly straight and square. When it dried enough I added a piece of 3/16ths rod embedded in Epoxy for strength and a little extra weight.

A normal pilot truck sitting in front of our modified one to highlight the difference it made in the looks.

Chopped off the nose getting ready to rebuild the whole front pilot beam area.

More fun tomorrow afternoon.

Reading through the forum just a bit ago looks like MIK is going to be great again this year.

Rick, I enjoy watching you modify existing stock with surgical precision.

When did you acquire an mini table saw? I don’t recall ever seeing evidence of that in your photos before.

Looking good so far. Like the way you did the pilot truck mod especially the epoxy rod. Good idea for all the reasons you mentioned

KId-zilla was a bit amazed you cut up a 4-6-0 chassis! He has plans for another 10-wheeler this summer, himself!

Thanks for the input guys.
Craig, I have had that Micro Mark saw for several years, I guess it just never came up in conversation before. Not terribly accurate but if your careful it can get the job done.

As for Kid-zilla, the way he is going it won’t be long before he is chopping up locomotives as well.

Day 2’s update, not much got done.

I did get the bottom boiler sides cut loose from the superstructure and some of the screw posts cut out.

Added some bracing and stiffeners for the pilot truck area and decided to add a headlight to the pilot truck. The headlight and mount were donated by a scrapped Shay.

Turned down a piece of PVC pipe to make the clutch housing for the back of the engine.

Got a start on the engine block and clutch assembly.

Maybe more fun tomorrow.

You are setting a pretty high bar, as usual. Nice work.

And that’s different than any other time??

Always brilliant eye for scratch built detail

I was wondering what that was.

That should have read epoxy AND rod

Been pretty tied up with other things the last two days but got a little time this afternoon to work on the project.

I sorted out the wiring and it’s routing and realized I hadn’t thought about a speaker so back to the scrap boxes and found a small one that will have to do.

Got the engine mounts figured out, the oil pan installed on the engine block and started on the front pilot beam.

Also discovered that the loop on the back of the engine chassis that the tender bar drops into is the perfect height to mount the KD draft box on and line up with the coupler gauge, no chopping necessary.

The rest of the week looks free of distractions so hoping for substantial progress.

Dude you’re amazing. A wood and plastic scratch built transmission. Awesome work. Already coming to meet my expectations

Well I got the front and rear pilot beams done and the coupler mounted.
Boy, these little fiddely bits take the time to complete.

Hopefully tomorrow we will get the headlight mounted and get going on the main deck.

The rear beam with coupler and lift bar.

The front beam, hopefully it will look a little less awkward after the headlight and radiator are installed to fill up some of that empty space.

AS always looking great. And such a unique build .

Today’s update.
Can’t believe that tomorrow will be one week already gone.

Spent a lot of time today grinding out mounting post’s etc. in the chassis so I could install sheet lead for weight,

Installed about half of the needed weight in and on the chassis, the rest will go in the tank and under the top deck.

The front and rear engine mounts are done and mounted with centering pins for quick in and out mounting making painting and finishing easier.

The headlight is installed and ready for wiring. For some reason it wanted to tilt upward forcing the use of a shim to make it appear level.

Hopefully will get started on the main deck tomorrow.
Thanks for taking a look.
Rick
