You can see the process of development 100 years after, just not then. Like why do they need a front steering wheel? Obviously not but back then? I grew up in a farm in the 1970’s with big tractors but the difference to farmers by was very very different 

[RGL]

Coming togeather but you can see from the size or the gaps on this fuel tank, this is the fight I’m having with the poor molds 

[Canute]

Tine to break out your favorite filler. Are these styrene or resin?

[Egilman]

A kinda soft styrene they have been using recently... I have the same thing here, not only is the mating edge uneven it is rounded instead of having a sharp corner....

 

To a modeler it is a minor issue, we know how to fix it, but it  becomes a frustration when they fail to handle the basics of good mold making....

 

I hear ya Greg....

[CDW]

Poor molds or not, they are looking very good from where I'm sitting. Carry on.

Maybe there were no steering clutches on the track drives? 

[Egilman]

1903 Technology, clutched and braked differential steering for tracked units hadn't been adopted when Holt was designing their tractors.....

If you take a quick trip into the history of Holt tractors, the first machines that Holt  built were all wheeled tractors. The tracks were a later development driven by the need to spread the tractor’s weight out over a greater surface area when working soft ground. The other option was to use massively large diameter and width drive wheels, which would have been impractical. So as a development of a four wheeled machine, a steering clutch was unnecessary.
 

Holt did eventually buy the patent for a steering clutch system (from Richard Hornsby & Sons), in 1912. This did enable Holt to eventually do away with the front tiller wheel, but likely any manufacturing development would not have come early enough for government requirements driven by WW1.

Yep, and eventually Holt became the Caterpillar Corporation.... And, in 1914, they were the first to provide the military with a steerable tracked tractor, the two and a half, five and ten ton artillery tractors.... The five ton was especially useful pulling everything up to 155mm... This greatly eased the pressure on the Holts which then were used exclusively for the heavy artillery and vehicle recovery....

 

Commander models does the five ton in resin....

We are cannon fodder.

I really like a lot of the subjects that Rosen produce and I have build some of their 1/72 kits. Some detail is excellent but in other areas flash is horrible and swamps the part

The engine, lots of pieces and lots of clean up needed. Full day to clean up and add to the engine block, lots of blobs cut out to help with alignment and tomorrow I can add sone details. The beauty of this engine is that it’s simple but lot and lots of reference photos 

[RGL]

So we are all probably old enough to remember the horrible soft plastic from Airfix, and according it’s bloody hard to work with. I’ve cut and sanded for hours so I could improve on the cylinder heads to look a little better. I’ll do the wiring once I’ve painted it.

Yes 😉

Nice work on these engines.

[Toolmaker]

I’m appreciating your attention to detail, the kit looks very good, but your additions will make all the difference. The only thing I can think to add is you might have looked at thinning the fan blades. When I built a universal carrier the manufacturer had added etch for that particular item to offer better scale reproduction;

 

Thank you

Good point but it will be inside a cowling so not really worth th effort.

Oh yes, the stuff that seemed to push your blades around to everywhere you didn't want to cut.....

 

They look mighty nice in their civilian colors, (green & black with red letters) shame it has to be a military paint job....

 

What are you going to use for wire? there's only room for one wire bundle, between the wire loom tube and the magneto, the actual spark plug connection is molded in the plastic.... (that tube running down the right side of the engine that curls up to the heads)

Ha, now why didn’t I think of that 👍🏼

Wire?

OK, My allotment of stupid question for the day... {chuckle}

 

What type of wire is what I probably should have asked...

[RGL]

I’ve got some very thin stuff used for 1/350 railings

Pictures are great, but you just can’t beat hearing those old engines run:

[mtaylor]

Wonderful engines.   Love the video.  I do believe that today if a company tried to bring one to commercial market it would never happen.  The lawyers would want tons of protective covers every where.

[RGL]

It’s got amputation Written all over it. 

[RGL]

So today I cut off all the remaining pieces off the Sprue and cleaned them up. 
 

every online build says the roof section has sink marks all down the centre. For once had a win and I had none whatsoever but I noticed Rock Lawler on his Propaganda site had put a strip down the middle to cover it. Made perfect sense so I did it as well and riveted mine in 

[RGL]

Next I’ve put off till last as I’m dreading it. At least they are only clipped togeather with no glue 

[Canute]

The only break is your sprue attach points are on the sides, away from the linkages.

[RGL]

And later; the tracks, I just need to sand down these little injection ports 

[FriedClams]

Very interesting build you have going here Greg, and I’m really enjoying your log. Like the round modeling vice.

Finally, I’ve added the curtains that appear  on every one I’ve seen. Paint next.
