I have to admit, I was a bit skeptical about the grey engine, but, not now, it is perfect, the contrast looks spot on, and from some of the old school English engines, it looks right on to me.. I LOVE that !

Thanks Jeff! The instructions say the engine was either the grey I did mine or the same as the chassis colour. I decided on the grey to break things up a bit.

The next bit is where things got a bit fiddly. I had to assemble the winch and then install it. There's a lot of small parts here and some have to go on in a certain order. For example, the spool is placed into position in halves, then some guides are added and then the top of the spool. 

The other bit was getting the position correct on the frame. I didn't do myself any favours by accidently sanding off the locating tabs. 

But before that, I installed the driveshaft.

And painted the cabin floor and gave it a wash.

The floor will then get painted in the cabin colour and then worn to show the wood effect.  I hope. 

Back to the winch, here it is installed. I didn't grab any pics while assembling it as I wanted to make sure it all fit together correctly.

There's some touch up needed in a couple places and then some weathering.

I applied some chipping fluid to the cabin floor, gave it a coat of desert yellow and then scrubbed away.

I think it turned out ok. 

Next up was the really guide pulley and the base for the hitch.

I couldn't help it and decided to see what it might look like finished.

With the Grant loaded.

I'm going to try and find a suitably sized pice of brass tubes to replace the plastic rod on the hitch. I think it'll be more durable in the long run.

Rigging! Wait, there's no wings on this sucker what gives?

Got to work on the various tow cables, starting with the main one attached to the winch. Thunder Models gives you some general instructions on where to route the cable but the videos I posted earlier really help to clarify things. 

For example, I most likely wouldn't have passed through the set of rollers in front of the winch.

Hopefully there's enough cable to get through the pulleys on the trailer and connect it to the towing harness.

Your applied mechanics look great. That set of gears is fascinating, I hope not too much of it will be hidden in the end.

Cheers Rob

The whole kit is fascinating, the level of detail is crazy, and yeah, I agree, Carl got the mechanic of the system right on..... I have a silly question... the rollers up front that are horizontal, what would they be used for|? I thought they maybe should be vertical, so the cable rolls onto the spool so as not to get fouled in the gears etc ? Not being the least bit critical, they just look like the should have a cable thru them..... sort of as guide rollers? Or is there a vertical cable connection? I'm curious............  I still can't take my eyes off that engine...... it ski a work of art... I love that

Thanks Rob! I suspect much of it won't be seen as the cab covers most of the winch. Maybe from underneath you might be able to see a bit more.

Thanks Jeff! The horizontal rollers are indeed  guide rollers. There's a third one underneath the two in the middle so the tow cable rolls feeds between them. This isn't covered in the instructions but the video showed it that way and it does make sense. The spool still rotates so I can take up the slack if any once the trailer is attached.

I've been trying to decide how best to weather the trailer. 

I finally decided to partially strip the deck and put a coat of silver down, then cover that with the camo and then wear it down to the silver. 

I used Tamiya lacquer thinner to wipe off the paint from the deck. I figured I didn't have to be precise as it's all eventually getting the same colour over top. 

IMG_20200828_120013.thumb.jpg.5caad69552b189deabecaecd403aa918.jpg

I then sprayed a coat of Tru Color metallic silver. 

IMG_20200828_120922.thumb.jpg.34d38ca8df90aa0a334df89fc7085e6c.jpg

Once that dries, I'll get a top coat on.

Do I hear hairspray ?:D

Cheers Rob

Actually, I'm thinking clear coat, then colour coat and finally a very gentle sanding. It'll give it more the worn away look rather than chipped finish. 

I've done it once before on a Corsair and it worked out well then.

Sorry, Carl, I didn't see the single roller under the two top ones............. I will go back to my seat and watch with great enthusiasm, as this awesome build continues..... you're nailing this build, Bud....

It's all good Jeff. It's hard to see as is.

Here's an even better view as it snapped off when I was trying to change the cable for a longer one. 

IMG_20200829_110047.thumb.jpg.404555cdeef6981d4b61e9d890bf5ff5.jpg

 

Thankfully it's a clean break so won't be too bad to glue back in. I will wait on that until I have some suitably long enough cable and can confirm it'll fit between the rollers. 

Watching the video again and reviewing the instructions, the amount of cable they give you in the kit isn't anywhere near enough if you plan to have a loaf on the trailer. There's about 25cm of cable (rope actually) in the kit and you need almost double that if you're doing a 3:1 winch like in the video.

Thanks Harv! 

I guess sort of? Don't want to build anything with wings at the moment still but do want to work on stuff if that makes sense. 

The Scammell certainly fits the bill and it's been fun to work on it.  Same with the Grant, tracks and all.

I've got some new cable that's longer ordered so while I wait for it arrive, I'll continue with the trailer and Grant. 

The trailer had a couple racks that go underneath. They're supplied as multiple parts of PE that need to be assembled and then glued into place. 

Here's the rack for the gun planks.

Starting the assembly. 

IMG_20200829_153818.thumb.jpg.0827fd67676176c68783e5c7fe4801dd.jpg

One thing not mentioned in the instructions is that the lateral supports are not symmetrical. I initially ended up with the end pieces oriented correctly but the middle one was backwards so I had to remove it and reattach it correctly.

Here's both racks in place on the bottom of the trailer. I've also added some of the other remaining fittings.
