try these 2 little gems from Randy - you'll feel you know what I mean after watching these

Well I ready dont know what to think of Mr Copper, he has an unique way of promoting his kits and what you can do if you don`t like them. :lalala:

Looks like you have a few more hours of fun still to go, good luck.

So, Saturday and Sunday turned out to be very dusty days of trimming and sanding (not helped by the wind and drizzle) - that belt sander was worth every penny I paid and has very quickly brought me to a position whereby I can actually start assembling the thing. Boiler suit, goggles and face mask kept me safe from the mess - although I did notice the end terrace house next door now has a lovely yellow film of dust stuck to it where the wind and rain carried off my waste.

Not a single tread tooth broke off in the trimming process

I had to drill out 10mm of resin so the corridor insert could be installed - the picture below shows how the moulding is supplied if you refer to the right side which has not been drilled out

I spent an hour or so fiddling around with my Pegasus Hobbies Shark diorama and have only ended up working on the crawler for a few hours this week - but its time for the sticky expoxy stuff as I'm ready to assemble

 

The base marked up and drilled out for the underside down-lighting

Having trashed the bathroom while dipping in hot water, I have the side walls clamped flat

 

DSCF7337

 

The chute - the sucking thing that sucked up R2-D2 - custom made with some clear 10mm Perspex rod I had spare

 

DSCF7338

 

yet again, those cheap clamps from Gibraltar Tools Ltd have once again saved the day

 

DSCF7339

 

DSCF7340

 

Luckily, its the weekend soon and I hope to get sticking more of this kit together

 

Thanks for crawling along with the build

A trip to Halfords for some primer set me way on the way this weekend

 

DSCF7347

 

Fine Moulds X wing kit has a spare R2 unit - perfect (OOTINI !)

 

DSCF7344

 

the room up front and up top - painted as much as I felt needed given the likely lack of internal visibility

 

DSCF7341

 

Fibre to the controls and walls. The fibre end tips (i.e. the end that will glow, has been heat sealed with a hot knife to keep the fibre snug in the aperture of the dial hole.

 

DSCF7342

 

DSCF7343

 

Bulb and soldering test

 

DSCF7348

 

DSCF7349

 

DSCF7351

 

none of the fibre cables have had red, yellow, orange and white bulbs attached to them yet however the rear blue bulbs seem to be adding a nice backlit effect early on in the doorway - a film of frosted diffuser material is added behind the doorway

 

DSCF7356

 

Tumble dryer engines ground down and ready to assemble onto the rear end - Gorilla grip epoxy resin used

 

DSCF7357

Thanks for following - John

A touch of add-lib pipework added using lead wire and copper tubing - I'm not sure I will keep the upright exhaust, but for the moment I'm liking it as the back end of the crawler is missing a lot of suspended and supported pipework that could not be cast in single resin mouldings.

 

The outside track tread cover plates - piping attachment points drilled out and lead wire trips of 40mm inserted

 

DSCF7362

 

DSCF7363

 

DSCF7364

 

DSCF7370

 

The backend - various thicknesses of copper tube added

 

DSCF7361

 

DSCF7360

 

a coating of primer added now

 

DSCF7367

 

DSCF7368

 

DSCF7369

 

Onto the top now - the roof plate also includes mechanical exposed parts - the 0.5mm holes that have been drilled out are for fibre optic lines to add light into the recessed panels once inserted behind the roof panel

DSCF7366

 

Thanks for crawling along once again here.

The brass pipe work is fantastic, its a shame to cover it in paint.

its Ok rockpop - Super Mario will be back to polish up the plumbing once it has its top coat, the copper needed priming as it was greasy and fogged from the superglue vapours

I spent a good few hours in the workshop over the weekend - and have made some good progress although most of the time was spent lighting and wiring or waiting for the epoxy resin to dry / resin to reshape after heat treatments etc

 

side panels drilled and screwed in for added bond

 

DSCF7371

 

glued and clamped - screws added at rear lower lip to mount the rear section onto

 

DSCF7372

 

The rooftop engine housing - lead pipe added for some extra effects - holes drilled for extra fibre optic lighting

 

DSCF7373

 

some of the internal doorway and corridor lighting work - blue LED and amber bulb fed fibre optics added

 

DSCF7374

 

DSCF7376

 

Fibre optics added to the roof engine housing area

 

DSCF7377

 

The rear end with final pipework and kit parts installed, and 2 x amber LED bulbs installed on extraction fan heads

 

DSCF7379

 

A classic example of why working in 7mm thick resin panels has its draw-backs - this crater was unavoidable - Randy Cooper identifies it in his instructions expecting the modeller to use filler. I have other ideas and had already invested in some plastic strip to add as a rim over the whole length of the top rim

 

DSCF7380

 

upper exhaust port LED lighting and doorway / servicing panel fibre optics

 

DSCF7381

 

 

DSCF7382

 

2 x yellow LEDs installed in the entrance corridor

 

DSCF7383

 

 

DSCF7384

 

LED holders fitted for the underside down lighting. All the outside edges will have Amber LEDs, while the inner mountings will have yellow LEDs

 

DSCF7385

 

Fibre optics and LEDs now installed to the mid panel corridor channels 

 

DSCF7387

 

Clamping in 3 strips of 2 x 1 timber to each side panel to help keep these side walls from any further bending or shape distortion

 

DSCF7388

 

forward lower entrance doorway inserts glued and LEDs fitted

 

DSCF7389

 

The Headlamps - Amber on the Right side (outside bulb), yellow on the left side (inside) - same on both sides

 

DSCF7391

 

 

DSCF7392

 

The timber strengthening strips in place after 10 hours of drying

 

DSCF7393

 

boiling water and clamping the rood panel flat

 

DSCF7394

 

The above picture shows the fitting strips on the inside panels that will house the wall spars

 

that's all folks - John

WOW, really coming along nicely. I can't wait to see this all lit up. I'm just gutted I can't actually walk through it. With the timber supports and all the wiring in addition to the huge pieces of resin, how much do you expect this will all weigh in the end?

Cheers for the words - it'll weigh about a Stone all in - I just hope the treads all hold up under the weight - I may have to hide a central support

Amazing!!!! But sorry! too much resin for me. I would have never gotten it, if I knew it would be this much hassle to clean up. No offense to Mr, Cooper, who is one is a legend in the Sci-Fi film industry, but it is too much work to clean, before starting to build the actual thing. On top of that, I am an asthmatic. The dust alone would kill me. :)

  • 2 weeks later...

Manbola took me out for a few days last week and I have only now managed to catch up with my camera's memory card for an update 

 

Despite the lengths I went to heat and treat the twists in the resin plates, this 7mm thick resin really wants to keep on returning to its original twisted form from whence I stored it through the summer - so, I have taken the bull by the horns and made wooden braces to hold this thing straight and correctly profiled - and its cost me loads of extra work and time, but who cares.. its all for fun after all.

 

upper frame template

 

DSCF7415

 

lower chassis lighting installed - upper frame wooden strengthener now attached

 

DSCF7416

 

DSCF7418

 

chassis side plates clamped on

 

DSCF7419

 

inside the crawler

 

DSCF7420

 

flight deck glued and clamped in

 

DSCF7421

 

more timber used to aid in retaining the contours and correct angles - turned out it also made a good battery support spar later on

 

DSCF7422

 

first fibre optic instrument and LED test on the control tower - looks OK, but there's nothing I can do now to change it if it hadn't

 

DSCF7425

 

DSCF7426

 

under the bonnet

 

DSCF7427

 

The Lid - I've cut the roof piece into 2. The forward section needed to be glued in place to keep the shape straight but this section made an ideal lid which needed some scratch build work to produce a light tight lip with locating pins

 

DSCF7428

 

DSCF7429

 

DSCF7430

 

entrance corridor section now glued in place underneath the crawler

 

DSCF7431

 

More Mario plumbing add-lib work

 

DSCF7436

 

This stuff is great for holding carpets together and dunking in liquid fibreglass, but also worked great to help hold the front section in place when attached

 

DSCF7437

 

DSCF7438

 

DSCF7439

 

so this is where those wooden frames turned out trump - no twists

 

DSCF7440

 

DSCF7441

 

DSCF7442

 

sorry ILM but I've started to stray away from where you left off a tad here - this external plumbing detail is addictive...

 

DSCF7443

 

That's all for now - thanks for crawling along once again here.
