Oxford Diecast JCB C3X 1980s - Step 3. A Light Coloured Pigment.

Mick Bonwick

174 views

The application of Europe Earth pigment is intended to represent a dusty coating of dirt picked up while operating in a relatively clean, but damp, area. The pigment was applied using a filbert brush that had taken powder from the lid of the pot. The vehicle was laid on its side and the brush held above each wheel in turn, and the brush tapped gently to dislodge the pigment so that it fell into the still wet wash from step 2.This conglomeration was then left to dry. The inevitable additional deposit on the tyres was deliberately left to discolour the rubber.

 

The remaining pigment on the brush was then gently distributed onto areas such as the cab roof and engine cover, by simply dabbing the brush onto the relevant areas.

That looks great as it is! Fantastically dusty,

Watching with great interest, I attacked one of these a few months back.  I went from more of a ‘rustbucket’ look, aiming for a machine that’s been exposed to the Cumbrian weather and suffered accordingly.  One thing I would suggest is that if you’re planning on posing this with the back actor in the folded position, there’s too much metal in the top pivot for it to fold up correctly.  I scalped some out with a burr in a dremel, to allow the boom to fold up a little further.

Incidentally, where are you getting that pigment from?  Fancy having a play with that.

 

Keep up the excellent work, looking good!

Hi Owain,

 

I don't plan to pose it anywhere in any position. This is a weathering exercise.

 

I suppose I could nudge it in an appropriate direction, though, even if it isn't a canopy. :)

 

The first step in the series mentioned the name of the pigment, and if you enter that name into your favourite search engine you will receive several supplier names as a result. I can't remember which of them I bought it from - it was a while ago and my memory isn't as good as it used to be. At least, I don't think it is.

Hi Mick,

 

Cheers for that, that’ll teach me to read from the beginning!  I’m rather taken with the effect of the pigment on the tyres, looks just right for aged rubber to me.  Most of what I’ve tried had either no effect or overwhelmed.

It's a good idea to prepare the surface before you place any pigment. A shiny rubber tyre won't accept pigment, so I spray with a coat of Testor's Dullcote. Once that is dry (10 minutes maximum) the pigment is added in SMALL quantities at a time. You will see from previous articles in this blog that my method of making things dirty never involves very much at all in the way of materials. This process also reduces the chance of overwhelming. ;)

 

Here's another example:

Aha!  That had not occurred to me, I’ll try that.  I browsed your other work last night, I’d seen the other JCB.  I also liked the Ferguson Land Rover, very taken with the delicate effect.
