With wet weather imminent, I decided to make hay with the day as mentioned to John in my previous.
Frankly, I’m not sure whether it was worth it. Bit of a mixed bag of results to be honest; more bad than good.
I started applying varnish to the posts last night in order to provide maximum time for going off (usually two to three hours at room temp.). Mixing the Tamiya Clear (flat) with their thinner X20A, 1 : 3 , it went on without blooming, so starting earlier today, I applied a second again without bloom. Then later this afternoon, I applied a third and final coat; you’ve guessed it: bloomed….. I think with the frustration experienced in between coats, I rushed it. Never mind, it adds a sort of fading to the finish (although too much on the weighted arms) so I’ll just have to like it and lump it.
Ordinarily, I wouldn’t have bothered with varnishing however, the coats of paint have been kept intentionally thin to achieve my aim of a weathered appearance, thus will mark at the slightest touch. As I’ve to reassemble the parts after painting it’s Sod’s law that the paint would succumb, hence the varnish coat. Anyway, to show you what I mean:


I’ve convinced myself it’s weathering…….
Elsewhere, I attended to ancillaries such as the ladders. Masking off the bases of each (apparently some signal ladders were white at the base), I mixed up another coat of Vallejo and Tamiya to make bauxite as before, only this time I made it slightly more concentrated. Pressing the trigger of the gun, nothing happened. Then bubbling in the vase/cup but nothing coming outside of the spout. I realised it was blocked. I upped the pressure: still nothing. Then I removed the nozzle and sprayed again. This time it spurted out but in spots. Suspecting I hadn’t cleaned the gun sufficiently after the (thin) varnish coat, I emptied the cup, took the whole darned thing to pieces and cleaned it again. Another mix, and this time it came out first time. But still bitty and spotted. I realised the problem straight away: the Vallejo in the Tamiya mix of flat brown and X20A didn’t like the thinner. Frankly, I suspected when mixing yesterday’s bauxite with these paints for the first time that I was pushing my luck and don’t know how I got away with it. Still, I needed to get the ladders etc done, so persevered with a weaker mix of the same. After cleaning the airbrush once again (this is the bugbear I find with air spray guns; spend more time cleaning than spraying) I tried again, but sadly the paint split again. My wife was out with the car so a quick visit to Hobbycraft for a suitable shade of Tamiya was of the question, so into the workshop I went to dig out a brown in Vallejo. I had several acrylics in brown including Humbrol and AJK(?) but no Vallejo. In the end I opted for a Golden Brown from an Air Master (?) set and went for it, mixing the colours with deionised water (after cleaning the air brush yet again….). To be fair, it was a close match but erring on the side of caution it was as weak as maiden’s water. But I’d had enough by this time and applied several coats. They’re okay I suppose, but not really what Ai was aiming for. Hopefully the white bands at the base will set them off.
Late afternoon I decided to call it a day (after cleaning the brush again and applying the disastrous final varnish coat yo the posts) and decided to leave putting the equipment away until after I’d eaten. Just needed a break from it.
Intending to tidy up after a meal, the thought of imminent rain had me reconsidering: I still wanted to break the back of painting the rear of the signals and the loose wires. As it was just black I needed for now, I figured I was in for an easier ride with just the Tamiya black. And so it proved. After cleaning up the gun for the umpteenth time today, everything is back in the workshop (and Olive is back in his vivarium overnight, protesting all the way after camping out for so long!) so the weather can now do its damndest.
I suppose the lesson here is stick to like with like if you want to avoid disappointment and using up copious amounts of isopropyl alcohol, as well as valuable modelling time.
Oh yeah: and don’t start a task if you ain’t in the mood. Phil O was right once again about that. Why didn’t I listen……….
Cheers for now.
