Airbrush pieces in progress

Since I haven't posted any of my paintings on here yet.. I feel like breaking the ice from model making and share something else beyond making models and sculptures. Unfortunately I don't paint as much as I would like to, but one of my visions is to improve this skill dramatically over time, developing and experimenting with different free hand techniques. But fundamentally also taking my current conceptual ideas into another level and improve the way I express these into realisation both in 2D and 3D. These pieces posted here are only early stages, very premature in fact. But I'll be curious to document some of this at my early stages and see how it may all improve over time.. Also they're works in progress at different stages. And I may be posting a finished shot of each at some point. But this style of painting may well change in the near future.. I'm still experimenting and playing with things in this department..

Patinating brass etchings

For my latest architectural commission I suggested my clients the use of patinated brass to represent a specific material finish in the proposed building design, since they liked the idea.. We went ahead with it!

I particularly like this process and find it quite fascinating how the metal reacts to the chemicals. Specially the stage before the brass is totally patinated, half way through the process.. it goes through an unstable moment.. that was the point which I aiming for to remove the sheets from the acid. This 'half way" method makes the material 'roughly' or badly patinated (in the good sense though) giving the effect of random metallic toned reflections with some subtle blueish and red, brown tinted blotches.. Purposely avoiding the consistently patinated look throughout.. Which is of course another option! Depending on the requirements and purposes.. The full patination method is also a great option to represent bronze finished details in general, not just in models..

I hope the photos not only show what I try to describe above, but also the process from start to finish. I had to adapt the original cad drawings received by the architects, then sent it to be etched at 4D modelshop who were very helpful in delivering these on a very tight schedule! Once the cad drawings are modified and sent I receive the sheets in brass at 0.38mm thickness by request and the ideal thickness for my purpose. Then the patination process starts.. 3x trays were needed (acid resistant trays used for photography) 1 filled with rust cleaner (watered down), 1 with water and 1 with antique fluid (the patinating stuff!). 1st I dip the sheet in the rust cleaner of a couple of minutes rubbing in gently with a super soft brush to avoid scratching the metal.. this helps to clean any grease as this will show in the end result (finger prints..), 2nd I rinse it and dip it in water again roughly 2 minutes.. rubbing it gently on both sides, then rinse and dip it in patenting fluid for about 5 to 6 minutes to achieve the rugged reflective look.. if I wanted it fully patinated, this could be achieved in around 10 minutes. After patinating the sheets I dipped it one last time in water to clean off any patination fluid excess and rinsed it.. then cleaned it very well with much tissue until it's all dry.. left it to rest for 10 minutes +- and then treated it with 'liberon' Jade oil rubbed on a tissue, which seals the metal sheet and also prevents the patination process from being active in the longer run.. which is also an interesting thought! But not for this occasion..

I hope this post is constructive and educational as I personally don't see a lot of explanations or tutorials on how this particular process is done and I think it's something that it's relatively easy enough for anyone to do even from their own home. It's extremely effective and I really enjoy experimenting with this stuff!


Progressive aftermath!

From setting up my modelshop nice and tidy, ready to build a model for a very tight schedule.. and finally the result of how the place looked immediately after we completed the model! Now I've got some serious cleaning to do.. Ouch!

Realistically I needed 2 weeks to build this model, but I only had 5 days total and still receiving drawings in the last couple days.. In those conditions I was able to complete 90% of the model.. It was a very tough position to be in, because I either refuse the job since I will not be working to my ideal conditions and could't guarantee a complete model, in which the client gets no model. Or we both compromise... I did warn the client that we may need to accept some sacrifices and made him well aware of the circumstances. I would also doubt that any other more 'orthodox' model making companies would even accept such "impossible" brief considering the time schedule. I do have to mention that the client were superb to work with and they very supportive throughout the process. Full thumbs up to everyone who helped at Mixity!

The model will now serve its propose in the short term but I also have agreed to get the model back in my shop to finish it properly as soon as possible! In the the end this will be a beautiful model by the way.. With lights, patinated brass etchings and interesting architecture to mention some features.. It's all there, I just need to "polish" some edges.. 🙂


Some more car body filler and chemiwood models

I hope that by showing a few variations (as per previous posts) of different models that I've made by using filler and chemiwood as main mediums. I'm also trying to express the way in which we can use these mediums with such versatility.
