I created this blog because I could not find the kind of tutorials I needed for some models and miniatures I wanted to build. I hope it will be a useful source of information for anyone who may experience the same lack of first-hand, step-by-step reports.
I am not an expert by any means, so feel free to comment my posts or to contact me to share your advice.

Carbon fiber decals

Yes I know: I usually complain about how difficult I find to place the supplied decals, and now I want to put CFRP decals everywhere... No logic here, but only the wish to get one more notch in detailing the kits. CF decals come in plain sheets, mine were bought at Scale Motorsport. They keep decals for the main modelling scales and have different weaving patterns. I chose one which is quite common (1000 series) as I wanted to try it on a few selected parts, but others are available in different patterns and colours (to simulate aramid fibers for example). There are some bits of advice coming with the decals and they prove quite useful.

My first trial is on the endplates of the front wing. The outside face is painted dark green but the inside one shows the base material. I used the Formula Perfect book to find the general orientation of the fibers. Since there is no template, the first thing to do is to create one. In order to do so, I put a piece of masking tape over and around the shape of the part to be covered. I cut it out directly on the part and then place the tape on the decal sheet and then cut out the decal. After the mandatory time in warm water and the usual soaking of the surface of the part with Microscale softener, my first surprise was to see how thick the decal is. With thickness usually comes stiffness and I suddenly was confronted once again with what I hate most about decals. How will that stick to the part, and with how much damage will I end up? The vortex generator of the end plate was indeed a challenge and I wanted to find out what gives better results: a larger excess piece of the decal or a smaller one. How will either wrap around the bulge of the part?

I was a bit disappointed to see that the softener did not seem to have any effect on the decal (thickness at play here again). However, the use of a hair drier (at lower setting) made wonders! Used with a Microscale soaked cotton swab to push the decal around the part, everything took its place with no fuss. A dry swab was useful to remove bubbles and creases, and now the thickness had a positive effect: the decal is strong and does not want to tear easily. It showed me that a smaller surplus of decal was better: the larger one has to fold over itself. I am not really bothered by that since I wanted to put CFRP decal only on visible areas, thus excluding the underside of the endplates. I finished the job with the larger, flatter pieces, which were much easier to put into the right place.

Masking the body (red areas)

The relative ease with which I cruised past the first masking stage of this model backfired in a twisted way once I decided to prepare the parts for the red paint application. I used the same method as for the green areas: a first counter-mask identical to the decals supplied with the kit, to be used as a guide for the actual masks.
First, it took me a whole week to get things right. On the one hand I am dealing here with continuously curved surfaces, there is very little aid to place the decals or masks correctly. I have the feeling that one of my masks used on the Lotus 49 was not centered on the nose cone and I did not want to repeat history. So I tried and tried again until I found something hopefully suitable. The engine cover and the sides of the cockpit were easy to deal with and the main challenge was the nose once again. I could use the Castrol logo found at the tip of the red stripe as a gauge for the width between the masks, but it had to be placed evenly from right to left and exactly perpendicular to the axis of the body. I find it difficult to be sure and the next un-masking operation will tell...
On the other hand, it looks like the decals supplied are a bit larger than they should. I am convinced that the bottom of the green area is too low. If I want to keep a white separating stripe which will look proportionate with the model, the top of the red area will also be too low. That should translate in the Loctite logo being partly on the side pods, where it should not be. Once again, time will tell...
This time I chose to keep the whole front of the model assembled before being painted. Runs of paint will give me hell for it I am sure!

Green areas

The Park Green spray paint is easier to use than the white paint. It covers the model much more and is more opaque. The masking tape was removed without any difficulty but revealed a few surprises. I did not mask the sidepods enough and some spray went onto areas whcih should stay white. I guess I will have to brush some touch up eventually. Same story at the border of the masking tape: there are a few runs of paint but nothing too disappointing. I sanded the edge of the front suspension cover: as layers of paint tend to accumulate, the fitting of the parts is a bit impaired. Anyway, that part will be cemented to the cockpit, so I do not need to care too much about the interior of it.

Formula Perfect Manual

The early 1990s are definitely somehow pre-historical. No internet with Imageshack or Flicker or any image bank, no digital photography, merely magazines and VHS tapes to get visual references. At that time Tamiya was in full swing with their 1/20 F1 models and they published a few books full of close up pictures for some of their kits. I recently got this one, 5th in the series, to help me with my new kits.
Those books are today somewhat hard to find, except at Mac's, on-line shop which I have just discovered and now heartedly recommend for modelling supplies. So here's to you and your great sense of customer care Ian!

Front wing

Good intentions do not always pay off. I tried twice to build the 107B with the decals and twice I made a mess. I hate large decals, simple as that. Here are the front wing elements with their decals on and even those I cannot get right... I removed all of that in warm water with a shot of vinegar (I placed them a few years ago) without any problem. Of course, the second picture is the new end product with new paint and new decals. Needless to say that I am quite happy with that.

Primer takes place before nice coats of hard paint. The lower front wing is painted Camel Yellow (TS-34) first. The end is then masked and the rest painted Racing Green, as well as the outside of the end plates and the flaps.


When I removed the masks on the lower lip, I found out that paint eventually found its way under the tape (not a real surprise, I am anxiously waiting for what it will look like on the cockpit) and I had some touch up to do. A smooth sanding of the extra green paint resulted in making the primer visible on the edge of the area where the nose will be attached. Fortunately I had some Golden Yellow from Citadel, which is quite close to Camel Yellow, but flat. Hopefully it will not show after a few coats of clear.

I used decals to finish the wing: the Good Year ones were not a problem at all. Then I cut out the blue stripes from the main decals of the flaps and finaly the Burmha logo. It is fascinating to see that the Camel Yellow and Racing Green match the colours of the original decals, with more shine as a bonus. So far clear coats have not messed the decals like with the Lotus 49, and I am glad because that would have meant that another kit would have to be bought to start again (for what? fourth time?).

Masking the body (green areas)

Working on both a 1960s and a 1990s Lotuses makes it obvious how things became more complex at some point in time. The body of the 49 is merely made of two separate elements: a nose and a cokpit. The body of the 107B is made of a nose, a cockpit, a front suspension cover and an engine cover. Anything different from a plain paint job gets very complicated very quickly!
I had to assemble some of the parts together in order to do the masking and make sure that there would be perfect joint lines between every body components. The decals were very useful to get the right shapes and to help to place the actual masks onto the body.
My fears are about paint running under the masks, and I do not think that I will be able to prevent them. I also think that I should remove the front suspension cover to paint it apart from the cockpit. Odds are that the paint will cement both elements together and even the sharpest blade will make a mess of that.

Preparation and primer

Priming is now a classic operation, so here it goes on the various parts making the body of the car. Prior to that, some adjustment has to be made on the two halves of the cockpit. Careful cementing (alignment is important) goes with some repairs on the joint lines and some sanding to prevent huge gaps between cockpit and nose and cover. I am proud of what I did on the front suspension cover: it comes with two holes for the antenna, but one has to be removed. I, for once, did a great job cutting it off with a very sharp blade, as close to the surface as possible, and then sanding the part to level things. Then mist sprays and thin sprays will get me going.

New Lotus to hit the workbench











Here we are again! It looks like springs awakens in me the will to work on models. It could be seen as an ideal winter hobby, but I always come back to them around Easter. This time I wanted to go back to my late teens and build again my first two Tamiya kits: the Lotus 102D and Lotus 107. It was 1992 and I was cheering for the F1 team, getting the 102D at my hobby shop and waiting anxiously the end of season for the release of the 107. The year after came the Lotus 107B, and I will use it as a test, a bit like the 25 before tackling the 49. It is quite convenient since this kit is still available. I managed to get a hold on 107 and 102D kits thanks to e-bay.
I still have my models at my parents' home. I even have pictures of them. Get me some tissue for me to dry a bit because those were old times when paint had to be applied with a brush, and only a brush and when I used vinegar in place of Microsol because noone told me about it. I should say I am glad to have made some progress since then, but it was a world to discover and I had my dose of challenges, stress and disappointment. I guess I should not write that, but the kits were built without paint on the yellow areas (hey, the plastic is yellow, what is the problem?) and all the decals were used. There are pin holes where trapped air was inevitably found, and do not even think of opening the engine cowls or everything breaks apart...
My goal is obviously to build them again but by using what I learnt on the 49: spray paint and masks. With the 107B, masks will be somewhat complex and challenging, especially around the cockpit. I also expect to try my hand at pinstripes.
