Construction Continues

 

The first part of Phil's Halifax article may be seen here.

Tailplanes

Strangely, these were the first parts that I made. I tried forming them at first by sanding from solid, but was not happy with the results and used what has become my preferred method. A profile was cut out of 0.5mm plastic and all the individual flat faces added. With the metal plated sections finished attention turned to the fabric covered rudders. All the individual ribs were added and sanded to size. The sagging between the ribs was simulated with Miliput gently smoothed with a wet finger until the desired effect was created.

On the Halifax, with most of them being painted black, the effect was quite hard to see, but on photos of a silver painted one it was very apparent.

 

 

The rudders were then sprayed with grey primer and the metal areas polished. The fabric areas were polished less so that a difference in texture can be seen. The tailplanes and elevators were done in much the same way apart from the fabric covered elevators. These do not show any sagging between the ribs. The elevators are almost totally flat with only the metal rib tapes visible. To simulate these grey primer was sprayed on to decal film and thin strips cut out and applied.

 

 

Once over sprayed with primer these sections were again worked so that the difference in texture is just visible.



Further interior detailing

Work continued on the two fuselage half interiors.

The flare chute was replaced with a more accurate version, not that any one will be able to see it once the halves are together. The area behind the Flight Engineers section is mostly complete now and as we move into areas that will actually be seen the level of detail will move up a degree. This means that I am going to have to do some etchings. The problem with this is that if you want to get them done professionally then you need artwork for pieces that are some way ahead of where you actually are. The first part that I etched at home was a gate for 6 levers in the F.Es station. This was done by cutting out a small piece of brass slightly larger and twice as thick as the part required. One side was coloured with a permanent marker and allowed to dry. Apply black to the front face only. As the acid etches from the back it reduces the thickness by half. This way you do not need to register the design on the back face only the front. The areas that needed to be removed were then scratched into the black using a needle in a pin vice and a magnifier. This was tricky as the part is actual size (5mm x 3mm with six slots in it) and it took a few attempts to get it right .The part was then dipped into the etching liquid and agitated for about 10-15 mins . Once washed off the part was cleaned up and a reasonable part had been made. You cannot get the detail or finesse of parts made from photo reduced artwork but for the simpler parts it works fine. I was going to produce artwork on my computer but it was taking to long (not that good with computers) so I am doing them the old fashioned way by drawing them out at 8x size and pasting to form a piece of A1 artwork.

Simple rules are; Black (nothing removed either side) Red (half etch front face) Blue (half etch rear face) white (etch through both sides). Then find out your minimum line thickness for the drawing which would typically be 8x the thickness of the brass being etched, so on 10 thou brass the min line thickness on the artwork should be 80 thou. Red/blue areas should be all colour with no black outline.

I find it easiest to cut parts out of coloured paper and paste them into the main page. Once your artwork is done a reduced photo negative/positive (cannot remember which) is made and the sheets etched.

Remember also that when drawing components like instrument bezels to actual 1/48 size that it can mean that they will not fit into the space on the panel. The panel itself WILL be undersize because of the thickness of the fuselage sides not being scale thickness; this also applies to your injection kits. This is where true scale goes out of the window and it becomes a matter of finding the proportions of each piece within a certain space.

 

 

Shown above is a first try at producing a basic layout for the F.E panel drawn in MS paint


The next series of pictures shows work progressing into the F.Es station. Lots of head scratching as there were a couple of spots I did not have covered by photos. In the end it came out okay.

The wiring is a mix of Miliput, lead wire and copper wire. Miliput is ace it lays really naturally in a way that I find that I cannot get in copper. Lead is somewhere between the two in terms of ease of use. You can get the lead and copper wire from fly fishing shops. Get the lead wire its good! One great property of the Milliput is that you can roll it to the very diameter that you need, useful as in the photos below I had to get a certain number of wires into a set space.

It can be very carefully applied soon after rolling or left for 20 30 mins to stiffen up a little. The detail parts below are made in the usual way from evergreen plastic rod/strip etc.

Next, the bulkhead between the pilot and flight engineer was detailed with some rivet detail and plastic strip.

After this, a start was made on the pilots seat. I found some great pictures of a pilots seat that has been rebuilt. Thankfully one of these was a straight on side view. After a whole evening of gazing at the pictures I figured out how to make it. Using tracing paper the outline of the side plates was drawn. I knew what size that I needed the seat to be so I worked out the ratio that I would need to reduce it by. I scanned the drawing, reduced and then printed it out using my copier. Once done a template was made and the two sides cut out of plastic card. For the seat pan a small master was made and a plunge moulded again in plastic card. With the seat pan and sides joined together the front and rear plates were added. For the beading around the seat pan plastic rod was used for the straight sections and lead wire for the semi circular cut out at the front.

Next to be added will be the tubular support for the backrest, the backrest itself and the harness and attachment points.



Next time...

More progress on the floor insert and pilots area
