Des Delatorre International Memorial Group Build / Re: LVA Fokker D.III using 3D prints designed by Bo
« Last post by IvotB on Today at 08:30:45 AM »Steven, I hope to be able to show that it can be done, but it is all pretty tiny and requires careful handling.
Some additions to the cockpit:
Bo designed some niceties. Here you see the cockpit floor, the rudder pedals, three parts to build the compass and the top of the control column.
The challenges here is the top of the control column. Don't cut anything from it's 3D base, but first drill a small 0,25mm hole in the handles and bend and fit some 0,25mm wire inside. In doing you also glue this wire unto the middle part which is the button for the MG's and underneath connects the handles to the column. Do that all when these three parts are still connected to the base and after the glue has cured carefully cut the parts off.
It all requires a lot of painting still, but here you get the picture how it all fits in the cockpit:
I couldn't resist trying to fit some other parts to get an idea about the finished model.
If I can manage to make control wires running through the fuselage at least the rudder will be controlled from the cockpit. The control stick cannot move the elevator as it doesn't move to the front and back. In theory controlling the ailerons is possible.
regards,
Ivo

« Last post by lone modeller on Today at 07:18:32 AM »Evening All,
Many thakns Prez, p9o1rische,Rick and Giuseppe for the very encouraging comments: I really appreciate you people who drop by and leave such positive comments.
Roberto: I did know that the photo to which you refer was of a torpedo bomber, but I did not know which unit the aircraft belonged to, nor did I know about the squadron commander. Thank you for the information: it is truly surprising what one can learn from others simply by building a model!
I have been working on the fuselage nacelle - trying to make a decent gun ring on the nose and add some radiator cooling vents around the front end. The Ca 5 was a trimotor like the earlier Ca 3, which presented the designers with the problem of how to cool the pusher engine at the rear of the fuselage nacelle. The answer was to mount a radiator in the extreme front of the nose and pump the cooling water from the engine to the nose and back again. It does not require a degree in mechanical or thermal engineering to work out that this was not an optimal solution: the type was not a success in part because of the overheating problems associated with the engine mounted in the fuselage. However that may have been I still had to add the coolig gills to the fuselage (and will have to add more later to the booms when I get around to making them). I decided that if I cut and glued strips of 10 x 20 thou strip in the right places and then used a file and glasspaper to shape them I might just get away with something resembling said gills:
I have also built up the nose for the front gunners gun ring with a plastic disc which was cut and filed to fit the nose position. Filler did the rest: you can also see the filler around various parts of the fuselage mouldings where trimming and small errors needed correction. When all is primed I am hoping that the blemishes will disappear.... we will see.
I decided to apply more to 10 x 30 thou strip and add the ribs to the wings. For those who may not know of this technique (and I am constantly asked about this at model club open days), here is a brief description:
I mark the positions of the ribs with a pencil on the wings, tail surfaces, ailerons, elevators, rudders, etc as appropriate. In this case I am using 10 x 30 strip because this was a large aircraft and the ribs would accordingly have been wider. On smaller aircraft I use 10 x 20 thou strip, and on larger scale aircraft I use larger strip suitable for the scale.
I cut lengths of strip which are longer than the chord of the surface to be covered. I apply liquid cement liberally along the pencil line and quicly lay a strip directly on to the line and gently press it down with the end of a nail file of other suitable hard, flat tool.
When all of the strips have been applied and the glue allowed enough time to dry I check each strip by trying to push it gently sideways. If any section of strip have not adhered properly I apply more cement to the areas which have not stuck down.
When the cement is dry and all the ribs are firmly in place I gently rub them along their lengths with fine grade glass paper to take off the sharp edges and give them a rounded cross profile. Finally a couple of coats of primer ensure that any small gaps or blemishes disappear.
This photo shows some of the strip being applied to the lower wing and one of the ailerons: the yellowish strip will be under the fuselage nacelle so if it is visible later the bright white plastic surface will not show.
Waiting for liquid cement to dry can be tedious so I started to build one of the engines (there will be three eventually). The engines were 6 cylinder Fiat A 12 inlines developing between 200 and 300 horse power on the early variants: later machines had Fiat Isotta or Liberty engines fitted. The differences between the original and later Fiat engines are not really apparant in this scale so I made one using plastic rod of different diameters, strip and bits of sheet - some of the latter was laminated to make the engine block/sump. The components look like this when laid out:
and like this when glued together and painted:
Only two more of those to make now, but at least I know how to do it so they should not take too long..
The next update will be delayed as unfortunately I have to go on my travels (again) for a couple of weeks. But if you have been, thanks for looking.
Stephen.

« Last post by lone modeller on Today at 04:35:40 AM »I have only just founrd this!! I have not seen 3d printed models before so I am very interested to see how ti sone proceeds - if what you have done so far is anything to go by, it is going to be a first class model in every way. A lot of scratch building techniques needed here but looking at your locos this will probably be something of a walk in the park for you.

« Last post by IvotB on Today at 04:00:39 AM »Thank for the encouragement.
I have already done some additional items. I'm running behind here because I'm using Flickr as my photo website and they have had (and still have) a lot of problems with their website and service.
I have tried to fit more parts to the fuselage. One of the issues that need attention is the fact that the 3D prints do not always have an even surface as they ar printed in layers. There are already other techniques available, but this is if the layer kind. I was very suprised though the really small details are being reproduced like for instance small holes in the main wing girders. Holes with a size around 0,3mm which I find pretty good.
But the surface effect can be seen here. It is already sprayed with primer and before I gave a treatment with a glass fiber pencil, but I will have another go at it:
In the front there small pins thatb are going to support the MG supports. Bo recommends to drill a hole of about 0,25mm in them and that proved to be possible.
I just put Gaspatch MG's on top to get an idea:
The ammunition bins have also been added in between the frame of the fuselage.

Ivo
